Ever wondered why some tiles are perfect for your bathroom while others are better suited for your living room? Understanding tile ratings and grades is crucial for making the right choice. Navigating the maze of tile ratings and grades can seem daunting, but it’s essential for selecting the perfect tile for each area of your home.
In this guide, we’ll explain everything you need to know about tile ratings, from wear and slip resistance to water absorption and breaking strength. By the end, you’ll be equipped to choose the best tiles for sale in Perth, ensuring your spaces are not only beautiful but also durable and safe. Let’s get started and make your next tiling project a resounding success!
What Are Tile Ratings and Grades?
When shopping for tiles for your home, understanding tile ratings and grades is key. Think of these ratings as a cheat sheet that helps you determine the best tile for each specific area, ensuring durability, safety, and overall performance.
Tile ratings and grades are essentially a set of standards that measure various attributes of a tile, such as its durability, slip resistance, and water absorption. These ratings are crucial because they guide you in selecting the right tile for different parts of your home, from the splash-prone bathroom to the high-traffic kitchen.
In simpler terms, tile ratings and grades help you match the tile to the application. So before you start your project, spend a little time understanding these ratings—it’ll help you make choices you won’t regret down the track.
Tile PEI Wear Ratings
The PEI (Porcelain Enamel Institute) rating is a crucial factor to consider when selecting glazed porcelain tiles for your home. It measures a tile’s resistance to wear and abrasion, which essentially means how well it can withstand foot traffic and daily use. Understanding the PEI rating helps you choose the right glazed porcelain tile for the right place, ensuring longevity and performance.
Understanding the PEI Rating Scale
| PEI Rating | Foot Traffic | Example |
|---|---|---|
| PEI 0 | No foot traffic (wall tiles only) | Decorative wall tiles in a living room or kitchen backsplash |
| PEI 1 | Very light traffic (e.g., bathrooms, bedrooms) | Tiles in a guest bathroom that isn’t used frequently |
| PEI 2 | Light traffic (e.g., residential areas with minimal wear) | Bedroom flooring where foot traffic is generally light |
| PEI 3 | Moderate traffic (e.g., kitchens, countertops, most residential flooring) | Kitchen floors that see a fair amount of daily use |
| PEI 4 | Moderate to heavy traffic (e.g., all residential areas, including entryways, some commercial spaces) | Hallways and entryways that experience frequent foot traffic |
| PEI 5 | Heavy traffic (e.g., commercial spaces, public buildings) | Tiles in a commercial lobby or a busy retail store |
How to Choose Based on PEI Rating
PEI ratings aren’t complicated, but they make a big difference in choosing the right tile. For kitchens, you’ll want to go with PEI 3 or PEI 4 tiles since they handle regular foot traffic and those inevitable spills. In bedrooms, PEI 2 tiles are a great choice—they look stylish while providing just enough durability for a low-traffic space.
Your front entryway needs something tougher, so look for PEI 4 or PEI 5 tiles. These can take the daily wear and tear from shoes, shopping bags, and everything else that comes through your door. For walls, you can focus purely on style with PEI 0 tiles since they don’t need to handle any foot traffic.
By matching each space’s PEI rating to how it’s used, you’ll get tiles that both look great and hold up over time. Just think about what happens in each room and choose accordingly.
Tile Slip Ratings
Slip resistance is crucial in spaces where water is part of daily life—think bathrooms, kitchens, and outdoor patios. Using non-slip tiles in these areas helps prevent accidents and keeps everyone on their feet, especially during those post-shower moments or while doing dishes.
When looking at slip resistance, you may come across three classifications used under AS 4586: the wet pendulum test (P0–P5), the oil-wet inclining platform test (R9–R13), and the wet-barefoot inclining platform test (Classes A, B and C). Each uses different test conditions, so the scales are not interchangeable. The right classification depends on where and how the tile will be used.
If you’re after tiles for your bathroom, our guide to non-slip bathroom floor tiles is a must-read. It covers the various finishes available, along with valuable tips on choosing the right tile for your space.
Wet Pendulum Test (R-Rating)
The wet pendulum test assesses a surface under wet conditions using a pendulum device fitted with a rubber slider. Under AS 4586, results are classified from P0 to P5, with higher numbers indicating greater measured slip resistance under the test conditions.
Understanding the P-Rating Scale
| P-Rating | Relative Classification | What It Means |
| P0 | Lowest | The least wet slip resistance within this test. |
| P1–P2 | Low to moderate | Progressively greater measured wet slip resistance. |
| P3–P4 | Moderate to high | Higher measured wet slip resistance under the test conditions. |
| P5 | Highest | The greatest wet slip resistance classification within this test. |
Although higher P-ratings indicate greater measured slip resistance, the highest rating is not automatically the best choice for every room. More heavily textured tiles can be harder to clean, while a rating that is too low may not suit the expected conditions. Match the tested rating to the exact application and follow the manufacturer’s suitability advice and any applicable building requirements.
Choosing the Right P-Rating
When comparing living room floor tiles, kitchen floor tiles or bathroom floor tiles, check the tile’s tested P-rating and confirm that the manufacturer recommends it for the intended location. A rating that may be suitable for a dry living area should not be assumed suitable for a bathroom, external area or another surface that regularly becomes wet.
Outdoor patios, pool surrounds, ramps, bathrooms and laundries do not all have one universal minimum rating. The appropriate specification depends on factors such as whether the surface is level or sloped, how often it becomes wet, the contaminants present, expected footwear and relevant building requirements.
Use the rating as one part of the selection process rather than a guarantee that a tile cannot become slippery. Check the product’s test report or technical data and seek advice from the supplier, installer or building professional when compliance is critical.
Oil-Wet Inclining Platform Test (R9–R13)
The oil-wet inclining platform test measures slip resistance while a person wearing standardised footwear walks on a surface contaminated with oil as the platform angle increases. Under AS 4586, results are classified from R9 to R13, with R13 representing the highest measured slip resistance in this test. R-ratings are most relevant to shod commercial and industrial environments where oil or grease contamination may occur.
Understanding the R9–R13 Ratings
| R-Rating | Relative Classification | Typical Context |
| R9–R10 | Lower | Oil-wet ramp classifications used where the assessed slip risk is comparatively lower. |
| R11–R12 | Higher | May be specified for commercial or industrial settings with a greater oil-related slip risk. |
| R13 | Highest | The highest classification for demanding oil- or grease-contaminated applications. |
Choosing the Right R-Rating
R-ratings should not be treated as a substitute for P-ratings or used as a simple scale for choosing tiles for ordinary household kitchens and bathrooms. They come from a different test performed under different conditions.
For commercial kitchens, food-processing areas and other workplaces where oil or grease is a foreseeable contaminant, use the project specification and the manufacturer’s test data to select the required classification. The highest R-rating is not automatically necessary for every application.
Wet-Barefoot Inclining Platform Test (Classes A, B and C)
The wet-barefoot inclining platform test applies to surfaces used barefoot and wet. A person walks barefoot on a water-wet inclined surface, and the result is classified as A, B or C. Class C represents the highest measured slip resistance in this test.
Where A, B and C Ratings Apply
These classes are relevant to aquatic and communal wet-barefoot areas such as pool surrounds, changing rooms and communal showers. They do not describe low, moderate or high exposure to cooking oil. The required class depends on the precise area and its use, so selection should follow the applicable specification and manufacturer’s test data.
Tile Scratch Hardness (MOHS Rating)
Let’s talk scratches. No, not the kind you get from your cat, but the kind that can mar the beautiful surface of your tiles. The MOHS hardness scale is your go-to guide for understanding how resistant a tile is to scratching. This is especially crucial for areas that see a lot of action or where heavy furniture might be dragged across the floor. Basically, if you want your tiles to withstand the test of time (and kids, pets, and parties), the MOHS rating is something you’ll want to pay attention to.
Understanding the MOHS Scale
| MOHS Scale | Tile Hardness | Example |
|---|---|---|
| 1-2 | Very soft, suitable for walls | Decorative wall tiles in your bathroom that look great but don’t need to take a beating |
| 3-4 | Soft, suitable for light traffic areas | Low-traffic rooms like guest bedrooms where foot traffic is minimal |
| 5-6 | Moderate hardness, suitable for most residential flooring | Living room or kitchen tiles that can handle daily wear and tear without breaking a sweat |
| 7-9 | Hard, suitable for high-traffic areas and commercial use | Busy hallways, entryways, or commercial spaces with constant foot traffic |
| 10 | Extremely hard, suitable for industrial use | Industrial workshops or garages where tiles need to withstand heavy use and tough conditions |
Choosing Based on MOHS Hardness
So, how do you pick the right tile for your space? It’s all about matching the hardness to your needs. At Ross’s Discount Home Centre, we’re here to guide you through it.
For areas like bathroom walls or other decorative features, a MOHS rating of 1-2 is just fine. These tiles add a touch of style without needing to withstand heavy wear.
If you’re tiling a room with minimal foot traffic, such as a guest bedroom, a rating of 3-4 will suffice. They’re soft enough to look elegant but durable enough for occasional use.
For most of your home’s flooring needs, especially in high-use areas like the kitchen or living room, aim for tiles with a MOHS rating of 5-6. These tiles perfectly balance beauty and durability.
Busy areas like hallways and commercial spaces need something tougher. Tiles rated 7-9 will stand up to the constant comings and goings without showing wear.
For the most demanding environments, such as industrial settings or workshops, a rating of 10 is recommended. These tiles are virtually indestructible, handling heavy machinery and constant use with ease.
Resistance to Abrasion and Tread Wear
Alright, let’s talk about abrasion resistance—it’s a fancy term for how well your tiles can stand up to everyday wear and tear. Imagine the constant foot traffic in a busy hallway or the rolling wheels of a chair in an office. Abrasion resistance measures a tile’s ability to withstand this kind of wear, whether it’s from people walking over it or mechanical equipment rolling across it. Essentially, it’s the tile’s toughness when it comes to daily use and abuse.
How is Abrasion Resistance Measured?
The ASTM C1027 standard tests the glazed surface of tiles to determine their resistance to abrasion. This involves subjecting the tiles to a series of abrasive actions, simulating the wear caused by foot traffic or mechanical equipment. The tiles are then examined for visible changes, and their performance is categorised into classes.
Here’s how the classification levels break down:
| Class | Suitability | Example |
|---|---|---|
| Class 5 | Heavy Commercial: Suitable for intense commercial and all residential applications. | Heavy-duty tiles, perfect for areas with constant foot traffic and heavy use |
| Class 4 | Commercial: Suitable for medium commercial and all residential applications. | Versatile tiles for both homes and businesses that can handle a fair amount of wear and tear |
| Class 3 | Heavy Residential, Light Commercial: Suitable for all residential applications with average abrasion. | Great for most home spaces and capable of handling light commercial use |
| Class 2 | Residential: Suitable for residential areas excluding kitchens, entryways, and stairs. | Best for places with lighter foot traffic like bedrooms or living rooms |
| Class 1 | Light Residential: Ideal for barefoot traffic and areas without abrasive dirt. | Suitable for spaces like bathrooms or guest rooms where traffic is minimal |
| Class 0 | Wall tile only: Not suitable for floors. | Best for walls where they can look decorative without being exposed to foot traffic |
Choosing Abrasion-Resistant Tiles
When selecting tiles, consider where they’ll be installed and the level of foot traffic they’ll endure. Here are a few tips:
- High-Traffic Areas: For hallways, kitchens, and commercial spaces, aim for Class 4 or 5 tiles. These areas see a lot of action, and you’ll want something that stands up to the challenge.
- Moderate-Traffic Areas: For dining rooms, living rooms, or offices, Class 3 tiles usually suffice. They offer a good balance of durability and aesthetic appeal.
- Low-Traffic Areas: Bedrooms or areas with minimal foot traffic can get away with Class 2 or even Class 1 tiles. These tiles are still durable but are designed for lighter use.
- Wall Applications: Use Class 0 tiles for walls to add a touch of style without worrying about wear and tear.
Tile Breaking Strength (ASTM C648)
A tile’s breaking strength is exactly what it sounds like—the amount of force required to break a tile. Think of it as a tile’s “muscle” rating. This is crucial for areas that will face a lot of impact, like entryways or commercial spaces. You don’t want to install a beautiful tile floor only to have it crack under the weight of a heavy object. This is where the breaking strength rating comes into play.
Understanding Breaking Strength Requirements
- Residential Areas: Generally, residential spaces like living rooms and bathrooms don’t need tiles with super high breaking strength. They just need enough durability to handle regular foot traffic and the occasional dropped object.
- Commercial Areas: These spaces are a different story. Restaurants, shops, and offices need tiles that can handle more wear and tear. They must withstand constant foot traffic, heavy furniture, and occasional impacts. Durability is key.
How to Choose Based on Breaking Strength
When shopping for tiles for sale in Perth, it’s important to match the breaking strength to the environment they’ll be installed in. Here’s a quick guide:
- For Homes: Most residential areas will be just fine with tiles that have a standard breaking strength. For example: Porcelain tiles are strong and durable. With a breaking strength of 250 to 400 pounds, they can handle daily use and the occasional accident with ease.
- For Commercial Spaces: Go for tiles with a breaking strength of over 400 pounds. These tiles are built to endure more rigorous conditions, ensuring your floors remain intact and look good even with heavy use. Higher breaking strength tiles are necessary in commercial settings where they might face constant foot traffic and heavier impacts.
Shade and Appearance Variation (V-Rating)
Let’s talk about V-Ratings for tiles. This rating tells you how much variation in shade and appearance to expect between tiles from the same range. This is different from edge type and tile sizing. Rectified tile edges are machine-cut after firing to create straighter edges and more consistent sizing, which allows for narrower grout joints. The V-Rating helps you understand the visual differences between tiles so you can plan for a balanced, consistent finish across the area.
Understanding the V-Rating Scale
| V-Rating | Variation | Example |
|---|---|---|
| V1 | Uniform appearance, minimal variation. | Ideal when you want a consistent, even look across your entire floor or wall. |
| V2 | Slight variation in colour and texture. | Adds a touch of depth and interest without being too bold, perfect for a subtle yet dynamic appearance. |
| V3 | Moderate variation, with noticeable differences in shade and appearance. | Creates a lively and unique space with a more dynamic, varied appearance. |
| V4 | Substantial variation, each tile may have a unique appearance. | Ideal for those who love a lot of character and individuality in their tiles, creating a one-of-a-kind look. |
How to Use the V-Rating
So, how do you buy tiles with the right V-Rating for your project? It all comes down to your design vision and the vibe you want for your space. Here are some tips to guide you:
- Uniform Spaces: If you’re aiming for a sleek, modern look, V1 tiles are your best bet. They ensure a smooth, consistent finish that’s easy on the eyes.
- Subtle Interest: For spaces where you want a bit of texture without overwhelming variation, go with V2 tiles. They add just enough visual interest to keep things engaging.
- Dynamic Designs: V3 tiles are great for creating a lively, dynamic look. They’re perfect for spaces where you want a bit of drama and uniqueness without going overboard.
- Bold Statements: Want to make a statement? V4 tiles are the ideal choice. Each tile is unique, offering a truly bespoke feel that’s perfect for creative, bold designs.
Chemical Resistance Rating
Last up is a tile’s chemical resistance. Picture this: you’ve just installed your stunning new tile floor, and you’re scrubbing away with your favourite cleaning solution. Over time, if the tiles don’t have good chemical resistance, you might start noticing discolouration, stains, or even damage. Chemical resistance measures a tile’s ability to resist these kinds of damage from chemicals like cleaning agents, acids, and alkalis. Essentially, it’s how well your tiles can stand up to the various substances they might encounter daily.
How is Chemical Resistance Measured?
Let’s look into the specifics of measuring chemical resistance. According to ASTM C650, tiles undergo standardised tests where they are exposed to various chemicals, like acids, alkalis, and cleaning agents, for a specified period. After this chemical assault, the tiles are examined for any visible changes such as staining, discoloration, or surface damage.
The results of these tests are then categorised into levels:
| Class | Effect | Example |
|---|---|---|
| Class A | No visible effect. These tiles are tough, perfect for areas with frequent exposure to harsh chemicals. | Suitable for environments with frequent exposure to harsh chemicals. |
| Class B | Slight effect, but still acceptable for most applications. | These tiles can handle minor chemical exposure but might show minor wear over time. |
| Class C | Noticeable effect, not recommended for areas with chemical exposure. | Best kept away from environments with harsh chemical exposure. |
| Class D | More noticeable effects, significantly impacted by chemical exposure. | Not suitable for areas with moderate to high chemical exposure. |
| Class E | Highly affected by chemicals and not suitable for environments with chemical exposure. | Should be avoided in any environment where chemical exposure is a concern. |
Choosing Chemical-Resistant Tiles
So, how do you go about buying tiles for sale in Perth with high chemical resistance? Here are a few tips:
- Kitchens: For kitchen floors and countertops, look for tiles that specifically mention high chemical resistance. Porcelain tiles are often a solid choice here due to their dense and non-porous nature, making them less likely to absorb harmful substances.
- Commercial Spaces: If you’re outfitting a commercial kitchen, lab, or any area where strong chemicals are used regularly, prioritise tiles with the highest chemical resistance ratings. These tiles are designed to withstand more intense exposure to chemicals, ensuring they remain intact and looking good despite diligent cleaning routines.
- Bathrooms and Laundry Rooms: Don’t forget about these areas either! They may not face the same chemical exposure as kitchens or commercial spaces. However, choosing tiles with good chemical resistance is still important. This helps them handle the cleaning products used to keep these areas clean.
Conclusion
In this guide, we’ve explored the essential tile ratings and grades—from the PEI rating of abrasion resistance to the V-Rating for shade and appearance variation. Each rating plays a crucial role in helping you buy the perfect tile for your specific application, whether it’s for a bustling commercial space or a cosy residential nook. Understanding these ratings ensures you buy tiles in Perth that not only look fantastic but also stand up to the demands of their environment.
