Understanding Heavy Duty Commercial Wear for Carpet Tiles
When selecting carpet tiles for commercial use, understanding the classification and testing criteria is crucial to ensure durability and performance. The EN 1307:2014 standard provides a comprehensive framework for evaluating and classifying textile floor coverings, including carpet tiles, based on their suitability for different levels of use. Here’s an in-depth look at what “Heavy Duty Commercial Wear” means and the requirements for a Class 33 rating.
What is Heavy Duty Commercial Wear?
Heavy Duty Commercial Wear for carpet tiles indicates that the product is engineered to withstand substantial foot traffic and stress in commercial environments. This makes it suitable for high-traffic areas such as:
Carpet tiles classified under this category are designed to maintain their appearance and functionality even in the most demanding settings.
Class 33 Certification
Class 33 is the highest classification for commercial use under the EN 1307:2014 standard. This certification ensures that carpet tiles are appropriate for areas with very high traffic. To achieve Class 33, carpet tiles must pass rigorous testing to assess various performance characteristics:
-
- Wear Resistance: The ability of the carpet tile to resist wear over time, typically evaluated using tests like the Martindale or Hexapod Tumbler test.
-
- Appearance Retention: The carpet’s capacity to maintain its appearance despite heavy use, assessed through the Vetterman Drum test.
-
- Static Loading: Measures how well the carpet can recover from static loads, such as heavy furniture, ensuring it does not permanently compress.
-
- Dimensional Stability: Ensures that the carpet tiles retain their shape and size under varying environmental conditions, preventing issues like curling and edge damage.
-
- Fire Safety: Includes flammability and smoke emission tests to comply with safety standards for commercial buildings.
-
- Additional Performance Properties: These include colour fastness, castor chair suitability, suitability for use on stairs, electrical properties, thermal resistance, and fraying behaviour.
Key Specifications for Carpet Tiles
Beyond the basic ratings, several specifications influence the performance and longevity of carpet tiles:
-
- Fibre Type: Common fibres include nylon, polyester, and polypropylene. Nylon is highly durable and resilient, making it ideal for high-traffic areas. Polyester offers good stain resistance, while polypropylene is cost-effective and moisture-resistant. Eco-friendly options like Econyl, used in products such as Duraflor’s Cubism, are gaining popularity for their sustainability.
-
- Pile Height and Density: Higher density and appropriate pile height enhance the carpet’s durability and comfort. These factors are crucial for balancing wear resistance and user comfort.
-
- Backing Material: The backing provides stability and support. Bitumen backed tiles for example provide durability, stability, help with acoustics and are more resistant to moisture and humidity compared to other backing materials. This resistance makes them suitable for environments where there may be occasional spills or higher humidity levels, such as in kitchens or near entrances.
-
- Environmental Considerations: Eco-friendly carpet tiles made from recycled materials or with low VOC emissions contribute to healthier indoor air quality and sustainability.
Conclusion
By selecting carpet tiles that meet these stringent standards, you can ensure the flooring will endure heavy use while maintaining its appearance and functionality.
