What is an AC Rating?

Flooring Laminate Sisu Technical

When choosing laminate flooring, the Abrasion Class (AC) rating is an important aspect to consider. It is a wear rating given to indoor flooring and measures its resistance to abrasion, impact, and stains. Various tests are executed to determine how durable flooring is and if the product fails just one test it will be disqualified and may not be sold to the public.

How many AC ratings are there?

AC ratings are broken down into five levels ranging from AC1, moderate residential use, to AC 6, intensive commercial use. As seen below, the ratings are divided into two applications: residential and commercial. Levels AC1 to AC3 are appropriate for residential areas, while AC4 and AC6 are suitable for commercial use. These applications are then broken down into traffic intensity levels from moderate to heavy traffic. While AC6 is the highest recognised abrasion criteria rating, it is rare and only necessary for extremely high-wear public areas. For busy shops, showrooms and offices a laminate floor with an AC5 rating should be sufficient.  

The following table shows the AC rating and their suitable uses:

What tests are done to determine the AC rating?

To determine the AC rating of a laminate plank, the flooring goes through a rigorous test using the Taber Rotary Platform Abraser. The test measures the number of wear cycles completed until initial damage to the decorative layer is observed. As the total number of Taber wear cycles increases, so does the product’s durability and its wear layer. It is important to note that this test does not take abnormal wear and tear, such as spike heel shoes or insufficient protection from furniture, into consideration.

It is therefore important to still regularly clean your flooring and use floor protectors on your furniture to enhance the durability of your laminate flooring. We also recommend that you read our laminate installation guide for further maintenance tips and tricks.

What are the AC ratings EnviroBuild offers?
