Understanding AC ratings on laminate flooring
AC1 to AC5 — what each rating actually means in real-world wear, and which rating fits your space.
AC ratings are the most useful single number on any laminate datasheet, and the most commonly misread. The scale runs from AC1 through AC6 and measures abrasion resistance and impact tolerance through a sequence of controlled tests under EN 13329. Understanding the scale lets a specifier match the laminate to the room — and prevents both expensive over-specification and risky under-specification.
This article explains what each AC level means in practice, where each one belongs, and how to read the rating alongside the other figures on a laminate datasheet. The number is meaningful only in the context of the full specification.
The AC scale, in plain language
AC1 covers light residential use — a bedroom, a study, a quiet space with low traffic and few hard chair impacts. AC2 covers moderate residential use — living rooms in smaller households. AC3 covers heavy residential and light commercial use, the most commonly specified level for whole-house laminate installations.
AC4 covers moderate commercial — boutique retail, mid-traffic offices, professional consulting suites. AC5 covers heavy commercial — hospitality back-of-house, education circulation, public retail. AC6 is rarely seen in Australia and is reserved for the most demanding commercial floors.
How the test actually works
The Taber abrasion test rotates a weighted abrasive wheel against a laminate sample and counts the number of revolutions before two thresholds are reached: the initial point where the wear layer breaks through, and the average point of complete decor loss. The two values are combined to give the AC rating. Companion tests under EN 13329 cover impact resistance, residual indentation, and resistance to cigarette burns and stains.
The test is destructive and repeatable, which is what makes the AC scale useful — a number from one lab is comparable to a number from another. It is not a perfect predictor of real-world wear, but it is the closest the category has.
Matching the rating to the room
For a private residence with a young family and a dog, AC4 is generous and AC3 is honest. For a rental property, AC4 buys an extra tenancy cycle without much premium. For a boutique office or consulting suite, AC4 is the right starting point; for retail or hospitality, AC5 is the appropriate spec. Our laminate range publishes the AC rating for every decor.
Our commercial laminate guide covers the moderate-commercial and heavy-commercial decisions in more detail, particularly the slip-rating and acoustic considerations that travel alongside the AC question.
Reading the AC rating alongside other figures
The AC rating is the headline number, but it should not be read alone. The wear layer thickness, the locking system type, the warranty schedule, the acoustic underlay specification, and the moisture tolerance all matter. A laminate with AC5 abrasion but no moisture tolerance will still fail in a kitchen; a laminate with AC4 and a strong locking system will outperform AC5 with a weaker join.
The other rating to look for is the EN 13329 class — the underlying European standard the AC scale derives from. Class 21 through 23 cover residential; Class 31 through 33 cover commercial. A laminate datasheet that publishes the class as well as the AC rating is being transparent about its testing.
How our range positions
Our laminate range is positioned in the AC4 to AC5 band, with the moderate-commercial decors at AC4 and the heavy-commercial decors at AC5. This means even our residential customers are buying a floor rated for commercial use — overhead that turns into longevity in normal home conditions.
For wider context on the AC scale, the Australian Resilient Flooring Association publishes accessible category guidance, and the Standards Australia catalogue includes the relevant European-standard references for the underlying test methodology. The category comparison article covers when laminate is the right answer in the first place.
Reading AC ratings on imported decors
Most laminate sold in Australia is imported and tested under European standards. An imported laminate quoting AC4 should have an EN 13329 class number that maps to AC4 — that is the cross-check that confirms the rating is current and the testing is in date. Where a manufacturer publishes an AC rating without the underlying EN class, ask for the test certificate. Our test reports section publishes the certificates for every AC level in our range, and the contact page reaches the studio team for project-specific evidence requirements.
