What is AC Rating for Flooring?
AC rating (Abrasion Class) is the European standard (EN 13329) for measuring the surface durability of laminate and SPC flooring. It tests abrasion resistance (wear), impact resistance, staining, burning cigarettes, and furniture leg resistance in a single combined test. Higher AC number = harder, more durable surface.
AC Rating Scale
| Rating | Category | Use Case | Indian Equivalent |
|---|---|---|---|
| AC1 | Moderate residential | Bedrooms, spare rooms | Rarely sold in India |
| AC2 | General residential | Living rooms, bedrooms | Budget segment |
| AC3 | Heavy residential / light commercial | All residential rooms | Good quality residential standard |
| AC4 | General commercial | Offices, retail, restaurants | Premium residential / standard commercial |
| AC5 | Heavy commercial | Airports, supermarkets, hospitals | High-traffic commercial / luxury residential |
| AC6 | Very heavy commercial | Industrial applications | Rarely specified in India |
Which AC Rating for Indian Homes?
Bedroom: AC3 minimum, AC4 recommended
Bedrooms see light traffic but are used daily. AC3 is technically sufficient but choosing AC4 costs only marginally more and provides peace of mind for 20+ year durability. Always choose AC4 for children's bedrooms where impact resistance matters.
Living Room / Hall: AC4 mandatory
Indian living rooms double as social and family spaces with regular footwear traffic. AC4 is the minimum for living rooms — do not compromise on this in the name of cost saving. AC5 if the living room leads directly to the entrance.
Kitchen: AC4 or AC5 (or SPC)
Indian kitchens are AC4-AC5 environments. For wood-look flooring in Indian kitchens, use AC4 waterproof laminate (with waterproof core) or AC4 SPC. For dry European-style kitchens, AC5 laminate works.
Commercial (Office, Retail): AC4 or AC5
Office corridors and reception areas: AC4. Retail floors with continuous footfall: AC5. Hospital corridors and airports: AC5 (specify vinyl SPC not laminate for wet-zone commercial applications).
Wear Layer vs AC Rating for SPC
SPC and LVP use wear layer thickness rather than AC ratings as the primary durability measure, though many SPC products are also assigned AC equivalents. As a guide: 0.2mm wear = AC2 equivalent; 0.3mm = AC3; 0.5mm = AC4; 0.7mm = AC5. Always specify wear layer thickness in mm for SPC — not just the AC equivalent.
Why AC Rating Matters More Than Brand in India
In the Indian market, many flooring products are sold without clear AC rating disclosure. Insist on the EN 13329 test certificate from the manufacturer — not just a dealer's verbal claim of "AC4". The certificate should list the specific test results for each parameter (abrasion, impact, staining, burning cigarette, chair caster) separately.
