AC (Abrasion Class) hardness ratings are a standardized measure adopted by The Association of European Producers of Laminate Flooring (ELPF) . The AC measure rates abrasion resistance. All laminated flooring produced by Richwood laminate flooring manufacturer has a minimum punishment class of 23 for residential use (heavy) and 31 for commercial use (moderate), or an AC3 rating. AC ratings 4 and 5 are equally suitable for residential use as AC3 but somewhat more suitable for high traffic commercial applications. AC ratings below 3 are recommended for low traffic residential use only. Here is a more detailed guide:
AC1 is suitable for lighter, more infrequent traffic, e.g. a bedroom.
AC2 is suitable for general residential use in living rooms and dining rooms.
AC3 can be applied to more varied locations, such as small offices and other light commercial location
AC4 can be installed in higher traffic commercial areas such as boutiques, busier offices, and restaurant
AC5 is more durable still and can withstand the traffic of heavier commercial areas such as department stores and public buildings.
