Abrasion testing can be used to measure and predict overall durability of the material as it may perform in real world applications. This test method measures the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. The result can be reported as a relative volume loss or an abrasion resistance

Quantitative suspension tests (to EN 1276 and EN 1650, or EN 13727 and EN 13624) are used for efficacy tests too, excluding products for veterinary use. In addition to suspension tests, efficacy is also tested with simulated laboratory testing, using surface tests such EN 13697 for bactericidal, fungicidal and yeasticidal on non-porous surfaces.
