Dentistry. Materials used for dental equipment surfaces. Determination of resistance to chemical disinfectantsBS EN ISO 21530: 2004 specifies test methods for determining the resistance to chemical disinfectants of all materials used for external surfaces of dental equipment intended for such disinfection. Three test methods are specified: an immersion test, a spray test and a contact test. The choice of test method to be used is left to the discretion of the party conducting the testing. This international standard does not address the bactericidal,
