Over deze norm
1.1 This practice covers a basic method for evaluating the performance of anti-graffiti products on mineral building substrates by a series of increasingly abrasive cleaning methods. The anti-graffiti materials are applied to a series of concrete, masonry and natural stone specimens for evaluation. Graffiti resistance is based on how a defined set of markings are removed by a designated set of cleaning techniques.
1.2 This practice also defines a procedure to evaluate graffiti removal after re-marking with subsequent re-cleaning. It does not address the re-treatment of substrates after a material is no longer graffiti resistant.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
