Significance and Use
This standard may be used by paint companies and raw material suppliers to assess effectiveness of interior architectural primers for blocking stains from bleeding through to a topcoat.
In practice, different ink-stained substrates may give various results for stainblocking performance for a primer and topcoat system. As such, this test method may be used for a number of different ink-stained surfaces.
1. Scope
1.1 This standard provides a method for evaluating the ability of an architectural paint system to block ink stains from markers and writing instruments from bleeding through a primer into a topcoat.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
