5、between the corresponding colour reference sample held by the supplier and the specimen under test. 5.2 Surface finish matching When inspected at different viewing angles, there shall be no significant difference between the corresponding surface-finish reference sample held by the supplier and the
6、specimen under test. For critical colour-matching applications, it is recommended that solid surfacing materials (SSM) be checked for colour/surface-finish compatibility before fabrication or installation. 5.3 Thickness No requirements for nominal thickness are specified for individual types of soli
