T/YSX 002-2023 Natural stone mosaic
Basic Information
Scope
Scope: This document specifies the classification, material requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of natural stone mosaic products. This document is applicable to natural stone mosaic products used in building decoration. Main technical content: In terms of inspection items, on the basis of the industry standard JC/T 2121, we selected representative items such as appearance quality, specification size, water absorption, adhesion of backing, grid area, and radioactivity, which not only meet the use requirements of natural stone mosaic products but also promote the improvement of the quality of stone mosaic products. During the preparation and development process, firstly, we clearly described the detection items defined in JC/T 2121 that were relatively vague, making them more convenient for detection and use; secondly, we improved some detection indicators, making the group standard more practical and advanced; thirdly, we improved the method of adhesion of backing, making the method more operable.
