JC/T 412.2-2006 in English

Scope

This part of JC/T 412 specifies the classification, specifications, grades and markings, raw materials, requirements, test methods, inspection rules, markings and certificates, transportation and storage of chrysotile asbestos fiber cement slabs (referred to as "asbestos slabs"). This section applies to chrysotile fibers alone (or mixed with organic synthetic fibers or cellulose fibers) as reinforcing materials, based on cement or cement mixed with siliceous and calcareous materials, through pulping, molding, autoclaving (or steam) cured asbestos-free fiber cement lithography. After subsequent surface treatment of products produced according to the standards of this part, the physical and mechanical properties of decorative boards can comply with this standard. However, the aging resistance of the treated product is determined by the quality of the coating. The quality and inspection methods of the coating are not included in this section.
