For the purpose of this standard, fibre-cement slates have been classified according to their bending moment. This document covers fibre-cement slates reinforced with fibres of different
42、 types as specified in 5.1.1. This standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed products. 2 Normative references The following referenced documents are indispensable for the application of thi
