1.适用范围本标准规定了作为建筑物开口结构材料使用的硬质聚氯乙烯挤出成型的主要型材(以下称型材)。注[1]:JISA0005(建筑物开口部结构材料标准模数公称尺寸)规定的1种开口部结构材料和2种开口部结构材料。注[2]:以 JISK6740(硬质聚氯乙烯混合料)规定的硬质聚氯乙烯树脂为主体,混合料尤其重视冲击性和耐候性。
1. Scope of application This standard specifies the main profiles (hereinafter referred to as profiles) of rigid polyvinyl chloride extruded as structural material for building openings. Note [1]: One kind of opening structural material and two kinds of opening structural material specified by JISA0005 (standard structural module nominal size of building opening structural material). Note [2]: The rigid polyvinyl chloride resin specified in JIS K6740 (rigid polyvinyl chloride compound) is mainly used as the main component, and the mixture is particularly important for impact resistance and weather resistance.
