标准摘要
[中文适用范围]： 本部分ISO 18672规定了由聚酯树脂混凝土（PRC）制成的管道、管件、接头、材料、试验方法和标记的定义、要求和特性，适用于在无压运行的排水或污水系统中使用的产品。它适用于采用开沟技术或顶管技术安装的埋地安装产品。它适用于公称尺寸从DN 150到DN 3000的圆形截面、从WN/HN 300/450到WN/HN 1400/2100的蛋形截面以及从DN 800到DN 1800的 kite形截面的管道、管件及其接头。这些产品的预期用途是在温度高达50°C的情况下输送污水、雨水和地表水，无压或偶尔承受高达0.5 bar的压力，并安装在受车辆和/或行人交通影响的区域。管道根据预期的安装方法和横截面形状进行分类。注：选择适当的产品是采购方或规格制定者的责任，需考虑特定要求以及任何相关的国家法规和安装实践或规范。 [外文原描述]： ISO 18672-1:2009 specifies definitions, requirements and characteristics of pipes, fittings, joints, materials, test methods and marking for pipes and fittings made from polyester resin concrete (PRC), intended to be used within a drain or sewer system operating without pressure. It applies to products for use in buried installations to be installed by open-trench techniques or pipe jacking. It applies to pipes, fittings and their joints of nominal sizes from DN 150 to DN 3000 for circular cross-sections, from WN/HN 300/450 to WN/HN 1400/2100 for egg-shaped cross-sections and from DN 800 to DN 1800 for kite-shaped cross-sections.
