标准范围

ISO 17484-1:2006规定了基于拟用于建筑物内供气的管道、配件及其接头的多层管道系统的一般要求和性能要求。ISO 17484-1:2006还涵盖了由一个应力设计层、粘合剂和阻挡层组成的PE-X和PE管。ISO 17484-1:2006给出了由基于热塑性塑料的多层管道组成的管道系统的设计指南，其中至少60%的壁厚是聚合物材料。用于应力设计层和所有内层的聚合物材料要求为聚乙烯（PE）和/或交联聚乙烯（PE-X）。金属多层膜的外层要求为PE或PE-X。PE-RT被视为PE，但具有特定的环向应力性能。ISO 17484-1:2006适用于在-20°C至60°C温度下运行的系统。在ISO 17484-1:2006中，交联聚乙烯（PE-X）和粘合层被视为热塑性材料。对于大于63 mm的尺寸，还必须满足ISO 18225的要求。ISO 17484-1:2006适用于建筑物中使用的管道系统，以供应最大工作压力不超过500 kPa（5 bar）的气体。ISO 17484-1:2006适用于D类气体燃料、天然气和E类气体燃料、液化石油气蒸汽以及天然气或液化石油气蒸汽。

ISO 17484-1:2006 specifies the general requirements and the performance requirements for multilayer pipe systems based on pipes, fittings and their joints intended to be used for gas supply within buildings.PE-X and PE pipes composed of one stress-designed layer, adhesive and a barrier layer are also covered by ISO 17484-1:2006.ISO 17484-1:2006 gives guidance for the design of piping systems consisting of multilayer pipes based on thermoplastics, for which at least 60 % of the wall thickness is polymeric material. Polymeric materials intended for stress-designed layers and all inner layers are required to be polyethylene (PE) and/or crosslinked polyethylene (PE-X). The outer layer of a metal multilayer is required to be PE or PE-X. PE-RT is considered as PE but with specific properties concerning hoop-stress performance.ISO 17484-1:2006 applies to systems that operate at temperatures of - 20 °C up to 60 °C.For the purpose of ISO 17484-1:2006, crosslinked polyethylene (PE-X) and adhesive layers are considered as thermoplastic materials.For sizes greater than 63 mm the requirements of ISO 18225 have to be fulfilled in addition.ISO 17484-1:2006 is applicable for piping systems used in buildings to supply gas with a maximum operating pressure up to and including 500 kPa (5 bar).ISO 17484-1:2006 applies to Category D gaseous fuel, natural gas, and Category E gaseous fuel, LPG vapour, and natural gas or LPG vapour.
