摘　　要：分析了中美及ISO(欧洲)塑料压力管道标准体系及定级要求的差异,其中国标(GB)标准体系与欧洲(ISO)标准体系要求一致,与美国(ASTM)标准体系有一定区别,但其聚合物管道长期性能评价的原理一致。分别介绍了ASTM D2837、ISO 9080和GB 182525等标准提出的PVC-C管道的压力设计基础以及管材混配料的定级曲线,阐明了依据GB/T 39380.1—2021如何判定喷水灭火用PVC-C管道混配料的定级曲线是否合格。通过对国内外氯化聚氯乙烯(PVC-C)消防管材标准进行了对比,结果标明,国标与美标规格尺寸、管材壁厚等性能要求上基本一致;我国GB/T39380要求的管道系统可以保证在我国的消防压力设计条件下(20℃)50年的安全使用期。This paper analyzed the differences between the standard systems and grading requirements of plastic pressure pipes in China(GB),America(ASTM)and Europe(ISO).The GB standard system of China has the same requirements with ISO(Europe)standard system,but there are some differences with the ASTM standard system of America.However,the principle of long-term performance evaluation of polymer pipes is the same for three parts.This paper introduced the pressure design basis of PVC-pipe and grading curve of mixed materials of the pipes according to the ASTM D2837,ISO 9080,and GB 182525 standards.According to the GB/T 39380.1—2021 standard,the determination of qualification for the grading curve of PVC-C pipe mixture for fire sprinkling was clarified.The standards of PVC-C fire pipe at home and abroad were compared.The specifications,dimensions,pipe wall thickness,and other performance requirements were almost same for the Chinese national and American standards.The piping system in accordance with the national standard GB/T 39380 can guarantee the safe use at 20 oC for 50 years under the fire pressure design conditions in China.
