摘　　要：我国塑料压力管的产品标准与国际标准及欧洲标准一致,但是设计规范则不同。塑料管的短期强度和长期强度相差较大,因此分别检验长期负载小于长期强度和短期负载小于短期强度会更加合理。若过分保守,则一定程度上不利于经济效益和环境保护。Product standards of plastics pressure pipe in China are according to ISO standards and EN standards, but design codes of them are different.The long term strength and short term strength of plastics pipe are quite different.The short term strength and long term strength should be checked separately.Conformism will make against benefit of economy and environment protection.
