BS ISO 9349:2004规定了适用于预绝缘球墨铸铁的要求和试验方法 管道（或其部件）施工用管道、配件、附件及其接头:输送水（如饮用水）、废水和其他液体；有压力或无压力操作；安装在地下或地上；限制输送流体的温度变化。这些管道主要用于防止 通过提供外部绝缘将水从冰冻中输送出来。注1:在本文件中，所有压力均为相对压力，单位为巴1）。除了现有国际标准的规范外，本文件还提供了 输送球墨铸铁管和配件，材料规范，尺寸和公差， 预保温隔热层和外壳的机械和热性能 球墨铸铁管、配件和附件。交叉引用:ISO 527-2ISO 844ISO 845ISO 1183-3ISO 2531ISO 6892-1ISO 7186ISO 8497ISO/TR 25901-3购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS ISO 9349:2004 specifies the requirements and test methods applicable to preinsulated ductile iron pipes, fittings, accessories and their joints for the construction of pipelines (or parts thereof):to convey water (e.g. potable water), wastewater and other liquids;to be operated with or without pressure;to be installed below or above ground;to limit temperature variations of the conveyed fluids. These pipelines are mainly used to prevent the water to be conveyed from freezing by providing external insulation.NOTE 1 In this document, all pressures are relative pressures expressed in bars1).This document gives, in addition to the specifications of the existing International Standards for the conveying ductile iron pipes and fittings, specifications for materials, dimensions and tolerances, mechanical and thermal properties of the thermal insulation layer and external casing of preinsulated ductile iron pipes, fittings and accessories.Cross References:ISO 527-2ISO 844ISO 845ISO 1183-3ISO 2531ISO 6892-1ISO 7186ISO 8497ISO/TR 25901-3All current amendments available at time of purchase are included with the purchase of this document.
