《GB/T 15345-2003混凝土输水管试验方法》由TC197（全国水泥制品标准化技术委员会）归口，主管部门为中国建筑材料联合会。
本标准规定了混凝土输水管外观质量、几何尺寸、水压试验、保护层厚度、混凝土强度、保护层砂浆强层和保护层砂浆吸水性、相对转角等项目的试验方法，适用于自应力混凝土输水管，用震动挤压工艺、管芯缠丝工艺生产的预应力混凝土输水管及预应力钢筒混凝土管等四种混凝土输水管。

Scope

This standard specifies the test methods for concrete water pipe appearance quality, geometric dimensions, hydraulic test, protective layer thickness, concrete strength, protective layer mortar strength, water absorption of protective layer mortar, and relative rotation angle. This standard is applicable to self-stressed concrete water pipes (indicated by Z or Z (I), Z (II) and Z (III) below); There are four kinds of concrete water pipes, including YYG and SYG below) and prestressed steel cylinder concrete pipes (PCCP or PCCPL, PCCPE below).
