标准摘要
[中文适用范围]： 本文件规定了压力和非压力应用中输送流体的公制热塑性塑料管道的标称外径。 它还规定了压力应用的标称压力等级和最低所需强度。 它适用于沿管道整个长度具有恒定圆形横截面的光滑热塑性塑料管道，无论其制造方法或结构材料如何。 不适用于按公称内径DN/ID指定的管道。 本文件是标准制定者在起草产品标准时选择公称直径和公称压力的依据。 [外文原描述]： ISO 161-1:2018 specifies the nominal outside diameters for metric thermoplastics pipes for the conveyance of fluids in pressure and non-pressure applications. It also specifies nominal pressure ratings and minimum required strengths for pressure applications. ISO 161-1:2018 is applicable to smooth thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever their method of manufacture or material of construction. ISO 161-1:2018 is not applicable to pipes designated according to the nominal inside diameter DN/ID. ISO 161-1:2018 is a basis for standards writers for the selection of nominal diameters and nominal pressures in the drafting of product standards.
