本国际标准规定了通过注射成型生产管状试样的一般程序用于测定抗内压性的试件。它还规定了要安装的模具的设计习惯于通过使用与注射成型管道组件（如管件）相同的材料，这些试件可以可以确定配件材料在静水压力和压力下的时间相关行为与挤压管道的规定条件完全相同。可以测试发动机的内部压力阻力根据ISO 1167的注塑管状试样，根据ISO 9080中规定的方法，以确定MRS，并对材料进行分类符合ISO 12162。管状试件还可以验证先前确定的应力/时间上的各个点作为最低材料试验要求的回归曲线。本国际标准建立的基础允许重复制备试样。然而，给出的方法是一种通用方法，必须指定注射成型参数使用的每种材料。注:如果用于管道部件注射成型的化合物也可以挤出，则其时间相关可使用注射成型或挤压管状试件来研究性能。
This International Standard specifies a general procedure for the production, by injection-moulding, of tubular testpieces for the determination of the resistance to internal pressure. It also specifies the design of the mould to beused.By using the same material as for injection-moulded piping components, such as fittings, these test pieces make itpossible to determine the time-related behaviour of the fitting material under hydrostatic pressure and under thevery same conditions as specified for extruded pipes. It is possible to test the resistance to internal pressure of theinjection-moulded tubular test pieces in accordance with ISO 1167, to extrapolate the results in accordance with amethod such as that specified in ISO 9080 in order to determine the MRS, and to classify the material inaccordance with ISO 12162.The tubular test pieces also make it possible to verify individual points on previously established stress/timeregression curves as a minimum material test requirement.The basis established by this International Standard allows test pieces to be prepared reproducibly.Nevertheless, the method given is a general one, and the injection-moulding parameters have to be specified forevery material used.NOTE If the compound used for the injection-moulding of piping components can also be extruded, then its time-relatedbehaviour may be investigated using either injection-moulded or extruded tubular test pieces.
