标准范围

ISO 9988-2:2006规定了试样的制备方法以及用于测定聚甲醛模塑和挤出材料性能的试验方法。给出了处理试验材料以及在模塑前对试验材料和试验前试样进行调节的要求。描述了制备试样的程序和条件，并给出了测量制备试样材料性能的程序。列出了表征聚甲醛模塑和挤出材料的合适和必要的性能和测试方法。这些特性选自ISO 10350-1:1998中的一般试验方法。ISO 9988-2:2006中还包括了这些模塑和挤压材料广泛使用或特别重要的其他测试方法，作为ISO 9988-1中规定的指定特性:熔体流动速率和拉伸模量。

ISO 9988-2:2006 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyoxymethylene moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given.Procedures and conditions are described for the preparation of test specimens, and procedures are given for measuring properties of the materials from which these specimens are made. Properties and test methods which are suitable and necessary to characterize polyoxymethylene moulding and extrusion materials are listed.The properties have been selected from the general test methods in ISO 10350-1:1998. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in ISO 9988-2:2006 as designatory properties specified in ISO 9988-1: melt flow rate and tensile modulus.
