标准范围

ISO 14527的本部分规定了试样的制备方法和试验中使用的试验方法脲醛和脲/三聚氰胺-甲醛粉末模塑化合物性能的测定（UF-和UF/MF PMCs）。处理试验材料的要求以及试验前对试验材料的调节要求此处给出了试验前的成型和试样。试样制备程序和条件以及试样性能测量程序给出了制作这些试样的材料。适用的性能和测试方法，以及列出了表征PMC的必要条件。这些性能是从ISO 10350中的通用测试方法中选择的-1.其他广泛使用的试验方法对于PMC，或对PMC有特殊意义的PMC，也包括在ISO 14527的本部分中，以及指定的PMC特性见ISO 14527-1。为了获得可重复性和可比性试验结果，有必要使用制备和测试方法调节、试样尺寸和本文规定的试验程序。确定的值不会必须与使用不同尺寸的试样或使用不同材料制备的试样相同程序。

This part of ISO 14527 specifies the methods of preparation of test specimens and the test methods to be used indetermining the properties of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds(UF- and UF/MF-PMCs). Requirements for handling test material and for conditioning both the test material beforemoulding and the specimens before testing are given here.Procedures and conditions for the preparation of test specimens and procedures for measuring properties of thematerials from which these specimens are made are given. Properties and test methods which are suitable andnecessary to characterize PMCs are listed.The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide usefor, or of particular significance to, PMCs are also included in this part of ISO 14527, as are the designatoryproperties found in ISO 14527-1.In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation andconditioning, the specimen dimensions and the test procedures specified herein. Values determined will notnecessarily be identical to those obtained using specimens of different dimensions or prepared using differentprocedures.
