DIN EN ISO 14527-2-2000 塑料.脲醛和脲/蜜胺酚醛粉末模塑化合物(UF-和UF/MF-PMCs).第2部分:试样的制备和特性的测定
Plastics - Urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs) - Part 2: Preparation of test specimens and determination of properties (ISO 14527-2:1999); German version EN ISO 14527-2:1999
The document specifies the methods of preparation of test specimens and the test methods to be used in determining 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 before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PMCs are listed.
