NF ISO 800

1.1 This part of ISO 14526 establishes a data block system for the designation of phenolic powder moulding compounds (PF-PMCs). 1.2 The various types of PF-PMC are differentiated from each other by a classification system based on information about the filler/reinforcement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purposes (designatory properties). 1.3 This part of ISO 14526 is applicable to all PF-PMCs ready for normal use in the form of powder, granules or ground material. 1.4 It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 14526 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 14526-2, if suitable. 1.5 Whenever general requirement data, as covered by ISO 14526-3, need to be indicated, this is also done using this data block system. 1.6 To ensure that code-letters and code-numbers remain unambiguous, and to avoid conflicts within the system, any new code-letters or code-numbers for use in data block 1, 2 or 3 shall be approved before use by the secretariats of ISO/TC 61/SC 1, SC 12 and SC 13.

This part of ISO 14526 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of phenolic powder moulding compounds (PF-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. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, PMCs are also included in this part of ISO 14526, as are the designatory properties found in ISO 14526-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

This part of ISO 14526 specifies the requirements for the physical and chemical properties of phenolic powder moulding compounds (PF-PMCs) and compression- or injection-moulded test specimens produced from them. It is limited to those powder moulding compounds whose composition and properties are significantly different. It is further limited to those moulding compounds which are of general technical and/or economic importance. The properties which are used to characterize the moulding compounds, the test methods and the test conditions are selected from those given in ISO 14526-2. The moulding compounds are divided into types according to their composition and properties. The various types are designated using the designation system defined in ISO 14526-1.
