Plastics — Urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs) — Part 1: Designation system and basis for specifications
urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs).
1.2 The various types of UF- and UF/MF-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 14527 is applicable to all UF- and UF/MF-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 14527 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 14527-2, if suitable.
1.5 Whenever general requirement data, as covered by ISO 14527-3, 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.
