ISO 14528-1:1999

Plastics — Melamine-formaldehyde powder moulding compounds (MF-PMCs) — Part 1: Designation system and basis for specifications

Scope

1.1 This part of ISO 14528 establishes a data block system for the designation of melamine-formaldehyde
powder moulding compounds (MF-PMCs).
1.2 The various types of 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 14528 is applicable to all 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 14528 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 14528-2, if suitable.
1.5 Whenever general requirement data, as covered by ISO 14528-3, 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.
