Plastics — Unsaturated-polyester powder moulding compounds (UP-PMCs) — Part 1: Designation system and basis for specifications

1.1 This part of ISO 14530 establishes a data block system for the designation of unsaturated-polyester powder

moulding compounds (UP-PMCs).

1.2 The various types of UP-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 14530 is applicable to all UP-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 14530 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 14530-2, if suitable.

1.5 Whenever general requirement data, as covered by ISO 14530-3, 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.
