Full title and description

St ISO 14530-3-1999 — Plastics — Unsaturated‑polyester powder moulding compounds (UP‑PMCs) — Part 3: Requirements for selected moulding compounds. This product designation is the ISO international standard that defines general requirement data for selected unsaturated‑polyester powder moulding compounds; the prefix "St" (as seen in some catalogs) is an alternative/national listing style used in some databases.

Abstract

This part of ISO 14530 specifies the requirements for the physical and chemical properties of unsaturated‑polyester powder moulding compounds (UP‑PMCs) and for compression‑ or injection‑moulded test specimens produced from them. It is limited to selected powder moulding compounds of significant technical or economic importance, and uses properties, test methods and conditions selected from ISO 14530‑2; types are designated according to ISO 14530‑1.

General information

• Status: Published (International Standard; confirmed in periodic reviews).
• Publication date: 18 November 1999.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 83.080.10 — Thermosetting materials (UP‑PMC materials).
• Edition / version: Edition 1 (1999).
• Number of pages: 4 (ISO published PDF).

Scope

The standard defines requirement data for selected unsaturated‑polyester powder moulding compounds (UP‑PMCs). It applies only to powder moulding compounds whose composition and properties differ significantly and to those of general technical/economic importance. The characterization properties, test methods and test conditions referenced in this part are taken from ISO 14530‑2; material type designations follow the system in ISO 14530‑1.

Key topics and requirements

• Designation and classification of UP‑PMCs according to the system in ISO 14530‑1.
• Specified requirement data (physical and chemical) for selected UP‑PMCs of general technical/economic importance.
• Reference to test methods and specimen preparation given in ISO 14530‑2 for determining the stated properties.
• Limitation to moulding compounds whose composition/properties are significantly different (not all UP‑PMCs are covered).
• Use of the listed properties and conditions to allow reproducible comparative data for specification and procurement.

These points are drawn from the part‑3 scope and cross‑references to parts 1 and 2 of ISO 14530.

Typical use and users

Used by material manufacturers and formulators, product engineers, quality and testing laboratories, and procurement/specification authors to specify, compare and accept unsaturated‑polyester powder moulding compounds for thermoset powder moulding applications. Also used by national standards bodies when adopting the ISO text as a national or regional standard.

FAQ

Q: What is this standard?

A: ISO 14530‑3:1999 is the International Standard that specifies requirement data for selected unsaturated‑polyester powder moulding compounds (UP‑PMCs).

Q: What does it cover?

A: It covers the required physical and chemical properties and the designation of selected UP‑PMCs; test methods and specimen preparation referenced are those from ISO 14530‑2. The part is limited to selected compounds of general technical/economic importance.

Q: Who typically uses it?

A: Material suppliers and formulators, engineers specifying materials, quality/test labs, procurement/specification writers, and standards bodies adopting the ISO text nationally or regionally.

Q: Is it current or superseded?

A: The original ISO publication date is 18 November 1999 (Edition 1). The ISO record for this part shows it as published and periodically reviewed (the ISO entry indicates confirmation during systematic reviews), so the 1999 edition remains the current ISO text unless a later revision has been published by ISO. For the authoritative current status always check the ISO catalogue entry or your national standards body.

Q: Is it part of a series?

A: Yes — ISO 14530 is a multi‑part series: Part 1 (designation system), Part 2 (test methods and specimen preparation), and Part 3 (this part — requirement data for selected compounds). See ISO 14530‑1 and ISO 14530‑2 for complementary information.

Q: What are the key keywords?

A: Unsaturated‑polyester, UP‑PMC, powder moulding compound, thermoset, material requirements, ISO 14530, designation system, test methods.
