EN ISO 14530-3:1999 PDF

Overview

EN ISO 14530-3:1999 is an international standard developed by CEN that specifies the requirements for selected unsaturated-polyester powder moulding compounds (UP-PMCs). This part of the ISO 14530 series focuses on the physical and chemical properties of UP-PMCs and their corresponding compression- or injection-moulded test specimens. The standard targets those powder moulding compounds with significantly different compositions and properties, particularly those of general technical and economic importance.

Key aspects include defining property requirements, selecting appropriate test methods, and classifying moulding compounds according to their composition and characteristics. This classification is in line with the designation system outlined in ISO 14530-1.

Key Topics

• Scope and Application The standard covers UP-PMCs whose compositions vary notably and are used in general technical or economic contexts. It excludes rheological and processing properties limits but emphasizes their importance for practical use.

• Property Requirements EN ISO 14530-3 defines stringent criteria for:

  • Mechanical properties such as stress at break, flexural strength, and Charpy impact strength.
  • Thermal properties including temperature of deflection under load and flammability.
  • Electrical properties such as dissipation factor, volume and surface resistivity, and proof tracking index.
  • Other important factors like water absorption.

• Types and Designation Compounds are divided into types based on filler content and composition, using designation codes consistent with ISO 14530-1. For example, fillers such as glass fibers (GF) and milled fibers (MD), or limestone (LD) are specified by mass content percentages.

• Test Methods The test methods and conditions for assessing material properties are selected from ISO 14530-2, ensuring standardized specimen preparation and property determination.

Applications

• Industrial Manufacturing UP-PMCs compliant with EN ISO 14530-3 are widely used in the production of thermosetting plastic components through compression or injection moulding. They are pivotal in sectors requiring durable, thermally stable, and electrically insulating molding materials.

• Automotive and Electrical Components Due to their mechanical robustness and thermal resistance, these compounds are ideal for manufacturing parts such as housings, connectors, and insulating components in automotive and electrical industries.

• Quality Control and Material Selection The standard assists manufacturers and designers in selecting appropriate UP-PMCs based on quantified mechanical, thermal, and electrical properties to ensure product reliability and performance consistency.

• Research and Development It provides robust guidelines for developing new UP-PMC formulations tailored to specific industrial needs, including optimizing filler types and contents for enhanced properties.
