EN ISO 14530-2:1999 PDF

Overview

EN ISO 14530-2:1999 specifies standardized methods for the preparation, conditioning and testing of unsaturated‑polyester powder moulding compounds (UP‑PMCs). It defines how to prepare test specimens (by injection moulding or compression moulding), the conditioning regimes to be used before testing, and the test methods for determining rheological, mechanical, thermal, electrical and other material properties. The part ensures reproducible and comparable data for UP‑PMCs used in design, quality control and material comparison.

Key Topics and Requirements

• Scope and purpose: Methods for specimen preparation, conditioning and property determination specific to UP‑PMCs; requirements for handling and storage (moisture‑proof containers).
• Specimen preparation:
  • Use a single, consistent moulding procedure (injection per ISO 10724 series or compression per ISO 295) and fixed processing parameters for each data set.
  • Machining of specimens from moulded plates is covered (ISO 2818, ISO 3167).
  • Typical processing ranges are provided for melt and mould temperatures, pressures and cure times to ensure complete, homogeneous cure.
• Conditioning: Two main regimes:
  • Method 1: Condition in standard atmosphere (ISO 291) - at least 16 h at 23 ± 2 °C and 50 ± 5 % RH.
  • Method 2: 24 h immersion in distilled water at ambient temperature followed by 2 h in ISO 291 conditions.
• Properties and test methods: Selected from ISO 10350‑1 and other relevant standards; includes:
  • Rheological/processing: shrinkage, transfer flow, thermal flow.
  • Mechanical: tensile (ISO 527), flexural (ISO 178), Charpy impact (ISO 179), puncture impact, hardness.
  • Thermal: deflection temperature (ISO 75), coefficient of linear thermal expansion (ISO 11359‑2), flammability/oxygen index (IEC/ISO methods).
  • Electrical: permittivity, dissipation factor, volume/surface resistivity, dielectric strength, proof‑tracking index.
  • Other: density (ISO 1183), water absorption (ISO 62).
• Reproducibility emphasis: Specimen dimensions, conditioning and test procedures specified to make results comparable; results may differ if other dimensions or procedures are used.

Applications and Users

• Who uses it: Materials engineers, test laboratories, quality‑assurance teams, compound and parts manufacturers, product designers, and standards committees.
• Practical uses:
  • Characterizing and comparing UP‑PMC grades for selection and specification.
  • Establishing quality control test methods and acceptance criteria.
  • Supporting product development, failure analysis and regulatory/flammability compliance.
  • Producing comparable databooks for procurement and design (consistent with ISO 10350‑1 data presentation).

Related Standards (if applicable)

• ISO 10350‑1 (data acquisition/presentation for moulding materials)
• ISO 10724‑1/2 (injection moulding of PMC specimens)
• ISO 295 (compression moulding of thermosetting test specimens)
• ISO 291 (standard atmospheres for conditioning)
• ISO 527, ISO 178, ISO 75, ISO 1183, ISO 2818 and relevant IEC flammability and electrical test standards
