Overview

EN 13677-2:2003 is a CEN European standard that specifies methods of test and general requirements for glass mat reinforced polypropylene composite sheet (GMT). It is Part 2 of the EN 13677 series and covers the procedures for sampling, packaging, storage and labelling of GMT, plus the preparation of moulded test plaques used to produce specimens for mechanical testing defined in Parts 1 and 3. The standard ensures reproducible conditioning and testing of reinforced thermoplastic moulding compounds for reliable quality assessment.

Key Topics and Technical Requirements

  • Scope and purpose: Defines general requirements applicable to all GMT types within the EN 13677 series and describes plaque preparation for mechanical property testing.
  • Sampling and certification: Requirement for manufacturer testing per lot and issuing a Certificate of Conformity (in line with EN 10204). Sampling rules for routine testing and dispute resolution are defined (e.g., 30 blanks for dimensional checks; 5 blanks for fibre-content/density).
  • Packaging and labelling: Pallet packing suitable for forklift/road transport and mandatory label information (designation code, product type, lot/pallet numbers, blank dimensions, gross/net weight).
  • Plaque and specimen preparation: Specifies mould area (minimum 200 × 200 mm), target plaque thickness (4 ± 0.2 mm), blank stacking orientations (0°/90° or 0°/0° depending on reinforcement), and blank temperature for moulding (210 ± 10 °C determined per normative annex H).
  • Appearance and dimensional tolerances: Requirements for impregnation (no visible unimpregnated fibre bundles after heating), methods to determine warpage and rectangularity (normative Annexes A and B).
  • Test procedures: Normative annexes detail procedures for warpage, rectangularity, blank temperature, blank weight/dimensions, shrinkage, thermal processing stability and flow-induced anisotropy.

Applications and Who Uses It

  • Manufacturers of GMT and composite sheets - for internal quality control, batch certification and process validation.
  • Third‑party testing laboratories - to prepare standardised test plaques and specimens for mechanical property assessment.
  • OEMs (automotive, transport, consumer goods) and procurement/specification engineers - to set material acceptance criteria and supplier contracts.
  • Quality managers and regulatory bodies - to resolve disputes through prescribed re-sampling and re-testing methods.
  • Typical application sectors include automotive body panels, structural components, and other components where reinforced thermoplastic moulding compounds are used.

Related Standards

  • EN 13677-1 (Designation) and EN 13677-3 (Specific requirements) - other parts of the EN 13677 series.
  • Normative references used within EN 13677-2: EN 10204, EN ISO 527 (tensile), EN ISO 1172 (fibre content), ISO 1183 (density), EN ISO 3146, EN ISO 6603-2 and others relevant to plastics and composite testing.
