Overview
SIST EN 13677-2:2003 establishes general requirements and test methods for glass mat reinforced polypropylene composite sheets (GMT). Published by the Slovenian Institute for Standardization (SIST), this European standard is essential for manufacturers, quality control laboratories, and users of reinforced thermoplastic moulding compounds, ensuring consistent quality, safety, and performance in GMT production and application.
The standard applies to all types of GMT within the scope defined in Part 1 and is focused on key aspects such as sampling procedures, packaging, storage, labeling, and the preparation of test specimens. It details procedures for determining mechanical and physical properties critical to the classification and application of GMT sheets.
Key Topics
General Requirements
- Appearance: Ensures the GMT sheet is free from visible unimpregnated fibre bundles after heating; assesses warpage and rectangularity.
- Packaging: Recommends proper stacking and protection on pallets for transport and storage stability.
- Labeling: Requires clear labeling with essential data such as product code, type, lot number, dimensions, weight, and quantity.
Sampling Procedures
- Guidelines for random sampling from production lots for conformity testing.
- Documentation of sampling results through certificates of conformity, in compliance with EN 10204.
Preparation of Moulded Test Plaques
- Standardized methods for making plaques and cutting test specimens to ensure reproducible mechanical testing.
- Instructions for temperature, pressure, stacking, and cooling during compression moulding.
Test Methods
- Includes normative procedures for:
- Warpage and rectangularity assessment (Annexes A and B)
- Material temperature measurement for blank preparation
- Determination of shrinkage, thermal stability, blank weight, and dimensions
- Evaluation of flow-induced anisotropy and other mechanical properties
- Includes normative procedures for:
Specified and Optional Properties
- Lists required tests for properties such as:
- Dimensions, weight, glass fibre content, density, melting point, crystallization temperature, shrinkage
- Mechanical tests: tensile strength, modulus, elongation, impact strength, thermal expansion, heat deflection
- Additional, application-driven parameters may include flexural strength, compressive properties, electrical characteristics, water absorption, flame retardancy, and more.
- Lists required tests for properties such as:
Applications
This standard is vital across various sectors where GMT is used, providing:
- Quality Assurance: Helps manufacturers maintain consistent product quality through standardized test methods and clear specification of material properties.
- Product Development: Guides designers and engineers in selecting suitable GMT materials for automotive, construction, electrical, and industrial applications.
- Supply Chain Consistency: Ensures suppliers and users share a common set of expectations regarding material properties, sampling, packaging, and labeling.
- Regulatory Compliance: Assists in meeting national and European safety, performance, and quality regulations for reinforced thermoplastic products.
