Plastics - Determination of compressive properties
|Publication Date:||20 May 2011|
|ICS Code (Plastics in general):||83.080.01|
This Standard specifies a method for determining the compressive properties of plastics (compressive strength, compressive modulus and compressive stress/strain curves) under defined conditions. A range of test speed is included.
The method applies to the following range of materials:
- rigid and semi-rigid (JIS K 6900) thermoplastic moulding and extrusion materials, including compounds filled and reinforced by e.g. short fibres, small rods, plates or granules in addition to unfilled types;
- rigid and semi-rigid thermoset
- thermoplastic liquid -crystal polymers.
In agreement with JIS K 7140-1 and JIS K 7140-2, this Standard applies to fibre- reinforced compounds with fibre lengths < 7.5 mm prior to processing.
The method is not normally suitable for use with materials reinforced by textile fibres (ISO 3597-3 and JIS K 7018), fibre-reinforced plastic composites and laminates (JIS K 7018), rigid cellular materials (JIS K 7132) or sandwich structures containing cellular material or rubber (JIS K 6254.).
