Testing of Material Properties
We ensure quality through testing of material properties (according to EN ISO standards):
Property | Unit | Standard | Description |
|---|---|---|---|
Density | g/cm³ | EN ISO 1183-1 | control of material consistency and processing |
Hardness | ShA-ShD | EN ISO 868 | resistance to surface indentation |
Tensile strength | MPa | EN ISO 527-3 | maximum stress before breaking |
Elongation at break | % | EN ISO 527-3 | ductility and flexibility of the material |
Low-temperature flexibility | ˚C | EN ISO 495-5 | crack resistance under cold conditions |
Vicat B | ˚C | EN ISO 306 | material softening point under load VST |
Plasticizer content | EN 14372 | determination of type and quantity of plasticizers to ensure safety and compliance | |
Melt Flow Index | EN ISO 1133 | ||
Thermal stability min. | resistance to degradation at elevated temperatures | ||
Colour | Spectrophotometric method | objective colour control (CIELab system) |
