Elastomer sealing material made of cellular rubber
The technical delivery condition TL 52065 of Volkswagen AG contains material requirements for elastomer sealing material made of cellular rubber, e.g. of the materials SBR or EPDM. It refers to moulded or extruded articles and damping material. Required tests are for example:
- For interior parts: Emission tests according to VW 50180
- Residue on ignition according to PV 3927 (thermogravimetry)
- Density (DIN EN ISO 1183-1)
- Air ageing, heat storage, water storage (DIN 53508)
- Tensile strength and elongation at break (DIN 53504), compression hardness (DIN EN ISO 3386), compression set (DIN EN ISO 1856)
- Cold behaviour, corrosion behaviour and ozone resistance according to specification of VW 2.8.1.
- For exterior parts: Weathering in dry-hot (PV 3929) and humid-warm climate (PV 3930); for interior parts, hot exposure (PV 1303).
- Colour fastness test according to DIN EN 20105-A02
Tests are often combined, so that a storage/simulation is usually followed by a test of the mechanical properties tensile strength, elongation at break and compression hardness in addition to the visual inspection.
We will be happy to provide you with a non-binding quotation for tests in accordance with TL 52065, tailored to your requirements.
