Parts with qualities that cannot be classified on the basis of this standard require separate Technical Supply Specifications (TLs) or notes in the respective drawing.DefinitionsThermoplastic elastomers (TPE)Thermoplastic elastomers are elastomers that have a flow transition at temperatures greater than the application range.These elastomers are multi-phase materials that contain hard and soft segments as blocks in the main chain or hard segments grafted as side chains on flexible base chains. The soft segments form the movable areas necessary for the rubber elasticity.

Within this context, "recycled material" refers to products from a recycling process (thermal, mechanical, and/or chemical) used to recycle material from used com‐ponents.For components subject to dynamic loads, using regrind (from the material fed directly into the components' own manufacturing process) is permissible up to a limit of 20%, provided that the re‐quired material level for the component is consistently reached so that the use of regrind does not have a significant impact on the required material properties.TPE qualities are preferably tested on components, component sections or, in exceptional cases,test plates.Samples must always be delivered with the manufacturer’s quality designation.The number of parts required for laboratory tests must be agreed upon with the appropriate Materi‐als Laboratory in each case.When manufacturing plate material, anisotropic effects (= orientation of macromolecules during production) can be expected as a result of the molding material injection process (gate marks).This will lead to differences in the mechanical characteristic values of strength and elongation de‐pending on the direction of the orientations. This must be taken into account during testing. To this end, appropriate specimens must be taken from the plate material both in the longitudinal and transverse directions and torn apart. Generally, the specimens taken transversely to the direction of orientation of the macromolecules will have lower strength and elongation values.The specimens to be used for laboratory tests as per this standard must be taken transversely to the orientation of the macromolecules.Evaluation of the measurement resultsThe required numerical values apply to each individual measurement.Color in as-received conditionAs per drawing.AppearanceNo visible flaws, inclusions, etc.Material identificationInfrared spectroscopy, pyrolysis gas chromatography mass spectrometry (Py-GC-MS)couplingPy-GC-MS as per Test Specification PV 3935.ThermogravimetrySee section 6.1.Volatile, polymer, and nonvolatile percentages must be specified.4.24.34.44.5 4.5.14.5.2Page 4VW 50123: 2015-09Differential scanning calorimetry (DSC)See section 6.2.The following must be specified: Enthalpy of fusion, melting range (T m reflects the start of melting,not the peak maximum), 1st heat-up curve, 1st crystallization curve, 2nd heat-up curve, and 2nd crystallization curve.Dimensional stability under heat as per DIN EN ISO 306, method BOnly if required in the drawing; as per the released sample.Density as per DIN EN ISO 1183-1Specified as per drawing.Hardness Shore AHardness range of 55 Shore A to 80 Shore A for TPE that are primarily exposed to daylight and weather effects (e.g., TPO, TPV).Shore DHardness range of 40 Shore D to 50 Shore D for TPE that may also come into contact with operat‐ing fluids such as oils, greases, fuels, blowby gases (limited resistance) (e.g., TPC).Low-temperature elasticity after 22 h at -40 °C GeneralrequirementsNo cracks or fractures under manual bending stress.Freeze temperature T GAs per drawing.Ozone resistance as per VW 2.8.1, installed in a manner similar to that used during op‐erationFree of cracks.Flammability as per TL 1010As per drawing.Lightfastness as per VW 2.8.1No changes compared to the as-received condition, e.g., discoloration, embrittlement, decomposi‐tion, cracks.

The test is performed under normal atmospheric conditions. In order to evaluate the enthalpy of fusion of the polymer, the resi‐due determined with the thermogravimetric analysis must be subtracted from the actual original specimen weight.Heat agingAging in a forced-air oven as per DIN 53508. The aging durations and temperatures must be agreed upon.
