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.

If the tests cannot be per‐formed on the component due to its geometry, reference may be given to data sheets or to meas‐urements performed on test plates.Characteristic values measured on finished parts can deviate from standard specifications. The de‐viations must be agreed upon with the appropriate Material Engineering department and, if neces‐sary, noted on the drawing.123 3.1Page 3VW 50133: 2015-08AppearanceThe finished parts must be free of flaws and processing defects (voids, cracks, cold shuts, etc.) on the surface.For parts that are subject to high loads or are especially functionally critical, an examination with regard to porosity and appearance as per VW 50093 must be performed. After positive test results,the measured characteristic values must be recorded on the drawing. The appropriate Design En‐gineering department decides, together with the Material Engineering department, on the necessity for porosity specifications.The parts must permit proper assembly. There must not be any functional risks and/or risks of in‐jury for assembly workers due to burrs and/or residual foreign matter becoming loose.ManufactureThe materials are intended for injection molding or blow molding processes.If the PA66 is not modified for impact resistance, using homogeneous regrind from the first machin‐ing process is permissible up to a content of 30 weight percent. Components must be validated with the maximum regrind percentage to be expected. The use of recycled materials, that is, raw materials made from outside processing sources, is permissible only after consultation with the ap‐propriate Design Engineering department and must be explicitly noted on the drawing.ConditioningA distinction is made between "dry " and "conditioned " conditioning states.Specimens from components in the "dry " state have been dried until their weight remains constant (see section 7.2) and continuously stored in a dry atmosphere before the testing. Specimens in the "conditioned " state are specimens in the "dry" state that are aged in a water-tight bag filled with water at 70 °C until the equilibrium state in table 1 is reached. Deviating from this procedure, specimens may also be conditioned as per DIN EN ISO 1110.Evaluation of the measurement resultsThe required numerical values apply to each individual measurement.Material requirementsSpecial requirements on materials (e.g., lightfastness, flammability, emissions) must also be ob‐tained from the drawing.WorkmanshipSee section 7.1.No through-thickness cracks or damage that could impair the function are permissible on the com‐ponent.3.2 3.33.43.544.1Page 4VW 50133: 2015-08Moisture contentSee section 7.2.It must be ensured that the parts are delivered to the plants that will be using them with a minimum moisture content of >0.7 weight percent H 2O.For parts that are clipped, latched, or installed with snap-on hooks during installation, the moisture content must correspond to the equilibrium state specified in table 1, see also section 3.2.Deviations must be noted on the drawing and are permissible only after discussion with the appro‐priate Design Engineering and Material Engineering departments.Melting temperatureSee section 7.3.The melting temperature must be >255 °C.Elevated-temperature behaviorSee section 7.4.The parts must not exhibit any change in shape or surface after heat aging; the dimensional change in length and width must not exceed 0.5%.Low-temperature behaviorSee section 7.5.The finished parts must be fully functional at low temperatures. They must remain free of cracks and other damage after being subsequently heated up to room temperature.4.2 4.34.44.5P a g e 5V W 50133: 2015-08G e n e r a l r e q u i r e m e n t s o n m a t e r i a l sT h e r e q u i r e d p r o p e r t i e s d e p e n d e n t o n t h e f i l l e r m u s t b e o b t a i n e d f r o m t a b l e 1.

Different materi‐als must be agreed upon with the appropriate Material Engineering department. Table 9 – Radiator fan mounting frameNotes on testing WorkmanshipAt least 3 whole finished parts must be stored in a medium that promotes environmental stress cracking (for better comparability, the use of coolant as per TL 774, "G12++" without added water is recommended). The storage period is 48 h at a bath temperature of (135 ± 1) °C. Large parts must be stored in an insulated container made from an inert material, such as stainless steel or glass (no plastic). Circulation must be provided for the bath so that any temperature differences within the whole setup are less than 2 K. Smaller parts may also be stored in suitable, covered containers (beakers with covers/watch-glass) in a circulating air oven. Here, the temperature of the medium must be monitored so that it reaches the desired temperatures.The test medium must be regularly monitored with regard to its effective properties and replaced if necessary. The devices under test (DUTs) must be heated to 135 °C together with the test fluid.After coolant aging, the DUTs must be rinsed with tap water and then dried for 24 h at 70 °C. They are then evaluated.7 7.1Page 11The moisture content is determined by drying the specimens in the (vacuum) oven. At least3 specimens must be taken from 3 parts; these specimens are weighed with an accuracy of 0.01 g and are then dried at 80 °C until a constant weight is obtained. Before the second weighing, the specimens must be cooled down to (23 ± 2) °C in a desiccator. The moisture content may also be determined with commercial moisture meters.Melting temperatureThe melting temperature must be determined by means of DSC (differential scanning calorimetry)as per DIN EN ISO 11357-1.Elevated-temperature behaviorHeat-aging test as per DIN 53497, method B, to be performed on at least one complete finished part.The aging time is (22 ± 2) h and the aging temperature is (150 ± 5) °C unless otherwise specified in the drawing or release.Low-temperature behaviorAt least 2 finished parts that have been conditioned in a standard climate must be aged at (?40 ± 1) °C for (22 ± 2) h.Notched impact strengthThe notched bar impact bending test (impact on narrow side) as per DIN EN ISO 179-1/1eA must be performed. If the standard specimen size cannot be prepared from the part, a specimen with length: (50 ± 1) mm, width: (10 ± 0.2) mm, thickness as in finished product (up to max. 4 mm);notch type: V-notch; support spacing (support width): 40 mm; test equipment: pendulum impact tester 4J may be used.Tensile testThe yield stress and the elongation at break must be determined with a tensile test as per DIN EN ISO 527-1 and DIN EN ISO 527-2, specimen 5A; test speed: 10 mm/min.Aging in transmission fluidBefore the aging in transmission fluid starts, the specimens (dry condition; at least 3 each for the subsequent tensile test and notched bar impact test) must be weighed with an accuracy of 0.01 g.These specimens must then be aged in the defined transmission fluid at 150 °C for 96 h.A second set of specimens must be aged in the corresponding transmission fluid for 504 h at150 °C. The specimens must be stored in closed (non airtight) containers (e.g., watch-glass or alu‐minum foil pressed over the edges). The specimens must be stored at least 3 cm above the bottom of the container.After being removed from the fluid, the specimens must be dried with a cloth, weighed again, and then subjected to the mechanical tests. If the mechanical characteristic values are already outside of the requirements after 96 h, the 504 h aging test must be stopped.7.2 7.37.47.57.67.77.8Page 12VW 50133: 2015-08Heat agingFor heat aging, at least 1 complete finished part and specimens (at least 3 each for each subse‐quent mechanical test) must be aged in a forced-air oven at 150 °C for 1 000 h as per DIN 53497.After aging, the specimens must be stored in a desiccator unless they are subjected to the me‐chanical tests immediately after aging.Aging in engine oilAt least 3 specimens (dry conditioning) for each subsequent mechanical test must be aged at 150 °C for at least 1 000 h in a test oil as per TL 52185 or as per the drawing specification. After completion of the aging period, the specimens are wiped dry and checked with regard to changes in their mechanical properties.Aging in greaseAt least 3 specimens (dry conditioning) for each subsequent mechanical test must be aged at 70 °C for at least 1 000 h in a grease as per TL 745 and TL 735 or as per the drawing specifica‐tion. After completion of the aging period, the specimens are wiped dry and checked with regard to changes in their mechanical properties.Flexural strengthThe flexural stress is determined at maximum load as per DIN EN ISO 178.Specimen with length: (50 ± 1) mm; width: (10 ± 0.2) mm; thickness as in the finished product (up to a max. of 4 mm); support spacing: 40 mm; radius of support: 1.0 mm to 1.2 mm; test speed:(14 ± 1) mm/min.Specimens taken from molded parts with one-sided graining must be placed on the test machine supports so that the grained side faces the loading edge.Impact strengthImpact strength test (impact on wide side) as per DIN EN ISO 179-1.Specimen length: (50 ± 1) mm, width: (6 ± 0.2) mm, thickness as in the finished product (up to a max. of 4 mm); distance between supports (support spacing): 40 mm; test equipment: pendulum impact tester 4J.Specimens taken from finished parts with one-sided graining must be positioned on the supports of the pendulum impact tester with the grained side facing the hammer edge.The specimens must be tested in a "dry" conditioning state.Fan wheel weld line strengthThe flexural stress is determined at maximum load as per DIN EN ISO 178.Specimen with length: (60 ± 1) mm; width: (10 ± 0.2) mm; thickness as in the finished product (up to a max. of 4 mm); support spacing: 40 mm; radius of support: 1.0 mm to 1.2 mm; test speed:(14 ± 1) mm/min.The weld line of the outer fan ring is in the middle of the specimen.The curvature of the specimen points upward and the weld line is at the point where the force is applied.7.9 7.107.117.127.137.14Page 13Figure 1 – Orientation of the flexural specimens; the dashed line marks the meeting zone.(Schematic photo; not necessarily of the part to be tested.)Applicable documentsThe following documents cited in this standard are necessary to its application.Some of the cited documents are translations from the German original.
