3.2 Material
See material data sheet and Section 5.6.
The technological material characteristics of the materials ud for the components must ensure the function and safety of the vehicle for the entire rvice life. Fillers such as glass fibers and modifying agents for heat stabilization are permitted.
In the ca of composite components (metal/plastic) compatibility of the materials shall be ensured. If necessary, the materials shall be matched to each other by means of pretreatments (e.g. adhesive agents).
If the material for the finished part is changed during development or during ongoing standard production, this change must be prented and examined in all cas. A new technical engineering relea may be necessary.
Material qualities which have not yet been recorded in the material data sheets must be relead by the Engineering Department and shall fulfill the general requirements of the component. The new material qualities can subquently be included in the material data sheets.
Material data sheets (MDs for short) for the various material types are available from department K-GQL-1/4, they are also available in NOLIS as appendix of this Technical Supply Specification, and can be requested, if required, by the responsible Quality Assurance departments of the manufacturing plants (for an example of a material data sheet, e Appendix A).
3.3 Identification according to VDA1 260
See material data sheet.
3.4 Material Types
Acc. to drawing
3.5 Production
Injection molding process
3.6 Appearance
Surface and interior of the components shall be free of flaws and processing defects, such as flow lin
es, voids, cracks or similar faults. Sink marks at the ba of ribs and reinforcements are permissible only if they do not adverly affect the part’s function or appearance.
3.7 Conditioning
The components and the specimens taken shall be conditioned for at least 48 h before the test in the DIN 50014 - 23/50-2 standard climate (deviating conditioning methods are described in the relevant material data sheets depending on the type of material).
3.8 Evaluation of the measuring results
The required numerical values apply to each individual measurement.

TL 526 31: 2005-10
3.9 Types according to material data sheet
The mechanical material data specified in a material data sheet apply exclusively to that type which has been evaluated positively in terms of the material and relead by the laboratory (according to Section 1.1 of the material data sheet) and which has been produced by one or veral suppliers.
4 General requirements for the finished part
The general requirements apply to every material quality and material combination. Mechanical properties described in the material data sheets may vary in individual cas according to the additional requirements. In every ca, both the general requirements and the material-specific requirements must be met in order to describe the material quality actually ud on a component-specific basis.
4.1 Temperature resistance
The component must be resistant to temperatures from -30 °C to +90 °C and must be functional for the entire rvice life of the vehicle. If necessary, deviating limit temperatures shall be determined; if so, they must always be additionally specified.
4.2 Elevated-temperature behavior
学校像什么See Section 5.1.
The components must not exhibit any changes in shape, color and surface that would adverly affect the function and/or appearance.
4.3 Low-temperature behavior with ball drop test
See Section 5.2.
No cracks, no fractures.
4.4 Resistance to agents
怏怏不乐的意思
See Section 5.3.
The parts shall be resistant to alants and commercial car cleaning and care products such as 5% detergent solution, industrial grade dust remover, and paint cleaner.
There shall be no changes, such as a dissolving process, swelling, discoloration, and/or cracking.
4.5 Aging resistance
See Section 5.4.
The temperature level is bad on the temperatures that the finished part will actually be subjected to. Thus, different requirements could be made on the component in the area of the exhaust system. As the aging behavior is heavily dependent on the material, this may be described in the relevant material data sheet. If there is no information available on the actually occurring temperatures, the principle shall apply that aging must take place for 200 h at +150 °C (mechanical circulation oven).

4.6 Laboratory weathering tests
Sun test acc. to Test Specification PV 1323 240 h and 480 h ∆L    2 to -2
Gray-scale level ≥ 4 acc. to DIN EN 20105-A02. No relea
criterion; rves to asss the risk of the long-term tests
(acc. to PV 3929 and PV 3930)
Kalahari test acc. to PV 3929 (1-year cycle) The evaluation is performed visually; no fading to gray and/or decomposition;    a soot-like covering can be accepted, provided it can be completely removed.
Florida test acc. to PV 3930 (1-year cycle) The evaluation is performed visually; no fading to gray and/or decomposition;    a soot-like covering can be accepted, provided it can be completely removed.
4.7 Resistance to open air weathering
Resistance to open-air weathering according to VW 501 85.
For risk asssment, the tests shall be conducted as described under Section 4.6.
4.8 Sealant removal test
See Section 5.5.
There shall be no changes, such as a dissolving process, swelling, discoloration, and/or cracking.
4.9 Paintwork奇妙的克隆
According to TL 211; only if required in the drawing.
5 Notes on testing
5.1 Elevated-temperature behavior
电子报税
Aging at elevated temperature according to DIN 53497, method B, to be performed with at least one complete component.
Aging period: (24 ±  2) h头部经络图
Aging temperature (unless otherwi specified): (90±  1) °C.
5.2 Low-temperature behavior with ball drop test
参公管理Ball drop test according to PV 3905 with at least three (70 x 70) mm finished part ctions that are as plane as possible, but with a ba plate (specimen support) made from ≥10 mm thick sheet steel without recess; ball weight is (880 ±5) g; ball drop height is (650 ±10) cm; ball impact location in specimen center of painted or grained upper surface.

5.3 Resistance to agents
Finished part ctions measuring (80 x 20) mm shall be immerd for 30 min at (23 ± 2) °C (only one half of each ction) in
─  5 % detergent solution
─industrial grade dust remover
< products from the VOTEX range
─paint cleaner
─paint alant
海米冬瓜怎么做(at least 1 specimen per medium). This treatment is to be followed by a 24 h period of aging in air at (23 ± 2) °C (having removed the specimen from the medium, let excess medium drip off only). Afterw
ards, the specimens shall be rubbed clean with a cloth soaked with water (for industrial grade dust remover and detergent solution) or with petroleum ether. Subquently, the specimens are evaluated.
5.4 Aging resistance
Permanent aging at elevated temperature in mechanically circulated air
Test equipment: Mechanical circulation oven
Test temperature:(150 ± 1) °C; the test chamber shall be t to generate a mean temperature of +150 °C in the immediate vicinity of the test speci men (check with a calibrated
digital thermometer, with the nsor placed near the specimen).
Specimen: 100 x 10 mm trour specimens; quantity: 10
Procedure: The test specimens are placed in the pre-heated circulation oven that is t to the test temperature. After a period of 150 h the first trour specimen is taken from
the oven and, after cooling down to +23 °C (approx.30 min), is slowly bent
between finger and thumb until both ends meet. The smooth, non-painted side of
grained and painted specimens is the tension side. If this specimen does not
show signs of cracking (white cracking is permissible), it is placed back into the
oven and after another testing period of 24 h is tested again, etc. If there are
signs of crack formation, another, previously untested, trour specimen shall be
taken from the oven to be evaluated. End of testing is reached when a hitherto
untested specimen immediately cracks when bent for the first time.
5.5 Sealant removal test
The alant removal test is performed as follows: The finished part is wetted with alant remover (Halpasol 190/240 from the company Haltermann; depending on the location, the alant remover normally employed there can also be ud) using a staurated cotton rag by intensive wiping motions in longitudinal direction (ten times in each direction with a pressure load of approx.

(7 N at +23°C). The finished part is visually evalu ated after 24 h flash-off time.
5.6 Material
Identification can be performed using the attenuated total reflection variant of the FTIR (Fourier transform infrared spectroscopy) procedure.
5.7 Density
Buoyancy method; any existing coat of paint need not be removed.
Three specimens shall be tested.
