3.3 Manufacture

Injection molding method.

3.4 Quality

See Table 1.

3.5 Identification according to VDA 260

See Table 1.

3.6 Conditioning

The specimens shall be conditioned prior to testing for a minimum of 48 h in the DIN 50014-23/50-2 standard climate at (23 ± 2) °C and (50 + 6)% relative humidity.

Both unconditioned and conditioned components shall be tested. These requirements will reveal whether a component can be used even if it is not conditioned.

3.7 Evaluation of the measuring results

The specified numerical values apply to each individual measurement and each point on the finished part.

3.8 Workmanship

See Section 5.9.

Only those parts that come into contact with coolant have to be tested. The visual appearance of complete molded parts after aging in a medium with decreased surface tension is evaluated. There shall be no through cracks. On molded parts that come into contact with coolant as part of their function, this requirement especially applies to areas where coolant is carried, such as hose studs, sealing surfaces and walls.

D 5 Notes on testing

5.1 Material

The identity test can be performed by infrared spectroscopy or DSC.

content

5.2 Moisture

A minimum of three specimens measuring (20 x 20) mm shall be removed from different points on the finished part; they shall be weighed with an accuracy of 0.01 g and dried in a vacuum until the weight value remains constant. Cooling of the specimens to (23 ± 2) °C, which is necessary for the second weighing procedure, shall be performed in a desiccator.

5.3 Ball indentation hardness

The measurements must be performed on at least three specimens (minimum thickness 4 mm) measuring (20 x 20) mm (two measurements per specimen). The grained surface of specimens, which have been taken from finished parts with one-sided graining, shall be removed using a surface grinding machine. The measurement is performed on the ground side.

5.4 Polymer viscosity number

Solvent: sulfuric acid, test temperature (40 ± 0.1) °C.

resistance

5.5 Aging

Complete finished parts or finished part sections shall be aged for 1,000 h at (150 ± 1) °C in a drying cabinet. The viscosity number of the polymer is determined after cooling to (23 ± 2) °C.

behavior

5.6 Elevated-temperature

Aging at elevated temperature test according to DIN 53497, method B, to be performed on at least one complete finished part. Aging time is (22 + 2) h; aging temperature unless otherwise stated in the drawing or release is (90 ± 1) °C. This temperature is (120 ± 1) °C for those vehicle passenger compartment parts that are exposed to a higher level of sun radiation, such as on the dashboard or upper edge moldings of the door and side trim panel.

behavior

5.7 Low-temperature

Aging of at least one complete finished part in air at (-40 ± 1) °C; aging period: (22 + 2) h.

5.8 Lightfastness

If the number of exposure periods is not defined in the drawing, the following rule applies:

─three periods of exposure for components in areas with indirect sun radiation

─five periods of exposure for components in areas with direct sun radiation (e.g., door upper trim)

─ten periods of exposure for components in areas exposed to a higher level of sun radiation

(e.g., rear shelf)

5.9 Workmanship

A minimum of 3 whole finished parts are aged in coolant according to TL 774 without adding water. The type currently used for the factory filling is to be used.

Aging period: 48 h; aging temperature: (135 ± 1) °C.

Aging is to be performed using a thermostat with circulated bath (e.g., Lauda Ultra Thermostat Type U12 manufactured by the measuring instruments company Lauda Dr. Wobser KG), filled with the test fluid.

After coolant aging the specimens shall be rinsed with tap water, to be followed by drying for 3 h at +70 °C. Having undergone this treatment, the specimens shall be evaluated.
