3.2Appearance and tactile properties
Parts must have a uniform appearance on the entire surface and conform to the drawing requirements, as well as the relea pattern for color, gloss, and haptics..谥法解
Pores, cracks, painters, dust inclusions, spots of incidence, blowholes, bubbles, flow lines and other defects which impair the prescribed appearance are not permissible.
Documentation regarding color and gloss is carried out in the first sample test report according to VW 50190.

3.3Open-air weathering
Open-air weathering according to VW 50185. Complaints from this test procedure oblige the supplier to discontinue the complaints and to improve the surface..
3.4Painting Process
The coating process must be coordinated between the paint shop, the paint manufacturer and the injection molder. The system supplier confirms this in the initial sample test report, i.e. it bears the responsibility to fill the aforementioned requirements.
Responsibility is divided as followings:
–The paint manufacturer informs about the fulfilment of TL requirements, provides its processing guidelines and gives application technical support.
–The paint shop furnishes informs about the underground (plastic type and trade name), earliest checks the requirements (also for pre-production parts), confirms compliance with the processing guidelines (e.g. drying time, temperature, humidity) of the Manufacturer and calls for application technical assistance.
–The injection molder keeps the processing guidelines from the raw material. The substrate/blank must be able to paint in a process-safe. No damage to the raw material may be caud by the injection molding process, so that the varnishing ability is not adverly affected.
3.5Conditioning
All samples delivered for inspection must be preconditioned by the supplier as follows:
7 days at room temperature with a narrow air temperature range (18 °c to 28 °c) or 48 h at 60 °c. After every environmental/ heat aging process listed in Table 3, No. 4.1, 4.2, 5.1, 5.2, 5.3, 5.4. The parts must be conditioned 1 h at 18 °C to 28 °C. The visual evaluation, as well as the tests as per table 3, 2 and table 3, 3 are then performed..
For tho aging process carried out in climatic chambers and heat chambers, the component being tested must be positioned in as-installed position, to the extent possible.
