1 General
1.1 Scope
The test specification is an integral and binding part of the specification book, quality specification and/or drawing. It shall be applied under the following conditions:
Relea investigations in ca of new designs
territorial
Relea investigations for components of sub-suppliers
Design changes compared to engineering relea level
Depending on the particular concept and bad on findings in the development process, further tests may be required over and above tho described herein, which would have to be agreed and coordinated with the responsible BMW test department. Tests that are carried out within the scope of initial sample inspection shall be agreed with the responsible BMW quality departments.
1.2 Information protection

This document is subject to the information protection regulations according to BMW-Guideline-6 dated
15.07.2002 "Security, information protection, fire prevention".
1.3 Quoted standards and specifications
DIN Standards:

英语短文1.4 Scope and purpo
The climatic test rves to validate bonded joints or similar joints such as lamination, back compression moulding, in-mould lamination, back foaming, moulding and welding. This testing method must always be applied when the material joint is more chemical and not mechanical (e.g. screws, staples, rivets, hot riveting).
1.5 General test conditions
1.5.1 Number of test specimens
celebrity
The test shall be carried out on at least 5 new parts in all material variants.
If colour has an influence on the production process, the different colours must also be tested.
1.5.2 Test t-up
Spatial arrangement of test specimens should correspond to fitment position in vehicle. Parts can also be tested in mounted condition. If the degrees of freedom of mounting points and contact geometries have an influence on bonded joints, the fitment condition in the vehicle must be simulated on at least one part.
When testing in unmounted condition, the following should be obrved:
•No contact with walls and floor of climatic chamber.
•Spatial arrangement identical to fitment position in vehicle.

2 Test chamber
2.1 General
It must be assured that all test specimens in the climatic chamber are subjected to the same test conditions. Any interaction of test specimens (e.g. deformation due to stacking of specimens) must be ruled out.
The climatic chamber ud must capable of realising the specified cycles in the specified time (especially the changing speed of temperature and humidity).
If one of the components or an asmbly is deformed during the test, only the bonded joint or materi
advertir
al joint must be evaluated and not the deformation. The evaluation of component behaviour (e.g. discolouration or deformation) shall be subject to the currently valid version of PR 303.

Test procedure must be documented by means of a suitable data logger for each test particularly with regard to test cycles, temperature and humidity over time.
Proof of regular calibration shall be provided without further request.
