9、e specified, minimum 20 pieces of microenclosed screws shall be tested according to this specification. 3.1.4.2 Screws shall satisfy the test in DIN 50049-2.3, prior to coating with adhesive. 3.2 Conditions. 3.2.1 Conditioning. If nothing else specified at the individual tests, the tests are perform
10、ed without conditioning in the delivery state at +23 E 5K. The test piece surface shall be free from pollutants, such as anticorrosive or parting agent. 3.2.2 Test Conditions. Deviations from the requirements of this standard shall have been agreed upon. Such requirements shall be specified on compo
11、nent drawings, test certificates, reports, etc. 3.3 Safety. This standard may involve hazardous materials, operations, and equipment. This standard does not propose to address all the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropri
12、ate safety and health practices and determine the applicability of regulatory limitations prior to use. 3.4 Documentation. Samples of components or material released to this standard shall be tested for conformity with the requirements of this standard and approved by the responsible GM Department p
13、rior to the start of delivery of production level components or materials. Any change to the component or material, e.g., design, function, properties, manufacturing process and/or location of manufacture requires a new release of the product. It is the sole responsibility of the supplier to provide
14、 the customer, unsolicited, with documentation of any change or modification to the product/process, and to apply for a new release. If not otherwise agreed to, the entire verification test shall be repeated and documented by the supplier prior to start of delivery of the modified or changed product
15、. In some cases, a shorter test can be agreed to between the responsible GM department and the supplier. 4 Requirements and Procedure 4.1 General Requirements.
