12、ess, 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. In some cases, a shorter test can be agreed to between the responsible GM department and the s
13、upplier. 4 Requirements and Procedure 4.1 Sample Preparation. Samples must be greased according to requirements in drawings. 4.2 High Temperature Exposure. The sample must meet all test requirements after exposure to 100 E for 30 minutes and cooling to room temperature in the environment chamber. 4.
