Bench Level Automotive Electrical and Electromagnetic Compatibility Validation Test Process Improvements (Analysis of Survey Results from Test Laboratories)

In an effort to reduce the cost and time associated with bench level automotive electrical and electromagnetic compatibility (EMC) validation tests, a survey was created to request advice from the test labs that perform this testing. The survey focuses particularly on the development of the test plan document and the preparation of the test setup. The survey was sent to a targeted group of individuals with experience in performing this type of testing. The invitees work at laboratories that represent the majority of labs in the world that are authorized to perform component electrical / EMC validation testing for automotive original equipment manufacturers (OEMs). There were a significant number of responses; it is possible that representatives from all of the invited laboratories responded. The survey results provide demographic information about the test labs and their participants. The participants possess a tremendous amount of test experience and are therefore qualified to provide recommendations on the subject. The results indicate that the present test situation allows room for improvement. The labs need test plans and equipment in test ready condition with more time prior to schedule testing to prevent delay. Specific test setup and test plan improvement opportunities are rank ordered based on the survey responses. A common test plan format can be developed based on the recommendations provided from the labs. Although it will be challenging, it is recommended that suppliers and OEMs work together with the labs to improve the efficiency of validation testing. The survey results from the labs along with input from the suppliers and OEMs can help to focus further developments.
