Dear Doug, Very interesting question and I would like to know it as well. Suggest to go to the testing lab for the answer. They should have the statistics in their business.
Would you mind sharing why you want to know it, what for? Although I do not have the figures I am aware of the answers why the product cannot pass the test in the first attempt. Below is my experience in dealing with Asian suppliers in the past many years. - No safety engineer to go thru the design against the applicable standards before submitted for testing. - No proper facilities to conduct the pre-tests. - The employer does not recognise the importance of this position and results in no safety engineer in the manufacturer. The design engineer is also not brave enough to tell the employer that they do not have knowledge, experience and test facilities in doing the relevant test work so the employer believes he/she looks after this as well. - The design engineer does not have relevant knowledge and training for the test work. There is little education system in current universities/vocational institutes to help the society. Most test engineers in public test labs are trained by the employers, not from the current educational system. Some small associations (TIC - Testing, Inspection & Certification) from the industry are setting up routes to be certified testing professionals in the current educational system with the help from the Government Industry Department. Just some improvement but not sufficient IMO! Based on the above facts, it leads to other potential issues in the finished products. Even if the product has passed the conformity test, the manufacturer may not know why their design meets the requirements. How can they maintain the compliance in production? If the manufacturer does not have this knowledge, how can they plan their assurance protocol for mass production in order to validate the finished products in compliance with the original design limits before leaving the factory?
