Thanks for yr reply.
Sorry for delayed reply because i am on the way to hongkong now.
Sorry we do not have any documents for the testing. Because every time our customer test them. They only send email saying that they pass the testing. Then we finish the production.
There may be place in china to make this this testing but if we do now we need time and money for that. Not that quick.
U may check if u have place at yr side to do this. If yes. Better that we supply u testing samples and u do testing at yr side and them show to yr customer the result. Tks!
