Guest guest Posted May 10, 2004 Report Share Posted May 10, 2004 Simon Here is an email from Samuel regarding metal testing for Sheng chang. I also have several test reports from Sheng Chang, and they do include breakdown of the metals. Dear Dr. Marcus. The specification of total Heavy metal is 50ppm. If our Lab test the total Heavy metal more then 10ppm then will go further detail objects test. Samuel Quote Link to comment Share on other sites More sharing options...
