HEAVY METAL TESTING SERVICE
The elements of heavy metal are usually used on the material of electronic and electrical products
Recently, more and more regulations require that the heavy metal in materials should not exceed the prescribed limits. What kind of heavy metal element are used in material? The following table can provide a reference:
