Sample QC

Hi,

When we select any New Vendor for purchase of material, first we get some sample from that Vendor and do QC. If the material passes QC test, only then we start buying material from that Vendor and do regular QC.

What I want to know is there any separate procedure for Sample QC and regular QC. If there is any, then I would like to know what are the procedure for Sample QC and regular QC.
