Accept the Inward Raw Material from the mines site, only if impurity level is less than acceptable limits.
Accept the Raw Material only If whiteness is equal to or more than the standard sample or acceptable limit or
as per the purchase order specs.
Accept the material only if chemistry is as per requirement.
Follow decision rule for reconfirmation.If failure is confirmed, reject the shipment or accept for sub standard quality under concession. |
