[MW:23127] Clarification of SA572 Cu content.

Dear Experts,

I have a doubt of the interpretation of SA572

I chemical analysis it states "A Copper when specified shall have a minimum content of 0.20% by heat analysis (0.18% by product analysis)."

I want to interpret the meaning of specified. Is it PO or MTC.

My case is, contractor has purchased the material of structural steel. Their PO dose not mentioned that certificate need to me mentioned about Cu content, but in Lab test certificate the % of Cu is mentioned and it comes below the minimum requirement. The material shall be accepted or rejected.

Can you please clarify the matter.

I am expecting your valuable input and reply.
