acceptance criteria of PMI

Dear Experts,
in some PMI reports i found a comment written in bottom side----the measured value of alloying elements shall be within 10 percent of the specified level------from where this tolerance has been taken? is it mentioned in code anywhere?

In Reply to vivek at 15:13 May-09-2016 (Opening).

For acceptance criteria of PMI, it shall be demonstrated that materials contain the amount of alloying elements shown in the material specification. Alloys shall be deemed acceptable if the alloying elements are each within ten percent (10%) of the values.
Welds having consumable material content that matches, or nearly matches, the base metal composition within approximately twelve and half percent (± 12.5%) of the ranges allowed in ASME Section II, Part C for each element.
Acceptance criteria for dissimilar metal alloy welds shall be in accordance with the welding consumable material specified in the approved welding procedure. The effects of dilution between the different base metals and the filler metal shall be taken into account when determining the nominal as-deposited weld metal composition.
