You have to read that from the specification for the material of interest, where the permitted tolerances should be stated.

Hello Payam,
 
Please see the extract from API-RP-577, which provides explanations to your query. Ladle or heat analysis is the composition at the and of the melt. Product analysis is the composition  at the end of finished processing.
 
What matters most  in the MTR is the product analysis.
 
Thanks

10.8 MATERIAL TEST REPORTS

Materials test reports, sometimes can be a very valuable tool for the inspector and welding engineer. These are typically notarized statements and are legally binding. There are typically two types of test reports, a heat analysis and a product analysis. A heat analysis, or mill certificate, is a statement of the chemical analysis and weight percent of the chemical elements present in an ingot or a billet. An ingot and a billet are the customary shapes into which a molten metal is cast.

These shapes are the starting points for the manufacture of wrought shapes by the metal-forming process, such as rolling, drawing forging or extrusion. A product analysis is a statement of the chemical analysis of the end product and is supplied by the manufacturer of the material. These reports can be supplied for any form of material, including wrought products, such as plate, pipe, fittings or tubing, castings and weld filler metals. The product analysis is more useful to the inspector and engineer since it provides a more reliable identification of the actual material being used for new fabrication or repair of existing equipment.

Dear Mr. Payem,

You will have to refer particular product specification/ applicable code.

Thanks & regards,

Dear Payam,
If you are looking for the reason of these tolerances, Its because of the reactions which could follow after selecting the sample for ladle analysis, but in heat analysis those reactions are stop.
