Both are corrosion tests; what is the specific difference?

21433 is \"Inspection for Intergranular Corrosion Sensitivity of Stainless Steel Pressure Vessels\", which specifies the rules and requirements for testing the intergranular corrosion sensitivity of stainless steel pressure vessels. And 4334 refers to the specific testing methods and requirements.

Thank you. Then for the technical specifications of the atmospheric pressure equipment, which one should I use?
