diffference between ASTMA and ASTM A – Boiler and Pressure Vessel engineering – Eng-Tips

All discontinuities causing complete loss of reflection shall be recorded. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Use a suitable couplant such as water, soluble oil, aztm glycerin.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The holes may be drilled in the plate to be examined if they can be located without interfering with the use of the plate, in a prolongation of the plate to be examined, or in a reference block of the same nominal composition, and thermal treatment as the plate to be examined.
