Question :What is the difference between ASME and ASTM ?
Answer:
ASME - American Society OF Mechanical Engineers .
ASTM - American Society of Testing Metals .
ASTM standards deals with material grading/properties / tests and specify them whereas ASME standards deals with mechanical engineering subjects and specify / recommend standard practices .
The American Society for Testing and Materials (ASTM) issues standards on material properties and testing. The American Society of Mechanical Engineers (ASME), meanwhile, specifies standards for materials to be used in construction and infrastructure. The correct standard to use is based on the specific contract or on local laws. The difference between the two sets of standards is less concrete--even for concrete.
