14、ment.No further reproductions authorized.Introduction STP543-EB/Jan.1974 This symposium attempts to update our knowledge of hydrogen em-brittlement by presenting new test methods in comparison to those which have been in use for years.The old test methods have been used to eval-uate the classic sour
15、ces of internal hydrogen embrittlement(IHE),such as pickling and plating.New test methods have been devised to evaluate materials susceptibility to high-pressure gaseous hydrogen environments(HEE),such as found in storage tanks,turbine engines,and power units.The purpose of the first part of this bo
16、ok dealing with IHE is to present a wide range of methods for measuring,detecting,and testing for the phenomena of hydrogen attack.This portion of the book illustrates the lack of a standardized approach resulting from various philosophies and personal preferences as to test methods.This initial effort should point the way for development of long-needed ASTM methods on the subject of IHE.The second part of this symposium deals with HEE and also clearly shows the need for test methods to produce
