14、ductions authorized.STP537-EB/Oct.1973 Introduction In the June and August 1971 issues of Materials Research and Standards,a forum was provided by the American Society for Testing and Materials(ASTM),in conjunction with the Cryogenic Society of America(CSA),so that cryogenic standards could be estab
15、lished.Nine papers describing the progress being made on solving problems in the cryogenic region,aimed es-sentially at work being conducted by Committee F-7,were published.We have come a long way since the first attempt in 1967 in development procedures,and now this book describes the efforts being
16、 made,not only in support of the aerospace,but also in support of nondefense industries.ASTM and CSA are becoming the focal points for standards as they now impact on the entire cryogenic industry.The need for standards is perfectly clear as the nation begins to solve the pollution and energy crises.The base for developing these necessary stand-ards was provided by ASTM in their charter for Committee F-7.This has been expanded as described by the papers on Cryogenics in Materials Re-search&Stand
