文摘Seven sandwich construction properties test methods of the national standards(GB/T1452-1457,GB/T1464),which published in 2005 by People's Republic of China.Based on a large number of experiments and design,refer to international advanced national standards,with international advanced level,from the specimen size,experiment methods,laboratory fixtures,the calculate results are all more reasonable,scientific,comprehensive and practical than the international advanced country standards.This paper specifies the test validation report of the test method for edgewise compressive properties of sandwich construction,the test data results of the specimen size,experiment methods,load speed,calculation formula and other aspects,to show the rationality and scientific of the technical requirements by national standards,and particularly taking into account the thickness of different facings,calculation formula of the edgewise compressive properties of sandwich construction with different facings,which is international advanced national standards do not have,currently.
