Abstract: Based on GB/T 230.1-2009, national standard GB/T 230.1-2018 was got from revising and applying international standard ISO 6508-1:2016. Through comparing with the previous version standard, the new standard revision contents including the name, scope, normative references, principle, symbols, abbreviated terms and designations, testing machine, test piece, procedure, test report, annex C and annex D were introduced and analyzed in detail. The result shows that revisions such as introducing JJG 112, stipulating that a daily check for hardness tester should be done before test, revising annex C, changing annex C and annex D from informative annex to normative annex etc., were all very important modification for the new standard. Compared with previous version standard, GB/T 230.1-2018 is more complete, more rigorous and easier to carry out, and has obvious progress.
