New version of ASME code book, 2007 Ed. says ISO 148-1,2,3 the applicable version is 2006, but only ISO 148-1 İS İN 2006 version. ISO 148-2 and -3 is in 1998 version.
Does ASME make a mistake?

-direct method; in which the national instute can give a service
-indirect method; in which the specimens are to be called from body who'll calibrate the machine ?
