Well, you post regularly here, so you probably really know why no-one answered. It simply isn't satisfactory to try to explain the differences between two editions of a standard, unless the difference is trivial. And what is trivial in the context of one product may be far from trivial in the context of another. It may be particularly difficult in the case of CISPR13, because it's a very old standard and the structure has degenerated. Bits and pieces have been added over the years, so determining the changes between editions requires a line-by-line comparison - time consuming! Add to that the likelihood that few people here use CISPR 13, which is about emissions from consumer products.... I'm afraid you have to buy it. With the recent information posted here about low-cost editions published in English by Netherlands, Danish and Luxembourgeois standards organizations, it may not be so painful. Incidentally, your information about Japan may be out-of-date, or soon will be. CISPR 13 has been revised yet again: CISPR 13 (2006-03) Ed. 4.2 Consolidated Edition Sound and television broadcast receivers and associated equipment - Radio disturbance characteristics - Limits and methods of measurement Maintenance Result Date: 2009 CENELEC hasn't yet adopted this edition, but no doubt soon will. -- OOO - Own Opinions Only.
