Dear Netspyking

I looked all over the forum. Unfortunately the ISO 20765-2 and -3 are not available.
Also at the ISO website, the ISO 20765-2 is under development. Then why many forum members ask for it? Is a draft version in the public domain?

If you have something related to this standard please share it.

Best regards. Walter.

Maybe it is a bit late to answer this one, but anyway ... In my understanding, all parts of ISO 20765 are (or will be) a reworking of GERG-2008. I have not found that one for free, but maybe somebody else can. Its predecessor, which I understand is similar, is GERG technical monograph TM-15, which is available free. The PDF is the second link on this page: The trouble with the GERG document is that it is a technical paper rather than a standard, so you have to dig through a lot of information about research methods to get to the interesting bits. I have seen a draft of ISO 20765-2, but unfortunately do not have a copy - sorry about that - but there must be copies out there somewhere. According to the ISO web site, ISO 20765-2 has completed all its approval stages and is on its way to the printers, so copies of the real thing should be around soon. Nothing at all seems to have been done about ISO 20765-3 so far.

Best regards
