Although generally in agreement with you Graham, as I can't find EN 60445 listed in either the European Journal for the Machinery Directive or the Low Voltage Directive it seems that this standard does not give "presumption of conformity" for any of the Essential Health & Safety Requirements of these CE marking Directives. EN 60204-1 does however.
My mistake - EN60445 is not a HD, but does implement and supersede the former HD324 S1 1977 on colours (as stated in EN60446 previously to this being incorporated in EN60445)
My own analysis of the standards show that there is broad agreement between EN 60445 (HOWEVER I am assuming it has the same or similar info as the old EN 60446 which is one of the 2 standards the latest version replaces) and BS 7671 and doesn't generally contradict EN 60204-1.
I think it's fair to say that BS EN60204-1 is compliant with BS EN60445. BS7671 is, with the exception of specifying the colour "cream" for Telecomms Functional Earth with no protective function (see also my comment on this below).
I would be interested if it still says "blue" for neutral rather than "light blue" as EN 60204-1?
"LIght Blue" is still a recommended description as stated in BS EN60446.
It would be far better if all these 3 standards FULLY agreed rather than generally agreed.
Yes, I concur. No reason for different approaches.
I also don't know why BS7671 still talks about functional earth being "cream", when IEC757 - which is
an HD (HD457 S1, implemented in UK as BS7645) talks about "White"."Cream" is not included for "designation by colour" in either BS EN60445 or IEC757 (BS7645) to which BS EN60445 refers (see Note in Clause 6.1).
