Such as Appendix "A" in UL2601 - "General Guidance and Rational" I've been in this section more than once and find it very useful. Also for medical - The European Commission puts out "Working Documents" titled MEDDEV's. These are used to explain and define either a directive, or define terminology within directives, very useful documents. Some do exist today, but more certainly wouldn't hurt!

The single biggest thing I fight as a compliance engineer is the lack of clear and sufficient communications. Poor writing techniques, to include grammar and choice of words, are the toughest of problems. I see this every day in every aspect of life, whether here in the compliance world, at home with communications from my children's schools, and in local politics. Having been a local elected official, I have seen the results of poorly written regulations allow some to do what they please, in spite of the desires of the community in general. When the regulations are made clear and precise, enforcement gets easier. But when the reason why is added to the regulation, there are many fewer attempts to get around them and less enforcement is required. So here is my vote for adding the whyfors to the whats in all of our standards. And I am not talking about adding pages here, just a simple clear concise sentence of the intent would be adequate.

This, unfortunately, is not part of a standard's format;-- however, it would be of great benefit ( I am changing subjects now!) if standards routinely identified the objective of every test, and sometimes even of requirements. What happens often is that due to either poor sentence structure or poor translations, the language is so garbled that it is not at all clear what the whole thing is all about. This then becomes an open field for a multitude of 'interpretations'. In majority of cases this could be avoided by clearly stating the objective and employing good writing techniques.

Norway uses the IT power distribution system; nothing wrong with that. But, not all Norwegian outlets include a ground contact. A few years ago, I was at NEMKO in Oslo for a meeting. The NEMKO main meeting room has two-wire outlets! (Their labs have grounding-type outlets.) When I lived in Spain, my NEW condo (1994) had BOTH grounding and two-wire outlets, depending on location. The outlets that were optimally positioned for lamps were two-wire; all of the rest were grounding. Unlike the USA, the two-wire outlets in both NEMKO and my condo accept grounding-type plugs. Two-wire outlets commonly exist in homes throughout the world. For this reason, our grounded products are also double-insulated. (The ground wire is for EMC purposes, not for safety purposes.)
