   For what it's worth, I worked for BSI from 1980 to 1996 testing (among
other things) cycle helmets. I was involved with the development of the
PAS (Product Approval Specification) that we used to Kitemark them
before the British Standard was finalised.

Feeling embarrassed about my previous reply now, but I'm curious: do
you know how the guidelines were designed. Basically, did somebody say
"this is how much protection a helmet needs to give, in order to be
worthwhile", or did somebody say "This is how much protection it's
reasonable to build into a helmet, so we'll use it as a basis for the
guidelines".

	There is always a bit of a need for a balance between drawing up the best possible specification and coming up with something that manufacturers can produce at a sensible cost... No point in having a specification that nobody works to. For that reason most British Standards are (or were in my day...) largely written around the best of the products that are available and then amended as the quality of materials and methods improve. The committee producing the standard had representatives from manufacturers as well as BSI, RoSPA, Department of Transport etc. Alan
