A - the skull is made of pottery, looking at the crack pattern from the limited view we have it looks like stoneware but could have been one of a number of brittle ceramics., B - hitting helmet with a hammer is not the same as most crashes, C- that's not a cycle helmet.
Any more red herrings?

Sorry Linford, I've been painstakingly re-organising my belly-button fluff collection ... again ...Gone very quiet on this thread

A- Of course it is...it needs to be to give your POV any credence...can you support this assertion with anything more than a guess ?
B - We have been discussing the value of adequately constructed head protection ...who implied that the current offering is that ? ...not I

Most people just stare at their feet and mutter things like 'busted' or something similar FF
A spot of googling suggests ECE 22.05 uses a velocity of 7.5m^s-1 in its drop tests. That equates to 27kmh^-1 or about 17mph.
Has it ever been disputed that a Thudguard may prevent an head injury in a toddler?

The particular lid of mine which my mate tested was one of these http://sharp.direct.gov.uk/testsratings/hjc-hq1

I get the impression that you are more than a bit disappointed they don't make them on your size

I wasn't aware that you were asking it of me in particular.
Will have to wait as I'm off into town for a few jars...they ought to give them away in adult sizes at closing time

Not by me.
However do forgive me, I thought this was discussion about cycle helmets.
You've raised this bizarre red herring about Thudguards and toddlers in more threads than I care to remember and I still don't understand your point.
Maybe you could debate it on some child protection forum and stop boring us with it.
As I indicated upthread if there was helmet on the market that I thought was going to have any realistic value in protecting my bonce I'd buy it and wear it.
Part of my work is in international committees that write technical standards in another safety-critical sphere, so I know how to read a standard, and have enough engineering knowledge to relate it to cycle helmet standards and their ability to protect against the kind of off I'm likely to have on the road (or indeed off-road). To cut a very long story short cycle helmets are designed and tested to provide adequate energy absorbtion in low speed impacts..... so my own personal "risk-assessment" has me wearing a helmet on the MTB but not on the road.
Now before someone comes along and says the people who write the standards are industry insiders with a vested interest in keeping the standards weak...that is just not how standards get written. Yes you'll get a panel of senior engineers from competing companies together in one room, but to suggest they collude to keep standards weak? Forget it, it doesn't happen. I'm quite sure that if Bell or Specialized or Giro or MET suddenly came up with some new technology that gave us hugely more energy absorbtion with the same levels of ventilation as current high end helmets, you'd find them copying each other and writing tougher tests into the standards within a couple of years, so as to keep new entrants out of the market if they could.
Rhetorical question?
