Hi Peter:
I agree with you with your statement rather than address products, safety
standards need to address hazards. However, the hazard standards must be
made taking into consideration the environment in which the product is used

I feel that we are missing the point of Product Safety and trying to
over-simplify the issues (please read John Woodgate's excellent reply).

Hi Gregg:
Consider the number of PRODUCT standards written - these reflect the
accepted degree of protection (Operator or User) for each product under
specified operating conditions and accepted uses.
I invite consideration of INJURY, and the means by

You can find similar data by going through commercial aircraft test
procedures. I've seen the video from Boeing of chickens going through
turbine blades, cockpit deflections etc. Don't have a contact for you but

Hi John:
But the standards for these products have to be written by experts in
the design of these products - non-experts would not know the problems
that can arise. To produce generic safety standards, experts in the
design of ALL products would be required. These exist only on
Then, of course, there is the (apocryphal?) story of the Brits forgetting to
defrost the chickens in their tests... just goes to say that those dreally

I don't understand how testing to a different standard can make a product
safer. If there is a product specific standard, use it. If you are

I believe this information was officially released to the public, in joke

The original poster (KC CHAN [PDD] kcc...@hkpc.org) have not mention
about the frequency range of the intended measurements, nor even the
