Actually, they don't 'Test' everything. The CSA stamp is in many cases self regulated, ie the manufacture pays CSA (big bucks!) and is allowed to uh, do their own due diligence.
I posted a comment here about a guy that blew the interior of his condo up* with a butane stove of some sort. OK; the backstory is that ALLEGEDLY he had just bought this butane sppliance from Crappy T...
Apparently this device has been recalled in Australia, US, and the UK. How come CSA and /or any other Federal agency hasn't pulled this thing off the market?
Just to be clear, CSA is a PRIVATE organization, according to a recent Legal decision, not a Gov't agency.
* The device started burning and the owner ran into the bathroom to get a towel to smother it. That's when the butane tank exploded! He was unhurt but the force of the blast moved the exterior condo wall outwards a full inch. Lots of water damage from the sprinkler system as well. The article in the local paper said that the device promoted itself as for indoor and outdoor use.
So. CSA? Their stamp and $2.50 will get you a coffee.
