I think it's an interesting question.
Coming back to the previous comment, certainly the regime of certification is one that's very important. If you see a mark, and you cannot have confidence that the mark actually means something in terms of the product's performance, then, of course, we have a problem.
When I go out and buy something.... For example CGSB, for any of you who do construction if you ever get vapour barriers, installing a vapour barrier in your home, the ten mil vapour barrier, you will see the CGSB logo on it. Of course these products are tested.
So manufacturers have their product and they bring their product voluntarily to have it certified by us. We have a process to certify it including product testing. We use laboratories to certify and to test these products to make sure the samples perform. This is how we build confidence.
In many of these cases we do two things. We have what we call qualification and certification. We have a whole series of products we qualify, and that means we're doing it internally with laboratories to evaluate the product. In certification we actually have an external group that's also a third party review and provides for a greater degree of validation, if you want to put it that way. We use that often in higher-risk areas. For example we have medical gloves, which we certify for obvious reasons.
The certification regime itself is a critical piece of confidence in the marketplace to make sure people are getting a product that meets the standard, and they understand there's a consistent process that is being used, and a fair and accurate process that is being used. That's the confidence part.
