The standard we manage is not enforced. It is referred to in a number of pieces of regulation.
I'll give two examples: pressure tubes for nuclear reactors and welds for pipelines. In one case the Canadian Nuclear Safety Commission, and in the other case the National Energy Board, mandates that technologists who perform non-destructive testing be certified under the CGSB standard. They have to provide proof that they are certified.
There is no enforcement per se of the standard at Natural Resources Canada. What we do is certify individuals, who then perform tests, and it is other regulations that refer to the CGSB standard as a requirement for certain activities.
