All CB's are required to control their client's use of registration marks. At least some of them provide a set of guidelines. The guidelines can be lengthy as they include guidelines for each of the accreditation bodies that CB is associated with. They are also updated frequently as they are updated each time any of the accreditation bodies or ISO changes their rules.
Here are some general guidelines. You cannot use the ISO copyrighted logo (looks kind of like a globe with ISO across it). You cannot modify the ISO logo.
You cannot ever use any ISO terminology or other registration marks on the product or product packaging (this one is violated often).
You may use ISO terminology on letterhead, stationary, business cards, literature web site, etc. If you use the ISO terminology, you must use it entirely, not just parts of it. The correct terminology is "ISO 9001:2000 Certified", "ISO 9001:2000 Certification", "ISO 9001:2000 Registered" or "ISO 9001:2000 Registration" You may not use "ISO Certified" or "ISO 9001:2000" as those terms are incomplete.
Further, you can use the seals of any of the accreditation bodies that appear on your certification as well as the seal for your CB. You must follow the rules for each one as set out by them. The rules include such things as size, what must be used with it, colors that are acceptable, and so on.
It is no wonder that many registered companies choose not to use them.
