Documentation
After testing, the testing laboratory issues a test report to the manufacturer, who is not obliged to share it with anyone.
If the product passes the testing required for certification, the items in the test that passed are given a certification listing, which describes the product(s) that were tested, the application, and maximum and minimum tolerances for all components. Certification listings are short versions and interpretations of the test results.
A certification listing indicates that the test has been properly conducted, the tested systems passed, and that a follow-up agreement is in effect between the manufacturer or submitter and the certifier. This means that in addition to the original inspection where the test materials were produced, the certifier makes inspections of the manufacturing facility to ensure that what is being manufactured and sold is still the same as what was originally tested.
In the event that irregularities are discovered on the part of the manufacturer - substitutions of cheaper ingredients or components, deliberate irregularities, or an ingredient or component of a tested system which is no longer be available has been substituted - the listing can be de-activated and the manufacturer asked to remove all logos of the certifier from product literature, promotional materials, packaging, etc.
