Safety related products undergo product certification to enable their use by the public. The value of testing by organizations without accreditation for product certification is based on faith in the organisation or its ethics, or culpability. In countries in which a national authority is a present (e.g., the United States), the listings provided by large well established third-party testing and certification companies are accepted as the societal standard. In such cases, the link to the building code is through regional standards, such as the Uniform Building Code, or the Standard Building Code.
