The American Occupational Safety and Health Administration (OSHA) drew up the OSHA Regulation. In Standard 29 CFR, the requirement for electrical installations or equipment stipulates that only installations or equipment which have been tested for the specified safety requirements by an NRTL (National Registered Test Laboratory) may be installed. The NRTLs specified include the following:
- Underwriters Laboratories (UL), with 3 different types of approval
- Factory Mutual (FM)
- Canadian Standarts Association (CSA).
Bürkert has been granted this approval and offers to serve as an agent for other companies. The complete CSA approval, from the measurements to be carried out up to preparation of the documents can be conducted by Bürkert.
