This Q &A document has been prepared in response to questions raised by clients and other interested parties in regards to a variety of topics. QPS welcomes the opportunity to answer any additional questions clients may have.

  • Is product listing/certification in the U.S.A. and Canada mandatory by law?

    In the USA, electrical safety regulations pertaining to product approval include:

    • Workplace safety laws of the Occupational Safety and Health Administration (OSHA), and
    • Installation requirements specified in NFPA 70, the National Electrical Code (NEC), and the laws of individual municipalities

    OSHA’s Regulations referenced in Part 1910 of the CFR (29 CFR Part 1910) are United Sates law and stipulate that all equipment (used in the workplace) must be approved by a Nationally Recognized Testing Laboratory (NRTL).
    Similarly, as per Article 110.2 and 110.3 of the NEC, all electrical equipment must either be “approved” by the Authority Having Jurisdiction (AHJ) or “Listed”, or “Labeled” by a nationally accredited Certification Body.

    In Canada: Product safety is under the Jurisdiction of Provincial Governments. Provincial Regulations stipulate that “no person may manufacture, install, offer for sale, or otherwise dispose of electrical equipment unless the equipment in question displays a label or mark of a certification organization that is accredited by the Standards Council of Canada (SCC)…”
    It is worth noting the absence of any reference to UL (in the U.S. regulations) and CSA (in the Canadian regulations).

  • Can manufacturers choose which certification mark to use?

  • What does the QPS Certification Mark mean when displayed on a product?

  • Is the QPS Certification Mark equivalent to the UL and CSA Marks?

  • What is the difference between the UL, CSA, and QPS Certification Marks?

  • Given that UL and CSA develop standards in their respective countries, doesn’t this mean that manufacturers must use the UL and CSA marks?

  • Does QPS have different types of Certification Marks?

  • Do all local inspection Authority Having Jurisdiction (AHJs) accept the QPS Certification Marks and approval Labels?

  • Is Field Evaluation accepted by the AHJs as a form of product approval?
