Crenshaw’s in-house CSA Certified Manufacturer’s Testing Laboratory (ISO/IEC 17025:2005) is fully accredited by CSA under OSHA’s Nationally Recognized Testing Laboratory (NRTL) program to perform testing and listing onsite in our facility, and by Underwriters Laboratories to label for UL general coverage.
All lighting fixtures manufactured by Crenshaw are UL or CSA listed unless otherwise specified. All fixtures, listed or not, are built in compliance with UL1598 safety standards, and NEC codes. We go beyond UL and CSA requirements to test and verify that ballasts, drivers, and other components operate within their respective manufacturer warranty requirements for heat and other factors for maximum fixture life and performance. Through these and other rigorous manufacturing practices, Crenshaw maintains the highest quality and safety standards in the custom lighting industry.
Crenshaw fixtures are backed by our standard one-year manufacturer’s warranty, and a five-year electrical warranty. (Read more).
Nationally Recognized Testing Laboratory (NRTL) Program
In the 1970s, Underwriters Laboratories (UL) was replaced as the sole testing and certifying agency in the United States by the Nationally Recognized Testing Laboratory (NRTL) program under OSHA’s product safety mandate to allow for fair market competition among testing agencies. Currently, there are around a dozen NRTLs, but the most widely recognized is still UL. Underwriters Laboratories, together with the Association of Standardization and Certification (ANCE) and the Canadian Standards Association (CSA), is responsible for issuing the comprehensive safety standards for lighting manufacturers in the United States known as UL1598. It should be noted that as part of the anti-trust genesis for the NRTL program, civic agencies may not discriminate amongst NRTLs in issuing building permits and awarding contracts. Read more about the NRTL program at osha.gov.
Canadian Standards Association (CSA)
In the past decade, while Crenshaw continues to work with UL, we have established in-house testing and listing services under accreditation by CSA. UL’s good working relationship with CSA and CSA’s role as a collaborator in the issue of the UL1598 standards continue to satisfy our commitment to rigorous lab safety standards. CSA has proven responsive to the scheduling demands of custom lighting and is cost-sensitive. Both are major factors in the manufacture of custom lighting.
Crenshaw applies UL/US labels to certain specific fixture designs, and to all those fixtures which fall under UL general coverage for the U. S. and Canada. Both UL and CSA conduct quarterly inspections at our facility.
