Chapter 11 COMPLIANCE WITH STANDARDS
11.5 Compliance with UL Standards and Canadian Standards (cUL certification)
11.5.1 General
Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria
for inspections/investigations pertaining to fire/accident insurance in the USA. Later, these standards
were authorized as the official standards to protect operators, service personnel and the general
populace from fires and other accidents in the USA.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL
certified products are equivalent to those compliant with CSA Standards.
