The CUL mark is the UL mark used to circulate products in the Canadian market. Products with this logo have been certified in accordance with Canadian safety standards, which are basically the same as those quoted in the United States, and, of course, the standards for certain products are also different from those in the United States of America (UL). For example, hand-held power tools come with two sets of standards: UL45 only in the United states. UL745-1 applies to the United States and canada. The two standards are similar to those derived from the IEC IEC60745-- safety standards for hand held motor drive tools. CUL signs are widely used in household appliances, computer equipment, ventilation equipment, household anti-theft systems and other types of products.
Enterprises may meet Canadian customers in export and require products to have CUL certification. After CUL certification, the product meets the safety requirements of all provinces in canada. In the application of UL and apply for CUL has an advantage, because a lot of testing items of UL and CUL is repeated, so for CUL only a few less, and more than one application, it can lower the cost, in a relatively short period of time to obtain a bilateral authentication.
