Currently, on many product labels, it is common to see UL certification on each product. Many people wonder what the UL standard is? How to check UL certification number? How does this standard affect the quality of goods? This standard is one of the most rigorous certifications and quality tests available today for products before they are released on the market.
What is the UL standard?
UL stands for the English phrase: Underwriters Laboratory or Organization for Cooperation between Laboratories, founded in 1894 with its headquarters located in Northbrook, Illinois, USA.
In addition, You can also meet the ULC logo with the same logo design, but with the addition of the letter “C”. ULC is a branch of UL, established for the Canadian market and currently only standardizes for fire protection and fire protection, other areas are still based on UL standards for testing. Most of LAWRENCE’s products meet both UL and ULC standards to supply the Canadian market.
Why should you buy UL certified products?
UL is a 3rd party testing organization licensed by the US government, their evaluation activities are not in the interest of the organization, nor for the financial benefit of the product. You can therefore trust that the certified product is completely unbiased, free from any influence on the part of the manufacturer.
Currently, almost all UL testing standards are based on their own standards, and additionally refer to American ANSI, ASTM, BHMA, etc. standards for evaluation. Thus, the UL standard is known as the most rigorous standard in the world.
For example: 1 set of steam pushers according to CE standard will have a fire resistance of 120 minutes with a life of 500,000 times, while a UL standard will have a fire resistance of 180 minutes, a mandatory life of up to 1,000,000 times ( ANSI & BHMA references).
