UL LISTED PRODUCTS
Underwriters Laboratories (UL) is an independent, not-for-profit laboratory which tests products worldwide for safety. It awards certification to products that have passed their strict testing process. Over more than 100 years, UL has become the world’s best known independent product safety certification entity. Millions of products and their components are tested and verified by UL for conformity, quality, and reliability to meet their stringent standards.
The UL label on our products, such as the 236 Series for Acids and 436 Series for Alkalis is an assurance that those products have been tested and certified to the UL rigorous safety and performance requirements and then continue to undergo further inspections to ensure that production of the listed products maintains the high level of quality required to maintain the certification.
