UL 2085 Aboveground Storage Tanks (AST)
A UL 2085 tank is an aboveground, shop fabricated, secondarily contained vessel designed to store flammable and combustible liquids constructed according to Underwriters Laboratories Standard 2085. A UL 2085 tank is intended to limit the heat transferred to the primary tank during a fire and to protect the tank from physical damage.
UL 142 Tank
UL 142 tank is a welded steel vessel tank designed to store flammable and combustible liquids constructed according to Underwriters Laboratories Standard 142. A UL 142 tank is intended for noncorrosive, stable liquids that have a specific gravity not exceeding that of water.
What Are The Differences Between UL-142 And UL-2085 Standards?
There are a few key differences between UL-142 and UL-2085. At the core, UL-2085 rated tanks offer more protection. This protection may include double-walled tank designs and/or stronger carbon steel materials. Some UL-2085 tanks also feature inside containment walls or insulation from the outside walls. UL-205 tanks are able to withstanding fire through a two-hour liquid pool and furnace fire test. Tanks are also testing to determine that the tank is impact-resistant and resistant to projectiles (such as bullets). These more difficult standards provide a higher level of protection overall to meet higher specifications.
