There are five categories of insulation used by the three different classes of equipment; functional, basic, supplementary, double and reinforced. Inorganic materials such as mica, glass fibers, asbestoswith high-temperature binders, or others with usable lifetime at this temperature. UL, the industry leader in standards development, is available to help you understand the requirements in this new standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
