Standard Specification for Rubber Insulating Matting
STANDARD published on 1.12.2022
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the acceptance testing of insulating rubber matting that are used as a floor covering for the personal protection of workers. The sheeting shall be made from any elastomer or combination of elastomeric compounds. Two types of matting, differing in chemical and physical characteristics, are provided and are designated as Type I, which has been properly vulcanized, and Type II, which has one or more of the following special properties: (A) ozone resistance; (B) flame resistance; and (C) oil resistance. Five classes of matting, designated as Classes 0, 1, 2, 3, and 4, are assigned according to electrical protection characteristics. When evaluated in accordance with the test procedures detailed herein, the matting shall adhere to the following property requirements: electrical properties such as phase-phase maximum use voltage, AC and DC proof-test voltages, AC and DC dielectric breakdown test voltages, and AC and DC electrode clearances; an physical and chemical properties such as moisture absorption, oil resistance, tensile strength, tension set, elongation, resistance to accelerated heat aging, and flame resistance.
