The document outlines the Indian standard specification IS: 15652 for rubber insulating mats used in electrical environments, specifically designed to protect workers from electrical shocks in AC and DC installations with system voltages up to 66kV HT. It describes the mats' elastomeric composition and their application in front of high-voltage equipment for safety. The classification of safety mats is based on their voltage ratings and thickness, with three main classes defined.

1. InsulatingShock Safety Mats.
IS: 15652 is Indian Standard Specification for rubber insulating
mats for electrical purposes. It deals with insulating mats made
of elastomeric (that includes rubbers, latex and elastomeric
compounds that may be natural or synthetic or a mixture or a
combination of both) for use as floor covering for the
protection of workers on ac and dc installations with the
system voltages WS33KV HT up to BD 66kVHT. As standard
defines.
Specifically designed for use in front of high-voltage equipment
such as switchboards, electrical safety matting is a special
grade of rubber in mat form that has excellent insulating
properties. Providing safety for operators and maintenance staff
from electrical shock, it should be used in any area where the
health and safety risk assessment has shown possible exposure
to high-voltage shock.

2. VOLTAGE RATINGS

B 2.5 mm 11KV 22KV 45 KV
C 3.0 mm 33KV 36KV 65 KV
Classification: Safety Mats for Electrical Applications are divided in to
three main classes based on Voltage Ratings. Recommended division is
as follows:
