Description / Abstract:
These requirements cover electric heating pads for use in
accordance with the National Electrical Code on either
direct-current or single-phase alternating-current nominal 120 V
supply circuits.
Pads are made in a variety of shapes and sizes for direct or
indirect application to persons. A pad of unusual size or odd shape
is to be judged on its compliance with the requirements in this
standard and on further examination and tests to determine its
acceptability for the intended use and possible misuses.
