A dielectric voltage withstand test (also known as a hipot test) is done by applying a voltage higher than operating voltage to the device or installation under test. In this test, the electric insulation of a product or installation is put under a voltage stress much higher than its normal operating voltage.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
IEC 60651 Sound level meters (Withdrawn, replaced by IEC 61672-1:2002 and IEC 61672-2:2003) IEC 60652 Loading tests on overhead line structures; IEC 60654 Industrial-process measurement and control equipment – Operating conditions; IEC 60657 Non-ionizing radiation hazards in the frequency range from 10 MHz to 300 000 MHz
An SIS performs a safety instrumented function (SIF).The SIS is credited with a certain measure of reliability depending on its safety integrity level (SIL).The required SIL is determined from a quantitative process hazard analysis (PHA), such as a Layers of Protection Analysis (LOPA).
The IEC developed their own standards in parallel with the IEEE, with IEC 60625-2-1993 (IEC 625). In 2004, the IEEE and IEC combined their respective standards into a "dual logo" IEEE/IEC standard IEC 60488-2-2004, Part 2: Codes, Formats, Protocols and Common Commands, [11] replaces IEEE 488.2-1992 and IEC 60625-2-1993.

Stack light in automated production for in-line quality inspection. Stack lights (also known as signal tower lights, indicator lights, andon lights, warning lights, industrial signal lights, or tower lights) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine's status to machine operators, technicians ...
