IEC/TR 80002 Medical device software IEC/TR 80002-1:2009 Part 1: Guidance on the application of ISO 14971 to medical device software; ISO/TR 80002-2:2017 Part 2: Validation of software for medical device quality systems; IEC/TR 80002-3:2014 Part 3: Process reference model of medical device software life cycle processes
This vandal- and weather-resistant switch is used to request a traffic stop signal. Vandal-resistant switches (also referred to as vandal-proof switches) are electrical switches designed to be installed in a location (or device) and application where they may be subject to abuse and attempts to damage them, as in the case of pedestrian crossing switches.
IEC 61554 Panel-Mounted equipment – Electrical measuring instruments – Dimensions for panel mounting IEC 61557 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. – Equipment for testing, measuring or monitoring of protective measures
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.
Unlike ATEX which uses numbers to define the safety "Category" of equipment (namely 1, 2, and 3), the IEC continued to utilise the method used for defining the safe levels of intrinsic safety namely "a" for zone 0, "b" for zone 1 and "c" for zone 2 and apply this Equipment Level of Protection to all equipment for use in hazardous areas since ...
This part of IEC 61557 specifies requirements for insulation monitoring devices (IMD), which permanently monitor the insulation resistance R F to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1 500 V d.c. independent from the method of ...
IEC 62682 is a technical standard titled ... The standard was written as an extension of the existing ISA 18.2-2009 standard which utilized numerous industry alarm ...
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
