An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
The association actively furthers their mission to serve the electrical industry by continuing to develop standards, most recently in 2015 with the publication of the ANSI/NETA Standard for Electrical Commissioning Specifications. NETA celebrated 45 years of continual improvement of the electrical testing industry in 2017.
This step-by-step guide explains how to apply and meet the NESC rules for electrical supply stations and equipment, as well as overhead and underground electric supply and communications lines. The 2023 NESC Course Program is a series of online courses that take an in-depth look at the rules, regulations, and changes made in the 2023 NESC ...
The Hawkins Electrical Guide was a technical engineering book written by Nehemiah Hawkins, first published in 1914, intended to explain the highly complex principles of the new technology of electricity in a way that could be understood by the common man.

ISO 16750, Road vehicles – Environmental conditions and testing for electrical and electronic equipment, is a series of ISO standards which provide guidance regarding environmental conditions commonly encountered by electrical and electronic systems installed in automobiles and specify requirements and tests.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
In electrical safety testing, portable appliance testing (PAT, PAT inspection or PAT testing) is a process by which electrical appliances are routinely checked for safety, commonly used in the United Kingdom, Ireland, New Zealand and Australia. The formal term for the process is "in-service inspection & testing of electrical equipment".
