Electrical safety standards The manufacturers of electronic tools must be taken into account with a several standard for electronic safety and protect the health of the humans and animals. potentially hazardous electromagnetic radiation at microwave frequencies. Few standard were introduced for the harmful impact from high frequency, CB-02 Radio Equipment Radiated Power Generated from Dammam Radio Stations,"1998 Electrical safety standards Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, electric arc, electromagnetic field and static electricity. The electrical safety develops with the technical progress. In 1989 OSHA promulgated a much-needed
Manganin Manganin Manganin is a trademarked name for an alloy of typically 84% copper, 12% manganese, and 4% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887). Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin wire is also used as an electrical conductor in cryogenic systems, minimizing heat transfer between points which need electrical connections.
