Dielectric gas - Wikipedia

A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges.Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc.Get price

Laser Standards and Classifications - RLI

ANSICDRHOshaIECThe “M” Classes **Comparison of ClassificationsThe American National Standards Institute (ANSI) is an organization for which expert volunteers participate on committees to set industry consensus standards in various fields. The ANSI Z136 Committee has published or has under development seven standards specific to the laser field. The current version of the main ANSI Z136.1 Standard (Z136.1-2000) assigns lasers into one of four broad hazard Classes (1, 2, 3a, 3b and 4) depending on the potential for causing biological damage. Classification is determined by calculations based on exposure time, laser wavelength and average power for CW or repetitively-pulsed lasers and total energy per pulse for pulsed lasers.(1) These calculations are used to determine a factor defined as the Accessible Emission Limit, or AEL which is the mathematical product of the Maximum Permissible Exposure limit (MPE) given in the Standard and an area factor computed from the defined term called the Limiting Aperture (LA). That is: AEL = MPE x Area of LA . L...Get price
