The magnetic properties of electrical steel are tested using the internationally standard Epstein frame method. [18] The size of magnetic domains in sheet electrical steel can be reduced by scribing the surface of the sheet with a laser, or mechanically. This greatly reduces the hysteresis losses in the assembled core. [19]
The Canadian Electrical Code, CE Code, or CSA C22.1 is a standard published by the Canadian Standards Association pertaining to the installation and maintenance of electrical equipment in Canada. The first edition of the Canadian Electrical Code was published in 1927. [1] The current (26th) edition was published in March of 2024.

The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron ...
