The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I.It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II.
The original design was based on the 19 mm Becker cannon cartridge by the Coenders brothers at Stahlwerke Becker of Reinickendorf, Germany. [2] [3] Development commenced in 1913 and was therefore already advanced when the War Ministry issued a specification in June 1915 calling for an aircraft cannon of under 37 mm caliber and 70 kg weight capable of firing a 10-round burst.

The superficial Rockwell scales use lower loads and shallower impressions on brittle and very thin materials. The 45N scale employs a 45-kgf load on a diamond cone-shaped Brale indenter, and can be used on dense ceramics. The 15T scale employs a 15-kgf load on a 1 ⁄ 16-inch-diameter (1.588 mm) hardened steel ball, and can be used on sheet metal.
Their data has impact: a nurses' union's 2011 public statements cited Becker's data to justify their demands. [7] Becker's reports on how data is used (or abused) [8] and they cite, review and analyze [9] surveys and rankings, [10] including how various subgroups of medical practitioners are affected. [11]
