BS EN 60297-3-109:2016

This standard BS EN 60297-3-109:2016 Mechanical structures for electrical and electronic equipment. Dimensions of mechanical structures of the 482,6 mm (19 in) series is classified in these ICS categories:

• 29.160.01 Rotating machinery in general
• 31.240 Mechanical structures for electronic equipment

This part of IEC 60297 specifies dimensions and physical properties of chassis and associated printed boards in order to provide mechanical and environmental integrity for embedded computing devices. They are used in various applications such as machine control, medical, transportation, aerospace and telecommunication, typically based on single board computers.

For the easy definition of the suitable chassis and associated single board dimensions, this standard is based on a structural grid of 44,45 mm (1,75 in).
