GB/T 19520.21-2023 Mechanical structures for electrical and electronic equipment—Dimensions of mechanical structures of the 482.6 mm (19 in) series—Part 3-109:Dimensions of chassis for embedded computing devices
Abstract
This document specifies the dimensions and physical properties of the chassis and its printed circuit boards, thereby providing mechanical and environmental integrity for embedded computing devices. Embedded computing devices are used in various applications such as machine control, medical, transportation, aerospace, and communications, and they are typically based on single-board computers.
To facilitate the determination of suitable chassis and single-board dimensions, this document is based on a 44.45 mm (1.75 in) structural grid.
