Annex B (informative) Bibliography
Applicable in all fields of electronics where equipment and installations are required to conform to the 482.6 mm (19 in) equipment practice [based on IEEE P1101.1 (D1.0, 1997), 1 IEEE Std 1101.10-1996, IEC 60297-3 (1984-01) [B4]2, and IEC 60297-4 (1995-03) [B5]] for mounting in equipment in according to ANSI/EIA 310-D-1992 [B1] and IEC 60297-1 (1986-01) [B3] (see Figure 1). Standard covers subracks equipped with front mounted plug-in units in accordance with IEEE P1101.1 (D1.0, 1997) and IEEE Std 1101.10-1996, also provides for additional rear mounted plug-in units in the same subrack. Standard allows other suitable IEC connector-related dimensions to be added (see Annex A).
