An acronym is a word that is formed from the first letters or parts of a series of words. For example, AIDS (acquired immune deficiency syndrome), radar (radio detecting and ranging), and scuba (self-contained underwater breathing apparatus) are common acronyms. 

All commercial diving work should be carried using equipment that is maintained as part of a planned maintenance system and suitable for the work in hand. While DWR 1997 does not exclude the use of Self Contained Underwater Breathing Apparatus (SCUBA), the need to provide communications between the diver and the surface as well the requirements for an independent air supply reserve tend to reduce the benefit of SCUBA and actively encourage the diving contractor to adopt a Surface Supplied Diving Equipment (SSDE) spread.

A typical nonthreaded non-pin-indexed yoke connection is shown in Fig. 8-2. The same format regarding connection number, rated pressure, gas assignment, and dimensional description that is provided for threaded connections is also used for these connections. Its primary use is in the self-contained underwater breathing apparatus (SCUBA) industry.

Connection CGA 950, the pin-indexed yoke connection, is the assigned standard for compressed breathing air in small-size medical cylinders at pressures up to 3000 psig (20 684 kPa). Connections CGA 850 and 855 (formerly CGA 1310) are assigned to SCUBA (self-contained underwater breathing apparatus) at pressures up to 3000 psig (20 684 kPa).
