IEEE 309/N42.3:1999 (R2006)

Revision Standard - Inactive-Reserved.
Test procedures for Geiger-Mueller counters that are used for the detection of ionizing radiation are presented so that they have the same meaning to both manufacturers and users. Also included is information on bases (i.e., connections) for the counters.

Presents test procedures and standard bases for Geiger-Mueller counters so that test results will have the same meaning to all manufacturers and users. The inclusion of standard bases provides guidance and uniformity.
This is to be a revision of ANSI N42.3/IEEE 309 and will include within it also the material now in ANSI N42.5 on standard bases. The inclusion of the N42.5 material is the reason for including "Standard Bases" in that revised title. Upon issuance of this revised N42.5 should be withdrawn and that is the intent. The standard is nearly 30 years old and is in need of updating. Geiger-Mueller counters continue to be produced and used in quantity.
