This part of ANSI/ISA-60079-29 specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of flammable gas or vapour concentrations with air. The apparatus, or parts thereof, are intended for use in explosive gas atmospheres and in mines susceptible to firedamp. The current edition standard ANSI/ISA-60079-29-1 (12.13.01)-2013 succeeds ANSI/ISA-12.13.01-2002 (IEC 61779-1 through 5 Mod) allowing for the use of the current edition or one previous edition to be valid for approval agency accreditation and product re-certification.
