Overview

This standard contains general requirements for the construction, testing and performance requirements and describes the test method for portable, transportable and stationary electrical apparatus for the measurement of oxygen concentrations of gas mixtures with a measurement range of up to 25 % (V/V). The apparatus or parts thereof can be used in potentially explosive atmospheres (see 4.1) and in mines with potential danger of firedamp. The responsible Committee is UK 966.1 "Mess- und Warngeräte für gefährliche Gase" ("Measurement and warning devices for dangerous gases") of the DKE (German Commission for Electrical, Electronic and Informational Technologies) at DIN and VDE.
