This part of ISO/IEC 62990 specifies general requirements for design, function and performance, and describes the test methods that apply to portable, transportable, and fixed equipment for the detection and concentration measurement of toxic gases and vapours in workplace atmospheres and other industrial and commercial applications. This document is applicable to continuously sensing equipment whose primary purpose is to provide an indication, alarm and/or other output function the purpose of which is to indicate the presence of a toxic gas or vapour in the atmosphere and in some cases to initiate automatic or manual protective action(s). It is applicable to equipment in which the sensor generates an electrical signal when gas is present.Cross References:IEC 60068-2-6IEC 60079-0IEC 61000-6-3IEC 61000-4-29IEC 61326-1IEC 60529IEC 61000-6-4IEC 60079-29-1ISO 6145-4ISO 20581ISO 18158ISO 6145-9IEC 60079-29-2ISO 6145-10IEC 60079-29-3ISO 6145-1IEC 60050-351ISO 6145-6ISO 6145-5ISO 6145-7ISO/IEC Guide 98-3ISO 6145-2IEC 60079-29-4IEC 60050-426ISO 6142IEC 62990-1:2019All current amendments available at time of purchase are included with the purchase of this document.
