IEC 62990-2:2021 is a standard that provides guidelines for the selection, installation, use, and maintenance of gas detectors used to measure toxic gases and vapours in workplace environments. The purpose of these gas detectors is to ensure the safety of individuals and property by indicating the concentration of toxic gases and vapours and providing warnings of their presence.

The standard applies to electrical equipment that is designed to provide indications, alarms, or other outputs to warn of the presence of toxic gases or vapours in the atmosphere. It also covers equipment that can initiate automatic or manual protective actions in response to the detection of such gases.

The scope of the standard includes fixed, transportable, and portable equipment. It is intended to be used in conjunction with IEC 62990-1, which defines the types of equipment covered by the standard. However, the guidance provided in this document can also be relevant to equipment not specifically covered by IEC 62990-1.
