ISO/IEC 80079-20-2:2016 is a standard that provides test methods for identifying combustible dust and combustible dust layers. The purpose of these test methods is to allow for the classification of areas where combustible dusts are present, so that appropriate electrical and mechanical equipment can be selected and installed in these areas.

The standard specifies the atmospheric conditions for conducting these tests, including temperature (-20 °C to 60 °C), pressure (80 kPa to 110 kPa), and air with a normal oxygen content (typically 21% v/v).

It is important to note that the test methods described in this standard do not apply to recognized explosives, propellants, or substances that may behave similarly. The standard also does not cover dusts of explosives and propellants that do not require atmospheric oxygen for combustion, or pyrophoric substances.

This standard is considered a technical revision, as it replaces the first editions of IEC 61241-2-1, IEC 61241-2-2, and IEC 61241-2-3. The changes from the previous editions to this standard can be found in the foreword of the document.
