This first edition of IEC cancels and replaces the second edition of IEC published in and constitutes a full technical revision. Electrical equipment whose normal operation involves sparks, arcing, or hot components and complex industrial standard equipment controllers whose protection type enables them 60079-2 be operated in hazardous areas. Such equipment measures the integral concentration of the absorbing gas over the optical path in units such as LFL meter for flammable gases.

The requirements for performance are 60097-2 IEC Protection of equipment and transmission systems using optical radiation Em The faster, easier way to work with standards.

It is intended that there should be a stronger link between Part 1 Construction and Part 2 Performance of this Standard by upgrading the reference in the Scope of part 1 from a note to a requirement.
