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.

The materials and the characteristics included in a table see Annex B have been selected with particular reference to the use of equipment in hazardous areas. Worldwide Standards We can source any standard from anywhere in the world. This seventh edition cancels and replaces the sixth edition, published in This is Part 2 of the European standard on explosive atmospheres. This standard does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself.
The application rn electrical equipment in atmospheres, which may contain explosive gas as well as combustible dust simultaneously, may require additional protective measures. Please download Chrome or Ne or view our browser tips.
