Gives the general principles of protection by artificial ventilation.
The International Electrotechnical Commission IEC series of explosive atmosphere standards covers a wide array of important considerations when it comes to potentially explosive atmospheres. It deals only with the risk of the 6079-2 becoming a source of ignition.
For Level of Protection “eb”, this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r. Back to Explosive Atmosphere Standards Home. This publication is published as a double logo standard.
Where a requirement of this standard conflicts with a requirement of IECthe requirements of this standard take precedence. This standard constitutes an extensive technical revision which supersedes BS EN Learn more about the cookies we use and how to change your settings.
While it does not preclude the use of other quality management systems that are compatible with the objectives of ISO In Clause 7 other general considerations for dust layers are described. Where a requirement of this standard conflicts with a requirement of IECthe requirements of this 6079-2 shall take precedence.

Artificial ventilation for the protection of analyser s houses Gives the general principles of protection by artificial ventilation. It does not e devices that operate by induction heating, skin effect heating or direct pipeline heating, nor those intended for stress relieving.
e This standard supplements and modifies the general requirements of IEC and the intrinsic safety standard IEC This edition includes the following significant changes, apart from a general review and updating of the first edition of IECharmonization with IEEE Std.
Values of chemical properties of materials are provided to assist in the selection of equipment to be used in hazardous areas. The requirements of this standard apply to both Levels of Protection unless otherwise stated. In addition as this Standard is now to become one of the IEC series, changes have been made to bring it more in line with others in the series by cross referencing.
