ANSI/ISA 60079-6 (12.00.05)-2009

This standard part of IEC 60079 specifies the requirements for the construction and testing of oilimmersedelectrical equipment, oil-immersed parts of electrical equipment and Ex components inthe type of protection oil immersion o, intended for use in explosive gas atmospheres.

NOTE Type of protection oil immersion o provides equipment protection level (EPL) Gb. For further information, seeAnnex A.

This standard supplements and modifies the general requirements of ANSI/ISA-60079-0IEC 60079-0. Where a requirement of this standard conflicts with a requirement of ANSI/ISA-60079-0 IEC 60079-0, the requirement of this standard takes precedence.

This standard is applicable to electrical equipment, parts of electrical equipment, and Excomponents which, in the absence of oil immersion, are not ignition capable in normal operationas determined by ANSI/ISA-60079-15 IEC 60079-15 or ANSI/ISA-60079-11 IEC 60079-11.
