Scope

1DV.1 DE Modification of Clause 1@ first paragraph to replace with the following: 1DV.1.1 This standard specifies the requirements for the design@ construction@ testing and marking of Ex Equipment and Ex Components with type of protection liquid immersion ??o?? intended for use in explosive gas atmospheres. Ex Equipment and Ex Components of type of protection liquid immersion ??o?? are either: ? Level of Protection ??ob?? (EPL ??Mb?? or ??Gb??) ? Level of Protection ??oc?? (EPL ??Gc??) For Level of Protection ??ob??@ this standard applies where the rated voltage does not exceed 11 kV r.m.s. a.c. or d.c. For Level of Protection ??oc??@ this standard applies where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c. NOTE Requirements for higher voltages are under consideration. 1DV.2 DR Modification of Clause 1@ fifth paragraph to replace with the following: 1DV.2.1 This standard supplements and modifies the general requirements of UL 60079-0 Where a requirement of this standard conflicts with a requirement of UL 60079-0@ the requirement of this standard takes precedence.
