It is identical to I

2、EC 60079-7:2015, incorporating amendment 1:2017. It supersedes BS EN 60079-7:2015, which is withdrawn. It partially supersedes BS EN 6007915:2010, specifically the requirements for Type of Protection “nA”.The significance of the changes between this standard and BS EN 60079-7:2007 (for “ec”), and be

3、tween this standard and BS EN 60079-15:2010 (for “nA”) are listed in a table in the IEC foreword.The start and finish of text introduced or altered by amendment is indicated in the text by tags. Tags indicating changes to IEC text carry the number of the IEC amendment. For example, text altered by I
