Electrical apparatus for the detection and measurement of flammable gases - Part 4: Performance requirements for group II apparatus indicating a volume fraction up to 100 % lower explosive limit
IEC 61779-4-1998 发布历史
1 This part of IEC 61779 specifies requirements for group II (as defined in part 1) portable, transportable and fixed apparatus for the detection and measurement of combustible gas or vapour concentrations with air. The apparatus, or parts thereof, may be installed or used in potentially explosive atmospheres, other than mines susceptible to firedamp (i.e. group I). The requirements and test methods applicable to the apparatus covered by this standard are specified in part 1. 2 This standard is restricted to apparatus intended for the detection and measurement of combustible gas or vapour concentrations with air up to 100 % lower explosive limit (LEL).
IEC 61779-4-1998由国际电工委员会 IX-IEC 发布于 1998-04，于 2007-08 废止。
IEC 61779-4-1998 在中国标准分类中归属于: N56 环境监测仪器及其成套装置，在国际标准分类中归属于: 13.320 报警和警告系统。
