CSA序言这是CAN/CSA-C22的第二版。2第60079-11号，爆炸性环境-第11部分:本质安全“i”的设备保护，这是采用相同名称的IEC（国际电工委员会）标准60079-11（第六版，2011-06），但有加拿大的偏差。它取代了2011年发布的前一版本CAN/CSA-C22。2第60079-11号（采用IEC 60079-11:2006）。它是CSA集团根据《加拿大电气规范》第二部分发布的一系列标准之一。 范围IEC 60079的本部分规定了爆炸性环境中使用的本安设备和相关设备的结构和测试，该设备用于连接进入此类环境的本安电路。此类保护适用于电路本身无法在周围爆炸性环境中引发爆炸的电气设备。本标准也适用于爆炸性环境外的电气设备或电气设备部件，或受IEC 60079中列出的其他类型保护的电气设备或电气设备部件- 爆炸性环境中电路的本质安全可能取决于此类电气设备或电气设备部件的设计和构造。通过应用本标准，对暴露在爆炸性环境中的电路在此类环境中的使用进行评估。本质安全系统的要求见IEC 60079-25。本标准补充和修改了IEC 60079-0的一般要求，表1中另有说明的除外。 如果本标准的要求与IEC 60079-0的要求冲突，应以本标准的要求为准。如果本标准中的要求适用于本安设备和相关设备，则本标准中使用术语“设备”。本标准仅适用于电气设备；因此，本标准中使用的术语“设备”始终指“电气设备”。如果相关设备放置在爆炸性环境中，应采用IEC 60079中列出的适当类型的保护装置进行保护- 0，则该保护方法的要求以及IEC 60079-0的相关部分也适用于相关设备。点击此处了解有关CSA培训计划的更多信息。

CSA PrefaceThis is the second edition of CAN/CSA-C22.2 No. 60079-11, Explosive atmospheres - Part 11: Equipment protection by intrinsic safety "i", which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60079-11 (sixth edition, 2011-06). It supersedes the previous edition published in 2011 as CAN/CSA-C22.2 No. 60079-11 (adopted IEC 60079-11:2006). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.ScopeThis part of IEC 60079 specifies the construction and testing of intrinsically safe apparatus intended for use in an explosive atmosphere and for associated apparatus, which is intended for connection to intrinsically safe circuits which enter such atmospheres. This type of protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. This standard is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IEC 60079-0, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits exposed to the explosive atmosphere are evaluated for use in such an atmosphere by applying this standard. The requirements for intrinsically safe systems are provided in IEC 60079-25. This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirements of this standard shall take precedence. If requirements in this standard are applicable to both intrinsically safe apparatus and associated apparatus the term "apparatus" is used throughout the standard. This standard is for electrical equipment only; therefore the term "equipment" used in the standard always means "electrical equipment". If associated apparatus is placed in the explosive atmosphere, it shall be protected by an appropriate Type of Protection listed in IEC 60079-0, and then the requirements of that method of protection together with the relevant parts of IEC 60079-0 also apply to the associated apparatus.Click hereto learn more about CSA training programs.
