SA/SNZ TS IEC 60079.42:2022同样采用了IEC TS 60079-42:2019，该标准为使用电气安全装置的设备制造商提供了指导，以降低潜在火源在爆炸性环境中防爆设备中生效的可能性。电气安全装置执行安全功能，以控制爆炸性环境中电气和非电气防爆设备的潜在火源。

SA/SNZ TS IEC 60079.42:2022 identically adopts IEC TS 60079-42:2019 which provides guidance for equipment manufacturers where electrical safety devices are used to reduce the likelihood of potential ignition sources becoming effective in Ex Equipment located in Explosive Atmospheres. Electrical safety devices perform a safety function to control potential ignition sources from both, electrical and non-electrical Ex Equipment in explosive atmospheres.
