IEC/TR 62685:2010 provides information about the assessment aspects of safe communication such as test beds, proof of increased interference immunity (EMC for functional safety), electrical safety, and other environmental requirements. It is only applicable to safety devices for functional safety communication which are developed according to IEC 61508 and IEC 61784-3 and covers general industrial environments such as defined in IEC 61131-2 or IEC 61000-6-2 and process automation environments such as those covered in the IEC 61326 series. Reference is made to the ERS (Equipment Requirements Specification) and/or SRS (Safety Requirements Specification) of a particular safety application to verify the necessary immunity of devices and systems according to IEC 61508. This bilingual version (2013-04) corresponds to the monolingual English version, published in 2010-12.
