IRIS - International Railway Industry Standard Rev.02
IRIS - International Railway Industry Standard Rev.02 (2009)是軌道(車輛)產業的品質管理系統標準,一般稱為軌道產業的ISO 9001。相對應的功能安全標準為歐盟的EN 50129: Railway Applications - Communication, Signalling, and Processing Systems - Safety Related Electronic Systems For Signalling (如前所述,其上游標準就是IEC 61508)。(有關功能安全的說明,可參考 http://redi.org.tw/wiki/index.php/功能安全 )
