Meets SIL 2

Crowcon's IRmax infrared hydrocarbon gas detector has been certified to SIL 2 by Sira Test and Certification according to the requirements of the IEC 61508 and EN50402 functional safety standards. This certification provides 3rd party assurance of the integrity and dependability of the IRmax and allows it to be included as part of a SIL 2 safety system. Sira says the IEC 61508 functional safety standard "provides the assurance that the safety-related systems will offer the necessary risk reduction required to achieve safety for the equipment".

The EN50402 takes the general requirements of IEC 61508 and extends them by applying them specifically to gas detection equipment.
