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.
