According to Sira, 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 (Electrical apparatus
for the detection and measurement of
combustible or toxic gases or vapours or
of oxygen. Requirements on the
functional safety of fixed gas detection
systems) takes the general
requirements of IEC 61508 and
extends them by applying them
specifically to gas detection equipment.

Ultra-compact, IRmax is designed
to detect methane gas and other
potentially explosive hydrocarbons.
