Description / Abstract:
This part of ISO 23551 specifies safety, constructional, and
performance requirements for thermoelectric flame supervision
controls, energized by a thermocouple, intended for use with gas
burners and gasburning appliances, hereafter referred to as
"controls".
This part of ISO 23551 applies to thermoelectric flame
supervision controls for gas burners and gasburning appliances of
nominal connection size up to, and including DN 50, that can be
used and tested independently of these appliances.
These thermoelectric flame supervision controls are suitable for
fuel gases, such as natural gas, manufactured gas, or liquefied
petroleum gas (LPG) at inlet pressures up to and including 50
kPa.
This International Standard covers type testing only.
This International Standard is not applicable to
a) the thermocouple and
b) controls which use auxiliary energy (e.g. electrical energy
supplied externally).
