ISO 23551-2:2006 specifies safety, constructional and performance requirements for pressure regulators intended for use with gas burners and gas burning appliances. It also describes the test procedures for checking compliance with these requirements and provides information necessary for the purchaser and user.
ISO 23551-2:2006 applies to pressure regulators for gas burners and gas burning appliances of nominal connection size up to and including DN 250 that can be used and tested independently of these appliances. These regulators 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.
ISO 23551-2:2006 covers type testing only.
ISO 23551-2:2006 does not cover
