FprEN 88-2

Safety and control devices for gas burners and gas burning appliances - Part 2: Pressure regulators for inlet pressure above 50 kPa up to and including 500 kPa and associated safety devices FprEN 88-2

Scope

This European Standard specifies the safety, design, construction and performance requirements and testing for pneumatic pressure regulators and safety devices for burners and appliances burning one or more gaseous fuels, hereafter referred to as ‘pressure regulators’.
This European Standard is applicable to:
- pressure regulators with declared maximum inlet pressure above 50 kPa up to and including 500 kPa, of nominal connection size up to and including DN 250 for use with one or more fuel gases in accordance with EN 437;
- pressure regulators incorporating safety devices;
- pressure regulators which use auxiliary energy; and
- stand-alone pressure regulators or pressure regulators equipped with a control device for maximum or minimum gas pressure.
NOTE Stand-alone pressure regulators incorporating one function (i.e. regulation of the downstream pressure) are not covered by EN 126.
This European Standard is not applicable to:
- pressure regulators that are connected directly to mains pipe-work or to a container that maintains a standard distribution pressure;
- pressure regulators intended for gas appliances to be installed in the open air and exposed to the environment;
- safety devices which use auxiliary energy.
