This European Standard specifies requirements and test methods for joints between adjacent factory made pipe, and/or fitting and/or valve assemblies for buried hot water networks in accordance with EN 13941-1.

This European Standard specifies testing, inspection and marking for the type approval, initial inspection, periodic inspection, intermediate inspection and exceptional check of metallic tanks (shell and equipment) of fixed tanks (tank vehicles), demountable tanks, rail tank wagons, portable tanks and tank containers for the transport of dangerous goods. This European Standard is not applicable to battery-vehicles and battery-wagons comprising cylinders, tubes, pressure drums, bundles of cylinders and multiple element gas containers (MEGCs), independent of whether the elements are receptacles or tanks. It is essential that the requirements of the applicable regulations for the transport of dangerous goods prevail in all cases over those of this standard.

This European Standard specifies the safety, design, construction, and performance requirements and testing for electronic pressure and/or flow rate regulators for burners and appliances burning one or more gaseous fuels, hereafter referred to as ‘regulators’. This European Standard is applicable to: - regulators with declared maximum inlet pressures up to and including 500 kPa with nominal connection sizes up to and including DN 250; - regulators which use auxiliary energy; - regulators, which function by controlling a gas outlet pressure or a gas flow rate; - regulators with a modular structure approved as a unit; - regulators intended for gas appliances to be installed in the open air and exposed to the environment. This European Standard does not cover: - regulators connected directly to a gas distribution network or to a container that maintains a standard distribution pressure; - electronic fuel/air ratio controls (see EN 12067-2). NOTE EN 12067-2 is applicable to regulators being part of an electronic fuel/air ratio system.
