ISO 23553-1 specifies safety, constructional and performance requirements, and testing of safety shut-off devices, for liquid fuels.
ISO 23553-1 covers type testing only.
It applies to safety shut-off devices which: are designed as e.g. automatic valves or fast-closing devices; are used in combustion plants to interrupt the flow of liquid fuels with or without delay on closing and with or without delay on opening; are for use with fuel oils; form part of a device having other function(s), such as oil pumps — in this case the test methods apply to those parts or components of the device forming the safety shut-off device, i.e. those parts which are necessary for the closing function; have declared maximum working pressures up to and including 5 000 kPa, for use on burners or in appliances using liquid fuels; are directly or indirectly operated electrically or by mechanical or hydraulic means; and are fitted with or without closed-position indicator switches.
The methods of test given in ISO 23553-1 are intended for product type testing.
