This part of ISO 23553 specifies safety, constructional and performance requirements and testing of automatic and semi-automatic valves for oil. It applies to automatic and semi-automatic valves which are: – normally closed; – used in combustion plants to interrupt the oil flow with or without delay on closing; – for use with oil types (e. g. middle distillate fuel oil, crude oil, heavy fuel oil or kerosene) without gasoline; NOTE 1 For other oil types (e. g. oil emulsions), additional test methods can be agreed between the manufacturer and the test authority. NOTE 2 Oil types from petroleum refining processes are classified ISO-F-D in ISO 8216.99 and 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 automatic and semi-automatic valves, i.e. those parts which are necessary for the closing function; – for use on burners or in appliances using oil; – directly or indirectly operated, electrically or by mechanical or hydraulic means; – fitted with or without closed-position indicator switches. This part of ISO 23553 covers type testing only.
