scope:
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 designed as fast-closing devices;
- are used in combustion plants to interrupt the flow of oil with or without delay on closing and with or without delay on opening;
- are for use with oil types (e. g. diesel, 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.
- from 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;
- are for use on burners or in appliances using oil; NOTE 2 - There is a need for applications above 5 000 kPa in the market.
- are directly or indirectly operated electrically or by mechanical or hydraulic means;
- are fitted with or without closed-position indicator switches. This ISO standard covers type testing only.
