Safety and control devices for oil burners and oil-burning appliances — Particular requirements — Part 1: Automatic and semi-automatic valves

This document 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 document covers type testing only.
