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;

This document specifies design, type testing, marking and manufacturing test and examination
requirements for ball valves used as:
a) closures of refillable transportable gas cylinders, pressure drums and tubes;
b) main valves for cylinder bundles;
c) valves for cargo transport units (e.g. trailers, battery vehicles and MEGCs);
which convey compressed gases, liquefied gases and dissolved gases.
NOTE 1 In the course of the document, the term "valve" is used with the meaning of "ball valve".
This document does not apply to:
•   oxidizing gases as defined in ISO 10156,
•   toxic gases (i.e. gases listed in ISO 10298 having an LC50 value ≤ 5 000 ppm) and
•   acetylene for single gas cylinders, pressure drums and tubes.
NOTE 2 The reason for the exclusion of oxidizing gases is that the use of ball valves as closures of high
pressure cylinders for oxidizing gases is known to lead to specific ignition hazards that cannot reasonably be mitigated through the ball valve design or type testing. Safety hazards concern both the ball valve itself and any downstream equipment.
This International document does not apply to ball valves for liquefied petroleum gas (LPG),
cryogenic equipment, portable fire extinguishers and cylinders for breathing apparatus.
