This document specifies the production and performance relevant test requirements for automatic steam traps used for condensate removal/recovery services for optimized utilization of energy, in refinery, power generation or other general applications where steam is used as a medium of heat transfer.
The tests can be classified as production tests and performance characteristic tests and can be conducted to ensure the correct functioning of a steam trap or to evaluate the performance of a particular design. This document specifies the tests performed relative to each one of these two categories and briefly describes the corresponding test methods.

This document specifies fire type-testing requirements and a fire type-test method for soft- and metalseated isolation valves with one or more obturators. It is not applicable to the testing requirements for
valve actuators other than manually operated gearboxes or similar mechanisms when these form part
of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic or hydraulic)
can need special protection to operate in the environment considered in this valve test, and the fire
testing of such actuators is outside the scope of this document.
This document specifies the measurement and assessment criteria for:
a) through-seat leakage;
b) external leakage;
c) cavity overpressure relief of double-seated valves;
d) operability.
This document specifies the rules whereby the fire-type testing qualification for a valve can be extended
to untested sizes, pressure ratings and materials of construction of the same basic design type.
Fire test reports of valves tested according to previous editions of this document are acceptable when
submitted together with the full and compliant fire test report as per 6.7 of the edition under which it
was tested. Any data missing as required from 6.7 within the fire test report are accepted or rejected at
the purchaser’s discretion.
NOTE For the purposes of this document, the terms “fire type-test” and “fire test” are synonymous.

This document specifies requirements and acceptance criteria for type testing, in compliance with design conditions, of metallic butterfly and ball valves used for isolating services for all industrial applications, and serves to validate the product design over 205 cycles.
This document excludes testing for safety devices, control valves, thermoplastics valves, and valves for water supply for human consumption and sewage (e.g. the EN 1074 series).
This document defines the procedure for extending the qualification of the tested valve to untested sizes and pressure designations of the same product range.
The purpose of this type test is to validate the seat performance within manufacturer given pressure/temperature rating, provided by the manufacturer’s technical documentation of the product. This type test verifies torque requirements and the maximum allowable stem torque (MAST), as given in the manufacturer's technical documentation. This type test validates the durability of seat performance and operating torque through mechanical and thermal cycles.

This document specifies dimensions, materials and performance requirements (including methods of test) for expansion valves, of nominal sizes from DN 15 to DN 32, having working pressures ) from 0,1 MPa (l bar) to 1,0 MPa (10 bar).
Expansion valves are intended for fitting to the cold potable water supply of storage water heaters, having a maximum distribution temperature of 95 °C, for all energy sources.
Expansion valves do not control the temperature and alone do not constitute the protection required for storage water heaters. Expansion valves limit pressure, in the water heaters to what they are fitted, that is produced by thermal expansion of the water.
NOTE   The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

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 European Standard specifies the requirements for marking of industrial metallic valves. It defines the method of applying the markings, on the body, on a flange, on an identification plate or any other location.
When specified as a normative reference in a valve product or performance standard, this European Standard has to be considered in conjunction with the specified requirements of that valve product or performance standard.
The marking requirements for plastic valves are not within the scope of this European Standard.

The document specifies, dimensions, materials and performance requirements (including methods of test) for expansion groups, of nominal sizes from DN 15 to DN 25, having working pressures ) from 0,1 MPa (1 bar) to 1,0 MPa (10 bar).
Expansion groups shall be fitted to the cold potable water supply only for expansion purposes, e.g. of storage water heaters, having a maximum distribution temperature of 95 °C.
Expansion groups limit pressure in the water heater to which they are fitted, that is produced by thermal expansion of the water, prevent the backflow of water into the supply pipe and prevent the discharged water to get into contact with the water in the water heater.
Expansion groups do not control temperature and alone do not constitute the protection required for storage water heaters.
NOTE   The use of the device specified in this Standard does not override the need to use controls (e.g. thermostats and thermal cut-outs) which act directly on the power sources of water heaters.

Le présent document spécifie les exigences et les critères d’acceptation pour les essais de type, conformes aux conditions de conception, des robinets à tournant sphérique métalliques et robinets à papillon métalliques utilisés pour des services de sectionnement pour toutes les applications industrielles, et sert à valider la conception des produits sur 205 cycles. Le présent document exclut les essais de dispositifs de sécurité, de robinets de régulation, de robinets en matériaux thermoplastiques, et des robinets pour l’alimentation en eau destinée à la consommation humaine et en eaux usées (par exemple la série EN 1074). Le présent document définit la procédure permettant d’étendre la qualification de l’appareil de robinetterie soumis à l’essai à des désignations de dimensions et de pression non soumises à l’essai de la même gamme de produits. Cet essai de type a pour objet de valider la performance de siège pour la relation pression/température précisée par le fabricant, qui figure dans la documentation technique du produit donnée par le fabricant. Cet essai de type vérifie les exigences de couple et le couple de manœuvre maximale admissible (MAST), tels que donnés dans la documentation technique du fabricant. Cet essai de type valide la durabilité de la performance de siège et le couple de manœuvre grâce à des cycles mécaniques et thermiques.
