Industrial valves - Testing of valves - Part 1: Pressure tests, test procedures and acceptance criteria - Mandatory requirements
This standard specifies mandatory requirements for tests, test procedures and acceptance criteria for production testing of industrial valves.
The specified tests may also be used as type tests or acceptance tests.

Cette norme spécifie les prescriptions concernant les essais, les procédures d'essai et les criteres d'acceptation a remplir par chaque appareil de robinetterie. Les essais prescrits peuvent etre utilisés en tant qu'essais de type, essais en production ou essais d'acceptation. L'application de ces essais peut etre spécifiée dans les normes appropriées de produit ou de performance. Lorsque des prescriptions d'une norme de produit ou de performance different de celles données dans la présente norme, alors les prescriptions de la norme de produit ou de performance s'appliquent.

EN 12266-1:2003 (E)3ForewordThis document (EN 12266-1:2003) has been prepared by Technical Committee CEN/TC 69 "Industrial valves", thesecretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at thelatest by September 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.EN 12266 consists of two parts, which can be used separately under the general title, Industrial valves — Testing ofvalves:¾ Part 1 : Pressure tests, test procedures and acceptance criteria — Mandatory requirements¾ Part 2 : Tests, test procedures and acceptance criteria — Supplementary requirementsPart 1 was drawn up on the basis of International Standard ISO 5208 and Part 2 contains supplementary testingrequirements for tests, test procedures and acceptance criteria of valves.Special requirements, which are specific to one product or one performance standard only, are not included in thisstandard. Details should be included in the appropriate standard.Annex A forms a normative part of this part of EN 12266.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 12266-1:2003
EN 12266-1:2003 (E)4IntroductionThe purpose of this part of EN 12266 is to establish certain basic requirements for the production pressure testing ofindustrial valves in order to ensure uniform tests and test procedures are adopted.

The users of this standard should analyse thehazard resulting from the pressure and take proper safety precautions.A.1.2 Test equipmentThe test equipment shall be of such a design, that it does not subject the valve to externally applied loads whichmay affect the results of the test.NOTEThe test equipment can apply external loads sufficient to react to the forces resulting from the test pressure.When using test equipment and procedures different to that detailed in this standard, the manufacturer shall beable to demonstrate the equivalence of such test procedures and acceptance criteria with the requirements of thisstandard.A.1.3 Measuring equipmentThe measuring equipment shall be capable of measuring the fluid pressure with an accuracy of ± 5 % of therequired test pressure.A.1.4 Painted, coated or lined valvesValves shall not be externally painted or otherwise coated with materials capable of sealing against leakage fromexternal surfaces of the shell before the shell strength test, reference P10, and the shell tightness test,reference P11.Valves with liners, internal linings or internal coatings that form a design feature of the valve may be tested with theliner or after lining or coating.NOTEIf tests in the presence of a representative of the purchaser are specified, painted or coated valves from stock maybe retested without removal of painting or coating.A.1.5 Test fluidThe test fluid to be used, as specified in the relevant test procedures detailed in A.2.2.1, A.3.2.1 and A.4.2.1, shallbe :¾ either a liquid (water which may contain a corrosion inhibitor, or any other suitable liquid having a viscosity notgreater than water) ;¾ or a gas (air or other suitable gas).The test fluid temperature shall be between 5 °C and 40 °C.SIST EN 12266-1:2003
