Industrial valves - Testing of metallic valves - Part 2: Tests, test procedures and acceptance criteria - Supplementary requirements
This European Standard specifies supplementary requirements for tests, test procedures and acceptance criteria of industrial valves made of metallic materials.
The specified tests may be used as type tests, production tests or acceptance tests. The application of these tests is specified in the appropriate product or performance standards.
When specified as a normative reference in a valve product or performance standard, this European Standard should be considered in conjunction with given specific requirements of the valve product or performance standard. Where requirements in a product or performance standard differ from those given in this European Standard, the requirements of the product or performance standard apply.
NOTE For testing of industrial valves of thermoplastic materials, ISO 9393-1 and ISO 9393-2 apply.
Industriearmaturen - Prüfung von Armaturen aus Metall - Teil 2: Prüfungen, Prüfverfahren und Annahmekriterien - Ergänzende Anforderungen
Diese Europäische Norm legt zusätzliche Anforderungen an Prüfungen, Prüfverfahren und Annahmekriterien für Industriearmaturen aus metallischen Werkstoffen fest. Die festgelegten Prüfungen können als Typ-, fertigungsbegleitende oder Annahmeprüfungen angewendet werden. Die Anwendung dieser Prüfungen ist in den entsprechenden Produkt- oder Gebrauchstauglichkeits-normen festgelegt. Wenn diese Europäische Norm als normative Verweisung in einer Produkt- oder Gebrauchstauglichkeitsnorm für Armaturen aufgeführt ist, sollte sie im Zusammenhang mit den festgelegten spezifischen Anforderungen dieser Produkt- oder Gebrauchstauglichkeitsnorm betrachtet werden. Wenn sich die Anforderungen in einer Produkt- oder Gebrauchstauglichkeitsnorm von den in dieser Europäischen Norm festgelegten Anforderungen unterscheiden, dann gelten die Anforderungen der Produkt- oder Gebrauchstauglichkeitsnorm.

Robinetterie industrielle - Essais des appareils de robinetterie métalliques - Partie 2: Essais, modes opératoires d'essai et critères d'acceptation - Prescriptions complémentaires
La présente Norme européenne spécifie les prescriptions complémentaires pour des essais, des modes
opératoires d’essai et des critères d’acceptation pour la robinetterie industrielle faite de matériaux métalliques.
Les essais prescrits peuvent être effectués en production, en tant qu’essais de type ou essais de réception.
L’application de ces essais est prescrite par les normes de produit ou de performance appropriées.
Lorsque la présente Norme européenne est spécifiée en tant que référence normative dans une norme produit ou
de performance, elle doit être considérée conjointement aux prescriptions données de cette norme produit ou
de performance. Lorsque des prescriptions d’une norme produit ou de performance diffèrent de celles données
dans la présente Norme européenne, alors les prescriptions de la norme produit ou de performance
s’appliquent.
NOTE Pour les essais d'appareils de robinetterie industriels en matériaux thermoplastiques, l'ISO 9393-1 et
l'ISO 9393-2 s'appliquent.
Industrijski ventili - Preskušanje kovinskih ventilov - 2. del: Preskusi, postopki preskušanja in prevzemni pogoji - Dodatne zahteve
Ta evropski standard določa dodatne zahteve za preskuse, postopke preskušanja in prevzemne pogoje za industrijske ventile, izdelane iz kovinskih materialov. Predpisani preskusi se lahko uporabijo kot tipski preskusi, proizvodni preskusi ali prevzemni preskusi. Uporaba teh preskusov je opredeljena v ustreznih standardih za izdelek ali lastnosti. Kadar je ta evropski standard v standardu za izdelek ali lastnosti ventila naveden v okviru zvez z drugimi standardi, ga je treba upoštevati skupaj z danimi posebnimi zahtevami standarda za izdelek ali lastnosti ventila. Kadar se zahteve v standardu za izdelek ali lastnosti razlikujejo od zahtev iz tega evropskega standarda, se uporabljajo zahteve standarda za izdelek ali lastnosti.

Pressure tests – Test procedures and acceptance criteria A.1 General requirements A.1.1 Purpose These general requirements shall be applied to all the test procedures defined in Annex A. Safety aspects of valve testing are not covered in this European Standard. NOTE Users of this European Standard should analyse the hazard resulting from the pressure and take proper safety precautions. A.1.2 Test equipment The test equipment shall be of such a design that it does not subject the valve to externally applied loads which may affect the results of the test. NOTE The 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 European Standard, the manufacturer shall be able to demonstrate the equivalence of such test procedures and acceptance criteria with the requirements of this European Standard. A.1.3 Measuring equipment The measuring equipment shall be capable of measuring fluid pressure with an accuracy of ± 5 % of the required test pressure. A.1.4 Painted, coated or lined valves Valves with liners, internal linings or internal coatings forming a design feature of the valve may be tested with the liner, after lining or coating. Attention shall be given that the internal linings or internal coatings are not damaged by the test procedure. NOTE If tests in the presence of a representative of the purchaser are specified, painted or coated valves from stock may be retested without removal of painting or coating. A.1.5 Test fluid The test fluid to be used shall be: either a liquid (water which may contain a corrosion inhibitor, or any other suitable liquid having a viscosity not greater than water); or a gas (air or other suitable gas). Relevant detailed test procedures are specified in A.2.2.1 and A.3.2.1. The test fluid temperature shall be between 5 °C and 40 °C. SIST EN 12266-2:2012
