Foreword
This document EN 12266-2:2002 has been prepared by Technical Committee CEN /TC 69 "Industrial valves", the
secretariat 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 or
by endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest by
May 2003.
EN 12266 consists of two parts, which can be used separately under the general title, Industrial valves — Testing
of valves :
Part 1: Pressure tests, test procedures and acceptance criteria — Mandatory requirements
Part 2: Tests, test procedures and acceptance criteria — Supplementary requirements
Part 1 was drawn up on the basis of International Standard ISO 5208 and Part 2 contains supplementary testing
requirements 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 this
standard. Details should be included in the appropriate standard.
Annexes A and B are normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.

Introduction
The purpose of this European Standard is to establish certain basic requirements for supplementary testing of
industrial valves in order to ensure uniform tests and test procedures are adopted. The tests and procedures
detailed may be used for production tests and also, when required, for type tests and acceptance tests.
1 Scope
This European Standard specifies supplementary requirements for tests, test procedures and acceptance criteria of
industrial valves.
The specified tests may be used as type tests, production tests or acceptance tests. The application of these tests
will be specified in the appropriate product or performance standards.
When specified as a normative reference in a valve product or performance standard, it is essential to consider this
standard in conjunction with the specific requirements of that valve product or performance standard. Where
requirements in a product or performance standard differ from those given in this standard, the requirements of the
product or performance standard apply.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

Annex A
(normative)
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 this annex.
Safety aspects of valve testing are not covered in this standard. The users of this 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 standard, the manufacturer shall be able
to demonstrate the equivalence of such test procedures and acceptance criteria with the requirements of this
standard.
A.1.3 Measuring equipment
The measuring equipment shall be capable of measuring the 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 that form a design feature of the valve may be tested with the
liner or after lining or coating.
If tests in the presence of a representative of the purchaser are specified, valves from stock can be retested.
A.1.5 Test fluid
The test fluid to be used, as specified in the relevant test procedures detailed in A.2.2.1 and A.3.2.1, 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).
The test fluid temperature shall be between 5 °C and 40 °C.
A.1.6 Test pressure
The test pressure shall be calculated based on the allowable pressure at room temperaturep . For valves for
s/RT
which the allowable pressure p is given only for an elevated temperature t, the allowable pressure at room
