FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60534-4 has been prepared by subcommittee 65B: Devices, of IEC
technical committee 65: Industrial-process measurement and control.
This third edition cancels and replaces the second edition published in 1999 and constitutes a
technical revision. The main changes with respect to the previous edition are listed below.
This standard has been revised to:
a) clarify the reading of the requirements;
b) introduce the measurement of leakage class V with air;
c) delete the inspection requirements as they are of a contractual nature.

INDUSTRIAL-PROCESS CONTROL VALVES –
Part 4: Inspection and routine testing
1 Scope
This part of IEC 60534 specifies the requirements for the inspection and routine testing of
control valves manufactured in conformity with the other parts of IEC 60534.
This standard is applicable to valves with pressure ratings not exceeding Class 2500. The
requirements for actuators apply only to pneumatic actuators.
This standard does not apply to the types of control valves where radioactive service, fire
safety testing, or other hazardous service conditions are encountered. If a standard for
hazardous service conflicts with the requirements of this standard, the standard for hazardous
service should take precedence.
NOTE This standard can be extended to higher pressure ratings by agreement between purchaser and
manufacturer.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

procedures for evaluating performance
3 Terms and definitions
For the purposes of this document, the following definitions, as well as those given in
IEC 60534-1 and other parts of IEC 60534, apply.
3.1
bench range
range of pressures to the actuator within which the nominal travel is performed in both
directions, with no pressure in the valve, but including friction forces
NOTE The actuator operating range, i.e. when the valve is installed under actual process conditions, will be
different from the bench range.
3.2
dead band
finite range of values within which reversal of the input variable does not produce any
noticeable change in the output variable (see Figure 1)

of the purchase order. The products inspected and tested need not necessarily be the
products actually supplied
3.7
actual inspection and testing
inspection and testing carried out, before delivery, according to the technical requirements of
the purchase order, on the products to be supplied or on test units of which the product
supplied is part, in order to verify whether these products comply with the requirements of the
purchase order
4 Requirements
Each valve shall be submitted to the mandatory tests specified in Table 1.
Supplementary tests given are subject to agreement between manufacturer and purchaser.

NOTE 1 The results of tests of a valve under static conditions in a factory generally do not correspond to
performance under working conditions. This standard is intended only to provide guidance for negotiations between
manufacturer and purchaser relative to tests of a specific valve.
4.1 Hydrostatic test
All control valve assemblies, excluding welded on fittings (see 5.4.5), with or without the
actuator fitted, shall be subject to a hydrostatic test at the pressure stated in 5.4.
4.2 Seat leakage test
The manufacturer shall advise the minimum achievable leak rate.
Leakage shall be specified by the following code :
X X X
↓ ↓ ↓
Leakage class Test fluid Test procedure
as shown in Table 3: G: air or nitrogen 1 or 2
I to VI L: water
---------------------- Page: 12 ----------------------
60534-4 IEC:2006 – 17 –
Example: III L 1
The seat leakage test as described in 5.5 shall be performed on each valve
These seat leakage provisions do not apply to control valves with rated flow coefficients less
than the following:
K = 0,086; C = 0,1
v v
Class VI is intended to apply to resilient seated valves only.
NOTE This part of the standard cannot be used as a basis for predicting leakage when the control valve is
installed under actual operating conditions.
4.3 Packing test
This test as described in 5.6 applies to the main valve packing, secondary packing of bellows
is excluded from this test.
4.4 Rated valve travel test
Travel adjustment of control valves shall be verified by test in the factory as described in 5.7
4.5 Dead band tests
The purpose of the dead band test is to measure the change in operating signal required to
produce a reversal of stem (or shaft) movement at approximately 25 %, 50 % and 75 % of the
rated travel of the valve actuator. This test as described in 5.8 may be performed on the valve
and actuator assembly (with or without positioner) or the actuator only (with or without
positioner).
4.6 Additional tests
Additional tests such as flow capacity, flow characteristic, stroking time, hysteresis, etc.
(which are outside the scope of this standard), if required, shall be the subject of agreement
between manufacturer and purchaser.
