Part 1: Elastomeric seals
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 62339-1 has been prepared by subcommittee 65D: Analysing
equipment, of IEC technical committee 65: Industrial-process measurement and control.
This standard cancels and replaces IEC/PAS 62339-1 published in 2003. This first edition
constitutes a technical revision.
This bilingual version (2012-12) corresponds to the monolingual English version, published in
2006-12.
The text of this standard is based on the following documents:
FDIS Report on voting
65D/130/FDIS 65D/131/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

62339-1  IEC:2006 – 3 –
The French version of this standard has not been voted upon.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

MODULAR COMPONENT INTERFACES FOR SURFACE-MOUNT
FLUID DISTRIBUTION COMPONENTS –

Part 1: Elastomeric seals
1 Scope and object
This International Standard applies to all types of surface-mount fluid distribution components
with elastomeric sealing devices used within process analyser and sample-handling systems.
This includes components such as valves, filters, regulators, transducers, and controllers.
The scope of this standard is limited as follows.
a) This standard addresses only surface-mount fluid distribution components and proper
sealing methods. This standard is limited to sealing methods using elastomeric material
for the seals.
b) The designs of the actual system components and the flow substrate are not specified in
this standard. Any indication of mounting direction or other indexing is left to the
manufacturer as required for its equipment.
c) Users shall be aware that, on the basis of the stream conditions of their processes, other
technologies and components may be readily available.
d) This standard does not address the effects of various stream conditions on the technical
functionality of the component.
e) This standard does not address maintenance concerns for the components.
f) This standard does not refer to design issues pertaining to specific safety requirements.
These issues should be referenced to other standards, organizations, and recommended
guidelines.
g) International, national, and local codes, regulations, and laws should be consulted to
ensure that each component meets the user's regulatory requirements.
The object of this standard is to establish properties and physical dimensions that define the
interface for surface-mount fluid distribution components with elastomeric sealing devices
used within process analyser and sample-handling systems. The interface controls the
dimensions and location of the sealing surfaces to allow change of just one element of the
system without modification of the entire system. This is what makes the system modular from
both a design and a maintenance standpoint.
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.
ANSI/ISA-76.00.02:2002, Modular Component Interfaces for Surface-Mounted Fluid
Distribution Components – Part 1: Elastomeric seals
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

62339-1  IEC:2006 – 5 –
3.1
modular interface
boundary between an independently operable part of a flow system and the flow substrate to
which it is connected
3.2
surface finish
final surface specifications of the substrate block, interface plate, sealing grooves, and seal
devices
3.3
surface mount
arrangement of independent flow conditioning system modules upon a defined flow substrate
4 Ordering components with the modular interface
This standard may be used when specifying systems employing this modular component
design. It conveys the concept of the modular system and provides "footprint" dimensions to
permit inter-changeability of components.
Purchase specifications for components in accordance with this standard shall include the
standard number, date of issue, and references to the correct figure number.
5 Material requirements
5.1 Material certifications
Material certifications shall be obtained and shall include chemical analysis and mechanical
properties. For materials ordered to specifications that do not include mechanical properties,
the manufacturer shall specify minimum mechanical properties.
5.2 Bolt torque requirements
To ensure the performance of these systems, users are cautioned to adhere to bolt torque
requirements as specified by the manufacturer.
6 Sealing surface requirements
6.1 Surface roughness
The sealing surface (flat surface of the bottom of the mounting flange) shall have a maximum
surface roughness of 0,8 micrometers (32 micro-inches) Ra max in the area required for
sealing.
6.2 Surface condition
The sealing surface shall not have any radial scratches in the area required for sealing that
are visible to non-magnified normal vision.
6.3 Area required for sealing
The area required for sealing shall be defined as a surface with a diameter of 8,0 mm, with its
centre coincident with each required pressure connection.
