REED SWITCHES –

Part 1-1: Generic specification – Quality assessment

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
IEC 62246-1-1 has been prepared by IEC Technical Committee 94: All-or-nothing electrical
relays.
This first edition cancels and replaces the first edition of IEC/PAS 62246-2-1 published in
2008. It is a technical revision.
This edition includes the following significant technical changes with respect to the previous
editions:
– inclusion of introduction;
– update of references, terms and definitions;
– renumbering of clauses to bring them into a more logical order;
– inclusion of the generic specifications for reed switches;
– update of typical applications.

procedures for reed switches where enhanced requirements for the verification of quality
assessment specification apply.
This standard describes sampling and test schedules for qualification approval procedures,
quality conformance inspection, formation of inspection lots and intervals between tests.
NOTE All type of reed switches exclude mercury reed switches.

This standard selects from IEC 62246-1:2011 and from other sources the appropriate test
procedures to be used in detail specifications derived from this specification.
Reed switch types are specified depending on characteristic values and tests.
NOTE Mercury wetted reed switches are not covered by this standard due to their possible environmental impact.
