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.
International Standard IEC 62246-1-1 has been prepared by IEC technical committee 94: All-
or-nothing electrical relays.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
editions:
a) update of the scope, references and terms and definitions;
b) inclusion of guidelines for the preparation of blank detail and detail specifications;
c) update of characteristics values including functional ratings for safety;
d) update of the quality conformance inspection procedures;
e) update of typical applications.

INTRODUCTION
Reed switches which are in mass production and which are widely used, in practice could be
classified by the following characteristics:
a) Size:
• Normal or standard reed switches with a tube more than 50 mm in length and more
than 5 mm in diameter;
• Sub-miniature reed switches with a tube more than 20 mm and up to 50 mm in length
and up to 5 mm in diameter;
• Miniature reed switches with a tube more than 10 mm and up to 20 mm in length and
more than 2 mm and up to 5 mm in diameter;
• Micro-miniature reed switches with a tube up to 10 mm in length and up to 2 mm in
diameter.
b) Type of switching of electric circuit:
• Closing or normally open – A type or NO;
• Opening or normally closed – B type or NC;
• Changeover – C type or CO.
c) Withstand voltage level:
• Low-voltage (up to 1 000 V);
• High-voltage (more than 1 000 V).
d) Switches power:
• Low-power (up to 60 W or 60 VA);
• Power (100 W to 1 000 W or 100 VA to 1 000 VA);
• High-power (more than 1 000 W or 1 000 VA).
e) Types of electric contacts:
• The tube is filled with dry air, gas mixture, vacuumized, or high pressurized.
Based on the general provisions of IEC 62246-1:2015, this document selects and specifies
blank detail and detail specifications including safety contact ratings and test procedures for
reed switches where enhanced requirements for the verification of quality assessment
specification apply.
This document 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.

4 Test schedules
4.1 General
Test procedures of quality assessment are specified in Table 1 which is referenced in the
corresponding subclauses of IEC 62246-1.
4.2 Order of tests
Quality conformance inspection is divided into two parts: that carried out lot-by-lot, on which
the release of the individual lots is based, and that carried out on a periodic basis, which
contains the time-consuming and more expensive tests.
When several tests are subsequently to be carried out on any one specimen or number of
specimens, the following order shall apply, unless otherwise specified in the detail
specification:
a) a 100 % test with
b) tests in groups.
4.3 Test groups and subgroups
For the 100 % test subgroup, a reed switch shall be rejected when it fails any test. For
detection purposes, a contact can be considered closed when the voltage drop across it is
less than one half of its open-circuit value. Conditions of test shall be specified in the detail
specification.
4.4 Type test
• Sampling and test schedule are specified in Tables 2 and 3.
• The tests specified and their order is mandatory.
• Tests stated in Tables 2 and 3 are mandatory for the variants except when otherwise
specified.
4.5 Quality conformance inspection
An initial conformity test has to be passed and then confirmed by routine tests, lot-by-lot tests
and periodic tests.
Quality conformance inspection contains the tests stated in Table 4:
• Group A: routine tests;
• Groups A and B: lot-by-lot tests;
• Group C: periodic tests.
Unless otherwise stated in this document, all tests of Table 4 are mandatory.
Where a subgroup contains cumulative tests, the order of the tests is mandatory. Specimens
that have been subjected to tests denoted as destructive (D) shall not be released for delivery.
Specimens that have been subjected to tests denoted as non-destructive (ND) are permitted
to be released for delivery.
4.6 Formation of inspection lots
The basis for the determination of sample size for the quality conformance inspection is the
reed switch quantity produced during one month.

IEC 62246-1-1:2018 © IEC 2018 – 11 –
4.7 Periodic test
The periodic test shall be performed in regular intervals as specified by the manufacturer, as
a minimum with the rated operating current I only.
e
For each periodic test, the evaluated B10 value shall be at least 80 % of the B10 value
obtained from the conformity test.
Fixed sample sizes for group C inspection shall be taken from a lot (or lots) which has (have)
passed groups A and B inspection during or at the end of the specified reference period.
4.8 Periodic test intervals between tests
• Subgroup A0: at shipment.
• Subgroups A4 and B1: manufacturer specifies the intervals.
• Subgroups C1: at least once a year.
• Subgroup C4: at least once every two years.
4.9 Standard conditions for testing
If not otherwise stated, all tests shall be performed under standard conditions for testing
according to 6.3 of IEC 62246-1:2015.
4.10 Mounting of test specimens during the test
The following requirement shall apply for shock and vibration tests.
The reed switch shall be mounted by its normal mounting method to the test fixture, where
inherent resonances have been minimized so as not to invalidate the test.
4.11 General conditions for testing
