FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
The formal decisions or agreements of the IEC on technical matters, express as nearly as possible, an
2)
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the
form of standards, technical repo rts or guides and they are accepted by the National Committees in that
sense.
rnational unification, IEC National Committees undertake to apply IEC International
4) In order to promote inte
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
Attention is drawn to the possibility that some of the elements of this International Standard may be the
6)
subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 512-12-6 has been prepared by sub-committee 48B: Connectors, of
IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
The text of this standard is based on the following documents:
on voting
FDIS Report
48B/464/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.

Part 12: Soldering tests —
Section 6: Test 12f — Sealing against flux and cleaning solvents
in machine soldering
1 Scope and object
This section of IEC 512-12, when required by the detail specification, is to be used for testing
electromechanical components within the scope of technical committee 48*. This test may also
be used for similar components when specified in a detail specification.
The object of this test is to detail a standard test method to verify the effectiveness of the
sealing of a component against flux and cleaning solvents during the machine soldering
process. The results of this test may not be representative for other fluxes; e.g. resin-reduced
foam flux, other fluxing and cleaning methods as prescribed herein.
