d) clarification on conductor types with reference to classes defined in IEC 60228.

IEC 60352-5:2020 is applicable to solderless press-in connections for use in electrical and electronic equipment and components.
The press-in connection consists of a termination having a suitable press-in zone which is inserted into a hole of a board.
Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under specified environmental conditions.
The object of this document is to determine the suitability of press-in connections under mechanical, electrical and atmospheric conditions as specified by the manufacturer of the press-in termination and to provide a means of comparing test results when the tools used to make the connections are of different designs or manufacture.
This fifth edition cancels and replaces the fourth edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
a) revising the scope by removing the wording "… telecommunication equipment and in electronic devices employing similar techniques" and replacing it by "… electrical and electronic equipment and components" in the first paragraph;
b) adding terms and definitions for 'board', 'hole' and 'metal board' to recognize that press-in terminations are being used in many non-printed board materials;
c) editorial changes to clarify the difference between the two test schedules for qualification and application;
d) modification of upper limit of copper thickness of the plated-through-hole to reflect actual market trends and manufacturing practices;
e) removal of bending test, as this test is very specific for applications of press-in technology no longer common;
f) adding graphs to document the press-in and push-out force, since this is common testing practice and provides further insight into mechanical performance of the contact zone;
g) reducing the number of test specimens required, since in previous testing scheme a lot of test samples were discarded;
h) new wording in 4.5 for cracked and bent terminations;
i) added Figure 7b to show V and A connection locations when the press-in termination does not protrude through the bottom side of the board.

IEC 60352-4:2020 is applicable to non-accessible ID connections for which the tests and measurements according to Clauses 6 through 8 are suitable and which are made with:
– appropriately designed ID terminations;
– wires having solid round conductors of 0,25 mm to 3,6 mm nominal diameter;
– wires having stranded conductors of 0,05 mm2 to 10 mm2 cross-sectional area;
for use in electrical and electronic equipment and components.
Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions.
There are different designs and materials for ID terminations in use. For this reason, only fundamental parameters of the termination are specified, while the performance requirements of the wire and the complete connection are specified in full detail.
The purpose of this document is:
– to determine the suitability of non-accessible ID connections under specified mechanical, electrical and atmospheric conditions;
– to provide a means of comparing test results when the tools used to make the connections, if any, are of different designs or manufacture.
This second edition cancels and replaces the first edition, published in 1994, and its Amendment 1 (2000). This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Transferred Clauses 9 to 13 into Annex A (informative).
b) The figures were re-drawn for clarity.

IEC 60352-5:2012 is applicable to solderless press-in connections for use in telecommunication equipment and in electronic devices employing similar techniques. The press-in connection consists of a termination having a suitable press-in zone which is inserted into a plated-through hole of a double-sided or multilayer printed board. Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this part of IEC 60352 is to determine the suitability of press-in connections under mechanical, electrical and atmospheric conditions as specified by the manufacturer of the press-in termination and to provide a means of comparing test results when the tools used to make the connections are of different designs or manufacture. This fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- enhancement of Annex A and further application remarks are added;
- editorial changes throughout the standard to prevent the document from being misunderstood as specification for establishing press-in connection in total;
- deletion of all tables with hole dimensions. Historically the hole dimensions were constrained because of the dimensions of the wire wrap and clip connections posts. Since these connection technologies are no longer commonly used, the design requirements are no longer practical;
- inclusion of additional figures and one table in 4.4.4 to define tolerance ranges for holes in test-boards and to illustrate them;
- inclusion of a requirement for the thickness of the test-board in 4.4. The contents of the corrigendum of September 2014 have been included in this copy.
