5 Tests
5.1 General remarks
5.1.1 General
As explained in the introduction, there are two test schedules which shall be applied according to the following conditions.
a) Press-In connections, according to the requirements in Clause 4 and the requirements in the manufacturers specification, shall be tested in accordance With the qualification test schedule in 5.3.2.
This test schedule is intended to be applied on individual press-in terminations without component housing.
b) Press-in connections which are part of a component and already qualified to the qualification test schedule shall be tested in accordance with the application test schedule In 5.3.4,
This test schedule is Intended to be applied on complete components consisting of multiple press-in terminations mounted in a component housing.
The application test schedule shall be implemented in the detail standard of the component in such a way that the duplication of tests may be avoided.
Therefore, the test phases in test group D (see 5.34.1) may be inserted in any test group of the component specification, as long as the sequence, conditioning and environment comply with the requirements of this standard.
5.1.2 Standard conditions for testing
5.1.2.1 General
Unless otherwise specified, all tests shall be carried out under standard conditions for testing as specified in IEC 60512-1.
The ambient temperature and the relative humidity at which the measurements are made shall be stated in the test report.
In case of dispute about test results, the test shall be repeated at one of the referee conditions of IEC 60068-1.
5.1.2.2 Precondltioning
Unless otherwise specified, the connections shall be preconditioned under standard conditions for testing in accordance with the requirements of IEC 60512.1 for a minimum period of 24 h.
5.1.2.3 Recovery
Unless otherwise specified, the specimens shall be allowed to recover under standard
conditions for testing for a period of a minimum of 2 h after conditioning.
5.1.3 MountIng of specimens
For the qualification test schedule, the sets of parts con5ist of press-in terminations and a test board with plated-through holes. When mounting is required in a test, the parts shall be mounted using the mounting method described in the manufacturer’s specification.
For the application test schedule, complete components shall be pressed on a printed board. using the normal mounting method, unless otherwise specified In the component specification or in the manufacturer’s specification.
NOTE For the defrnltlons of sets of parts end specimen, see .6 and 3.7.
5.2 Test and measuring methods
NOTE As far as test methods at. described in this subclsuse. it is inl.iid.d that the descnption be r.plac.d by a
reterence to IEC 60512 as soon as the relevant test method Is Included Wt IEC 60512.
5.2.1 General examination
5.2.1.1 Visual examination of parts and specimens
The test shall be carried out in accordance with IEC 60512, test Ia. Magnification shall be five times, and all parts and specimens shall be examined to ensure that the applicable requirements of 4.5 have been met.
5.2.1.2 ExamInation of dimensions
The test shall be carried out In accordance with IEC 60512, test lb. All parts shall be examined to ensure that the applicable requirements of 4.3 to 4.6 have been met.
5.2.1.3 Inspection of tools
The tools shall be inspected and controlled according to the manufacturer’s instructions and specifications to be sure that the applicable requirements of 4.2 and 4.6 have been met.
5.2.2 Mechanical tests
5.2.2.1 BendIng
This test us only applicable to press-in terminations having a free pvst length of 1O mm protruding from the board.
