5.2 Preparation of specimens
Unless otherwise specified, the specimens shall be provided in the “as manufactured” condition. Care shall be taken to ensure that no part of the surface to be tested becomes contaminated, particularly by contact with fingers, during the preparation and handling of the specimen.
Specimens shall be equipped with their normal accessories, mounted as specified in the detail product specification.
5.3 Wiring
Where wiring of test specimens is required, the detail product specification shall contain information suitable to comply with the selected methods of test.
If specimens are not delivered with wire conductors already assembled, the wire conductors shall be connected to the associated parts in accordance with the manufacturer’s instructions and using the manufacturer’s recommended tooling. If no specific manufacturer’s instructions are provided, then refer to IEC 60352 series, or related specifications.
5.4 Mounting of specimen
When mounting is required in a test, unless otherwise specified, the connectors shall be rigidly mounted on a metal plate, a printed board or to specified accessories, whichever is applicable, using the normal mounting method, fixing devices or panel cut-out as laid down in the detail product specification.
6 Test (description and instructions)
6.1 Tests and measurements
Unless otherwise specified, all tests shall be carried out under standard atmospheric conditions for tests and measurements (15 °C to 35 °C ambient temperature, 25 % to 75 % RH, 86 kPa to 106 kPa atmospheric pressure) as specified in IEC 60068-1.
The test shall be carried out with specimens in the “as manufactured condition” unless otherwise specified in the detail specification. In no case shall the contact parts be cleaned or otherwise prepared prior to test, unless explicitly required.
A test normally consists of the following:
a) pre-conditioning (where required)
before measurements are made, the test specimens shall be pre-conditioned under standard atmospheric conditions for testing, for a time as specified in the detail product specification;
b) initial measurement (where required)
before a test is made, initial measurements (usually serving as reference for subsequent test failure criteria) shall be done in accordance with the detail product specification;
c) tests
the specimens shall be subjected to environmental conditions, such as temperature, humidity, vibration, shock, etc., for a specified period of time according to the detail product specification.
In addition to environmental conditions, the specimens shall be subjected to the tests (e.g. mechanical operation tests, electrical overload tests, soldering tests, etc.) according to the relevant part(s) of lEG 60512 under test conditions and severity, as specified in the detail product specification;
d) recovery (where required)
after the conditioning period and before making the final measurement, the specimens shall be allowed to stabilize for a specified period or recovery time at ambient temperature and humidity, at which the measurements are to be made unless otherwise specified in the detail product specification;
e) final examination and measurements
after recovery time, the final measurement shall be performed in accordance with the detail product specification.
6.2 Test sequences
The test sequences are as described in the sectional or detail product specifications. The test numbers used in this document have no significance with respect to test sequence; they are given to identify a test for reference purposes. In order to avoid duplication and costly measurements, the sectional or detail product specification will also select and prescribe those measurements to be performed out of a list of measurements contained in the various test method documents.
6.3 Combined tests
Combined tests are specified. Additional combinations of tests shall be avoided, unless
essential to a specific application.
6.4 Dimensional measurements
Repetition of identical dimensional measurements shall be avoided unless required to prove that all aspects of manufacturing, tooling or processes are satisfactory (for example, parts produced from multi cavity tooling).IEC 60512-1 pdf download.
