17 Endurance
Replace the existing text by the following:
17.1 General requirements
17.1.1 Switches shall withstand without excessive wear or other harmful effect the
electrical, thermal and mechanical stresses that occur in normal use.
17.1.2 The sequence of tests to be completed on the same 3 specimens is as follows:
— TC3: a test at high speed specified in 17.5.3; this test only applies to switches with more than one pole, and where the type of connection is of polarity reversal;
— TC2: a test at slow speed specified in 17.5.2,
— TCI: an increased-voltage test at accelerated speed as specified in 17.5.1; this test does not apply to switches classified according to 7.2.9;
— TC9: a locked-rotor test as specified in 17.5.5 at accelerated speed; this test only applies to switches classified according to 7.2.9;
— TC4: a test at accelerated speed as specified in 17.5.4;
followed by the requirements of 17.6.
NOTE The different types of tests are specified in 17.5.
17.1.3 When required by Clause 13, the following test, TCIO, is conducted on a different set
of 3 specimens:
— TCIO: a test at very slow speed as specified in 17.5.6; this test only applies to switches according to the requirements of 13.1.
The manufacturer may choose to complete TCIO in the sequence of 17.1.2 in place of TC2.
Compliance is checked by 17.6.1 (TEl) and 17.6.3 (TE3).
17.2 Electrical endurance tests
The switch shall be loaded as specified in Table 102 and/or Table 103 and connected in accordance with the circuit as given in 61058-1:2016, Table 2.
a) Where, in IEC 61058-1:2016, Table 2, an auxiliary switch (A) is symbolized in the test
circuit, the tests for the two ON-positions of the specimen (S) are performed on two separate sets of test samples. The connection to the test load to be performed for the two tests is symbolized in IEC 61058-1:2016, Table 2 by an auxiliary switch A.AS NZS 61058.1.1 pdf download.
