After the tests, the cord shall not have been longitudinally displaced by more than 2 mm, and theconductors shall not have moved over a distance of more than 1 mm in the terminals, nor shall there beappreciable strain at the connection.Creepage distances and clearances shall not be reduced below the value specified in 28.1.For the measurement of the longitudinal displacement, a mark is made on the cord while it is subjectedto the pull, at a distance of approximately 2 cm from the cord anchorage or other suitable point, beforestarting the tests.After the tests, the displacement of the mark on the cord in relation to the cord anchorage or other pointis measured while the cord is subjected to the pull.
