This test is used to examine the adhesion between the compound and other elements of the cable. NOTE The test method does not apply to filling compounds with a dro

29、p-point higher than 80 C. 4.2 Apparatus For the purpose of this test, the different equipment used is as follows: a) strips of lead alloy of dimensions 170 mm 14 mm 0,9 mm; b) sheet brass pattern of dimensions 160 mm 160 mm 1 mm having a rectangular opening of 100 mm 10 mm and a locating edge to avo

30、id movement on the strips; c) metal mandrel having a 10 mm diameter; d) cold enclosure for 10 C 1 C. 4.3 Sample and test pieces preparation From a sample of finished cable take the filling compound to be tested. Ten test pieces shall be prepared with this compound as described below. Each strip of l

31、ead alloy shall be cleaned with a wire brush and laid on a plain base. BS EN 60811-411:201260811-411 IEC:2012 7 The pattern is placed on the strip so that the longitudinal edges of the strip are covered symmetrically. The compound to be tested is spatulated at ambient temperature into the opening of

32、 the pattern, and excess material shall be removed by a warmed spatula or other suitable device. The pattern is then removed from the strip. 4.4 Ageing procedure The test pieces shall be conditioned for at least 16 h at room temperature and then cooled to 10 C 1 C for at least 1 h. Each sample shall

33、 then immediately be wound helically around a metal mandrel having a 10 mm diameter and which is fixed in a horizontal position and pre-cooled to 10 C. The rate of winding shall be about one revolution per second. 4.5 Evaluation of the results Each test piece shall be examined for cracks, with norma

34、l or corrected vision, without magnification. Not more than two of the ten test pieces shall show cracks. If more than two samples fail, the test may be repeated one more time. NOTE A slight lifting off at the corners of the compound layer is acceptable. 5 Test report The test report shall be in acc
