Subclause 2.2.2 Introduce Method 3 as follows: 2.2.2.3 Method 3 (a)General Three cable samples of 150 mm length each shall be taken from two parts of th
22、e cable, at least 1 m distant from each other. The sheath of the samples shall be cut along the direction of the cable axis and the cores and metallic screens removed. A portion of each sample sheath shall be obtained with two smooth, flat and parallel surfaces, avoiding excessive heating. The thick
23、ness of each portion should be between 1 mm and 2 mm. By means of a die or a sharp knife the test pieces with the dimensions indicated in figure 2.2.2.3 shall be obtained. -,-,- HD 605 S1:1994/A2:2001- 4 - A central longitudinal cut, perpendicular to the width of the test piece, shall be made with a
24、 sharp razor to a point of 4 mm from the wider end. (b)Procedure Test each test piece in the following way. Place the halves of the split end in the jaws of a tensile testing machine and separate the jaws at a rate of (500 5) mm/min. The maximum load needed for the complete tearing of each test piec
25、e shall be recorded. (c)Evaluation of results The tear resistance is determined by dividing the maximum load (in N) by the thickness of the test piece (in mm). The mean value of the results obtained shall be in accordance with the requirements in the particular specification. Subclause 2.2.8.6 Repla
26、ce the third paragraph with the following: Make two parallel cuts separated by (13 1) mm in the semi-conducting insulation screen material, down to the insulation and longitudinally from end to end of the core sample. Remove approximately 50 mm length of the 13 mm strip from each end of the core by
27、manually pulling it away from the core. Mount the sample in a tensile test machine, with one end of the strip clamped in the upper jaws, and with the sample held horizontally at approximately 90 to the clamped strip. Measure the force to separate the 13 mm strip whilst maintaining the strip at appro
28、ximately 90 to the sample, using a pulling speed of approximately 8 mm/s. Continue until approximately the midpoint of the sample. Repeat the test from the other end of the sample.

29、the second paragraph with the following: The cross-sectional area may be determined by weighing a test piece of approximately 350 mm from the aluminium strip material. The test piece length shall be measured with a tolerance of 0,5 mm, the mass shall be measured with a tolerance of 0,02 g. The densi
30、ty of aluminium shall be taken as 2700 kg/m3. Subclause 2.4.1.7 Replace the first sentence of the first paragraph with the following: Bend the cable sample around a test cylinder at ambient temperature for at least once complete turn. Subclause 2.4.1.8 Replace with the following: 2.4.1.8 Cold bend t
31、est A sample of the cable with a length of at least five times the test drum diameter shall be subject to the partial discharge test in accordance with 3.10.3. The sample shall then be cooled to 0C for at least 4 h. The sample shall then, without delay, be bent around a test cylinder, for at least o
32、ne complete turn. It shall then be unwound and the process repeated after rotating the sample through 180 about its axis. The sample shall be bent at a reasonably uniform speed, each half cycle of the test taking approximately 1,0 s per millimetre of overall cable diameter. The diameter of the test
33、cylinder shall be not greater than 20(D + d) mm, where D is the overall diameter of the cable and d is the conductor diameter as detailed in the cable specification. The sample shall then again be subjected to the partial discharge test in accordance with 3.10.3. The insulation, lead alloy sheath an
34、d oversheath shall then be visually examined. Subclause 2.4.3 Replace the first paragraph with the following: The test shall be carried out on a sample of sheath taken from a complete cable. -,-,- HD 605 S1:1994/A2:2001- 6 - Subclause 2.4.12.3 Delete the title and text and insert “Spare”. Subclause
35、2.4.18 Delete the title and text and insert “Spare”. Subclause 2.4.22 Introduce new subclause as follows: 2.4.22 Abrasion test (conic piece) A complete piece of cable shall be tightly tied to a fixed metallic base. A metallic conic piece shall be applied to the superior generatrix of the cable. The
36、conic piece shall have a radius of curvature at its point of 1 mm and the angle shall be of 90. The mass of the conic piece shall be as given in the particular specification. The conic surface shall not be rough. The conic piece shall be subjected to a to-and-fro motion, at constant speed, between t
37、he A and B marks, (see figure 2.4.22). Figure 2.4.22 The characteristics of the test shall be: Distance between A and B: 50 cm 10 cm Speed of the conic piece between A and B: 0,3 m/s with a tolerance of 5%. At the end of the specified number of motions it shall not be possible to see, with normal or
38、 corrected vision without amplification, the metallic screen under the sheath between the A, B marks. -,-,- - 7 -HD 605 S1:1994/A2:2001 Subclause 2.4.23 Introduce new subclause as follows: 2.4.23 Resistance to UV rays (a)Test principle and definition of the light source This test is based on the pro
39、longed exposure of the flat surface of the outer side of the cable test specimens to ultra-violet rays. The light source used should be such that in a dry atmosphere (relative humidity below 30%) the exposed surface of the two flat surfaces of the test specimen, the side corresponding to the outside
40、 of the test specimen cable, receives a radiation in which the wavelength-dependent energy distribution complies with the values indicated on the curve (figure 2.4.23). Figure 2.4.23 To take account of the dispersion of the lamps and their ageing, the following tolerances are accepted: (i)20% in the
41、 area of ultra-violet radiation (wavelengths below 400 nm). (ii)50% for the visible radiation (wavelengths above 400 nm) This radiation may be obtained with a xenon lamp fitted with quartz filters. (b)Test method The samples shall follow a cycle of 5 days. During these days they shall be subjected t
42、o the following tests: Exposure for one day to light radiation in a humid atmosphere, (relative humidity 85%), at the temperature of (25 2)C with sprinkling. NOTE The sprinkling of demineralized water lasts three minutes per period of twenty minutes; it is done with the aid of injectors in which the
43、 water discharge should be sufficient to ensure the washing of all the test specimens. HD 605 S1:1994/A2:2001- 8 - Exposure for one day in a humid atmosphere at the temperature of (50 2)C with thermal shocks obtained by being put into an enclosure kept at (-25 2)C for three one-hour periods. The hot
44、-cold or cold-hot transfers should be done in the shortest time possible. The time the test specimens remain in a humid atmosphere between two thermal shocks should be one hour or more. Two days exposure to light radiation in a dry atmosphere during which the temperature is kept at (70 2)C and the r
45、elative humidity is less than 30%. The fifth day, exposure for 8 hours with 0,067% in volume of sulphur dioxide and kept at a temperature of (40 3)C with saturating humidity. For the last 16 hours the door of the enclosure is left open to the laboratory environment. During the exposures the test-pie
46、ces, similar to those defined for the tensile test, shall be placed on supports, taking care that they are not subjected to any tensile force. At the end of the test, the samples shall be removed and kept protected form direct sunlight in the laboratory atmosphere for 24 hours at least. A visual ver
47、ification shall then be carried out to ensure that there is no significant discolouration between the aged test pieces and those not subjected to the test. (c)Test pieces The test requires two batches of six test-pieces; one of them being the reference batch. The reference batch shall be kept at amb
48、ient temperature avoiding direct sunlight throughout the environmental testing. The other batch shall be subjected to the specified 5 days cycle and then conditioned like the reference batch for 24 hours. After the visual for any significant discolouration the elongation at break (A) and tensile strength (R) of the test-pieces from each of the batches shall be measured in accordance with EN 60811-1-1 subclause 9.2, i.e. respectively: Reference batch:A0 and R0 Exposed batch:A1 and
