[接上页] (i) When satisfactory tensile breaking load tests in accordance with subregulation (5) have been made on samples representing any length of chain cable the Supervisor of Tests shall then test every such length separately by subjecting it to the tensile proof load specified in Schedule 4 in relation to cable of the relevant diameter and grade. (ii) The chain cable shall be deemed to have passed such test, if after the application of the test it is, in the opinion of the Supervisor of Tests, without material deformation, flaw or weakness.(7) Mechanical Tests- (i) Two mechanical tests- (a) to determine the ultimate tensile strength and related elongation, and (b) to determine the impact value, of the material from which the chain cable is manufactured, shall be carried out on one sample in the case of the test at (a) and on one sample which shall be cut into 3 specimens in the case of the test at (b), taken at places selected by the Supervisor of Tests from every 4 or less lengths of Grade 3 cable of the same diameter presented for testing at one time. The samples shall be deemed to have passed the tests if the tests show that the material continues to be within the limits of mechanical properties set out for Grade 3 cable in Schedule 2.(ii) If the sample fails in the case of test (a) or test (b) a further sample or samples as the case may be shall be selected by the Supervisor of Tests from the same 4 lengths or less as those from which the first samples were taken, and they shall be tested in the manner specified in paragraph (i). (iii) The lengths represented by the samples shall be deemed to have passed the mechanical tests if the samples referred to in (i) and (ii) have passed both the test at (a) and the test at (b).(8) For the purpose of Schedule 4 the diameter of worn chain cable tested in accordance with this regulation shall be the mean diameter where the cable is most worn. (Enacted 1991) Cap 369Q reg 8 Tests for chain cable accessories (1) Before any chain cable accessory is tested the Supervisor of Tests shall satisfy himself as to the quality of the materials from which it is manufactured, the method of manufacture, its grade ascertained in accordance with Schedule 2 and the size and grade of chain cable with which it is suitable to be used. (2) Subject to subregulation (5), every such accessory shall be tested by subjecting it on a verified testing machine to the tensile proof load test specified in subregulation (3) and samples of such accessories shall be subjected to the tensile breaking load test specified in subregulation (4). (3) Every such accessory shall be subjected to the tensile proof load test required by these regulations to be applied to the chain cable with which it is suitable to be used ascertained in accordance with subregulation (1). (4) (a) Except as provided in paragraph (b) at least one from every batch of 25 or less of each type of such accessory of the same dimensions and materials presented for testing at one time shall be subjected to the tensile breaking load test required by these regulations to be applied to the chain cable with which they are suitable to be used ascertained in accordance with subregulation (1). (b) In the case of end or joining lugless shackles the maximum number in a batch for the purposes of the test referred to in paragraph (a) shall be 50.(5) If the person presenting the accessories for testing requests that they should be subjected to a tensile proof load only and it is intended that after testing the accessories shall be used as part of a ship's equipment the accessories need not be tested in accordance with subregulations (2) and (3). In that event the strength of the accessories shall not be less than 40% greater than that of the chain cable with which they are to be used and every such accessory shall be subjected to a tensile proof load test at a load equal to the tensile breaking load test specified in the appropriate table for the cable. Where such tensile proof load test exceeds 650 tonnes regulation 7(5)(v) shall apply. (6) The accessories shall be deemed to have passed the tests if after application of the tests the accessories are in the opinion of the Supervisor of Tests without material deformation, flaw or weakness. (7) Mechanical Tests- (i) Every Grade 3 accessory and accessory incorporating a Grade 3 part which has been subjected to the tensile breaking load test in subregulation (4) shall be subjected to 2 mechanical tests- (a) to determine the ultimate tensile strength and related elongation, and (b) to determine the impact value, of the material from which the accessory or part is manufactured. Such tests shall be carried out on one sample in the case of the test at (a) and on one sample which shall be cut into 3 specimens in the case of the test at (b), taken at places selected by the Supervisor of Tests. The samples shall be deemed to have passed the tests if the tests show that the material continues to be within the limits of mechanical properties set out for Grade 3 cable in Schedule 2.(ii) If the sample fails in the case of test (a) or test (b) a further sample or samples as the case may be shall be selected by the Supervisor of Tests from the accessory or part, and they shall be tested in the manner specified in paragraph (i). |
