(2) The person applying for the testing shall make available to the Certifying Authority such information about the material from which the anchor or chain cable is manufactured and its method of manufacture as that Authority may require. (Enacted 1991) Cap 369Q reg 6 Tests for anchors (1) The anchor, including its shackle if any, shall be tested by subjecting it on a verified testing machine to the proof load specified as being appropriate to its weight in Schedule 1. (2) If for the purposes of- (a) the Merchant Shipping (safety) (Cargo Ship Construction and Survey) (Ships Built Before 1 September 1984) Regulations (Cap 369 sub. leg.), (b) the Merchant Shipping (Safety) (Cargo Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations (Cap 369 sub. leg.), (c) the Merchant Shipping (Safety) (Passenger Ship Construction) (Ships Built Before 1 September 1984) Regulations (Cap 369 sub. leg.), or (d) the Merchant Shipping (Safety) (Passenger Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations (Cap 369 sub. leg.),an anchor of special type has been accepted by the Certifying Authority as being as effective as an anchor of conventional design but of greater weight, an anchor of that special type may at the request of the person presenting the anchor for testing be subjected to the test appropriate to an anchor of such greater weight : provided that the weight permitted for this purpose shall not exceed the actual weight of the anchor being tested by more than 33 1/3%. (3) The anchor, including its shackle, shall be deemed to have passed the test, if after the application of the test it is in the opinion of the Supervisor of Tests without material deformation, flaw or weakness. (Enacted 1991) Cap 369Q reg 7 Tests for chain cables (1) Before any chain cable is tested the Supervisor of Tests shall satisfy himself as to the quality of the materials from which the cable is manufactured, the method of manufacture, and its grade ascertained in accordance with Schedule 2. (2) Chain cable shall be tested by subjecting it on verified testing machines to the tensile breaking load test and tensile proof load test specified respectively in subregulations (5) and (6). (3) Chain cable of Grade 3 shall in addition to the tests prescribed in subregulation (2) be subjected to mechanical tests in accordance with subregulation (7). (4) For the purposes of this regulation 27.5 metres of chain cable shall be a length: Provided that- (a) a complete chain cable shorter than 27.5 metres shall be treated as a length; (b) where a complete cable is not exactly divisible into lengths of 27.5 metres the piece remaining shall be treated as a length, except that where such a piece remaining comprises less than two complete links it may be included in the previous length.(5) Tensile Breaking Load Tests- (i) The number of samples to be taken from lengths of the same grade and diameter presented for testing at one time shall be that set out in Schedule 3 in relation to that grade. (ii) Such tests shall be carried out in the following manner- (a) A piece of 3 links shall be selected by the Supervisor of Tests and cut from the cable, and the sample so obtained shall be subjected to the tensile breaking load specified in Schedule 4 in relation to cable of the relevant diameter. (b) If after application of such a test load the sample is unbroken and in the opinion of the Supervisor of Tests is without material flaw or other defect, such sample shall be deemed to have satisfactorily withstood the tensile breaking load. (c) If the selected sample fails to withstand satisfactorily the appropriate tensile breaking load the Supervisor of Tests shall select another sample of 3 links from the same length of chain cable, as that from which the first sample was taken, and it shall be tested in the manner specified in subparagraphs (a) and (b).(iii) If either the first or second of the 3 link samples withstands satisfactorily the tensile breaking load, each of the lengths which the test sample or samples represent shall be deemed to have passed the tensile breaking load test. (iv) (a) If both the first and second of the selected 3 link samples fail to withstand satisfactorily the tensile breaking load, the length from which the samples were taken shall be rejected and no further testing shall be undertaken upon it. (b) If required by the person on whose behalf the tests are being carried out, tests may be continued upon any remaining lengths which the test samples represented (if any); in such case each remaining length shall be subjected to tests in accordance with paragraph (ii), and if either the first or second of any 3 link samples selected withstands satisfactorily the appropriate tensile breaking load, that length shall be deemed to have passed the tensile breaking load test.(v) Where the required tensile breaking load is in excess of 650 tonnes the Director may permit in lieu of the application of the tensile breaking load test specified above such alternative method of testing the tensile breaking load of the material of the selected sample piece as is at least as effective.(6) Tensile Proof Load Test- |
