RETESTS Should any of the tests not comply with the requirements of this Specifications, the following additional tests shall be carried out in the same manner as required to be made in the first instance. 15.1 Chemical analysis - If the results of chemical analysis do not conform to the composition requirement as in 6.1 above, two new samples shall be taken on different pieces from the same cast. If the test results on these two samples satisfy the requirements, the lot represented shall be accepted, if either of the sample fails, material shall be rejected.

15.2 Mechanical Properties -If any of the test pieces first selected fails to pass any of the

tests specified in this specification, two further samples shall be selected for testing in respect of

each failure. If the test pieces from both these additional samples pass, the material

represented by the test samples shall be deemed to comply with the requirements of that

particular test, if either of the test pieces from the additional sample fails, the material

represented shall be considered as not having complied with this standard.

15.3 Tensile Tests – Two additional tensile tests may be made from other fishplates taken from the same lot from which the test piece was taken for the tensile test which failed, and should any of these not comply with the provisions of Clause 7.1, all the fishplates of the lot shall be rejected. 15.4 Bend Tests – Two additional bend tests may be made with other fishplates taken from the same lot from which the test piece was taken for the bend test which failed, and should any of these not comply with the provisions of Clause 12.1, all the fishplates of the lot shall be rejected.

16. MANUFACTURE (For Fish Plate Combination) The top and bottom fishing angles of these fishplates will be left in the as drop-forged or machined condition subject to compliance with Clause 18 of this Specification. If the fishplates are, however, manufactured by hand forging, under special permission of the Purchaser or the Inspecting Officer, the bearing surfaces shall be machined. The four corners of the fishplates will be rounded off after cutting to a radius of 12mm. Holes are not to be punched but must be drilled. The holes shall be clean without burrs on either side, accurate in pitch and in the positions as specified. The bolt holes in the fish plates shall be champhered before offering fish plates for inspection.

shall prepare two sets of profile and nipple gauges as per standard RDSO drawing for fish

plates, made up of stainless steel for each section of fishplates ordered for testing the accuracy

of the fishing planes and the bolt holes. Nipple gauges shall be accurately planed to represent

the fishing of the rail with which the fishplates are to be used and fitted with suitable studs for

testing the accuracy of the bolt holes. All gauges along with their drawings shall be approved by

the QA (Civil) Directorate of RDSO prior to use. Every fishplate shall be checked with respective

gauges and any fishplate which fails shall be rejected.

20. SAWING TO LENGTH All fishplates shall be sawn within 1.5mm above and below. The specified length and the ends shall be square. All burrs caused by the saw shall be removed. 21. HOLES IN FISHPLATES 21.1 The bolt holes in the fishplates other than fish plate combination shall be either drilled or hot punched as specified by the Purchaser. If the holes are to be drilled, the fishplates shall be made perfectly straight along the lines of fishing, for the full length of the plate before drilling is commenced. If the holes are to be punched, the punching of all holes shall be done at one stroke of the machine before the fishplates have cooled to below a red heat from the rolling temperature and the fishplates shall then, whilst still hot, be straightened by gradual pressure between blocks of full length of the fishplate. 21.2 In case of fish plate combination holes shall be drilled and not punched as mentioned in Clause 16 above. 21.3 The bolt holes in the fish plates shall be chamfered to the satisfaction of Inspecting official.
