Canvas shoes are extensively used in games and sports, physical training and other general purposes. These are also known as PT shoes. This standard was originally published in 1966 and subsequently revised during 1984. Considering the technological developments and in the light of experience gained, the Committee decided to revise the standard. In this revision, the following new requirements have been included in this standard: a) Adhesion test, b) Consolidation test, and c) Mass. Requirements of tensile strength, elongation at break and compression set of soles have also been included to ensure better performance of rubber soles and heels. In order to ensure robustness of soles and heels on prolonged storing even under rigorous conditions, the requirement for ageing at 70 ±. 1°C for 168 h has been introduced in this standard. In view of the fact that a lot of new raw materials and grinderies for shoes have been developed and are extensively used in the industry, the Committee decided to give more stress on the performance requirements of shoes rather than prescribing requirements for each and every Component and grindery. The composition of the Committee responsible for formulation of this standard is given in Annex C. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

The supporting frame shall be of such design that clamps for strip specimens hang on it vertically and mandrels for rings specimens are supported on it horizontally. The frame shall have sufficient height to permit the weight carrier to be suspended from the test specimens by means of clamps and shall hang freely during the progress of the test, provision shall also be made to support the mandrels so that they revolve freely with minimum friction. Suitable apparatus is shown in Fig. 2. C-1.2 Calibration of Apparatus Calibrate the weights annually. C-1.3 Cutting Tool Maintain the cutting tool carefully so that the edge is sharp enough to avoid leaving ragged edges and pulling outside threads from the fabric. C-2 Procedure C-2.1 Strip Test Piece (see Fig. 2) Separate the parts of the strip to be tested by hand at one end of the strip specimen and at a sufficient distance to permit the jaws of the testing clamp to be attached. Suspend the strip on the spike of the vertical frame or board and attach the ply to be separated, to the grip. Attach the loaded scale pan to the grip through a light spring. The total mass of the grip, spring, loaded scale pan and attachments shall be taken as the applied load. Obtain either the load required to cause separation of 25 mm/min graphically by selecting various loads or for a known or specified load, determine the rate of separation. Repeat the procedure on the separate plies from the face ply to the centre ply. Test the second specimen conunendng with the back ply and proceeding again to the centre ply. NOTE — Precautions Shall be taken during the test to preveat side threads from pulling out and interfering with the test result. Where this occurs excessively due to the threads not being parallel to the edge of the strip, the test piece shall be discarded and a fresh one prepared. 2
