STEEL TOE IMPACT TESTER

The toe portion of shoes used for industrial applications or used in mines shall be sufficiently rigid so as not to get pressed down beyond a specified limit when a heavy block falls down on it, thus preventing crushing of or injury to the toe of the user. The toes of miner's safety boots or industrial shoes are generally reinforced with steel toe­ cap to provide rigidity to them. Whether these toe-caps are sufficient robust so as to fulfill their desired function is ascertained by subjecting the toe-cap assembled in a cut-out shoe to an impact by a falling weight in suitable equipment. The toe-cap shall not press down beyond a specified limit during the impact.

Technical Data

ROSS FLEX TESTER WITH COOLING CHAMBER

The ability of any shoe sole to with stand repeated bending experienced during walking without developing a crack within the estimated life span of the shoe is a very important factor for determining its quality. Also, its ability to withstand propagation of any slit formed due to a sharp edge or pointed object piercing it during walking is equally important in assessing its quality. These abilities of any sole can be evaluated with the help of a Ross Flex Tester.

    COMPRESSION RESISTANCE TESTER CUM NAIL PENETRATION TESTER

    Safety / Protective footwear should give safety to the toe of the user under compression load and to the sole against nail penetration. Compression resistance is determined by subjecting the footwear to a specified compression load and measuring the clearance with the help of a modeling clay cylinder. Nail penetration resistance is measured by measuring the maximum force required for a nail to penetrate through the sole.

    Technical Data

    Capacity of the load cell : 20, 000 N X 10 N

    Speed of movement of platen : 5 mm/minute (for compression test) 10 mm/ minute (for penetration test)

    DIN ABRESSION TESTER

    One of the methods for determining the abrasion resistance of elastomers is by a Rotating Drum Abrasion Tester. In this test the elastomeric under test is abraded against an abrading surface mounted over a rotating drum. The abrading surface has a specified abrading power. The test specimen, which is in form of a button, is held against it under a fixed load. The abrading surface is made to rub against the test specimen by rotating the drum at a fixed speed, the test specimen being meanwhile made to move along the axis of the drum.

    Technical specification

    Diameter of test specimen : 16 + 0.2 mm

    Height of test specimen : 6 to 10 mm

    Diameter of rotating drum : 150 mm

    Length of rotating drum : 470 mm

    Speed of rotation of cylinder : 40 + 2 RPM

    Lateral movement of test specimen holder : 4.2 mm per revolution of drum

    Load on test specimen : 10 N / 5 N

    Inclination of axis of specimen holder : 3° from vertical

    Total length of abrading run : 40 m (about 84 rotations )

    Abrasive cloth : 450 mm wide X 473 mm long coated with aluminum oxide abrasive grain of 60 grit

    Motor : ¼ HP – 230 volts AC

    FLEXO METER

    The Ability of light leathers and leather –cloth used in manufacture of shoe uppers. Gloves, and garments to withstand repeated flexing without cracking is determined with the help of a flexing endurance test in this test specimens in shape of rectangular pieces are folded and clamped at each end to maintain them in a folded position in a set of grip s, one of which is fixed while the other is able to oscillate. The movement of the oscillating grip causes the fold in the test specimen to run along its center. This operation is carried out repeatedly and the test specimens inspected periodically to assess the damage produced. The equipment used for this is called as Flex-o-meter.

    Technical Data

    Angle of oscillation of grips : 22.5+0.5

    Flexing frequency : 100+5cycles/minute

    Dimensions of test specimens : 70x45 mm

    Maximum number of test Specimens that can be tested At on time : SIX

    WATER RESISTANCE TESTER - (PENETROMETER)

    The uppers of shoes get folded over the toe portion every time a step is taken. These repeated folding cause the finished grains to start cracking, resulting in loss of water resistance. To ensure that the leather uppers retain their water resistance for a reasonable period of use, the action of such folding on them is simulated by subjecting test specimens taken from the leather to a water penetration test using a electrometer.

    In this test the test specimens are held in form of thoughts between two cylindrical grips one of the grips is then repeatedly moved towards and away from the other along their common axis .the test specimens are kept immersed in a water bath unto a part of their periphery. Penetration is detected when electric conductivity is established between the inside and outside surfaces of the test specimens

    The time needed to cause penetration of water through the test specimens is determined and taken as an index of water resistance of the leather. The test can be continued to determine the percent gain of weight of the specimen due to water absorption and also to determine the mass of water that has transmitted over a known time interval.

    Technical Data

    Dimensions of test specimens : 60mm X 70mm

    Number of test specimens tested at a time : Three or four

    Diameter of cylindrical grips : 30 mm

    Flexing frequency : 50 cycles per minute

    Travel of moving grip : 2.0, 3.0, 4.0 or 6.0mm (5, 7, 5, 10, or 15%)

    Motor : ¼ HP single phase 230 V AC

    WATER VAPOUR PERMEABILITY AND WATER VAPOR COEFFICIENT

    Water vapour permeability of leather is evaluated by clamping a circular test specimen over the mouth of a bottle containing a solid desiccant and subjecting it to a rapid current of air. The air inside the bottle is circulated by keeping the desiccant in motion. The increase in weight of the bottle over a specified interval of time gives the quantitative measure of the water vapor permeability of the leather sample under test.

    Speed of rotation of wheel : 75 rpm

    Distance between axis of rotation and axes of bottles : 67 mm

    Maximum number of bottles which can be mounted at a time : Six
