STECH tearing strength Tester Determines the Tearing Strength of fabrics, papers, plastic films or other similar materials is determined by measurement of the work done in tearing through a fixed length of the test specimen using of Elmendorf Tear Tester. The Elmendorf Tearing Strength Tester consist a brass sector pendulum pivoted on anti-friction ball bearings on a vertical bracket fixed on a rigid metallic base. The test specimen in shape of a rectangular piece held between two clamps, one of which is mounted on the pendulum and the other is mounted on the vertical bracket. The clamps are mounted in such a manner that their holding faces are aligned with each other when the pendulum is locked in its raised position. The pendulum is released by lifting a release lever. This action causes the test specimen to tear right through. The tearing strength is indicated on a scale fitted on the pendulum against a low friction pointer pivoted on the axis of the pendulum. An adjustable knife is also mounted on the bracket on which the pendulum and the fixed clamp is mounted. It is centered between the two clamps and is used for making the initial Cut  in the test specimen. The apparatus is finished in metallic painting and bright chrome plating to give it corrosion resistant finish. Augmenting weights for increasing the range of the tester for testing high strength materials are available as optional accessories. Low strength materials can be tested by mounting multiple specimens at the same time.

Specially designed Stands are used to improve the accuracy and reproducibility of both analog and digital durometer hardness tester readings by ensuring that the presser foot is exactly parallel to the specimen table. Any analog or digital durometer can be mounted on an applicable operating stand. The operating stand is primarily intended for use on a test specimen with parallel sides. Irregularly shaped objects may be tested in a nest or a fixture to make the given surface parallel to the durometer presser foot. ASTM D 2240 specifies three categories of operating stands:  Type 1 are basic, manual operating stands. Type 2 is stands capable of controlling the rate of descent. Type 3 are hydraulically, pneumatically or electromechanical driven. Stands that fall into all three categories. For assistance in selecting the proper operating stand to fit your durometer.

STECH direct reading Specific Gravity Balance provides a simple and quick mean to read directly the specific gravity of rubber and other elastomers. Thus reducing labour and eliminating calculations. The time taken to find out specific gravity of a sample is only about half a minute. The balance consists of a rigid scale with specific gravity (SG) printed on standing vertically on a heavy base plate. To the center point at the scale, through jewel bearings to minimize the friction, a balancing arm is pivoted. At one end of the arm two stainless steel pins are hanging with yarns. One of the pin is attached with glass jar kept on the base. A guard is provided to avoid accidental falling of the jar during use. At the other and of the balancing arm a pointer is fixed which indicates the specific gravity of materials under test. A sliding weight is also provided for initial balancing of the sample of different weight a leveling of the base plate.

Durometer Hardness is used to determine the relative hardness of soft materials, usually plastic or rubber. The test measures the penetration of a specified indentor into the material under specified conditions of force and time. The hardness value is often used to identify or specify a particular hardness of elastomers or as a quality control measure on lots of material.

Abrasion Tester electrically operated with single phase motor, reduction gearbox. The machine is used to determining abrasion resistance of a cylindrical rubber specimen against abrasive cloth mounted on a cylindrical drum. The machine is made according to German Standard DIN 53516.

A measure of the indentation resistance of elastomeric or rubber materials based on the depth of penetration of a ball indentor. An initial contact force is applied to an indentor and the penetration is set to zero. The force is increased to a specified total load and the depth of penetration is measured. The IRHD value is related to the depth of indentor penetration. For highly elastic materials, IRHD and Shore A are comparable. An IRHD value of 0 represents a material with an Young's Modulus of zero and an IRHD value of 100 represents a material with an infinite Young's Modulus. The relationship between the depth of penetration (hardness) and the IRHD number is based on: FE=0.0038r0.65*D1.35

STECH ENGINEERS Ross Flexing Machine allows one end of the test specimen to be clamped firmly to a holder arm while the pierced end is placed between two rollers that must permit a free bending movement of the test specimen during the test.  During each cycle, the pierced area of the test specimen is bent freely over a 10mm ( 0.4in. ) diameter rod through a 90o angle.  The machine operates at 1.7 + 0.08 Hz (100 + 5cpm ).    Introduction   A pierced strip test specimen is bent freely over a rod to a 90o angle and the cut length is measured at frequent intervals, to determine the cut growth rate.  The cut is initiated by a special shaped piercing tool. The test gives an estimate of the ability of rubber vulcanized to resist crack growth of a pierced specimen when subjected to bend flexing.  No exact correlation between these test results and service is implied due to the varied nature of service conditions.   Procedure   Measure and record the median thickness of the test specimen taken at three points across the width at the point of the cut.  With the holder arm of the flexing machine in a horizontal position, clamp side by side the test specimens of the same making sure that the cuts are at the center point of the are of the rods.  Lower the adjustable top rollers until they just touch the test specimen and lock in this position by means of the wing nuts.  Permitting free travel of the test specimens between the rollers during the bending movement.  Start the machine and record the number of cycles by the use of a counter.  Make frequent observations, recording the number of cycles and the increase in cut length measured to the nearest 0.5mm for the purpose of determining the rate of increase in cut length.  When observing cut growth, the holder arm shall be at an angle approximately 45o from the vertical.  The test shall be continued until the cut length has increased 500%, that is, until the combined length of the cut and crack has increased to a total of 15.0mm ( 0.60in. ) or when 250kilocycles has been reached with slow cracking samples.  In some cases the cut growth is not in a straight line as a continuation of the cut made by the piercing tool, and "star – shaped " cracking may develop.  In this event, the cut growth shall be measured as the length of the longest continuous crack, regardless of its direction.  When it is necessary to stop operation of the machine temporarily, the holder arm shall be in a horizontal position, so that the test specimens remain horizontal while not being flexed.   Report   Sample identification, Specimen medium thickness, Test temperature if other than 23 + 2oC ( 73 + 3.6oF ), and The average number of cycles for each 100% increase in cut growth above the initial pierce of 2.5mm ( 0.10in. ) of the tested specimens, upto and including 500%, where possible.
