Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals, or non metals such as foam, rubber, leather, textiles, plastic, paper or finished products such as rods, ropes, yarns, belts etc. This two properties often play amajor role in determining the suitability of any raw materials for specified application. It is therefore, of utmost importance to determine these characteristics accurately, |

conveniently and quickly. The “HIROSHIMA” TENSILE TESTING MACHINE provides a relatively inexpensive way for determining the Tensile Strength and elongation of Cotton, Jute, Silk Yarn in single strand. They are based on constant rate of traverse principle, in which one end of the test specimen is held in a stationery grip while the other end is moved at a known fixed speed with the help of a motor, gear box and screw arrangement.
The load exerted on the stationary grip is measured by a load cell and a digital indicator. The digital indicator has a peak hold facility to indicate breaking load, tare facility for using various grips. The elongation of the test specimen is measured on a linear scale fixed on the frame of the tester which indicates the distance between the grips. Changing the belt on a set of V belt pulleys can change the speed of traverse of the lower grip..
The frame of the test is fabricated from heavy mild steel section to give it the required rigidity and strength. Various built in safety arrangements such as over and over travel protection, and automatically stopping of the motor on failure of the test specimen are provided.
The tester is finished in dark enameled painting and bright chrome / zinc plating to give it a corrosion resistant finish. The tester is supplied complete with electrical, which includes micro-switches, push buttons and contactors for safe and convenient operation. |
