Impact Testing Machine

Listing ID #1505758

Impact Testing Machine is suitable for impact testing charpy, Izod tests with accuracy and speed. Impact Testing Machine conforms to the IS, BS & ASTM relevant standards, ensuring its efficiency.  
Following are the prominent attributes of Impact Testing Machine

• Machines are built & calibrated strictly, as per IS, BS & ASTM relevant standards
• Model YIT-216 offered as per ASTM-E 23 standard including Proof test
• Heavy impact tester can be supplied with LLOYD’s approval
• Large dial scale for clear and accurate reading free from parallax
• Simple construction of pendulum yet accurate
• Strikers & supports of high quality alloy steels
• Positive pendulum lock in IZOD, CHARPY machines to avoid accident
• Two hand operation to release pendulum-another safety measure
• Safety guards for protection for heavy impact testers
• A braking arrangement for stopping pendulum oscillations after rupture of specimen
• 'Pendulum supported on very precision antifriction bearings

 
General
The Popular pendulum impact tester model YIT – 300 is built for conducting charpy and IZOD tests on ferrous & nonferrous metals. The test methods conform to IS: 1598-1977. IS : 1757-1973, IS : 1499-1977 and BS : 131 : Part I, II & III-1972 This tester is calibrated as per IS : 3766-1977 or BS : 131 : Part IV-1972. Another pendulum impact tester model YIT-216 is built exculsive3ly for CHARPY test as per ASTM-E 23-1982 for metals. The small pendulum impact tester model YIT-15 and YIT-4 are having 15 Joules & 4 Joules impact energy conforming to IS : 867 or ASTM D-256-73 or BS : 2782 Suitable for plastic, insulating materials etc.
 
The pendulum is mounted on antifriction bearings. On release, the pendulum swings down to break the specimen & the energy absorbed in doing so is measured as the difference between the height of drop before rupture & the height-of rise after rupture of the test specimen & is read from the position of maximum pointer on the dial scale. The Charpy release mechanism is operated by two levers just near the dial, incorporating important safety measure for prevention of accidental release of the pendulum.
