Model XJ-50Z complete impact testing machine conformed to the following norms: International: ISO179 plastic CHAPRY and ISO180 plastic IZOD impact test method, National: GB/T1043 CHARPY and GB/T1843 Hardened plastic IZOD impact test method machine industrial standard: JB/T8761 Plastic impact testing machine.
3. Transportation and installation: 1) Unloading / Transporting the package, please avoid sloping its package, impact and strong vibration is prohibited. 2) Before installing the testing machine, please clean the anti rust oil on the machine, meanwhile; please use soft cloth to wipe the surface of machine to clean dusts, and please do not try to remove the accessory during this procedure. 3) Working condition should chose one that without vibration and keep it away from causticity medium. 4) Testing machine should be mounted on the steady base, and its weight is suggested become 40 times than the pendulum that in use. Level standard 0.2/1000, and preserve foundation bolt on the base.
4. Structure and working principle The structure of this machine please refer to diagram A and diagram B. 1)Please chose proper pendulum energy according to the impact sample, It is suggested to chose a pendulum with useful available energy within 10-80% range, so that the impact energy is included in this range. To install the pendulum: please release the fasten screw (A-7), keep the positioning bolt on the impact pendulum (A-4) inside the positioning hole on the axes (A-10), Connect the up-cover (A-8) and fasten the screw. 2) The Charpy testing machine can be changed with its supporting span to suitable for different specimen. Use inner hex spanner release the bolt, moving the anvil left or right; Clamp the centering plate on the impact edge and make the anvil touch the centering plate scale. Remove the centering plate after adjustment. 3) Put on specimen, release the fasten screw on the movable plate, turn the wheel to adjust the distance between impact edge and specimen so that the two spaced with 0.5mm. after this procedure, fasten the screw. On condition that using notched specimen, adjust the centering place of specimen through one caliper. 4)After setting specimen, lifting the pendulum (A-4) until it is hanged on the position lock (A-10), Then press the impact button on panel (A-5) and the pendulum will be released automatically. Machine record peak absorbed energy. 5) Refer to ISO standard for test results processing.
