CREEP TEST DEMONSTRATOR

EXPERIMENTS

TARGETS

To determine the associated with temperature and cargo on slip strain intended for four distinct materials: Polyethylene, Polypropylene, Polyvinylchloride and Lead. PROCEDURE

1 ) Mount the specimen inside test region by using the installation screws. 2 . Support the beam simply by raising the support screw (I) until it slightly elevates the light (G). 3. Close opportunities of the test out area and switch on the main power (D). 4. Change the temp to a desired value utilizing the temperature controller (A). 5. Switch on the heater (E).

6. Wait for a temperature in the test place to achieve steady-state. 7. Then simply, lower the support mess until it no longer supports the beam. almost 8. Adjust the dial evaluate (F) in order that it gives a zero reading. 9. Attach the weight hanger (H) and desired amount of dumbbells at the end of the beam. 10. Set the timer (B) to one minute, and switch on the timer (C). 10. Once a minute or so has passed (the security alarm should trigger), record the dial measure reading. 12. Repeat methods 10 and 11 for extra readings.

13. Once the research is over, shut off heater, timer and main power. 16. Tabulate the results, and plot the graph of strain vs . time. SAFETY MEASURES

1 . Often wear hand protection when seeking to retrieve a hot specimen to avoid damage. If possible, permit the specimen to cool down for at least 10 minutes prior to removing that from the oven. 2 . Will not set the temperature to exceed 80В°C, as this might cause damage to electric components and detectors in the product.
