The test notches for the impact specimens for the tests have different dimensions.
It is to determine who is good looking from who is not
The cold test determines if there's change is blood pressure. The difference in Hypo and Hyperreactor is that hypo is a lot smaller.
A tensile test is performed by stretching the material until it breaks. An impact test is performed by applying a sudden shock to the material so that it fractures.
During load test the readings/performance could be monitored during load variation from zero 100% and short circuit.
Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
1) The test notches for the impact specimens for the tests have different dimensions. The Izod test is a V-notch; the Charpy test has three different specimen types: Key-hole, U-notch, and V-notch. However, other specimen types may be specified as required for both tests.2) The specimens are held differently. The Izod specimen is held in a cantilevered manner; the Charpy test is held such that the specimen rests against two supports on either side of the test notch.3) The impact location is different. The Izod test impact is against the end of the exposed cantilever; the Charpy test is struck directly behind the test notch such that the specimen undergoes three point bending.4) The test specimens have different dimensions. The basic Izod test specimen is 75 x 10 x 10mm (2.95" x 0.394" x 0.394"); the basic Charpy test specimen is 55 x 10 x 10mm (2.165" x 0.394" x 0.394")It's really a stretch to give 4 points of difference, particularly as these tests may be altered as required depending on the material performance characteristic being investigated.Source(s):Degarmo, E.

what is the difference between proffiency and diagnostic test
what is the difference between proffiency and diagnostic test
because in charpy test we uplace it in as simply supported beam
45 degree angle
The difference between a test and a demonstration is that a test is to be taken and answered and a demonstration is to be demonstrated and be told to the class
In a charpy impact test, the purpose of the notch is to provide a point of fracture at the same point for each material, to make it a fair test.
