Material testing standards are established to ensure that the results obtained from the tests are repeatable and can be relied upon in the selection and acceptance of a material for use. The testing standards achieve this by: Select one: 1. Specifying methods for sampling and preparation of the specimens used in the test. 2. Specifying the type of equipment to be used in the test and how to ensure that the equipment is functioning properly. 3. Describing precisely the testing conditions and procedure. Incorrect 4. All of the above.

Why are the Charpy or Izod impact tests conducted on specimens of a given material over a range of temperatures?
Select one:
1. To compensate for the expansion of the testing rig.
Incorrect
O 2. To establish the temperature range at which ductile-brittle transition occurs.
O 3. To correlate test results with published data
4. To compensate for temperature variation in the laboratory.
Incorrect
Why are the specimens used in the Charpy or Izod impact tests provided with a precisely shaped and positioned notch?
Select one:
1. To secure the specimen in the testing rig.
Incorrect
2. To finely adjust the weight of the specimen.
O 3. To prevent damage to the impacting pendulum hammer.
O 4. To ensure the deformation in the specimens will occur at the notched surface.
