Practical #1: QUANTIFYING QUALITY.

1: Explain any four of the tests that might be applicable to a quality characteristic. Tensile test on a metal. Impact test. Coating thickness test.
Hardness test on a metal. Diameter using laser mic. Hardness test on rubber.
Measurements using the arm. Ultrasonic Tester. Eddy Current tester.

Practical #2: Scales Calibration.

1. What is the maximum permissible deviation of a 500g F2 grade weight?

2. List the seven classes of mass standards.

3. What is hysteresis and when might it be important in mass measurement?

4. What is air buoyancy and when might it be important in mass measurement?

Practical # 3. Gauge Capability Study [R&R]

1. What is the difference between an R&R study and Measurement System Analysis?

2. What are the strengths of R&R studies?

3. Explain the significance of the following statement.“A high EV value relative to AV indicates the need for a better gauge. A high AV value relative to EV indicates the need for better training”.

Practical #4: Title: Micrometer Calibration.

1. How is the SI base unit for length defined?

2. Explain the use of a laser scan micrometer?

3. Explain why hysteresis either is or is not relevant to micrometers.

4. Why is it important to calibrate an instrument in its “as found” condition?

Practical #5: CAPABILITIES.

1. Briefly explain why the TUR approach to measurement process selection is superior to the TAR one.

Practical #6: Title: Measurement efficiency.

1. What did Price say about the inspection?
“No inspection without.

2. List three disadvantages/dangers associated with manual recording and analysis of measurement data.
