| Units and quantities in Quality |  |
| Units Units must have the same physical quantity, for example " Length ": Characteristic Unit Test Unit Least Measurable Unit (of the instrument used to test the characteristic) Example The quality of item "Tube" is determined by checking the following characteristics: Length Diameter Volume
Characteristic | Length
Characteristic Unit | m (meter)
#TB@qmptc005 | -
Test Unit | cm (centimeter)
Quantities Order Quantity The quantity for which the inspection is required. Consequently, the result of the inspection order decides the quality of this quantity. Depending on the origin of the order, the applicable quantity is: Sales order quantity Purchase order quantity (the delivered quantity) Production order quantity Production batch quantity Sample Size The sample size is the total quantity of samples that are to be tested of the order quantity, expressed in the unit of the sample size. The sample size can be entered as a figure or as a percentage of either the order quantity or the frequency. Sample Quantity The actual quantity which is drawn from the total quantity. Each sample quantity can be split up into smaller parts or test quantities. Test Quantity The test quantity is a part, an exact factor of the sample size, which is tested each time, and is expressed in the same unit as the sample size. For each test quantity, the result of the test can be entered in session Sample Test Data (qmptc1115m000). Example
Inspection Order Quantity | 1000 pieces
Test Type | Single Sampling
Sample Size [%%] | 50%
Sample Size | 500 pieces (1000 * 50% = 500)
For this sample size, three samples are drawn:
Sample | Test Quantity | Sample Quantity
1 | 50 pieces | 200 pieces
2 | 50 pieces | 200 pieces
3 | 50 pieces | 100 pieces
- | Total | 500 pieces
