4. AQL is the __________
a) Acceptable Quality Level
b) Acceptance Quality Level
c) Associated Quality Level
d) Assigned Quality level
Explanation: The main focal point of MIL STD 105E is AQL. The AQL stands for Acceptable Quality Level. This is the lowest quality of a product to be accepted.
5. Which of these is a derivative civilian standard which is quite similar to MIL STD 105E?
a) ANSI/ASQC Z1.4
b) ANSI/ASQC Z1.1
c) ANSI/ASQC Z1.8
d) ANSI/ASQC Z1.7
Explanation: There is a derivative civilian standard originated from MIL STD 105E, ANSI/ASQC Z1.4. It is quite similar to the MIL STD 105E standard.
6. Which of these ISO standards were adopted from MIL STD 105E?
a) ISO 14000
b) ISO 9000
c) ISO 2859
d) ISO 6000
Explanation: MIL STD 105E was also adopted by the international organization for standards as ISO 2859. This is quite similar to ANSI/ASQC Z1.4.
7. How many sample inspection levels are used in MIL STD 105E?
Explanation: The sample size used in MIL STD 105E is determined by lot size and by the choice of inspection levels. Three general levels are provided.
8. Level I of inspection of MIL STD 105E requires about __________ amount inspection as Level II.
Explanation: There are generally 3 levels of inspection in the case of MIL STD 105E. The level I requires about one-half the amount of inspection as Level II.
9. Tightened inspection is instituted when at least ______ out of 5 consecutive lots have been rejected on original submission.
Explanation: When the normal inspection is in effect, tightened inspection is instituted when at least two of five consecutive lots have been rejected on original submission.
10. When is the normal inspection to be instituted instead of tightened inspection?
a) When 3 lots are rejected consecutively
b) When 2 lots are accepted consecutively
c) When 5 lots are rejected consecutively
d) When 5 lots are accepted consecutively
Explanation: When tightened inspection is in effect, normal inspection is instituted when five consecutive lots or batches are accepted on original inspection.
11. When should the inspection with the provision of MIL STD 105E be terminated?
a) When at least 10 consecutive lots remain on tightened inspection
b) When at least 7 consecutive lots remain on normal inspection
c) When at least 5 consecutive lots remain on tightened inspection
