CFS Industry Standards & Regulations 3 — Questions and Answers
Question 1: The Fastener Quality Act (FQA) of 1990 primarily addresses which concern in the US fastener industry?
- Price fixing among manufacturers
- Counterfeit and misrepresented fasteners in commerce (Correct answer)
- Import tariffs on foreign fasteners
- Environmental disposal of fastener waste
Correct answer: Counterfeit and misrepresented fasteners in commerce
The FQA was enacted to address the proliferation of counterfeit and misrepresented fasteners entering US commerce, particularly in safety-critical applications.
Question 2: Under ASME B18.18, what is the 'lot' defined as for acceptance sampling purposes?
- All fasteners produced in a calendar year
- All fasteners of the same type from the same heat treatment batch
- A collection of parts of the same kind submitted for inspection at one time (Correct answer)
- Any shipment exceeding 10,000 pieces
Correct answer: A collection of parts of the same kind submitted for inspection at one time
ASME B18.18 defines a lot as a collection of parts of the same type, class, size, and specification submitted for inspection at one time from a single source.
Question 3: Which standard governs the qualification and approval of aerospace fastener manufacturers under the National Aerospace and Defense Contractors Accreditation Program?
- AS9100
- NADCAP AC7102 (Correct answer)
- MIL-STD-1312
- AMS 2750
Correct answer: NADCAP AC7102
NADCAP AC7102 is the audit criteria used to accredit fastener manufacturers supplying the aerospace and defense industry through the NADCAP program.
Question 4: What distinguishes a 'Grade 5' bolt from a 'Grade 8' bolt under SAE J429?
- Grade 5 is metric, Grade 8 is inch series
- Grade 8 has higher minimum tensile and proof load strengths (Correct answer)
- Grade 5 requires zinc plating, Grade 8 does not
- Grade 8 is for outdoor use only
Correct answer: Grade 8 has higher minimum tensile and proof load strengths
SAE J429 Grade 8 bolts have higher minimum tensile strength (150 ksi) and proof load than Grade 5 bolts (120 ksi tensile), making them suitable for higher-stress applications.
Question 5: ISO 3269 specifies procedures for which fastener quality activity?
- Chemical composition testing
- Acceptance inspection and sampling (Correct answer)
- Torque-tension testing
- Hydrogen embrittlement evaluation
Correct answer: Acceptance inspection and sampling
ISO 3269 specifies the acceptance inspection procedures and sampling plans used for fasteners, defining AQL levels and sample sizes.
Question 6: Which federal agency oversees enforcement of the Fastener Quality Act in the United States?
- OSHA
- EPA
- NIST
- The Department of Commerce (Correct answer)
Correct answer: The Department of Commerce
The National Institute of Standards and Technology (NIST) under the Department of Commerce administers and enforces the Fastener Quality Act.
Question 7: What is the significance of the 'F' prefix in ASTM fastener standards such as ASTM F593?
- It denotes ferrous materials only
- It indicates the standard is developed by ASTM Committee F16 on Fasteners (Correct answer)
- It means the fastener has fire-resistance certification
- It designates foreign (non-US) thread forms
Correct answer: It indicates the standard is developed by ASTM Committee F16 on Fasteners
The 'F' prefix in ASTM fastener standards indicates the standard was developed by ASTM Committee F16, which is responsible for fastener standards.
