The AS9102 first article inspection procedure (FAI) is compliant with SAE standard Rev B dated 10-16-2014.
Prime contractors in the aviation, space and defense industries flowdown the requirements of the AS9102 first article inspection procedure to Suppliers that have design authority for critical components and assemblies.
Consider purchasing the SAE sponsored AS9102C standard dated 6-28-2023.

atk.com asked about significant digits for reports according to the AS9102 first article inspection procedure ( FAIR ).
“Can you help us report significant digits related to first article inspections?”
See ASTM E 29 Standard Practice for using significant digits in test data to determine conformance with specifications, which is applicable to all scientific work regardless of its nature (including the process for the first article inspection procedure).
“When the digit next beyond the last place to be retained is less than 5, retain unchanged the digit in the last place retained.
When the digit next beyond the last place to be retained is greater than 5, increase by 1 the digit in the last place retained.
When the digit next beyond the last place to be retained is 5 and there are no digits beyond this 5 or only zeros, increase by 1 the digit in the last place retained if it is odd, leave the digit unchanged if it is even. Increase by 1 the digit in the last place retained if there are digits beyond this 5.
The rounded value must be obtained in one step by direct rounding of the most precise value available and not in two or more successive roundings.”
We cite ASTM E 29 in work instructions when it directs the User to report significant digits for compliance to a specification limit with 1, 2, 3, 4 or more decimal places. If your measuring device’s readout displays more decimal places than the specification requires, ASTM instructs you to round your reading to match the number of decimal places in the specification – that’s where ASTM E 29 comes in handy…
0.0211″ to 0.0214″ must be rounded down to 0.021″ for 2 significant digit specifications;
0.0215″ to 0.0219″ must be rounded up to 0.022″ for 2 significant digit specifications;
(unless the last retained digit from the rounding method is even, e.g., 0.0225″ is rounded down to 0.022″ since the last digit retained is even, while 0.0226″ is rounded up to 0.023″)
0.0211″ to 0.0219″ must be applied as observed – no rounding is possible if the measurement equipment can only read to the 4th decimal place. If the equipment is capable of reading beyond the 4th decimal place then round to the last digit retained as described herein paying particular attention to whether the retained digit is odd or even when followed by the numeral 5.
499.1 to 499.4 must be rounded down to 499
499.5 to 499.9 must be rounded up to 500
600.1 to 600.5 must be rounded down to 600
600.6 to 600.9 must be rounded up to 601
Hope this information helps your project.
