uofa:acceptanceCriteria Goal (c) intended; Goal (a) achieved: single test condition (ASTM F1717 static compression-bending at 25 mm/min, room temperature, dry). Range, repeats, and uncertainty quantification of test conditions limited. [Nagaraja Table 1, §2.4.1.2]
uofa:rationale BELOW TARGET. Authors acknowledge in §4: 'the sample size chosen for experimental testing may not meet a statistically relevant sample size' — encoded as a factor-level shortfall here. The N=11 sample size partly compensates per ASTM spinal device convention. The shortfall is documented in the decision rationale rather than blocking acceptance.
uofa:factorStandard ASME-VV40-2018
