About this file
This is an engineering drawing specification for a CT Sample Cast NAB component. The drawing provides detailed dimensional requirements and manufacturing specifications for what appears to be a cast test specimen used in materials testing applications.
The component measures 3.75 inches in length and 3.60 inches in height, with a width of 2X 3.000 inches. Key features include two circular holes with a diameter of 2X .750 inches (tolerance +.005/-.000), two #8-32 tapped holes spaced .20 inches apart, and a machined notch with a 50-degree maximum angle. The notch preparation must comply with ASTM E647 paragraph 7.3. All surfaces must be perpendicular and parallel within ±0.004 TIR, and surface finish including holes must be 32 Ra or better. The notch intersection tips must be equally distant from the specimen's top and bottom within 0.01 inches. Tolerances follow ASME Y14.5-2009 standards, with fractional tolerances of 1/32 inch, two-place decimals of ±0.02 inch, and three-place decimals of ±0.002 inch. The drawing is property of NRL and prohibits reproduction without written permission. The scale is 1:2, and the document is sheet 1 of 1 with drawing number CT-NAB.
