Form / Attachment / Pricing Sheet

This document provides detailed specifications and instructions for the machining of ASTM E647 Compact Tension Specimens. It outlines the material, dimensions, and labeling requirements for the metal blanks that will be used.

• Material: Cast Nickel Aluminum Bronze. Note that some blanks may have visible porosity.
• Dimensions: Blanks are 4x3.85x1 inches.
• Notch Orientation: Each blank has a drawing indicating notch orientation, which must be maintained for final machining.
• Labeling: Each blank is identified by a "Sample Name" which must be used for the final machined samples. Stamping or engraving is permitted only on specified faces. A list of "Blank Numbers" and corresponding "Sample Names" is provided for identification.
• Packaging: Each machined sample shall be bagged separately with its name written on the bag.

This attachment is crucial for any vendor tasked with machining these specimens. It specifies the exact material, dimensions, and critical orientation requirements. Adherence to the provided "Sample Names" for labeling and packaging is mandatory. Bidders must carefully review the provided diagram and list of sample names to ensure accurate machining and identification of the specimens.

Form / Attachment / Pricing Sheet

This document is a technical drawing (DWG. NO. CT-NAB) for a "CT Sample Cast NAB" specimen. It provides detailed specifications for manufacturing this sample, likely for material testing or quality assurance purposes.

• Dimensions: Specifies overall dimensions (e.g., 3.75 x 3.60 x 0.750 inches) and critical features like notch dimensions (0.12 max depth, 50° max angle), hole sizes (2X Ø.750, 2X Ø.825, #8-32 tapped holes), and surface finish requirements (32 or better).
• Tolerances: Details acceptable deviations for dimensions (e.g., ±0.004 TIR for perpendicularity/parallelism, ±0.01 for notch tip intersection, ±0.005 for hole diameters) and angles (±5°).
• Notch Preparation: Refers to ASTM E647, paragraph 7.3 for specific notch preparation.
• Material: Not specified in the drawing itself, but the title suggests "Cast NAB".
• Inspection: Drawing is to be interpreted per ASME Y14.5-2009.

This drawing is crucial for any bidder involved in the manufacturing, machining, or quality control of the "CT Sample Cast NAB" specimen. It defines the precise physical requirements and tolerances that must be met. Bidders will need to ensure their processes and capabilities align with these specifications to produce compliant parts.
