About this file
This is a Statement of Work for machining ASTM E647 Compact Tension specimens from cast Nickel Aluminum Bronze material. Metal blanks measuring 4x3.85x1 inches will be delivered on pallets in multiple boxes and must be machined according to specifications shown on the attached technical drawing. The material contains visible porosity in some blanks, which is noted as a cautionary consideration for the machining process.
The contractor must maintain the notch orientation as indicated by the drawing outline attached to each blank and preserve the sample identification names throughout final machining. Each of the 24 samples (CT-LR1, CT-LR2, CT-LR3, CT-LR10, CT-LR11, CT-LR12, CT-CR1, CT-CR2, CT-CR6, CT-CR10, CT-CR11, CT-CR12, CT-CLR4, CT-CLR5, CT-CLR6, CT-CCR4, CT-CCR5, CT-CCR6, CT-TLR4, CT-TLR5, CT-TLR6, CT-TCR4, CT-TCR5, and CT-TCR6) must be labeled with its sample name and individually bagged after machining. Sample identification stamping or engraving is permitted only on the faces indicated by arrows on the technical drawing. Blank numbers are sequential for identification purposes only and should not be used for final labeling.

• Each metal blank has the outline of the drawing a ached to it to indicate the orienta on of the notch. This orienta on shall be maintained for final machining.
• Each metal blank reports its name on the a ached outline and wri en on it. Please refer to the list below repor ng all the blank numbers and sample names. The reported names shall be kept for the final machined samples. Stamping or engraving the name of the sample is allowed only on the faces indicated by the arrows below.
• Each sample shall be bagged separately with the name of the sample wri en on the bag.
• The material is cast Nickel Aluminum Bronze and as a cau onary note, some of the blanks have visible porosity.
• Metal blank Names are reported below. Blank numbers are not sequen al and for iden fica on only, please use the Sample Names for labeling.
