GOVERNMENT MINIMUM REQUIREMENTS

The Contractor shall manufacture, package, and deliver the following PZT-4 material in accordance with the attached drawings:

QTY 21/ea.- PZT-4 Hemisphere QTY 1,254/ea. - PZT-4 Bar QTY 124/ea. - PZT-4 Bar (unpolarized) QTY 50/ea. - PZT-4 Cylinder

The parts shall be manufactured per the attached drawings:

As specified in note 7 on drawing number 8440464, electrode width and spacing shall be equidistance around the cylinders. In end use they are assembled in a stack and the stripes of all cylinders in the stack must align.

The drawings specify measurements on the PZT-4, which shall be provided in an excel spreadsheet. Measurements in pdf form alone are not acceptable. These measurements shall contain the serial number for the individual part along with (1) capacitance, (2) dissipation, (3) any additional measurements specified by the drawings, for example:

Measurement values shall conform to nominal values within tolerances specified in the drawings. As the PZT-4 cylinders are more complicated than the other items, the attached excel spreadsheet, “Example Cylinder Measurements” is an example of such measurements for the cylinder assembly. In the example, quadrant 1 is defined/chosen, and then the capacitance and dissipation of quadrants 1-4 are measured. If the cylinder measurements are performed differently than the attached example, please provide your convention.

Hemisphere drawing no. 1007, sheet 1 is for reference only, these properties do not need to be included in supplied measurements. Hemisphere measurements shall include Capacitance, dissipation, fr, fa, and coupling coefficient (k_eff), which must meet Navy type I material requirements. Hemisphere measurements shall be performed at 1 kHz.

As these materials have different lead time and manufacturing times, partial shipments are allowed not to exceed 5 total shipments, portioned between parts as follows:
