STATEMENT OF WORK

FOR

QUALITY EVALUATION TESTING OF

TOMAHAWK SHROUD EXPLOSIVE BOLT (P/N 2220628)

1.0 INTRODUCTION

1.1 Scope. This statement of work (SOW) defines the efforts to conduct non-destructive and functional testing of twelve (12) Shroud Explosive Bolts (Raytheon P/N 2220628) at the new test location Pacific Scientific EMC in Chandler, AZ. The explosive bolt test sample will be furnished by the Naval Surface Warfare Center, Indian Head Division (NSWC IHD).

1.2 Background. This will be the third Service Life Assessment Program (SLAP) for the Shroud Explosive Bolts. Past SLAP testing was conducted at Pacific Scientific EMC in Hollister, CA facility under contract N00174-14-D-0014 / D.O. N00174-18-F-0283.

If not already, units identified in Table 1 shall be marked with the assigned test control number (TCN) to track the items through the test sequence. Photographs (prior to testing) shall be taken to document any non-conformance or damage. Visual inspection results and photographs shall be provided in the Acceptance Test Report.

3.4.2 The bridgewire resistance test shall be conducted on the units two times in accordance with Table 1 and Pacific Scientific ATP TP-93670 section 4.4a. Units shall be tested before and after no-fire testing as required in Table I. Photograph(s) shall be taken of test setup. Bridgewire resistance test results, in ohms, shall be provided the Acceptance Test Report.

3.4.3 The insulation resistance test shall be conducted on the units in Table 1 in accordance with Pacific Scientific ATP TP-93670 section 4.5. Photograph(s) shall be taken of test setup. Insulation resistance test results, in ohms, shall be provided the Acceptance Test Report.

3.4.4 The electrostatic discharge (ESD) test shall be conducted on the units in Table 1 in accordance with Pacific Scientific ATP TP-93670 section 4.6. Photograph(s) shall be taken of test setup. Electrostatic discharge test results shall be provided in the Acceptance Test Report.

3.4.5 The radiographic examination shall be conducted on the units in Table 1 in accordance with Pacific Scientific ATP TP-93670 section 4.8. Radiographic inspection report and copy of X-ray(s) shall be provided in the Acceptance Test Report.

3.5 Functional Testing (Destructive). Testing shall be performed as shown in Table 1. All test data and inspection results shall be recorded and provided in the Acceptance Test Report

(ATR). (CDRL A003)

3.5.1 The no-fire test shall be conducted on the units in Table 1 in accordance with Pacific Scientific ATP TP-93670 section 5.3. Photograph(s) shall be taken of test setup. No-fire test results and, if applicable, associated non-conformance reports, shall be provided in the Acceptance Test Report.

3.5.2 Prior to functional testing, the units shall be temperature conditioned and then functionally tested in accordance with Table 1 and ATP TP-93670 sections 5.4 and 5.5.

Photograph(s) shall be taken of test setup.
