A6 Test Procedure B-328.pdf

This is a test procedure document (B-328) for verifying and testing the DIN Regulator PIT on the NSWC PCD SEAL Delivery Vehicle. The procedure was prepared by NSWC PCD Code E12 and requires NAVSEA approval.

The document outlines specific procedures for testing the Poseidon Xstream Deep MK3 Regulator (P/N 8437059-1), including regulator output pressure verification and tightness testing. Key testing requirements include verifying/setting regulator output pressure between 130-140 psig with an input pressure of 3,000-4,000 psig, and conducting tightness verification by immersing the regulator in clean water for 5 minutes with no allowable leaks. The procedure requires calibrated pressure gauges with ±0.5% accuracy, clean connecting air hoses and fittings, and compliance with safety procedures including wearing safety glasses when working with compressed air. The test requires only a Test Conductor and Reviewer, with QC inspection being marked as "Not Required."
