The frequency of Sampling B tests are determined by the number of weld setups that occur during the production of the contract quantities. Sampling is performed at the beginning and end of each welding process in order to provide assurance of the consistency of the process and thus the conformance of the welds created during the process.

7.1.4. Sampling C Tests: Bladder Dimensional Inspection

The frequency of Sampling C tests is to be done once per size of CSU-22/P and once per size of CSU-23/P. If there is no change in size or style per lot, a sampling will be performed every 50 suits.

7.2. Master List –Production Test and Inspection

The following tests and inspections are performed as verification that the individual trousers and lot of trousers conforms to the critical requirements during the production stage. Refer to section 9 for details of tests and inspections.

Acceptance tests during the production stage are to be conducted either as an individual test or as a sampling test. Individual tests are conducted on each trouser while sampling tests are conducted at chosen intervals within the production process.

10.2. Basis for Rejection

10.2.1. Individual Test Rejection

When any trouser fails to meet the acceptance criteria during individual test, the trouser shall be rejected.

10.2.2. Sampling Test Rejection

When any trouser fails to meet the acceptance criteria during a sampling (lot) test, the individual trouser shall be rejected and the acceptance of the entire production lot shall be withheld until the extent and cause of failure have been determined and communicated to the procuring agency.

10.3. Rejection and Retest

10.3.1. Trouser Repairs

Defects found during in-process and conformance testing can be reworked to meet the original specification as long as the repair method is feasible and does not cause additional damage to the suit. The result of this rework shall not degrade the performance or physical appearance of the trousers. Rework of load-bearing seams or stitching defects can only be completed a maximum of twice per location, including during in-process manufacturing, to minimize material degradation. Load-bearing stitching includes, but is not limited to, main suit panel seams, bladder installation stitching, knee darts, all zippers excluding calf pocket zippers, knife pocket installation, lacing installation, secondary restrain buckle installation, and reinforcement installation. All rework shall be recorded under the contractor's nonconformance and corrective action system (Section 11.5). After rework, any previously completed tests deemed as affected by these changes shall be repeated. If rework cannot be completed without damage to the suit, or if the maximum number of allowable reworks would be exceeded, the suit shall be discarded and not sold as part of that or any lot to the US Government.

10.4. Continuation of Test

10.4.1. Test Failures

For production reasons, individual tests or sampling test may be continued pending the investigation of a failure to meet the acceptance criteria. In the case of failures during sampling test (other than endurance), corrective actions can include individual testing of all units within the lot as deemed necessary by the contractor in consultation with the procuring agency. Final acceptance of the entire lot(s) shall not be made until it is deemed that the lot(s) meet all acceptance criteria.

10.4.2. Notification of Test Failure

The procuring agency shall be notified within 24 hours of the failure or end of next business day after 10 or more suits have failed individual testing. In the case of Lot Sampling Failure, the procuring agency shall be notified within 24 hours of the failure or end of next business day. The procuring agency, quality assurance representative or government technical authority has the right to stop production after notification of 10 individual testing failures or lot sampling failure.

10.5. Corrective Action / Failure Analysis

10.5.1. Contractor Nonconformance System

The contractor shall utilize their internal nonconformance and corrective action system to record nonconformances that occur during qualification testing, first article inspection, and the production stages of the acceptance testing. These records shall be made available for viewing by the procuring activity or the designated Quality Assurance Representative.

10.5.2. Failure Analysis Report

Should the procuring agency be notified of a lot sampling failure, or 10 or more individual testing failures, a failure analysis report shall be submitted in accordance with Contractual Contract Data Requirements List (CDRL).

10.5.3. Deviation of Waiver

If a request for deviation or waiver is required to request performance, functionality or design changes, the contractor shall follow the requirements of MIL-STD-193, Appendix E. This request shall be coordinated with the designated Quality Assurance Representative and/or the procurement agency.

Any trouser that has experienced more that 110 inflation test cycles at 11 psi or above shall be deemed as having undergone destructive test. This trouser is not acceptable for shipment against the quantities of serviceable finished end items required by contract unless approved by the procuring agency.

APPENDIX 004-1: SUIT FITTING INSTRUCTIONS

Fitting of ATAGS trousers on the inanimate models shall be accomplished as follows:

Step 1:

The comfort zippers, secondary restraint devices, waist and leg slide fasteners shall be opened. The adjustment laces shall be adequately extended.

Step 2:

Trousers shall then be fitted onto the inanimate test model: See Appendix 006-1, the test model shall be a suitable representative of the size and seated orientation of the pilot for which the suit is designed.

Step 3:

The adjustment laces of the ATAGS trousers shall then be taken up and tied so that the trousers will fit snugly, but not tightly, around the abdomen, thighs and calves.

Step 4:

All slide and snap fasteners on the suit shall be in the fully closed position or fastened.

Unless otherwise indicated, this shall include: the leg fasteners, the waist fastener, the comfort fasteners, secondary restraints and other related snap fasteners.

Note: The secondary restraint strength test requires that one of the leg slide fasteners be open during the test.

APPENDIX 005-1: ANTI G TEST APPARATUS

The Anti G Test Apparatus shall be any apparatus that will provide air to inflate, hold and deflate the trouser as specified in the various performance tests (Such as: leakage testing, endurance testing, inflation testing, etc.). The apparatus shall be capable of delivering air to the suit at a free stream flow rate of 10 cubic feet per minute. The apparatus shall have the ability to monitor the internal pressure of the trouser and time. The apparatus shall incorporate all measures so that fill rate, target pressure and inflation/hold/deflation durations are all achieved as outlined in the various performance test plans.

APPENDIX 006-1: INANIMATE TEST MODELS

The inanimate test models are intended to represent a pilot. Hence the manikin(s) used to test the trousers shall be representative of the orientation of pilot in a seated position and also representative of the size of the pilot for which the suit was designed. The table below can be used as a guideline for determining a suitably sized manikin(s) to represent the size of the pilot for each trouser size.

ATAGS/ATP/TI.03-1: PEEL TEST

1. PURPOSE

This test provides a preliminary indication of the adequacy of the welding process to ensure the weld is of consistent strength through the length of the weld. This test allows the operator to proceed with welding pending the results of the seam adhesion test. (ATP/ATAGS/TI.04a- 1). This is not a mandatory test, but is included as a method to optimize production throughput as necessary.

2. REFERENCE

None

3. REQUIREMENT

3.1. Sample Requirement:

One welded assembly from the current die being utilized in the process.

4. PROCEDURE

4.1. After setup, make a weld hit with the die that is in use.

4.2. Manually pull apart the two layers of material to cause separation at the weld line.

4.3. Observe the weld line to ensure that the coating has adhered to one layer of material and that the base cloth is exposed on the opposite side. This indicates the integrity of the weld is adequate to continue with the welding process.

4.4. Ensure that the corresponding seam adhesion test results are received and reviewed for adequacy to quantitatively confirm the peel test result.

5. BASIS OF ACCEPTABILITY

5.1. Acceptance Criteria:

When manually pulled apart, the entire weld line separates from the base material on one side of the fabric.
