3.1 SALIENT CHARACTERISTICS

Design. The Adjustable Retention System shall consist of a 4-point retention system, 3.1.1 with a nape pad, which can be installed in a Maritime Security Helmet (MSH) without bolts.

The Adjustable Retention System shall be one (preferred) or two sizes and be compatible with the MSH shell (including standard 7-pad suspension system), built in accordance with NQ/PD 16-02. The retention system shall use an open cup for the chin and a side release buckle to secure the retention system to the user. The retention system shall be replaceable and adjustable for quick sizing adjustment via straps and a ratcheting/locking headband with a knob/dial. Once adjusted, the system shall resist loosening.

Materials and components. The materials and components shall conform to applicable 3.1.2 specifications, standards, and drawings required herein unless otherwise noted in the contract or solicitation.

Nape pad. The nape pad shall consist of a pouch enclosing foam padding and an 3.1.3 additional outer fabric layer. The inner layer and outer layer of material shall be black in color.

Side release buckle set. The side release buckle set shall be Acetal for the male 3.1.4 component, Acetal for the female component, and shall be Black in color. The buckle must require two separate input forces in different directions in order for it to release (like squeezing) so that it cannot be accidentally released if inadvertently pressed or pulled in a single direction.

The buckle design should be such that the features that are used to release the buckle are shaped and protected in such a way as to not allow inadvertent release when bumping into other objects.

The buckle must be shaped in such a way to allow convenient attachment and release of the retention system while wearing gloves for donning and doffing the helmet.

Headband. The headband subsystem shall consist of a knob/dial and a strap/band of 3.1.5 adjustable length wrapping around the back and sides of the user’s head. The knob/dial shall incrementally reduce the size of the head band strap through a ratcheting/locking mechanism.

Fit. TheAdjustable Retention System will be designed to fit personnel within the 5th to 3.1.6 95th percentile per the 2012 Anthropometric Survey of Army personnel (ANUSR II) data. A properly fitting helmet will meet the following criteria:

3.1.6.1 The head touches the crown pad.

3.1.6.2 The helmet shell is not more than ½ inch (12.5 mm) above eyebrow.

3.1.6.3 The helmet shell offset is ≥ ½ inch (12.5mm) (center forehead used)

3.1.6.4 The helmet shell is no more than ½ inch (12.5mm) above the ear canal.

3.1.6.5 The helmet is able to be securely mounted to preclude lateral or vertical movement.

Integration/Compatibility. The Adjustable Retention System must be compatible with the 3.1.7 following current/planned US Navy equipment:

3.1.7.1 M50 Joint Service General Purpose Gas Mask

3.1.7.2 Naval Security Forces Vest (NSFV) Armor System per NQ/PD 10-01 with yoke/collar installed.

3.1.7.3 3M/Peltor COMTAC communications headset with neck band.

3.2 Construction.

Workmanship. Utmost care shall be taken during fabrication to ensure quality 3.2.1 workmanship and safety of the service person using the item.

Thread Ends. Thread breaks or bobbin run-outs occurring during sewing shall be secured 3.2.2 by stitching back of the break a minimum of ½ inch. Thread tension shall be maintained so that there will be no loose stitching resulting in loose bobbin or top thread, or excessively high stitching resulting in puckering of the materials sewn. Thread ends shall be trimmed to a length of not more than ¼ inch.

3.3 Operating requirements.

Intended use. The Adjustable retention system shall allow the user to easily don and doff 3.3.1 the helmet and provide adjustment to allow for proper fit of the helmet in accordance with this document and NQ/PD 16-02.

Adjustment. The Adjustable retention system must allow for quick and convenient 3.3.2 adjustment of its size and level of tightness with one or both hands. When using one hand, the desired objective is that it takes less than two seconds per strap and less that two seconds to adjust the ratcheting headband, and while using two hands, the desired objective is that it takes less than five seconds to properly adjust all four helmet straps and the ratcheting headband. This capability must also be possible while wearing gloves. Adjustment time assumes the helmet is stored with the straps and headband loosened to their maximum length.

Strength. The retention system must meet the following strength requirements when 3.3.3 installed in a MSHin accordance with NQ/PD 16-02.

Static pull strength. No component of the retention system shall fail, the retention system 3.3.4 closure device shall not release (open), and the webbings shall not slip when subjected to a load of 150 lb when tested in accordance with 4.4.4.

Dynamic pull strength. No component of the retention system shall fail when subjected 3.3.5 to a 25 ft/sec drop when tested in accordance with paragraph 4.4.5.

4. PRODUCT CONFORMANCE

4.1 Classification of testing. The testing requirements specified herein are classified as follows:

a. First Article Testing (FAT) (see 4.2)

b. Lot Acceptance Testing (LAT) (see 4.3)

Certificate of conformance. When Certificates of Conformance (COC) are submitted, the 4.1.1

Government reserves the right to inspect such items to determine the validity of the certification.

Conformance shall be verified by test, inspection, demonstration, or analysis, on the end item assembly or lower level as appropriate. Supporting data will be available for Government review.

4.2 First article testing (FAT). When specified in contract purchase order, complete Adjustable Retention Systems samples, representing full production quantity, shall be subjected to FAT in accordance with 4.4.1 through 4.4.7.

Material qualification. At any point after FAT has been approved, any desired material 4.2.1 change must first be properly communicated to and authorized by the Government. It must be tested in accordance with the appropriate paragraphs of this commercial item description and approved by the Government.

4.3 Lot acceptance testing. Lot acceptance testing shall be conducted on each lot of Retention Systems prior to delivery. A LAT shall consist of conformance inspection of the retention system end item.

4.4 Requirements and verifications.

Visual examination. The retention system shall be visually examined for compliance to 4.4.1 all of the requirements of referenced documents unless otherwise specified. The retention system shall be examined for the defects listed in Annex A, Table I.

Dimensional examination. The completed retention system or individual components 4.4.2 shall be examined for defects listed in Annex A, Table II.

Component and end item testing. The government reserves the right to inspect all 4.4.3 components and end items to determine conformance to requirements.

Static pull strength test. The retention system pull test shall be tested with a testing 4.4.4 machine that is in conformance with ASTM-E-4, “Practices for Force Verification of Testing Machines” or that specified in DOT FMVSS 218. The helmet shall be rigidly attached to the testing machine base with either a clamp or headform device. The retention system shall be attached to a grip that simulates the jaw. The grip shall consist of freely-moving cylindrical rollers, each 0.25 inch radius, and rigidly spaced 3.0 inch apart (center-to-center) with a length of approximately 1.50-inch to accommodate the retention system chin-up (DOT FMVSS 218, Figure 4, for set-up).

The retention system pull test shall be tested as follows:

a) Mount the helmet in the test fixture. Use a suitable means to mark the retention system webbing ends at the attachment hardware points.

b) Apply a load at the rate of 1.0 (± 0.10) –inch/minute until a minimum 150-lb load is achieved. Hold the 150-lb for a minimum of 1 minute.

c) Inspect the retention system for failure as specified in 3.3.4 within 5 minutes of completing the 150 lb load for 1 minute. Use the marks on the webbing (see step a) to determine slippage. It should be noted that the retention system is allowed to stretch, but not slip (loosen). Failure to meet the requirements of 3.3.4 shall constitute test failure.

d) For information purposes only, continue applying a load to the retention system at a rate of 1.0 inch/minute until the retention system fails. Record the peak load as the pull strength and identify / record the mode of failure.

Dynamic pull strength test. Mount the finished helmet on the apparatus in accordance 4.4.5 with 4.9.14 of NQ/PD 16-02. The helmet shall be dropped at 25 ft/sec onto a hemispherical anvil once on each of the locations in accordance with 4.9.13 of NQ/PD 16-02.
