The water-vapor transmission rate shall be measured in accordance with ASTM-F1249, using 100 percent relative humidity on one side of the film and flowing, dry detector gas (nominally, 99.7 percent nitrogen) on the opposite side. The oxygen transmission rate shall be tested in accordance with ASTM-D3985 at 73 ± 1°F (23 ±0.5 °C), at less than 1 percent relative humidity, using no less than 99.9 percent oxygen on one side of the film and a flowing, oxygen-free detector gas (nominally, 98 percent nitrogen and 2% hydrogen) on the opposite side. 4.4.3 Tensile breaking factor and elongation. The barrier material shall be tested for tensile breaking factor and elongation in accordance with ASTM-D882. 4.4.4 Tear strength. The barrier material tear strength properties shall be tested in accordance with ASTM-D5733, determining both peak load and energy to break. Energy to break shall be obtained by measuring the area under the position (inches)/ load (lbs) curve. 4.4.5 Puncture resistance. Puncture resistance shall be determined in accordance with MIL-STD-3010, test method 2065. Five specimens shall be tested with the bag interior side up. 4.4.6 Heat seal strength. The heat seal strength shall be tested in accordance with ASTM-F88 determining both peak load and energy to break. Energy to break shall be obtained by measuring the area under the position (inches)/ load (lbs) curve. MIL-DTL-29597C (NAVY) w/AMENDMENT 1 8 4.4.7 Adhesive seal strength. The peel adhesion shall be tested in accordance with ASTM-F88, using a 15 minute dwell prior to testing. After separation, the strips shall be carefully resealed and the test repeated. 4.4.8. Adhesive seal integrity. The adhesive seal shall be tested as follows. Close the top of the bag securely using the PSA strip. Clamp the full width of the bottom of the bag, invert the clamped bag, and suspend it so that the clamps are level and the top of the bag hangs free. Make a small hole in the side of the bag near the clamps and add enough solution 0.1 percent Aerosol OT with a small amount of red dye so that the water depth is 2 to 2.5 inches and uniform across the bag width. After 15 minutes, the bag shall be tested for leakage by lightly touching a white laboratory tissue to all parts of the sealed area. 4.4.9 Relaxation modulus ratio. Relaxation modulus ratio shall be tested at 70 ºC with a strain of 25 percent using a constant strain rheometer with parallel plate in shear mode. The relaxation modulus ratio shall be calculated by dividing relaxation modulus at 300 seconds by the relaxation modulus at 0.1 second. 4.4.10 Adhesive areal weight. The weight of the adhesive shall be not less than 29 and not greater than 35 grains/24 square inches, when tested as specified in ASTM-D898. 4.4.11 Odor barrier effectiveness. 4.4.11.1 Odor substrates. Three odor substrates (generators) shall be used: a. Raw salmon fish (aged a minimum of 3 days at room temperature) b. Raw chicken (aged a minimum of 3 days at room temperature) c. Milk (aged a minimum of 1 week at room temperature) 4.4.11.2. Sample preparation. Prepare two 3.5 x 3.5-inch bags for each substrate by heat sealing three sides (bag heat seals shall meet the requirements of table I.) Fold a laboratory grade tissue (15 by 17 inches) to 2 square inches. Add 0.5 to 1 gram of a substrate to the center of the folded tissue. Fold the tissue once more to cover the substrate. Place the tissue in the bag and heat-seal the opening. Place the sealed bag in a one quart laboratory jar. The jar shall be tightly closed using a foil lined plastic lid. 4.4.11.3 Procedure and evaluation. The closed jars shall be placed in an oven maintained at 95 ± 2 °F (35 ± 1 °C). After 60 days, the jars shall be removed from the oven, each bag shall be transferred to a clean jar and replaced in the oven, except for the aged milk bag, which shall be allowed to remain at room temperature. After one hour, observe the odor in one jar for each substrate by lifting only one side of the lid (keeping the other in contact with the jar) and immediately placing the nose in the opening. Odor shall be graded as: 0 - No odor 1 - Faint, unobjectionable odor 2 - Moderate odor 3 - Strong odor The odor of the plastic bag itself shall not be considered objectionable. MIL-DTL-29597C (NAVY) w/AMENDMENT 1 9 4.4.12 Material compatibility. Barrier material samples shall be immersed in the following fluids for 7 days at 68 ± 5 ºF (20 ± 3 ºC): a. Cleaning solvent in accordance with MIL-PRF-680, type II. b. Hydraulic fluid in accordance with MIL-PRF-83282. c. JP-8 grade kerosene in accordance with MIL-DTL-5624. After immersion, samples shall be visually examined and then tested for tensile breaking factor, elongation, and tear strength properties. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or inhouse contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activities within the Military Service or Defense Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. The bags provide an odor barrier for the containment of foodcontaminated plastic waste in shipboard applications where at-sea disposal of plastics is prohibited. There are no commercial equivalents that meet all of the physical and mechanical requirements necessary for this application. In use, filled bags are intended to remain aboard ship for prolonged periods of time in consonance with naval deployments. Type I bags are to be used by surface ships for containment of plastic waste processed plastic disks and loose plastic waste material prior to disposal. Type II bags are for use in submarine compaction units. 6.2 Acquisition requirements. Acquisition documents should specify the following: a. Title, number, and date of this specification. b. Bag type and class (see 1.2). c. Bag size and quantity (see 1.3). d. Rolls or packaged individual bags. e. When first article is required (3.1). f. Packaging requirements (see 5.1). 6.3 First article. The contracting officer should provide specific guidance to offerors whether the first article samples should be a pre-production item, a first production item, a sample selected from the first production items or a standard production item from the MIL-DTL-29597C (NAVY) w/AMENDMENT 1 10 contractor’s current inventory (see 3.1 and 4.2). The contracting officer should also include specific instructions in acquisition documents regarding arrangements for submission of Material Safety Data Sheets (MSDS) prior to contract award, testing, approval of first article test results, and disposition of first articles. Invitations for bids should provide that the Government reserves the right to waive requirements for first article inspection to those bidders offering a product, which has been previously acquired or tested by the Government. Bidders offering such products, that wish to rely on such production or test, must furnish evidence with the bid that the prior Government approval is acceptable for the pending contract. Bidders should not submit alternate bids unless specifically requested to do so in the solicitation. 6.3.1 Prior approval. If a contractor has previously delivered an acceptable product meeting the requirements of this specification, waiver of the first article inspection requirement (see 4.2) is at the discretion of the procuring activity for a period of time not to exceed 2 years (see 6.2). 6.3.2 First article sample. The first article sample should be produced using the same plant facilities intended for the production run. Failure of the first article sample to meet all the requirements of this specification is cause for rejection. 6.4 Cross reference.
