10、all be tested as specified in AATCC Test Method 61, Test 1A, 3 cycles. 1993 AATCC Standard Reference Detergent WOB (without fluorescent whitening agent and without phosphate) shall be used. 4.4.8 Synthetic perspiration test. The specimen, 8 by 8 inches, shall be cut and exposed to synthetic perspira
11、tion as follows: The synthetic perspiration solution shall be made by combining 3.0 grams sodium chloride, 1.0 gram trypticase soy broth powder, 1.0 gram normal propyl propionate, 0.5 gram of liquid lecithin and 500 ml of distilled water. Cover the solution and heat to 50 C, stirring frequently whil
12、e heating. Continue until all ingredients are dissolved. Then, cool the solution to 35 C, remove cover and dispense it immediately with a pipette or other measuring device. Dispense 2 ml of perspiration solution at 35 C onto the center of an 8- by 8- by 1/4 inch glass plate. Place the specimen on th
13、e glass plate with the back side contacting the glass. Dispense an additional 2 ml of the synthetic perspiration solution onto the center of the 15 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32149A specimen. Place a second 8- by 8- by 1/
14、4-inch glass plate on top of the specimen and then place a 4 pound weight on top of the assembly in the center. After 16 hours, remove the specimen (do not rinse) and air dry the specimen before testing as specified in AATCC Test Method 15. 4.4.9 Contamination procedure. The specimen (or specimen ar
15、ea) shall be laid flat, face side up, on a glass plate. Three drops (1ml for sealed samples) of a test liquid, either hydraulic fluid or JP-8 conforming to MIL-DTL-83133, shall be applied to the center of the specimen (or specimen area). A glass plate of the same dimensions shall be placed on the sp
16、ecimen (or specimen area) and a pressure of 0.0625 pounds per square inch (1 pound per square inch for seam sealed samples) of glass plate contact area shall be applied to the assembly. After 16 hours (2 hours for seam sealed samples), remove the specimen (or specimen area) from the assembly and tes
17、t immediately for the required performance property in the center of specimen (or specimen area). For testing the initial condition, the test specimen shall be as specified by the applicable test method. For testing hydrostatic resistance and leakage after laundering, one laundering sample 48 inches
18、 by the full width of the cloth shall be used for each test liquid specified above. Three drops of the test liquid shall be applied to each laundering sample. The face side of the laundering sample shall be marked using a laundry marker pen. The laundering test shall then be conducted in accordance
19、with 4.4.10 for one laundering and drying cycle. After laundering, the specimen areas may be cut from the laundering sample to facilitate performance property testing. Ten specimens shall be tested for each of the initial and the after laundering conditions. 4.4.9.1 Contamination procedure after air
20、craft fluids. The specimen (or specimen area) shall be laid flat, face side up, on a glass plate. One milliliter of JP-8 fuel conforming to MIL-DTL-83133 shall be spread over the middle of the sample, followed by 1 ml of de-icing fluid conforming to SAE-AMS1424. The samples shall then be placed flat
21、 in an air-circulating oven at 50 C for 30 minutes. Remove immediately and test as specified in table IV. 4.4.10 Laundering procedure. Place 2 + 0.2 pounds of the cloth in an automatic washing machine set on permanent press cycle, high water level, and a wash temperature of 100 F. The tolerance for
22、the warm wash temperature shall be +10 F and -0 F. A ballast may be added to equal 2 pounds of cloth. Place 0.5 ounce (14 grams) of AATCC Test Method 135, Standard Reference Detergent (non-phosphate) without optical brighteners into the washer. The duration of each laundering cycle shall be 30 + 5 m
23、inutes. After laundering, place sample and ballast in an automatic tumble dryer set on permanent press cycle that has a temperature of 155 + 5 F, and dry for 30 minutes or until dry. The washer and dryer shall be in accordance with AATCC Test Method 135. 4.4.11 Spectral reflectance. Spectral reflect
24、ance shall be determined on the face side and shall be obtained from 600 to 860 nanometers (nm) at 20 nm intervals on a spectrophotometer (see 6.5) relative to the barium sulfate standard, the preferred white standard. Other white reference materials may be used. If other white reference materials a
25、re used, they shall be calibrated to absolute white, e.g. magnesium oxide or vitrolite tiles (see 6.6). The spectral band width shall be less than 26 nm at 860 nm. Reflectance measurements shall be made by either the monochromatic or polychromatic mode of operation. When the polychromatic mode is us
26、ed, the 16 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32149A spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a source that simulates either CIE source A or CIE source D65. The specimen sh
27、all be measured as a single layer, backed with six layers of the same fabric and shade. Measurements shall be taken on a minimum of two different areas and averaged. The measured areas shall be at least 6 inches away from the selvage. The specimen shall be viewed at an angle no greater than 10 degre
28、es from the normal, with the specular component included. Photometric accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within 2 nm. Spectral reflectance values obtained shall meet the requirements specified in 3.11. 4.4.12 Toxicity. The cloth shall be tested in acc
29、ordance with Environmental Protection Agency Health Effects Test Guidelines OPPTS 870.2500 Acute Dermal Irritation, and OPPTS 870.2600 Skin Sensitization. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When a
30、ctual packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by Inventory Control Points packaging activities within the Military S
31、ervice or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains
32、information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use.
