The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.2).
27、b. Conformance inspection (see 4.3). 4.2 First article inspection. When a first article is required (see 6.2) it shall be examined for the defects listed in 4.3.1 and shall be tested for the characteristics specified in Table III. 4.3 Conformance inwection. Sampling for inspection shall be as specif
28、ied in the contract or purchase order. 4.3.1 End item examination. 4.3.1.1 Yard by yard examination. During the yard by yard examination, each roll in the sample shall be examined on one side only for the defects listed below. However, the side of the cloth examined shall be alternated on every othe
29、r roll. The same yardage shall be given a through- lighting inspection for pinholes and for thin areas in accordance with MIL-STD-1487. All defects found shall be counted regardless of their proximity to each other, except where two or more defects represent a single local condition of the cloth, in
30、 which case only the more serious defect shall be counted. The sample unit shall be one linear yard. An approximate equal number of yards shall be examined from each roll in the sample. I I Classification I - I/ Odors of chemicals or commonly used finishes adjust to achieve required relative humidit
31、y (see e. above). g. The test specimens shall fit smoothly on the specimen rack of the apparatus with no, wrinkles or gaps. The test specimen shall be mounted to the outside of the rack with the use of appropriate stainless steel spring clips. After the required exposure period, the specimens shall
32、be removed from the apparatus and allowed to dry and condition at Standard Conditions. Then test specimens for each required test shall be cut and tested appropriately. NOTE: Monitoring of dry bulb temperature, wet bulb depression, irradiance, and black panel temperature is recommended through the u
33、se of chart recorders. 4.4.5 Flame resistance. Method 5903 of FED-STD-191 except that five specimens shall be tested in the warp direction only. In addition to after flame time and char length, any evidence of flaming, melted or molten pieces dropping from the specimen at any time during the test sh
34、all be reported. 4.4.6 Stiffness. 4.4.6.1 TAPPI Method T-45 1, Preferred Procedure (i), except that five test specimens with the long dimension parallel to the warp direction of the finished cloth shall be tested and the standard textile test conditions as specified in ASTM D-1776 shall be used. 4.4
35、.6.2 The stiffness test shall be conducted as specified in 4.4.6.1 except that the apparatus and test specimens shall be subjected to a temperature of -20F e.g., magnesium oxide, or vitrolite tiles. The spectral band width at 860 nm shall be less than 26 nm. Reflectance measurements shall be made by
36、 either the monochromatic or polychromatic mode of operation. When the polychromatic mode is used, the spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a continuous source that simulates either CIE Source A or CIE Source D65. The specimen shall be mea
37、sured as a single layer backed with two layers of the same fabric and shade. Measurements shall be taken on a minimum of two different areas, and the data averaged. The measurement areas should be at least 6 inches away from the edges of the finished cloth. The specimen shall be viewed at an angle n
38、o greater than 10“ from normal, with the specular component included. Photometric accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within 2 nm. The standard aperture size used in the color measurement device shall be 1 .O to 1.25 inches in diameter. Any color havin
39、g spectral reflectance values falling outside the limits at four or more of the wavelengths specified in 3.7 shall be considered a test failure. 4.4.1 1 Toxicitv assessment. The cloth shall be tested for toxicity as follows: a) Title 40, Code of Federal Regulations, 1994 Edition; Section 798.4 100-
40、Dermal Sensitization Section 798.4470- Primary Dermal Irritation Section 798.4500- Primary Eye Irritation Marzulli, F. & H. Maibach, “Contact Allergy: Predictive Testing in Humans“, Advances in Modem Toxicology, Volume 4, pp 353-372, 1977. b) As an alternative to animal and human testing, the contra
41、ctor may provide information which certifies that the finished product was composed of chemicals or materials which have been safely used commercially where prolonged skin contact has occurred. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
42、the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging ac
43、tivity within the Military Department System Command. 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.
