Thespecimen shall be prepared for test by cutting the coating, or film through to the cloth on twoparallel cuts one inch apart with the cuts running the length of the specimen; the
15、 cuts shall beapproximately 1/2 inch from each edge of the specimen. At one end of the specimen, a bias cut ofthe coating, or film through to the cloth shall be made from one of the parallel cuts to the other.The coating, or film shall then be separated by hand for a distance of 2 inches starting at
16、 the pointformed by the cuts; the coating strip shall be 1 inch wide.Clamp the bias cut end of the test specimen in one clamp of the testing machine and the one inchstrip of separated coating in the other clamp. Separate the coating, or film from the cloth for adistance of 3 inches in accordance wit
17、h ASTM-D-751, Adhesion of Coating to Fabric, using apulling clamp speed of 5 mm/sec (12 inches/min). The adhesion shall be the average of the fivehighest peaks of force for the one inch wide strip of coating, or film separation; the result reportedshall be the coating strip adhesion mathematically c

20、Blocking. ASTM D 751, Blocking Resistance at Elevated Temperatures, except that the testshall be performed at a temperature of 1800+ 2oF for 30 minutes. Evaluate the resistance of thespecimen to blocking by the scale given below:1 - No Blocking. Cloth surfaces are free and separate without anyeviden
21、ce of cohesion or adhesion.2 - Trace Blocking. Cloth surfaces show slight cohesion or adhesion.3 - Slight Blocking. Cloth surfaces must be lightly peeled to separate.4 - Blocking. Cloth surfaces separate with difficulty or coating, or film is removedduring separation.3.9 Elongation (applicable to cl
22、asses 4, 7, 9 and 10 only). The elongation test shall be conductedin the following manner:Cut a 3 by 9-inch specimen from the center section of the finished cloth with the long dimensionof the specimen parallel to the direction of the finished cloth being tested. Mark off a 3-inch longProvided by IH
23、SNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-595177section in the center of the specimen. Clamp one end of the specimen in a fixed clamp such thatthe specimen will hang vertically. Clamp a 27-pound weight to the other end of the specimen andsuspend it verti
24、cally for 10 minutes. Before removing the weight, measure the increase in lengthof the 3-inch section and calculate the percent elongation based on the original 3-inch section.One specimen shall be tested unless it fails to meet the specification requirement; in this case,three additional specimens
25、from the sample unit shall be tested and the percent elongation of thesample unit shall then be computed as the average value obtained from testing the four specimens.3.10 Hydrostatic resistance. ASTM D 751, Hydrostatic Resistance, Procedure A (Mullen TypeTester), Procedure 1 with water pressure app
26、lied to the coated, or film side of the cloth.3.11 Cold resistance. The test specimen of finished cloth shall be 8-inches by 8-inches with edgesoriented parallel to the warp and filling directions of the finished coated cloth. The specimen shallbe exposed in a low temperature chamber at a temperatur
27、e of minus 20o + 2oF for two hours.Without removal from the chamber, the specimen shall be creased 180o in the center in the warpand filling directions respectively by folding slightly on a flat, smooth surface and running thecenter of a steel roller over the fold a single time. The steel roller sha
28、ll be approximately 2 incheswide and shall weigh 10 pounds except for coated cloth Classes 1,2,3 and 7, which shall weigh 5pounds. The specimen shall be opened between the two creasing operations. The pressure on thespecimen shall be the weight of the roller. The temperature of the roller shall be t
29、he same as thatof the specimen. The specimen shall be handled with gloves and care taken that its temperatureremains uniform throughout the test. The specimen shall be so folded, in both warpwise andfillingwise directions that the coating or film shall be on the outside of the fold. The specimenshal
30、l be removed from the chamber and visually examined for signs of coating, or film cracking orflaking. One specimen shall be tested per sample unit.3.12 Plasticizer loss ASTM D-1203, Test Method A, except that the test temperature shall be104oC +2oC.3.13 Toxicity assessment. The contractor must furni
31、sh information which certifies that thefinished product is composed of materials which have been safely used commercially or providesufficient toxicity data to show compatibility with prolonged, direct skin contact. At a minimum,toxicity data should include results from a primary dermal irritation s
32、tudy in laboratory animalsand a repeated insult human patch test (Modified Draize Procedure). The latter must beconducted under the supervision of a qualified dermatologist using at least 100 free livingindividuals.3.14 Mildew resistance. AATCC 30, Test 1, shall be performed for a 12-week exposure t
33、ime. Aminimum of five specimens shall be tested. As an alternate AATCC 30, Test III may be used. Thesoil shall be made of an equal blend of good topsoil, well-rotted and shredded manure and coarsesand. Determination of the breaking strength after mildew exposure shall be in accordance withASTM D 503
34、4 (G-E or G-T).3.15 Oil resistance. Place an 8 by 8-inch specimen of the finished cloth, with coated, or film sideup, on a wood frame with inside dimensions of 6 inches by 6 inches by 1 inch deep. Force thespecimen into the frame using a wooden block of dimensions 5-3/4 inches by 5-3/4 inches by3/4
35、inch thick with rounded corners to form a basin of uniform depth. Tack the edges of theProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-595178specimen to the frame and remove the block. Pour oil conforming to Oil No. 1 of ASTM D 471into the basin
