29、stness to crocking equal to or better than the standard sample or shall show and AATCC Chromatic Transference Scale rating not lower than 3.5 for each of the pattern areas except Black 357 which shall show and AATCC Chromatic Transference Scale rating not lower than 1.5. Testing shall be as specifie

30、d in 4.4.3. 3.5 Pattern execution, class 5. The pattern shall match the standard sample with respect to design, colors and registration of the respective areas. Each pattern area shall show solid coverage; skitter ness exceeding that shown by the standard sample in any of the printed areas wil not b

31、e acceptable. The pattern repeat of the camouflage printed finished cloth shall be 27.25 +1.25 -2.5 inches.
