Thickness of the film shall be determined in accordance with ASIM D 374, method A or C. For films with a nominal thickness

30、 of 0.00015, 0.00025, and 0.00035-inch, the thickness shall be measured by the above method; however, the film shall be built up by using the number of plies specified below and dividing the readings by the number of plies used.

The average of the 10 readings shall fall within the specified limits. 4.3.3 Dimensional stability, tvDe I, II, III, and V films. The film shrinkage shall be determined on five specimens c

32、onditioned according to 4.3.1 before and after test. The specimens shall be 10 inches by 10 inches by width of slit roll if this dimension is less than 10 inches. Three masurements shall be made in the longitudinal direction (machine direction) and in the transverse direction. All measurements shall

33、 be accurate to 1/32 inch. Specimens shall be tested by freely suspending them in an oven controlled to 150C _+ l0C for type II and V film and 2OO0C _+ l0C for type I and III film. The test period shall be 30 minutes. Specimens are to be cooled and conditioned in accordance with 4.3.1 before measure

34、ments are made. The percent shrinkage shall be canputed fran the 3 measurement average before and after test. 12 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-L-P-377C W 9999974 CIL63858 LLL W L-P-377c shall be determined on five specimens conditio

35、ned in accordance with 4.3.1. 4.3.3.1 Dimensional stability, tvpe IV film only. TLpe IV film shrinkage Before testing, the specimens shall be 1/4 inch by 15 inches and cut so that the long dimension is parallel to the longitudinal direction (machine direction) of the film. Mark a pair of lines 12 in

36、ches apart on each sample. Measure the distance between the lines on specimens conditioned according to 4.3.1 to the nearest O. O1 inch before and after test. Specimens shall be tested by placing a paper clip conforming to Gem pattern, type I, A-A-2601, capacity 1/16 inch at each end and freely susp

37、ending the assembly in an oven controlled to 15OoC _+ 1 OC. The test period shall be five minutes. The percent shrinkage shall be canputed fran the 5 measurement average before and after test. 4.3.3.2 Dimensional stability, tiwe VI film only. Five specimens 5 inches by 5 inches shall be measured to

38、the nearest 0.1 inch and them imnersed in boiling water ( 100C) for 30 seconds. Remove, cool, lay flat, and smooth out wrinkles. Measure the samples to the nearest 0.1 inch. The percent shrinkage shall be calculated as follows: (Original dimension - Final dimension) X 100 = percent shrinkage Origina

39、l dimension 4.3.4 Optical transmittance, type V film only. The optical transmittance shall be determined in accordance with the following procedure. The test equipnt shall be a Bausch E, Imb Spectronic “20“ Colorimeter or equivalent. Five test specimens, randcanly selected fran the roll, shall be cu

40、t to 3/4 inch by 2 inches. The procedure is to allow the instrument to warm up. The wavelength control shall be set to 400 millimicrons. Adjust the instrument to read zero transmittance. Insert an mpty specimen holder into the 1 inch test tube adapter and adjust the needle to read 100 percent transm

41、ittance. Place a specimen between the holder halves and read percent transmittance. 5. PACKAGING 5.1 Preservation.
