Treatment shall be completel

10、y dry. All shipments over 100 pieces should be shipped so that the pieces are placed and held in a vertical position during transit and storage, and must be sound when received. Light colored dusting powders are objectionable. 3.3 PERFORMANCE TESTS 3.3.1 Water Absorption Test Weight Increase, max 35

11、 % Test Method: A 6.0 in (152 mm) piece of loom shall be totally immersed in water at 23 +/- 2 C for 24 h, then blown out with a mild air current. Measure the weight increase immediately after removing the water. ENGINEERING MATERIAL SPECIFICATIONESB-M3L38-APrinted copies are uncontrolled Copyright

12、2005, Ford Global Technologies, LLC Page 3 of 3 3.3.2 Tensile Strength A 6.0 in (152 mm) piece of loom, measured between supports, shall be capable of standing a tension test for 5 min without breaking or opening at any point as required in the following table. Nominal Tensile Strength, Size, in lb

13、(N), min 1/8 & 5/32 65 (290) 3/16 75 (334) 1/4 85 (378) 5/16 & 3/8 100 (445) 7/16 or larger 150 (668) 3.3.3 Pinch Test The material in the wall of the loom shall not crack or break when a 3.0 in (76 mm) length is flattened between 2 steel plates. When the inside diameter of loom is 3/8 in (9.53 mm)

14、or smaller, the distance between plates is to be 11/64 in (4.37 mm). When the inside diameter of loom is over 3/8 in (9.53 mm), the distance between plates is to be 9/32 in (7.14 mm). The finish shall not show excessive cracking when loom is subjected to the test. 3.3.4 Bend Test The wall shall not

15、collapse when the loom is bent at 23 +/- 2 C to a radius of 5 times its inside diameter. The compound and finish shall not crack open in this test. 3.4 FLAME TEST Shall not support combustion for longer than a 1 min period. Test Method: Apply five 15 s applications of a standard test flame with inte

16、rvals of 15 s between applications. A standard test flame is the blue flame, about 5 in (127 mm) high, produced by a 1/2 in (12.7 mm) Bunsen burner fed with ordinary illuminating gas at normal pressure. The nonmetallic cable conduit shall be held vertically with either the lower or the upper end thoroughly sealed to prevent the passage of air. The flame must be applied horizontally.
