27、ation) are flammable or may constitute health hazards, or both. Test temperatures shall be at least 10C below the flash point of any fluid being used. Proper precautions shall be observed during handling and during the balance of the test. Chronic, prolonged or excess exposure to solvents such as Fr

It is recommended that the order in which a particular specimen was removed from the sample be indicated and that each specimen be consecutively numbered. Mark one end of each specimen and

36、measure the diameter of each cable component at 200 mm (7.9 in.) intervals to provide a statistical average for comparison after the samples are aged in the test fluids. Cable end caps shall be placed on each unterminated end of each cable test sample prior to immersion. Determine the weight of each

37、 specimen to the nearest 0.01 gram before that specimen is placed in the test fluid.
