It is the responsibility of whomever uses this proc
26、edure to establish appropriate safety practices and to determine the applicability of regulatory limitations prior to use.

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
28、eon TMC, 1-1-1 Trichloroethane, Methylene Chloride, and Methyl Isobutyl Ketone may act as a carcinogen or damage internal organs. Use such test fluids only in a well ventilated area (use of a gas mask may be advisable) and avoid skin contact as a standard precaution. Test personnel should consult sa
29、fety data sheets for such materials. 5.0 TEST SAMPLE 5.1 Fiber Optic Cable Unless otherwise specified in the Detail Specification, the test sample for the Cable Test shall be a representative sample of a completed fiber optic cable.

PROCEDURE 6.1 Pre-immersion Examination of all Samples Visually examine samples in accordance with the requirements of FOTP-13, checking for defects (e.g., chips, cracks, tears, loose or missing parts, improper lubrication, improper assembly
34、and unmateability) that might unfairly bias the test results. Samples deemed not to be suitable for test (e.g., worn, physical defects, other degradation) shall be replaced prior to testing. 6.2 Pre-immersion Preparations - Cable Samples 6.2.1 6.2.2 6.2.3 6.2.4 Cable specimens to be immersed in each
35、 test fluid shall be cut from a single cable sample and labeled as to the fluid in which it is to be immersed. 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.
