This FOTP is from TIA Standards Proposal No. 3854, formulated under
24、the cognizance of TIA FO-6.7, Subcommittee on Fiber Optic Cable. This FOTP is part of the series of test procedures included within Recommended Standard TINEIA-455.

26、ptic cable on a reel, drum, or spool, to withstand elevated temperature for prolonged periods of time without sticking to itself on adjacent turns or layers. 2 Normative references The following documents form a part of this FOTP to the extent specified herein: EIA/TIA-455-A, Standard test procedure
27、s for fiber optic fibers, cables, transducers, sensors, connecting and terminating devices, and other fiber optic components, FOTP-13 (EIA-455-13), Visual and mechanical inspection of fibers, cables, connectors and/or other fiber optic devices. 1 STDSEIA TIA-455-BqB-ENGL 1772 E 3234b00 Ob14355 2b5 T
28、INEIA-455-84B 3 Apparatus The following apparatus and equipment is required to perform this test: 3.1 Metal spool Use a metal spool which has a barrel or drum diameter of 30 to 50 times the outside diameter of the fiber optic cable under test. The flanges of the spool shall be such that the ends of
29、the cable specimen can be attached to them. 3.2 Chamber Use a test chamber with a volume of sufficient size such that the specimen within it will not interfere with the generation and maintenance of the prescribed test conditions. The heat source shall be located such that the radiant heat will not
30、fall directly on the specimen. 3.3 Temperature probe Unless othewise specified, use thermocouples or equivalent temperature sensors to determine the temperature within the chamber and to control the chamber temperature. 2 4 Sampling and specimens TINEiA-455-84B The test specimen shall be a represent
31、ative sample of a completed fiber optic cable. Specimen length shall be at least 1,500 times the finished diameter of the cable (see 5.2). 5 Procedure 5.1 Attach one end of the cable specimen to the spool. 5.2 Wind three layers of the specimen cable on the spool drum with a minimum of three close tu
32、rns in each layer such that the wind arrangement is mechanically stable. Excercise care to ensure that the individual turns are in intimate contact with the adjacent turns. Winding tension shall be uniform and sufficient to ensure intimate contact on the spool. Minimum winding tension shall be 10 N
33、(2.25 Ibf). 5.3 After winding, attach the remaining (outside) end of the specimen to the spool and secure it in such a manner as to ensure that no unwinding or loosening of the specimen can occur 5.4 Place the spooled specimen in the test chamber. Unless otherwise specified in the Detail Specificati
34、on, maintain the temperature of the chamber at 71 5 2 OC for a period of 48 hours. 5.5 After temperature conditioning has been completed, remover the spooled specimen from the chamber and allow it to return to room temperature. (In case of dispute, refer to the standard atmospheric conditions of EIN
35、TIA-455-A.) 5.6 After the spool has stabilized at room ambient, manually unwind the entire cable specimen from the spool while evaluating it for any unwinding difficulty, and while visually examining for evidence of adhesion (blocking) of adjacent turns. Refer to FOTP-I 3, but note that magnificatio
36、n is not required except in case of dispute. 3 TINEIA-455-846 6 Calculations or interpretation of results 6.1 Calculations No calculations are required by this procedure. 6.2 Interpretation Interpret and report the extent of adhesion according to the following criteria: CRITERIA CLASSIFACTION CODE O
37、BSERVEDRESULTS OF ADHESION A No Adhesion None B C D 6.3 Precision and bias Specimen easily removed. Mild Cosmetic damage only. Specimen removed with some Moderate difficulty. Slight damage consisting, for example, of pieces of the covering (cable jacket) removed so that the cross-sectional area of t
38、he cable is altered, but not to such a degree that the cable core is exposed. The functional integrity of the cable is not jeopardized. Specimen cannot be removed Severe (unwound) without catastrophic damage (for example, cable core exposed). The functional integrity of the cable Ueopardized. The pr
39、ecision of this test has not been determined. No statement can be made about the bias of this test for jacket self adhesion since the result merely states whether there is conformance to the criteria for success specified in the procedure or Detail Specification. 4 STD-EIA TIA-455-84B-ENGL 1792 3234
