22、IC COMPONENTS Foreword (This foreword is informative and is not a part of this standard.) This document comes from TIA Standards Proposal No. 3-1790-RV2, formulated under the cognizance of TIA FO-4.2, Subcommittee on Optical Fibers and Cables, and TIA FO-4.3, Subcommittee on Passive Optical Devices
23、and Components. This FOTP was originally published in Recommended Standard RS-455-4 as FOTP-12. It was revised and published as EIA/TIA-455-12A, which also superseded FOTP-40. This FOTP is part of the series of test procedures included within Recommended Standard TIA/EIA-455. There are two Annexes,
24、both informative. Key words: exposure, cable, connector, splash, wet patch, Military ANSI/TIA-455-12B iv This page blank. ANSI/TIA-455-12B 1 FOTP-12 FLUID IMMERSION TEST FOR FIBER OTPIC COMPONENTS 1 Introduction 1.1 Intent The intent of this test is to establish the ability of a fiber optic componen
25、t (cable, connecting device, etc.) to resist degradation when exposed to specific fluids with which the component may come into contact during its service life. (Note: For fluid immersion testing of optical fiber, refer to FOTP-741). The primary tests defined herein are for accelerated aging and con
26、tinuous immersion evaluation by complete immersion of samples for specified times at specified temperatures. A secondary method is defined only for non-Military cables and defines proximity or periodic exposure. This test is a “wet patch” test and is only used if specified by the Detail Specificatio
27、n. 1.2 Failure modes Potential failure modes for this test include, but are not limited to: 1.2.1 Swelling of any materials. (Exception materials that are functionally designed to swell, e.g., swellable water blocking tapes.) 1.2.2 Dimensional changes other than swelling. 1.2.3 Softening of any mate
28、rials. 1.2.4 Loss of seal or adhesive bonding between two bonded surfaces. 1.2.5 Discoloration of materials, finishes, and marking (may or may not be considered detrimental). 1.2.6 Changes in mating and/or coupling characteristics. 1.2.7 Corrosion of any materials, finish peeling, cracking, or flaki
29、ng. 1.2.8 Inability to mate or unmate (connector, device, or cable assembly). 1.2.9 Degradation of cable/connector optical transmission characteristics. 1 FOTP-74 supersedes FOTP-75, Fluid Immersion Test for Optical Waveguide Fibers.

Vessels shall be of sufficient size and fluid capacity to permit the sample(s) under test to be appropriately immersed (complete immersion, in many i
38、nstances) in each fluid selected, without violating other physical constraints (e.g., minimum cable bending radius). Glass vessels shall be rated to withstand the test temperature. 3.2 Prepared immersion fluids 3.2.1 Unless otherwise specified, test fluids to be used shall be those listed in Tables
39、I, II, and III, as applicable: Table I is for cables Table II is for connectors, related devices, and other components; and Table III is for all U.S. Military applications. NOTE The fluids of Table III may be specified for applications other than U.S. Military testing, though that is the primary fun
40、ction. Prepare sufficient quantities of the required fluids to immerse the samples in the vessels to be used. 3.2.2 The use of the proximity exposure test of 6.6.6 requires that the Detail Specification specify the test fluids. Prepare sufficient quantities of the specified fluids in order to carry
41、out ANSI/TIA-455-12B 4 the test of 6.6.6, as indicated by ASTM D 543, Wet Patch Method, Practice B. Fluid temperatures shall be as required by the Detail Specification. 3.3 Other equipment 3.3.1 Immersion Thermometer, 0 to 200 C range. 3.3.2 Table stove, hot plate, circulating air oven, or other sui
42、table heat source, capable of attaining the specified temperatures and of maintaining temperatures within 2C of the required setting. 3.3.3 Timer. 3.3.4 Micrometer caliper. 3.3.5 Analytical balance. 3.4 Optical apparatus Optical transmittance change measurement apparatus as described in FOTP-20. 4 H
43、azards This test procedure may involve certain hazardous materials, operations, and equipment. It is the responsibility of whomever uses this procedure to establish appropriate safety practices and to determine the applicability of regulatory limitations prior to use. Note, in particular, that some
44、of the fluids that may be used (including some fluids not specified in the tables of this procedure, but that may be required by Detail Specification) 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. Prope
45、r precautions shall be observed during handling and during the balance of the test. Chronic, prolonged, or excessive exposure to solvents such as Freon TMC, 1-1-1 Trichloroethane, Methylene Chloride, Methyl Isobutyl Ketone, or others may act as a carcinogen or damage internal organs. Use such test f
46、luids 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 safety data sheets for such materials. ANSI/TIA-455-12B 5 5 Sampling and Specimens 5.1 Optical Fiber Cable Unless otherwise specified in the Detail
47、 Specification, the test sample for the Cable Test shall be a representative sample of a completed optical fiber cable. The samples shall be long enough to yield the number of specimens required. Specimen length shall be 2 meters (6.6 ft) 5% for each fluid investigated. 5.2 Connecting Device Unless
48、otherwise specified in the Detail Specification, the test sample for the Connector Test shall be a connecting device prepared as described in any one of the following categories: 5.2.1 Two optical cables terminated by mated connectors. Each cable shall be of sufficient length to perform optical tran
49、smittance measurements. 5.2.2 An unmated pair of connector plugs, or unmated plug and receptacle, shall terminate sufficient lengths of optical fiber cable to permit performance of optical transmittance measurements. 5.2.3 An unmated and unterminated connector. 5.3 Other components The test sample shall be a component prepared as required by the Detail Specification. 6 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
