15、ension wire shall meetthe requirements of this specification. The polymer coatingshall be formulated and produced properly to conform to therequirements of this specification.6. Manufacture6.1 Class 1 polymer-coated wire shall have the coatingextruded onto wire that conforms to the requirements as g

16、ivenin Table 1.6.2 Class 2a polymer-coated wire shall have the coatingextruded and adhered to wire that conforms to the requirementsas given in Table 1.6.3 Class 2b polymer-coated wire shall have the coatingfused and adhered to wire that conforms to the requirements asgiven in Table 1.7. Size of Wir

17、e7.1 The permissible variation from the specified diameter ofthe core wire, 0.177 in. (4.50 mm) 7 gage or 0.148 in. (3.76mm) 9 gage, shall be 60.005 in. (0.13 mm).8. Breaking Strength8.1 Tension wire shall meet the minimum breaking strengthindicated in Table 2 when tested in accordance with TestMeth

18、ods and Definitions A 370.8.2 Specimens to establish conformance with this require-ment shall comprise individual pieces from a coil of the tensionwire. The specimens shall be of sufficient length so as to begripped firmly in the testing machine. The polymer coatingmay be removed from the sample by

19、chemical or mechanicalmeans before testing.9. Weight of Metallic Coatings9.1 The weight of the metallic coating shall conform toTable 1.9.2 The weight of the coating shall be determined on anindividual piece of wire over 12 in. (305 mm).9.3 The weight of the zinc or zinc-5 % aluminum mis-chmetal all

20、oy coating shall be determined by the methodcontained in Test Method A 90/A 90M after stripping thepolymer coating as outlined in Section 10.9.4 The weight of the aluminum coating shall be determinedby the method contained in Test Method A 428/A 428M afterstripping the polymer coating as outlined in

21、 Section 10.10. Thickness of PVC Coating10.1 The thickness of the coating shall be in accordancewith Table 3.10.2 The thickness of the coating shall be determined on anindividual piece of wire. This specimen may be any length ofwire over 12 in. (305 mm).10.3 For Class 1 and Class 2a material, strip

22、the coatingmechanically from the wire and measure the minimum andmaximum thickness of the coating with a suitable micrometer.10.4 For Class 2b material, strip the coating by chemicalmeans and determine the diameter of the bare wire. Scrape thecoating from one side of the wire and measure the reduced

23、diameter with a micrometer. The thickness of the coating at thispoint is the difference between the measurement thus obtainedand the measured diameter of the bare wire. In a similarmanner, determine the thickness of the coating at right anglesto the first determination.10.5 Take care not to remove a

24、ny of the metallic surfacewhen removing polymer coating by scraping.11. Properties of Polymer-Coated Tension Wire11.1 The polymer-coated tension wire shall have a demon-strated ability to conform to the following requirements:11.2 Adhesion Tests:11.2.1 Class 2a must conform to the requirements of 11

25、.2.2.Class 2b must conform to the requirements of 11.2.3.11.2.2 Three specimens from each lot shall be tested.Measure a distance of34 in. (19 mm) from the end of thespecimen. With a regular hand grip wire stripper, exert maxi-mum hand pull parallel to the axis of the wire. Attempt toremove the measu

26、red portion of the polymer sleeve from thecore wire. The lot shall be acceptable if the polymer sleeve isnot capable of being removed from the core wire on all threesamples.11.2.3 Three specimens from each lot shall be tested. Maketwo cuts parallel to the axis of the wire through the coating,approxi

27、mately116 in. (1.6 mm) apart, at least12 in. (12.7 mm)long. With a knife, peel back a section of the coating between18 and14 in. (3.2 and 6.4 mm) long to produce a tab. Attemptto remove the116-in. (1.6-mm) strip of coating by pulling thetab. The lot shall be acceptable if the coating breaks rather t

28、hanseparates from the core wire on all three specimens.11.3 Accelerated AgingThe polymer-coated wire shallwithstand exposure for 1000 h without failure at a black paneltemperature of 145F (63C) when tested in accordance withPractice D 1499. The appropriate apparatus described in Prac-tices G 152 or

29、G 153 shall be used for the test. The productshall be construed to have failed the test if one of the followingoccurs:TABLE 1 Breaking Strength of Metallic-Coated Core WireSpecified Diameter of Core Wire,in.
