Breaking Strength8.1 Tension wire shall meet the minimum breaking strengthindicated in Table 2 when tested in accordance with Te
18、stMethods 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 samp
19、le by 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-chmet
20、al alloy 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 after strippingthe 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 t
22、he 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 reducedd
23、iameter 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 an
24、y 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.

With a regular hand grip wire stripper, exert maxi-mum hand pull parallel to the axis of the wire. Attempt toremove the measur
26、ed 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,approxim
27、ately116-in. (1.6-mm) apart, at least12 in. (12.7 mm)long. With a knife, peel back a section of the coating between18and14 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 tha
28、nseparates 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. Type D, E, or F apparatus described inPractice G 23 or Type B
29、H apparatus described in Practice G 26shall be used for the test. The product shall be construed tohave failed the test if one of the following occurs:11.3.1 Shrinkage of the polymer coating shall be no greaterthan116 in./ft (1.6 mm/305 mm) of wire, or11.3.2 There shall be no significant change in c
