1. Scope
1.1 This specification covers figure-9 deep-section grooved and figure-8 copper trolley wire for use in industrial haulage (Explanatory Note 1). 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Ordering Information
3.1 Orders for material under this specification shall include the following information: 3.1.1 Quantity of each size and section, 3.1.2 Wire size: circular-mil area (Section 6, Fig. 1 or Fig. 2), 3.1.3 Shape of section (Section 1), 3.1.4 Type of copper, if special (Section 4), 3.1.5 Package size (see 14.3), 3.1.6 Lagging, if required (see 14.1), 3.1.7 Relation between vertical axis of grooved wire and axis of reel (see 14.1), 3.1.8 Size of arbor hole if other than for a 2 1 ⁄ 2 -in. (64-mm) shaft (see 14.2), 3.1.9 Special package marking, if required (see 14.4), and 3.1.10 Place of inspection (Section 12).
4. Materials and Manufacturer
4.1 The material shall be copper of such quality and purity that the finished product shall have the properties and charac- teristics prescribed in this specification. N OTE 1—Specification B49 defines the materials suitable for use. 4.2 Copper bars of special qualities, forms, or types, as may be agreed upon between the manufacturer and the purchaser, and that will conform to the requirements prescribed in this specification may also be used.
5. Tensile Properties
5.1 Figure-8 wire shall conform to the requirements as to tensile properties specified in Table 1. 5.2 Figure-9 deep-section grooved wire shall conform to the requirements as to tensile properties specified in Table 2. 5.3 Tests on a specimen of wire containing a joint shall show at least 95 % of the tensile strength specified in Table 1 or Table 2, as may be applicable. Elongation tests shall not be made on specimens containing joints. 5.4 Tension tests shall be made on representative samples. The elongation shall be determined as the permanent increase in length, due to the breaking of the wire in tension, measured between gage marks placed originally 10 in. apart upon the test specimen (Explanatory Note 1). The fracture shall be between the gage marks and not closer than 1 in. (25 mm) to either gage mark. 5.5 The twist test shall be omitted.
6. Sections
6.1 Standard sections of figure-8 trolley wire shall be those shown in Fig. 1. 6.2 Standard sections of figure-9 deep-section grooved trol- ley wire shall be those shown in Fig. 2.
7. Dimensions and Permissible Variations
7.1 The size shall be expressed as the nominal area of cross section in circular mils. 7.2 The standard sizes of figure-8 trolley wire shall be as specified in Fig. 1. 7.3 The standard sizes of figure-9 deep-section grooved trolley wire shall be as specified in Fig. 2. 7.4 The weight in pounds per mile in figure-8 and figure-9 trolley wire calculated from the weight of a specimen not less than 18 in. (457 mm) in length shall not vary more than 65 % from that specified in Fig. 1 and Fig. 2, respectively. 7.5 Conformance of the trolley wire to the specified dimen- sions shall be determined by taking the measurements shown in Fig. 1 and Fig. 2 under heading, “Dimensions for Inspection, in.” The shape of the groove for figure-9 trolley wire shall be checked with the“ go” and“ no-go” slip gages described in Fig. 3. The gages shall be applied to the ends of the samples taken from each reel. Samples shall be clean and ends free from burrs. The groove shall be considered as conforming to this specification ifthe “go” gage can be pushed on the straightened wire by hand and the “no-go” gage cannot be pushed on the wire.
