Standard Test Methods for Measuring Diameter or Thickness of Wire and Ribbon for Electronic Devices and Lamps

Standard Test Methods for Measuring Diameter or Thickness of Wire and Ribbon for Electronic Devices and Lamps

ABSTRACT
These test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) used in electronic devices and lamps. Anvils shall be used in determining the thickness. The flatness and parallelism of the wire shall be checked using a monochromatic light source, a small optical parallel, and a cylindrical master standard wire gage.
SIGNIFICANCE AND USE
The methods contained in this standard are intended primarily for referee use, for laboratory measuring, and for certifying size of standard samples used for checking other measuring equipment that may be agreed upon between the supplier and the purchaser.
SCOPE
1.1 These test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) 0.060 in. (1.52 mm) maximum used in electronic devices and lamps.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers round wires made from UNS N02211, UNS N10001, or N03300 nickel alloy or molybdenum, with diameters within a specified range, for winding electron tube grid laterals. The wires are classified into five classes based on tensile properties. All wires should conform to the required values of tensile strength, yield strength, working range, and elongation properties. The surface of each bare wire should be bright and free from cracks, slivers, fissures, lubricants, or other detrimental defects, while all platings should be free from bubbles, flakes, blisters, porosity, and plating salts. Wires should be spooled in one continuous length and in such a manner that it can be unwound under reasonable tension without binding or becoming distorted.
SCOPE

The aluminum-clad steel core shall undergo elongation test, tension test, and torsion test. The elongation test shall be determined by an extensometer equipped with a vernier or other instrument reading. In the torsion test, a small tensile load shall be applied to the specimen during testing. The specimen shall be twisted by rotating one of the vises in the same direction until fracture occurs.
SCOPE
1.1 This specification covers round, aluminum-clad steel core wire with two designations of tensile strengths, AW2 (Normal Strength) and AW3 (High Strength).  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.2.1 For conductor sizes designated by AWG, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Copper-Clad Steel Electrical Conductor for CATV Drop Wire

ABSTRACT
This specification covers hard-drawn round copper-clad steel electrical conductor for CATV drop wire (coaxial cable center conductor). The wire shall be composed of a steel core with a substantially uniform and continuous copper cladding thoroughly bonded to it throughout. The size shall be expressed as the diameter of the wire. The steel wire shall conform to the prescribed tensile strength, elongation, and breaking strength. Requirements for (1) tension and torsion tests, (2) method of determining the electrical resistance, (3) cladding uniformity in terms of thickness, and (4) joint construction are detailed. The prescribed density of the wire to be taken for calculating mass/unit length, cross section, and so forth is given.
SCOPE
1.1 This specification covers 21 % conductivity hard-drawn round copper-clad steel wire for coaxial cable center conductors (Note 1).  
Note 1: Wire ordered to this specification is not intended for redrawing since it is furnished in the hard-drawn temper. If wire is desired for the purpose, the manufacturer should be consulted.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
