ASTM B263-14 (R2020) pdf free.Standard Test Method for Determination of Cross-Sectional Area of Stranded Conductors.
1.1 This test method covers the procedure for determining the cross-sectional area of stranded conductors by the mass method.
1.2 The values stated in inch-pound or SI units are to be regarded separately as the standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
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; health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standard ization 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.
2.1 The following documents form a part of this test method to the extent referenced herein.
2.2 ASTM Standards:B830 Specification for Uniform Test Methods and Frequency.
3.1 lot, n- -a lot is any amount of stranded conductor of one type and size presented for acceptance at one time.
3.2 sample, n- a sample is a quantity of production units (reels, spools, coils, and so forth) selected at random from the lot for the purpose of determining conformance of the lot to the requirements of this test method.
3.3 specimen, n- a specimen is a length of stranded conductor removed for test purposes from any individual production unit of the sample.
4.1 Balance, for measurement of mass, accurate to 0.1 %.
4.2 Steel Scale, for measurement of length, with smallest divisions not greater than V/32 in. [1 mm].
4.3 Jig, or equivalent equipment, for cutting the conductor to length and at right angles to its axis.
5.1 Samples shall be taken from the outer end of reel or spool lengths, or from either end of coiled lengths.
5.2 Unless otherwise specified by the purchaser at the time of placing the order, a sample shall consist of the number of production units (reels or coils) shown in Table 1 or in accordance with Specification B830.ASTM B263 pdf download.
