This test method establishes the standard procedures and calculations used (including precision and biases) for determining, to an accuracy of 1.0 %, the density of fine wires and ribbon wires that are used in electronic devices. This test method requires the use of the following apparatus: chemical balance, micrometer, standard volume cylinder, thermometer, vacuum pump and desiccator, and hook and cradle suspended by a fine wire.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This test method covers the determination of, to an accuracy of 1.0 %, the density of fine wires ranging from 0.25 to 0.02 mm in diameter, or ribbons of similar thicknesses, for electronic devices.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. Specific hazard statements are given in Section 4.
