ASTM International - ASTM F180-94(2020)
Standard Test Method for Density of Fine Wire and Ribbon Wire for Electronic Devices
|Publication Date:||1 May 2020|
|ICS Code (Wires):||29.060.10|
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 4.
1.4 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.
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... View More
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 apparatuses: chemical balance, micrometer, standard volume cylinder, thermometer, vacuum pump and desiccator, and hook and cradle suspended by a fine wire.View Less
