This test method establishes the apparatus required, specimen preparation steps, and standard procedures and calculations involved in the measurement of the average diameter of fine wires by means of weighing a known length. This applies particularly to wires of specified sizes used in electron devices and lamps.

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. Scope

1.1 This test method covers the measurement of the average diameter of fine wire by weighing a known length; it applies particularly to sizes up to 0.13 mm used in electron devices and lamps.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
