ASTM D5959-12

1.1 This test method covers a procedure for measuring the weight of filaments per unit volume.

1.2 This test method is applicable only to monofilament with consistent longitudinal (level) profiles.

1.3 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.

1.4 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.

3.1 Filaments are available in a variety of cross sections and materials. A measure of bulk density permits the brushmaker to estimate the weight of filament required to prepare a given number of brushes.
