ASTM D1447 : 89(1994)e1

Standard Test Method for Length and Length Uniformity of Cotton Fibers by Fibrograph Measurement

Standard Details

1.1 This test method covers the measurement of the length and length uniformity of cotton fibers by use of the Fibrograph. The test method is applicable to fibers taken from raw or partially processed cotton or some types of cotton waste, but not to fibers from blends of cotton with other fibers or to fibers recovered from cotton yarns or fabrics.

1.2 This test method covers procedures for all models of the Digital Fibrograph, hereafter referred to as Fibrograph.

Note 1--Instructions for the use of Manual and Servo Fibrograph Models were included in the text of Test Method D1447 in 1971 and previous editions.

Note 2--For other methods covering the measurement of the length of cotton fibers refer to Test Method D1440.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
