1.1 This test method involves the measurement and analysis of two-dimensional projections of flax fibers using image analysis software in the longitudinal plane to determine the average and distribution of fiber widths.

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.


5.1 Longitudinal preparation is much quicker and less damaging than cross-sectional analysis and allows the fibers to be evaluated in their natural state.

5.2 This test method provides measurement of a flax fiber specimen that uses less specimen preparation, produces consistent results, and minimal specimen modification. It has been shown that the median values of width correlate very well with the Optical Fiber Diameter Analyzer (OFDA), an apparatus developed for measuring the value and distribution of wool fiber diameters.
