Foreword
This revised standard adopts IWTO-12-03 "Cerro (Sirolan) laser scanning fiber diameter analyzer to determine the average fiber diameter and fiber
The method of "fiber diameter distribution (in English).
The standard measurement of the average fiber diameter and fiber straight according IWTO-12-03 "Cerro (Sirolan) laser scanning fiber diameter analyzer
The method of size distribution "redrafted. For ease of comparison, in Appendix A lists the control of the standard terms and the standard terms of a IWTO
Lanbiao.
This standard when using IWTO standard has been modified. Modify technical differences between a single vertical line identifies the article to which they are involved
Section of the page margin. In Appendix B gives a list of the technical differences and the reasons for the reference.
For ease of use, this standard also made the following editorial changes.
a) "The Program" be replaced by "this standard";
b) use a decimal point instead of a decimal comma ",". ",";
c) Remove the IWTO standard brief history and introduction;
d) name of the standard was changed to "the average diameter of the wool fiber and its distribution Test methods for laser scanner method."

Principle 3
An aqueous solution of test specimens cut from the test sample into isopropanol (8 per cent of the water volume) or as an aqueous solution into the detergent
For the diluted suspension to be dispersed, so that the test specimen is mounted by the measuring unit of the laser beam. Laser beam diameter of about 500μm, when each sample
Test specimen by the laser beam, the intensity of the laser beam is weakened which monitor calibration sensor and by transforming into a test station in microns
Fiber diameter, the computer samples the measured values \u200b\u200band statistics collection, and give the sample mean and standard deviation of the diameter of the data.
