3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 By a large number of equal width, equally spaced linear slit composed of optics. Raster engraving on glass is usually made. This standard Round grating with grating, engraved with 200 weekly slots. 3.2 Results fiber length divided by the number of total income, by L. 3.3 By the length of the calculated weight-average fiber length represented by L1. 3.4 Calculated by the mass of the weight average fiber length, represented by Lw. Note. In the past, the number average fiber length Ln represents general use, length - weight average fiber length Lw represented by and referred to as the weight average fiber length; quality Volume - weight average fiber length represented by Lww, and called the double weight average fiber length. The standard line with international standards, the average number of fibers Length represented by L, the length - weight average fiber length L1 expressed by mass - the weight average fiber length is represented by Lw. Principle 4 Using a projector or projection microscope, the fiber image is enlarged on fiber samples, presented on a projection screen. Then grating displacement sensor , A moving image along the fiber, the fiber length is automatically measured out and fed to a computer for statistical calculations. Thus, the number average fiber The length dimension, the length - the weight average fiber length, mass - the weight-average fiber length and length distribution can be calculated. ......
