This standard specifies the method for determining fiber length of papermaking raw materials using the raster method. It is applicable to various papermaking raw materials. The fiber image is magnified and the length is automatically measured by a grating displacement sensor. The standard calculates mean length, length-weighted mean length, mass-weighted mean length, and fines content. It details apparatus, reagents, sampling, sample preparation, test procedure, and calculation methods, requiring a relative error of no more than ±2% between two parallel tests.
