TAPPI T401 OM 2015

Official TAPPI/ANSI test method for qualitative identification and quantitative analysis of fibers in paper and paperboard.

TAPPI/ANSI T 401 om-15 provides a laboratory procedure for identifying fiber types in paper and paperboard and estimating their proportions by weight. The standard covers equipment, reagents, sampling, specimen disintegration, slide preparation, staining techniques, microscopic identification, quantitative fiber counting, weight factors, reporting requirements, precision, and morphological guidance for wood, rag, nonwood, synthetic, and other fibers. It is intended for experienced pulp and paper analysts, quality laboratories, manufacturers, and technical professionals evaluating fiber composition and compliance with material specifications.

Application Scope: Fiber analysis, paper and paperboard quality control, pulp identification, furnish verification, microscopy laboratories, and research involving wood and nonwood fibers.
