Sinopsis

An essential tool in industries utilising paper. This book compiles years of testing techniques used at the National Institute of Standards and Technology (NIST) as well as in broader scientific communities. This book provides clear, step-by-step instructions for testing both the physical and chemical qualities of paper. The author emphasises that environmental conditions, such as temperature and humidity, influence the physical qualities of paper. The first section of the book highlights the types of paper, ingredients that are often added to it and the differences in testing among various categories of paper. The focus then shifts to discussing the processes involved in laboratory testing paper, including weight, thickness and strength, absorption, and transparency. The author also explores qualitative and quantitative chemical testing with respect to paper, including the determination of the amount and types of filling materials, as well as loading materials and sizing agents. The concluding section of this text details the processes for microscopic testing and gives insight into how to assess the relative proportions of fiber present in a sample of paper. With paper being such a pervasive material, this book is a key text for anyone working in the paper industry or related fields who desires a deeper understanding of its testing processes.
