Physical Testing of Paper

Physical Testing of Paper reflects on decades of experience of the author as a research scientist and lab manager providing industry clients, manufacturers, product developers, marketing and distribution organizations with data to answer queries regarding product quality concerns, variability, runnability, convertibility, printability. The basic principles underlying the various testing methods are used to illustrate how their interrelationships lead to validated findings solving problems. The book covers the basic accepted standard industry mechanical tests supplemented by ultrasonic methods applied to examples of commercial and laboratory handsheet sample sets presenting the testing technique, data and analysis. Focus is on the tests that are most frequently required such as tensile and compression strengths, stiffness for papers and corrugated board, relevant water absorption characteristics. It is aimed for the interested paper industry technologist or researcher at the introductory level who wishes to establish an understanding of what the physical testing results mean, how to avoid common pitfalls and most importantly, how to interpret the results from a paper physics point of view.
