Written in easy-to-read and -use format, this book updates and revises its bestselling predecessor and remains the most complete, comprehensive resource on plastics testing. Since publication of the third edition, very little, has changed regarding plastics testing methods, whereas there have been changes in the manner in which the data is collected, displayed, and analyzed. Personal computers and digital instruments have made data acquisition and analysis simpler and faster and substantial reduction in equipment and testing costs have lead laboratories to routinely use a greater array of testing and identification methods. Also, due to the increase in litigations related to product liability, there has been renewed interest in learning more about failure analysis and the test methods employed to determine the root cause of part failure. Therefore, this new 4th edition enhances coverage of failure analysis and adds an emphasis on product liability concerns. Including updated chapters on identification analysis, failure analysis, and case studies, the book covers all aspects of plastics testing, failure analysis, and quality assurance. The book concludes with a substantial appendix with useful data, charts and tables for ready reference. A companion, supplementary website has a video tour of a plastics testing plant to illustrate what really goes on in the practical world of plastics testing.
