iSmithers Rapra Publishing has release Roger Brown’s “50 Years of Polymer Testing.” Since the beginning of the rubber and plastics industries, an essential requirement has been that the materials and the products are tested for quality control. Testing establishes their fitness for purpose and provides design data. Brown’s book gives a unique personal account–Brown has headed up Rapra’s testing laboratory–of the developments in the technology of physical testing of polymers and of the changes in the working environment in which testing was conducted over the last fifty years.
