For determining the degree of cross-linking in vulcanizable clastomers, a new test method, in which the modulus is measured in a heated liquid medium, has shown superiority in accuracy and facility over several other presently used tests.
Coatings applied from powders are now serving many insulating and finish applications, particularly on motors and transformers, and the list of uses is expanding. To meet the needs with products which are strong in the most essential performance characteristics, polyester powders have been specially designed to meet integral insulation and protective coating requirements. They are very well suited...
Coatings applied from insulating powders are increasing in importance and reliable methods must be selected for their evaluation. There are no industry standards for measuring these integral films which are formed directly on surfaces and are bonded to them. In addition, there are no generally accepted specifications for the kinds of tests which are most significant. Areas of agreement on measurements...
The concept of functional testing of materials in combination in systems and its value beyond simple material property tests has been widely accepted by the electrical industry and the insulation materials suppliers, The accelerated interest in insulation systems and in the testing of systems is shown by the tremendous increase in published articles and magazine and technical journal coverage of all...
