1.1 These practices cover test methods for testing alkyd resins as listed in Table 1. They are the test methods most often used to characterize alkyds. All of the analytical test methods were subjected to interlaboratory testing using oil-modified alkyds. Their adaptability to other types of alkyds has not been studied. Although each test method specifies a recommended amount of specimen for starting a separate analysis, several of the procedures can be conducted on the same starting specimen, if desired. For example, the tests for unsaponifiable matter, fatty acid content, oil identification, and phthalic acid content could all be run on a consecutive basis, if all were required.
