Current edition approved Sept. 27, 1973. Published No vember 1973. Originally published as D 1056 - 49 T. Last previous edition D 1056 - 68.Measuring Compression Set of Solid Elastomers. Most compression set testing follows ASTM D395, Test Method B. Solid elastomer specimens 0.25″ thick x 0.52″ diameter are compressed to 0.177″ thick using a device as diagrammed, for 22 to 70 hour periods at elevated temperature in an air circulating oven. Compression set represents the percent of deflection that did not return.Materials Testing System Depending on maximum expected forces, ASTM D575 is performed on a single column or dual column universal testing system such as Instron's 3400 and 6800 Series systems. This system setup requires a matching load cell and upper and lower platens with diameters larger than the diameter of the specimen.
