ASTM C411 Standard Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationASTM C411 高温隔热材料受热面性能的标准试验方法Performance in service is the final measure of value for a thermal insulation, but simulative service tests give useful indications. One type involves application for a specified time to a surface heated at a temperature approximately that of intended service, and noting during the test and afterward, changes in the material and its properties. Measurement of these changes are used for predicting what occurs in service as a result of exposure to temperatures corresponding to those of the tests.1. ASTM C411标准适用范围1.1 This test method covers the determination of the performance of commercial sizes of both block and pipe forms of thermal insulating materials when exposed to simulated hot-surface application conditions. The term “hot-surface performance” has reference to a simulated use-temperature test in which the heated testing surface is in a horizonta
