ASTM C553 Standard Specification for Mineral Fiber Blanket Thermal Insulation for Commercial and Industrial Applications
ASTM C553 商用和工业用矿物纤维毡隔热的标准规范
This specification covers the classification, composition, physical properties, and dimensions of mineral fiber (rock, slag, or glass) blanket intended for use as thermal insulation on surfaces at certain temperatures. The orientation of the fibers within the blanket is primarily parallel to the principal surface (face). The mineral fiber blanket insulation shall be classified into seven types: Types I, II, III, IV, V, VI, and VII. The classification is based upon the insulations' maximum use temperature and apparent thermal conductivity. Mineral fiber blanket insulation shall be composed of rock, slag, or glass processed from the molten state into fibrous form bonded with an organic or inorganic binder, or both. Asbestos shall not be used as an ingredient or component part of the product. Different test methods shall be performed on the insulation to determine the following properties: odor emission, corrosiveness to steel, non-fibrous content, maximum use temperature, maximum exothermic temperature rise, apparent thermal conductivity, water vapor sorption, flexibility, rigidity, and surface burning characteristics.
