摘要：This specification covers the requirements for fibrous glass blanket thermal and acoustical insulation for use in aircraft applications up to a specified temperature. The fibrous glass blanket insulation are classified into types according to temperature limits, into classes based on acoustical properties, grades according to nominal density and into groups based on thickness. The insulation can either be water repellent or non-water repellent. The materials should conform to the required values of density, handleability, burning characteristics, water repellency and wicking (for water-repellent insulation only), odor emission, service temperature, apparent thermal conductivity, specific transverse airflow resistance, and breaking strength.
摘要：This specification covers a corrosion and heat-resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging and flash welded rings. These products have been used typically for parts requiring high strength at temperatures in the range 800 to 1100 °F (427 to 593 °C), particularly those which are formed or welded, but usage is not limited to such applications.
