2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the composition, thermal performance, sound absorption per
3、formance, and physical properties ofhigh-temperature fiber thermal insulation for use at temperatures from ambient to 3000F (1649C).1.2 The dry, loose high-temperature fibers shall be pneumatically conveyed to a nozzlechamber where they are mixed with awater-based chemical binder.binder and then con
4、veyed to a nozzle.1.3 The pneumatically applied, high-temperature fiber insulation is intended for use in industrial applications on flat, or nearlyflat, surfaces. It is not intended for use on pipes.1.4 This specification addresses the use performance of this material in both thermal and acoustical
5、 applications.1.5 This specification does not address the requirements for fire-resistive insulation, but it does not preclude this materials usein that capacity.1.6 This is a material specification only and is not intended to cover methods of application that are provided by themanufacturer.1.7 The
