ASTM C800-14 pdf download.Standard Specification for Fibrous Glass Blanket Insulation (Aircraft Type).
5. Ordering Information
5.1 The type, class, grade, and group suited to the conditions of intended service shall be specified by the purchaser after consultation with the supplier. Type refers to service temperature, class refers to thermal/acoustical properties, grade refers to nominal density and group refers to thickness of insulation.
5.2 It shall also be specified whether the insulation is to be water repellent or non-water repellent.
6. Materials and Manufacture
6.1 Composition:
6.1.1 Fiber shall be glass processed from a molten state into fibrous form.
6.1.2 Binder shall be of a type and quantity to provide the properties and performance listed in this specification. Addi- tives can be included to provide a degree of water repellency.
6.1.3 This product is typically supplied unfaced. 6.1.4 The basic product can also be obtained in uncured form for molding into special shapes other than blanket. However, not all requirements in this specification apply. The purchaser shall consult the supplier and agree on the portions of this specification and conditions that are applicable. 6.2 For sizes and densities other than those listed, the purchaser shall consult the material supplier.
7. Physical Requirements
7.1 The insulation shall conform to the requirements de- scribed in 7.2 – 7.11 and Tables 1-5.
7.2 Density—The insulation shall conform to the require- ments shown in Table 1. The insulation shall have a maximum density tolerance when tested in accordance with 11.6 of + 15%, with no minimum limit.
7.3 Handleability—Each piece of insulation shall be suffi- ciently coherent to permit transportation and installation as a unit
. 7.4 Burning Characteristics—The insulation shall conform to the requirements in FAR 25.853, Appendix F, Part I and the encapsulated insulation blanket shall conform to the require- ments in FAR 25.856(a) in accordance with 11.1. If required, unfaced blankets are tested with alternative methods or require- ments recognized by airframe manufacturers to demonstrate and maintain product consistency.
7.5 Wicking (water-repellent insulation only)—The insula- tion shall conform to the requirements in Table 2, when test in accordance with 11.2.
7.6 Odor Emission—A detectable odor of objectionable nature recorded by more than two of the five panel members shall constitute failure of the material, when tested in accor- dance with 11.3.
7.7 Service Temperature—The insulation shall conform to the requirements in Table 1, when tested in accordance with 11.7.
7.7.1 Insulation shall be serviceable up to the maximum temperature limitations as long as limited mechanical proper- ties are required. At maximum or near-maximum service temperatures, some deterioration of the binder is possible over extended periods of time.
7.8 Apparent Thermal Conductivity—Values shall not ex- ceed those in Table 3, when tested in accordance with 11.9.
7.9 Specific Transverse Airflow Resistance—The insulation shall conform to the requirements in Table 4, when tested in accordance with 11.4.
7.10 Breaking Strength—The insulation shall conform to the requirements in Table 5, when tested in accordance with 11.5.
7.11 Water Repellency (water-repellent insulation only)— The insulation shall conform to the requirements of Table 2, when tested in accordance with 11.8. 7.12 The insulation shall be rated 0 (no visible corrosion) when tested per the requirements of Test Method F1110 on non-clad aluminum (2024T3).ASTM C800 pdf download.
