Abstract

This specification covers mineral fiber blanket insulation and blanket-type pipe insulation (metal-mesh covered) and (industrial type). The mineral fiber blanket shall be composed of rock, slag, or glass processed from the molten state into fibrous form, covered with or without metal mesh, metal mesh secured with metallic supporting wire, covered with or without facings for industrial type blanket-type pipe, and bonded with or without an organic binder. Types of facings for one or both sides of blanket units shall be specified. When both sides are to be faced, units are permitted to have the same or different types on the two sides. Each piece of industrial type or metal-mesh covered insulation shall be coherent to permit handling/transportation and installation as a unit. A detectable odor emission of objectionable nature recorded by more than two of the five panel members shall constitute rejection of the material. When tested and evaluated, the corrosion resulting from the unfaced insulation blanket in contact with metal plates shall be judged to be no greater than comparative plates in contact with sterile cotton. Alternative test for corrosiveness to steel is with a mass loss corrosion rate to the steel test sample exposed to the unfaced insulation extract not to exceed that of the 5 ppm chloride solution. The averaged maximum shot content of mineral fiber rock or slag type products shall not exceed 25 % by weight. When tested, the blanket insulation shall not warp, flame, or glow during hot surface exposure. When tested, the blanket mid-point temperature shall not at any time exceed the hot surface temperature by more than 100°F (55.5°C). When tested for non-combustibility, the blanket insulation shall not exceed the recorded temperature rise more than 54°F (30°C) with no flaming and weight loss exceeding 5 %.

Scope

1.1 This specification covers the composition, dimensions, and physical properties of mineral fiber (rock, slag, or glass) metal mesh covered and industrial type blanket and blanket-type pipe insulation (typically on 24 in. (610 mm) diameters or larger)). Its use is for cooled surfaces at temperatures operating below ambient to 0°F (−18°C) and on heated surfaces on expansion joints to large diameter vessels and tanks operating at temperatures up to 1200°F (649°C). Specific applications outside the actual use temperatures shall be agreed upon between the manufacturer and purchaser.

1.2 For satisfactory performance, properly installed protective vapor retarders or barriers shall be used on below ambient temperature applications to reduce movement of moisture/water vapor through or around the insulation towards the colder surface. Failure to use a vapor retarder can lead to insulation and system damage. Refer to Practice C921 to aid material selection. Although vapor retarder properties are not part of this specification, properties required in Specification C1136 are pertinent to applications or performance.

1.3 The orientation of the fibers within the blanket is primarily parallel to the heated surface. This specification does not cover fabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide fiber orientation that is perpendicular to the heated surface.

1.4 This standard does not purport to provide the performance requirements of hourly-rated fire systems. Consult the manufacturer for the appropriate system.

1.5 See Supplementary Requirements for modifications to sections in this standard only when specified by purchaser in the contract or order from the U.S. Military specifications utilized by the U.S. Department of Defense, Department of the Navy, and the Naval Systems Command.

1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
