This abstract is a brief summary of the referenced standard. See Aatm A1 of this standard. This standard contains five types classified by maximum use temperature astm c547 thermal conductivity. The standard astm c547 contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content.
Mineral Fiber Fiberglass and Mineral Wool. The mineral fiber insulation should be manufactured from molten mineral substances such as rock, slag, or glass and processed into fibrous form using a binder, and adhesives when astm c547. Failure to use a vapor barrier can lead to insulation and system damage. This specification astm c547 mineral fiber pipe insulation that are ashm into hollow cylinders for standard pipe and tubing sizes.
Historical Version s – view previous versions of standard. Category 1 materials have no requirement for c5447 resistance, while Category 2 materials require a astm c547 compressive resistance value.
Specifiers are cautioned to call out both the specific material and the ASTM type and astm c547 when specifying these products. Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes.
The standard contains five types classified primarily by maximum use temperature. Fiberglass and mineral wool products x547 in this category.
Exploring Insulation Materials
These products are intended to keep the insulation material dry for chilled water piping asrm high-humidity locations. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space.
The astm c547 given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Link astm c547 Active This link will always route to the current Active version of the standard. ASTM does astm c547 give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Work Item s – proposed revisions of this standard. Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless steel. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. The specified maximum thermal conductivity for all types is 0. The standard further classifies products by grade.
The products may be specified with various factory-applied facings, or may be ordered unfaced. Astm c547 to Practice C to aid material selection.
Fibrous insulations are composed of small-diameter fibers that finely divide the air space. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and astm c547 shot content.
All products should conform to the required values of hot surface performance, non-fibrous content, use temperature, sag resistance, linear shrinkage, water vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean astm c547.
It is the responsibility of the user of this standard to establish astm c547 safety and health practices and determine the applicability of regulatory limitations prior to use. These products are supplied in rigid and semi-rigid board form. The standard also astm c547 requirements for linear shrinkage, water-vapor sorption, surface-burning characteristics, odor emission, corrosiveness to steel, rigidity, and shot non-fibrous content.
Mineral Fiber Block and Board. The fibers may be organic or inorganic and they are normally but not always held together by a binder. These pipe insulation products may be specified with various astm c547 facings, or they may be jacketed in the field. Mineral Fiber Fiberglass and Mineral Wool Mineral astm c547 insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.
It is informational only and not an official part of the standard; the full text of the standard itself astm c547 be referred to for its use and application.
The materials are classified into five types according to the processing method used to form the material and the operating temperatures and into two grades astm c547 to heating requirements. These insulations are flexible and are normally supplied as batts or rolled blankets.

ASTM C – 17 Standard Specification for Mineral Fiber Pipe Insulation
Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to astm c547 used in contact with austenitic stainless steel piping. Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, astm c547, and fittings. This standard does not purport to address all of the safety concerns, if any, associated with its use. There is some confusion concerning the nomenclature used for these materials.
