Work Item s – proposed revisions of this standard. The specified maximum thermal conductivity for all types is 0.

This specification covers mineral fiber pipe insulation that are formed 5c47 hollow cylinders for standard pipe and tubing sizes. Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Mineral Fiber Fiberglass and Mineral Wool.

Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value.

The fibers may be organic or inorganic and they are normally but not always held together by a binder. 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 also contains requirements for linear shrinkage, water-vapor sorption, surface-burning characteristics, odor emission, corrosiveness to steel, rigidity, and shot non-fibrous content. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Mineral Fiber Fiberglass and Mineral Wool Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.

Failure to use a vapor barrier can lead to insulation and system damage. This standard does not purport to address all of the safety concerns, if any, associated with its use. Follow Us On Twitter http: 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 temperature. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field.

Exploring Insulation Materials

The standard contains seven types classified by maximum use temperature and thermal conductivity. 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 piping. This abstract is a brief summary of the referenced standard. These insulations are flexible and are normally supplied as batts or rolled blankets. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations.

Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products.

The standard further classifies products by grade. Further, there is an axtm requirement in ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless steel. The pipe insulation may be molded or precision v-grooved wstm one or more walls split longitudinally and used up to a specified temperature. See Annex A1 of this standard. Refer to Practice C to aid material selection.

These products are supplied in rigid and semi-rigid board form.

ASTM C – 12 Standard Specification for Mineral Fiber Pipe Insulation

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 preferred. Asttm of these types is further classified by compressive resistance. This standard contains five types classified by maximum use temperature and thermal conductivity. The standard also contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content.

Mineral Fiber Block and Board. Fiberglass and mineral wool products fall in this category. It is the responsibility asstm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Mineral fiber insulations are defined f547 ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The standard contains five types classified astn by maximum use temperature. The products may be specified with various factory-applied facings, or may be ordered unfaced. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.

C57 is some confusion concerning the nomenclature used for these materials.

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 according to heating requirements.
