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. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature.
Historical Version s – view d547 versions of standard. The values given in astmm are mathematical conversions to SI units that are provided for information only and are not considered v547. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations.
See Annex A1 of this standard. Failure to use a vapor barrier can lead to insulation and system damage. Refer to Practice C to aid material selection.
Fiberglass and mineral wool products fall in this category. Link to Active This link will always route to the current Active version of the 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. Astmm standard contains five 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.

Exploring Insulation Materials
Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space. 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.
Fibrous insulations are composed of small-diameter fibers that finely divide the air space. The mineral fiber insulation should be manufactured from molten c5547 substances c5447 as rock, slag, or glass and processed into fibrous form using a binder, and adhesives when preferred. This standard does not purport to address all of the safety concerns, if any, associated with its use. These products are supplied in rigid and semi-rigid board form. The standard contains five types classified primarily by maximum use temperature.
Mineral fiber pipe insulations systems are also available with self-drying wicking material axtm wraps continuously around pipes, valves, and fittings. Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to be used c47 contact with austenitic stainless steel.
The standard further classifies products by grade.
Mineral Fiber Fiberglass and Mineral Wool. Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products.
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 also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.
Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. These insulations are flexible and are normally supplied as batts or rolled blankets.
The standard contains seven types classified by maximum use temperature and thermal conductivity. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The fibers may be organic or inorganic and they are normally but not always held together by a binder. This abstract is a brief summary of the referenced standard. The specified maximum thermal conductivity for all types is 0. Mineral Fiber Block and Board. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field. The standard also contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content.
ASTM C – 12 Standard Specification for Mineral Fiber Pipe Insulation
The products may be specified with various factory-applied facings, or may be aatm unfaced. Each of these types is further classified by compressive resistance.
Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. Work Item s – proposed revisions of this standard.
