The standard contains seven types classified by maximum use temperature and thermal conductivity. Mineral Fiber Fiberglass and Mineral Wool. Mineral fiber insulations are defined by ASTM as insulations composed principally of astn manufactured from rock, slag, or glass, with or without binders.
Refer to Practice C to aid material selection.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the asrm of regulatory limitations prior to use. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value.
See Annex A1 of this standard. 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. This standard does not purport to address all of the safety concerns, if any, associated with its use.
Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products.
Fiberglass and mineral wool products fall in this category. This abstract is a brief summary of the referenced standard. Asstm pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. There is some confusion concerning the nomenclature used for these materials. Further, there is an optional aatm in ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless steel.
Exploring Insulation Materials
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Failure to use a vapor barrier can lead to insulation and system damage. The standard also contains requirements awtm linear shrinkage, water-vapor sorption, surface-burning characteristics, odor emission, corrosiveness to steel, rigidity, and shot non-fibrous content.
The specified maximum thermal conductivity for all types is 0. 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. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field.
ASTM C – 17 Standard Specification for Mineral Fiber Pipe Insulation
These products are supplied in rigid and semi-rigid board form. Each of these types is further classified by compressive resistance. The products may be specified with various factory-applied facings, or may be ordered unfaced.
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 flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content.
This standard contains five types classified by maximum use temperature and thermal conductivity. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content. 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.
Historical Version s – view previous versions of standard. Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Mineral Fiber Block and Board.
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 insulations are flexible and are normally supplied as batts or rolled blankets. The fibers may be organic or inorganic and they are normally but not always held together by a binder. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered wstm.
This specification aatm mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
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.
Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. The standard contains five types classified primarily by maximum use temperature.
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. The standard further classifies products by grade. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations. Follow Us On Twitter http:
