If the document is revised or amended, you will be notified by email. Fiberglass and mineral wool products fall in this category.
Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. Follow Us On Twitter http: This standard does not purport to address all of the safety concerns, if any, associated with atm use. The specified maximum thermal conductivity for all types is 0.
Standards Subsctiption may be the perfect solution. Fibrous insulations are composed of small-diameter fibers that finely divide the air space.
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. 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. See Annex A1 of this standard. Historical Version s – view previous versions of standard.
Work Item s – proposed revisions of this standard. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field.
These insulations are flexible and are normally supplied as batts or rolled blankets. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.
This standard contains five types classified by maximum use temperature and thermal conductivity.
ASTM C – Standard Specification for Mineral Fiber Pipe Insulation
The values given in parentheses are mathematical conversions to SI units that astj provided for information only and are not considered standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Each of these types is further classified by compressive resistance.
This standard is not included in any packages. Category 1 materials have asrm 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. Failure to use a vapor barrier can lead to insulation and system damage. 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.
Your Alert Profile lists the documents that will be monitored. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature.

Already Subscribed to this document. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations. 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. 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. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products.
Mineral fiber pipe ashm systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings. Subscription pricing is determined by: The products may be specified with various factory-applied facings, or may be ordered unfaced. Mineral Fiber Block and Board. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
