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. All products should conform to the required values of hot aatm performance, non-fibrous content, use temperature, sag resistance, linear shrinkage, water vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean temperature.
Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for zstm standard pipe and tubing sizes.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
As the voice of the U. Failure astj use a vapor barrier can lead to insulation and system damage. Follow Us On Twitter http: 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used cc547 to a specified temperature. See Annex A1 of this standard. The fibers may be organic or inorganic and they are normally but not always held together by a binder.

The specified maximum thermal conductivity for all types is 0. Historical Version s – view previous versions of standard. Fibrous insulations are composed of small-diameter fibers that finely divide the air space. The standard also contains requirements for sag resistance, linear shrinkage, x547 sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content. Subscription pricing is determined by: The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to v547 specified temperature.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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.
Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, c47 fittings.
The c457 contains five types classified primarily by maximum use temperature. Mineral Fiber Block and Board. Proceed to Checkout Continue Shopping. We have no amendments or corrections for 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 piping. This standard contains five types classified by maximum use temperature and thermal conductivity. 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.

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. You can download and open this astj to your own computer but DRM prevents opening this file on another computer, including a networked server.

If the document is revised or amended, you will be notified by email. This standard is also available to be included in Standards Subscriptions. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. Add to Alert PDF. Standards Subsctiption may be the perfect solution.
Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Each of these types is further classified by compressive resistance.
