The products may be specified with various factory-applied facings, or may be ordered unfaced. Add to Alert PDF. We have no amendments or corrections for this standard.
Each of these types is further classified by compressive resistance. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. Subscription pricing is determined by: 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. 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.
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.
Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. This axtm does not purport to address all of the safety concerns, if any, associated with its use.
These insulations are flexible and are normally supplied as batts or rolled blankets.
This standard contains five 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 fibers manufactured from rock, slag, or glass, with or without binders.

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 sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content. The standard contains five types classified primarily by maximum use temperature.

The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. Need more than one copy? Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value.
Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. This abstract is a brief summary of the referenced standard. Historical Version s – view previous versions of standard. If the document is revised or amended, you will be notified by email. 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.
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.
These products are supplied in rigid and semi-rigid board form. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes. The fibers may be organic or inorganic and they are normally but not always held together by a binder. Your Alert Profile lists the documents that will be monitored. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space.

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.
