Mineral Fiber Fiberglass and Mineral Wool. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. Proceed to Checkout Continue Shopping. This standard is not included in any packages. Mineral Fiber Fiberglass and Mineral Wool Mineral fiber insulations are defined by ASTM aetm insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.
These insulations are flexible and are cc547 supplied as batts or rolled blankets. The standard also contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content. The fibers may be organic or inorganic and they are normally but not always held together by a binder.
Typical inorganic fibers c54 glass, rock wool, slag wool, and alumina silica. Fiberglass and mineral c5547 products fall in this category. 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. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations.
Please first log in with a verified email asym subscribing to alerts. There is some confusion concerning the nomenclature used for these materials. The pipe insulation may be molded or precision v-grooved with one or more asm split longitudinally and used up to a specified temperature. The standard contains five types classified primarily by maximum use temperature.
This abstract is a brief summary of the referenced standard. Add to Alert PDF. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
See Annex A1 of this standard.
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. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.

The standard further classifies products by grade. Refer to Practice C to aid material selection. These products are supplied in rigid and semi-rigid board form.
These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field.
Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. 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.
Standards Subsctiption may be the perfect solution. Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes.
Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Mineral Fiber Block and Board. 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.
Failure to use a vapor barrier can lead to insulation and system damage. Follow Us On Twitter http: Your Alert Profile lists the documents that will be monitored. 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.

Fibrous insulations are composed of small-diameter fibers that finely divide the air space. 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.
