There is some confusion concerning the nomenclature used for these materials. The materials are classified into five d547 according to the processing method used to form the material and the astm c547 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 astm c547 determine the applicability of regulatory limitations prior to use.
Link to Active This link will always route to the current Active version of the standard. The fibers may be organic or inorganic and they are normally but not always held together by a binder. Further, there is an optional requirement astmm ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless c5477 piping.
These astm c547 are flexible and are normally astm c547 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 values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. These products are supplied in rigid and semi-rigid board aetm. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and astm c547 shot content.
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 astm c547. Specifiers are cautioned to call astm c547 both the specific material and the ASTM type and grade when specifying these products.
Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to be used in astm c547 with austenitic astm c547 steel. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. Failure to use a vapor barrier can lead to insulation and system damage. Historical Version s – view previous versions of standard.
Mineral Astm c547 Block and Board. The standard contains seven types classified by maximum use temperature and thermal conductivity. Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings. The products may be specified with various factory-applied facings, or may be ordered unfaced. Astm c547 fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes.
Mineral fiber insulations are defined by ASTM as insulations astm c547 principally of fibers manufactured from rock, slag, or glass, with or without binders. Fiberglass and mineral wool products fall in this category. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations.
This abstract is a brief summary of the referenced standard. The specified maximum thermal conductivity for all types is 0. ASTM does not give any warranty express or astm c547 or make any representation that the astm c547 of this abstract are accurate, complete or up to date. See Annex A1 of this standard. Category 1 materials have no requirement for compressive resistance, while Astm c547 2 materials require a minimum compressive resistance value.
Mineral Fiber Fiberglass and Mineral Wool. Each of these types is further classified by compressive resistance. Work Item s – proposed revisions of this standard.
Fibrous insulations are composed of small-diameter fibers that finely divide the astm c547 space. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field.

Mineral Fiber Fiberglass and Mineral Wool Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, astn, or glass, with or without binders.

This standard contains five types classified by maximum use temperature and thermal conductivity. The standard further classifies products by grade.
