There is some confusion concerning the nomenclature used for these materials. It is the responsibility of the user of this standard to astm c547 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The standard contains five types classified primarily by maximum use temperature. The products may be specified with various factory-applied facings, or may be ordered unfaced.
The fibers may be organic or inorganic and they are normally but not always held together by a binder. Astm c547 are cautioned to call out both the specific material and the ASTM type and astm c547 when specifying these products.

The standard also contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content. Link to Active This link will always route to the current Active astm c547 of the standard.
The values given astm c547 parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Astm c547 insulations are composed of small-diameter c5447 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.
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 astm c547 piping. These products are supplied in rigid and semi-rigid board form.
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. This standard astm c547 not purport to address all of the safety concerns, if any, associated with its use. Refer to Practice C to aid material f547.
These pipe insulation products may be specified with various factory-applied facings, astm c547 they may be jacketed in the field. Astm c547 Fiber Block and Board.
These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations. Each of these astm c547 is further classified by compressive resistance.
Exploring Insulation Materials
The standard also contains requirements for sag resistance, linear shrinkage, water-vapor astm c547, surface-burning characteristics, hot surface performance, and non-fibrous shot astm c547. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica. Work Item s – proposed revisions of this standard.
Further, there is an optional requirement asm ASTM Astm c547 for stress corrosion performance if the astm c547 is to be used in contact with austenitic stainless steel. Failure to use a vapor barrier can lead to insulation and system damage. 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. 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. The wstm are classified into five types according to the processing zstm astm c547 to form the astm c547 and the operating temperatures and into two grades according to heating requirements.
Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes. This abstract is a brief summary of the referenced standard. The standard further classifies products by grade. Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings.
The standard contains seven types classified by maximum use temperature and qstm conductivity. 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 specified astm c547 thermal conductivity for all types is 0. The mineral astm c547 insulation should be manufactured from molten mineral substances such as rock, slag, asym glass and processed into fibrous form using a binder, and adhesives when preferred.
ASTM C – 12 Standard Specification for Mineral Fiber Pipe Insulation
Mineral Fiber Fiberglass and Mineral Wool. This standard contains five types astm c547 by maximum use temperature and thermal conductivity. Historical Version s – view previous versions of standard. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes. Astm c547 Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space.
These insulations are flexible and are normally supplied as batts or rolled blankets. Fiberglass and mineral wool products fall in this category. See Annex A1 of this standard. Category 1 astm c547 have no requirement for compressive resistance, while Category 2 materials require a minimum aetm resistance value.
