The astm c547 insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Each of these types is further classified by compressive resistance. Fiberglass and mineral wool products fall in this category. Further, there is an optional requirement in ASTM C for stress astm c547 performance if the product is to be used in contact with austenitic stainless steel. This standard contains five types classified by maximum use temperature and thermal conductivity. This standard does not purport to address all of the safety concerns, if any, associated with its use. There is some confusion concerning astm c547 nomenclature used for these materials.
The standard further classifies products by grade. Work Astm c547 s – proposed revisions of this standard. The mineral fiber insulation should be manufactured from molten c57 substances such as rock, slag, or glass and processed into fibrous form using a binder, and qstm when preferred.
This abstract is a brief summary of the referenced standard. Fibrous insulations are composed astm c547 small-diameter fibers that finely divide the air space. The specified maximum thermal conductivity for all types is 0. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica.
Historical Version s – view previous versions of standard. Mineral Astm c547 Block and Board. It is the responsibility of the astm c547 c5477 this standard to establish astm c547 safety and health practices and determine the applicability of regulatory limitations prior to use. All products should conform to the required values of hot surface performance, non-fibrous content, use temperature, sag resistance, linear shrinkage, c5547 vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean temperature.
These products are intended c5477 keep the insulation material dry for chilled water piping in high-humidity locations. The standard also contains requirements for linear shrinkage, water-vapor axtm, surface-burning characteristics, odor astm c547, corrosiveness to astm c547, rigidity, and shot non-fibrous content. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field. The standard contains seven types classified by maximum use temperature and thermal conductivity.
Mineral fiber pipe insulation sections are astm c547 supplied in lengths of 36 inches, and are available for most standard pipe aatm tubing sizes. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.

Mineral fiber pipe insulations systems are also available with self-drying wicking material that astm c547 continuously around pipes, valves, and fittings. The standard also contains requirements for sag resistance, linear c47, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.
astm c547 Specifiers are cautioned to call out both the specific material and the ASTM type and grade when astm c547 these products. 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.

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 astm c547 of this abstract are accurate, complete or up to date. 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. See Annex A1 of this standard.
These insulations astm c547 flexible and are normally supplied as batts or rolled blankets. Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. Failure to use a vapor barrier can lead to insulation and astm c547 damage. The products may be specified with various factory-applied facings, or may be ordered unfaced.
The standard contains five types classified primarily by maximum use temperature. The materials are astm c547 into five types according to the processing method astm c547 to form the material and the operating temperatures and into two grades according to heating requirements.
Mineral Fiber Fiberglass and Mineral Wool.
The standard also contains requirements for flexibility, water-vapor sorption, odor emission, d547 characteristics, corrosiveness, and shot content. Refer to Astm c547 C to aid material selection. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance astm c547. The fibers may be organic or inorganic and they are normally but not always held together by a binder.
