Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.
Fibrous insulations are composed of small-diameter fibers that finely divide the air space. 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.
Awtm 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 awtm held together by a binder. Work Atm s – proposed revisions of this standard.
These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations. The pipe insulation may be molded asfm precision v-grooved with one or more walls split longitudinally and used up to a specified temperature.
ASTM C – 12 Standard Specification for Mineral Fiber Pipe Insulation
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide aztm air space.
The standard contains five types astmm primarily by maximum use temperature. This standard contains five types classified by maximum use temperature and thermal conductivity.
These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field. Each of these types is further classified by compressive resistance. These products are supplied in rigid and semi-rigid board form. The specified maximum thermal conductivity for all types is 0.
Historical Version s – view previous versions of standard. Mineral Fiber Ast, and Mineral Wool.
This abstract is a brief summary of the referenced standard. Category 1 materials asfm no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value.
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. Mineral Fiber Block and Board.
ASTM C – 17 Standard Specification for Mineral Fiber Pipe Insulation
Refer to Practice C to aid material selection. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica.
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. The standard contains seven types classified by maximum use temperature and thermal conductivity. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. Follow Us On Twitter http: Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings.
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. 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 version of the standard. 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.

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.
The standard further classifies products by grade. These insulations are flexible and are normally supplied as batts or rolled blankets.
