The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.
This abstract is asrm brief summary of the referenced standard.
Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value.

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. Each of these types is further classified by compressive resistance. The standard contains seven types classified by maximum use temperature and thermal conductivity. The products may be specified with various factory-applied facings, or may be ordered unfaced.
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. All products should conform to the required values of satm surface performance, non-fibrous content, use temperature, sag resistance, linear shrinkage, water vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean temperature.
You may delete a document from your Alert Profile at any time. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. Standards Subsctiption may be the perfect solution.
The specified maximum thermal conductivity for all types is 0. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space. 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. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
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 sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.

These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations. These products are supplied in rigid and semi-rigid board form. You can download and open this file to your own computer but DRM prevents opening satm file on another computer, including a networked server. Work Item s – proposed revisions of this standard.

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.
These insulations are flexible and c57 normally supplied as batts or rolled blankets.
