1、Designation:C553 13 Standard Specication for Mineral Fiber Blanket Thermal Insulation for Commercial and Industrial Applications 1 This standard is issued under the xed designation C553; the number immediately following the designation indicates the year of original adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope 1.1 Thisspecicationc
3、overstheclassication,composition, physical properties, and dimensions of mineral ber (rock, slag, or glass) blanket intended for use as thermal insulation on surfaces operating at temperatures between 0F (-18C) and 1200F (649C). For specic applications, the actual tempera- ture limits shall be agree
4、d upon between the supplier and the purchaser. 1.2 The orientation of the bers within the blanket is primarily parallel to the principal surface (face). This speci- cation does not cover fabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide a ber orient
5、ation that is perpendicular to the surface (face). 1.3 For satisfactory performance, properly installed protec- tivevaporretardersmustbeusedinbelowambienttemperature applications to reduce movement of water vapor through or around the insulation towards the colder surface. Failure to use a vapor ret
6、arder can lead to insulation and system damage. Refer to Practice C921 to aid material selection. Although vapor retarders are not part of this specication, properties required in Specication C1136 are pertinent to application or performance. 1.4 This standard does not purport to provide the perfor-
7、 mance requirements of hourly-rated re systems. Consult the manufacturer for the appropriate system. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not c
8、onsidered standard. 1.6 This standard does not purport to address all of the safety concerns associated with its use. 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. 2.
