    Abstract

    This specification covers structural insulating board for general thermal insulating, fire-resistive, and marine bulkhead applications. The structural insulating boards shall be of the following types and grades: Types I and II and Grades 1; 2; 3; 4; 5; 6; 7; and 8. Calcium silicate structural insulating board shall be composed of hydrated calcium silicate with natural or man-made fibers or fillers, or a combination thereof. The following test methods shall be performed: dimensions and density; flexural strength; compressive strength; screw holding strength; apparent thermal conductivity; combustion characteristics; and maximum use temperatures.

    This abstract is a brief summary of the referenced standard. 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. 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.

    1. Scope

    1.1 This specification covers structural insulating board for general thermal insulating, fire-resistive, and marine bulkhead applications. The rigid, preformed structural insulating board is for use at temperatures up to 1700°F (927°C). For specific applications, the actual temperature limit shall be agreed upon between the manufacturer and the purchaser.

    1.2 The structural insulating board maintains its structural integrity after immersion in water.

    1.3 Rapid cycling over a wide temperature range is not recommended because of potential damage due to thermal shock.

    1.4 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 considered standard.

    1.5 This standard does not purport to address all of the safety concerns, if any, 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.

    1.6 When the installation or use of thermal insulation materials, accessories and systems, may pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the recommended use of the company's products, and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
