ASTM C196-00(2005)

Standard Specification for Expanded or Exfoliated Vermiculite Thermal Insulating Cement

ABSTRACT
This specification covers expanded or exfoliated vermiculite thermal insulating material in the form of dry cement or plaster, intended to be mixed with a suitable proportion of water, applied as a plastic mass, and dried in place, for use as insulation on surfaces. The cement shall be composed predominantly of expanded or exfoliated vermiculite, with a suitable proportion of heat-resistant binder. The following requirements are employed for purposes of initial material or product qualification: consistency, compressive strength, linear shrinkage, apparent thermal conductivity, and dry adhesion to steel. The consistency of the material, dry converting capacity and volume change upon drying, compressive strength, linear shrinkage, apparent thermal conductivity, and dry adhesion to steel shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers expanded or exfoliated vermiculite thermal insulating material in the form of dry cement or plaster, intended to be mixed with a suitable proportion of water, applied as a plastic mass, and dried in place, for use as insulation on surfaces operating at temperatures between 100°F (38°C) and 1800°F (982°C). The cement shall not be used where it will be exposed to combustion conditions, such as the hot face lining of a furnace.
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units are given in parentheses and may be approximate.
The following safety hazards caveat pertains only to the test method portion, Section , of this specification. 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.
1.3 When the installation or use of thermal insulation materials, accessories and systems, may pose safety or health problems, the manufacturer shall provide the user with appropriate current information regarding any known problems associated with the recommended use of the company's products. The manufacturer shall also recommend protective measures to be employed in the safe utilization of said products.
