(Specification)Standard Specification for Vermiculite Loose Fill Thermal Insulation
Standard Specification for Vermiculite Loose Fill Thermal Insulation
ABSTRACT
This specification covers the chemical and physical property requirements and acceptability testing procedures of expanded or exfoliated vermiculite loose fill thermal insulation. This also includes vermiculite that has been surface-treated to produce water repellency for use in installations where liquid moisture may be a factor. Vermiculite insulation is specified by two types according to treatments and five classes according to the range of particle size distribution. The insulation should conform to the specified values of bulk density, grading, water properties, thermal resistance, moisture absorption, combustibility, and surface-burning characteristics. Tests to determine the physical properties should also be in accordance with the specified test procedures.
SCOPE
1.1 This specification covers the composition and physical properties of expanded or exfoliated vermiculite loose fill insulation. The specification also includes the testing procedures by which the acceptability of the material may be determined. These testing procedures deal primarily with material performance in the temperature range associated with the thermal envelope of buildings; however, the commercially usable temperature range for this insulation is from -119 to 850°F (-84 to 454°C). For specialized applications, refer to manufacturer's instructions.
1.2 The specification also covers the composition and properties of vermiculite that has been surface-treated to produce water repellency for installations where liquid moisture may be a factor.
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, and shall also recommend protective measures to be employed in their safe utilization.
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 9, 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. For specific hazard statements, see Section 12.
