ASTM C1729-10

Standard Specification for Aluminum Jacketing for Insulation

ABSTRACT
This specification covers aluminum jacketing for thermal and acoustical insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. It provides physical requirements for aluminum jacketing for thermal and acoustical insulation. Classification of aluminum jacketing is based on three factors: outer surface treatment and emittance, alloy and temper per Specification B209, and moisture retarder. The specification covers physical properties, minimum thickness for pipe jacketing, and permissible thickness tolerances. Test methods cover total hemispherical emittance, surface burning characteristics, metal sheet thickness, pinholes in moisture retarder, pencil hardness, and water vapor transmission rate of the moisture retarder.
SCOPE
1.1 This specification covers aluminum jacketing for thermal and acoustical insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. It does not cover insulation jacketing made from other materials such as mastics, fiber reinforced plastic, PVC, or stainless steel nor does it cover the details of thermal or acoustical insulation systems.
1.2 This specification provides physical requirements for aluminum jacketing for thermal and acoustical insulation. Guide C1423 provides guidance in selecting jacketing materials and their safe use.  
1.3 This is a material specification and does not imply any performance of the installed system using the materials specified herein.
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.
