ASTM C1484-09

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Specification for

Vacuum Insulation Panels
This standard is issued under the fixed designation C 1484; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, 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.
1. Scope
1.1 This specification covers the general requirements for Vacuum Insulation Panels (VIP). These panels have been used
wherever high thermal resistance is desired in confined space applications, such as transportation, equipment, and appliances.
1.2 Vacuum panels typically exhibit an edge effect due to differences between panel core and panel barrier thermal properties.

87 to 870 m·K/W (12.5 to 125 hr·ft ·°F/Btu·in) at 24°C (75°F) mean, and whose intended service temperature boundaries range
from –70 to 480°C (–94 to 900°F). ) typically range from 87 to 870 m·K/Wat 24°C mean, and whose intended service temperature
boundaries range from –70 to 480°C.
1.3 The specification applies to panels encompassing evacuated space with: some means of preventing panel collapse due to
atmospheric pressure, some means of reducing radiation heat transfer, and some means of reducing the mean free path of the
remaining gas molecules.
1.4 Limitations
1.4.1 The specification is intended for evacuated planar composites; it does not apply to non-planar evacuated self-supporting
structures, such as containers or bottles with evacuated walls.
1.4.2 The specification describes the thermal performance considerations in the use of these insulations. Because this market
is still developing, discrete classes of products have not yet been defined and standard performance values are not yet available.
1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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 specifications and determine the applicability of regulatory
limitations prior to use. For specific safety considerations see Annex A1.
