Abstract

Specifies test methods for rigid cellular plastics.

Scope

This Standard sets out a method for determining the dimensional stability of rigid cellular plastics when subjected to specific conditions of temperature and relative humidity.
The method suggests a range of conditions from which one or more of the desired test conditions can be selected.
NOTES:
1 Additional conditions may be used as agreed upon by the purchaser and supplier.
2 The term 'dimensional stability of a rigid cellular plastic' implies the absence of irreversible change in dimensions in each of three directions perpendicular to each other when a test specimen of specified size is exposed to stated conditions for a specified period. In practice, such irreversible changes do occur and are measured by the method described in this Standard.
