Rigid cellular plastics - Determination of the volume percentage of open cells and of closed cells

active, Most Current
Organization: CEN
Publication Date: 1 August 2016
Status: active
Page Count: 34
ICS Code (Cellular materials): 83.100
scope:

This International Standard specifies a general procedure for the determination of the volume percentage of open and of closed cells of rigid cellular plastics, by measurement first of the geometrical volume and then of the air-impenetrable volume of test specimens.

The procedure includes the correction of the apparent open-cell volume by taking into account the surface cells opened by cutting during specimen preparation. Three alternative methods (method 1, method 2a and method 2b), and corresponding apparatus, are specified for the measurement of the impenetrable volume.
