EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 4590 testing. This international standard specifies a general procedure for determining the percentage by volume of open and closed cells of rigid porous plastics by first measuring the geometric volume and then the airtight volume of test specimens.
The procedure includes correction of the apparent open cell volume, taking into account the surface cells cut open during sample preparation. Three alternative methods (method 1, method 2a and method 2b) and associated apparatus for measuring impassable volume are indicated.
Determine the surface area S and the geometric volume Vg of several test specimens, each with a different geometric surface/volume ratio r.
The determination of the impermeable volume Vi is based on the application of the Boyle-Mariotte law to a gas confined to an undeformed chamber, first in the absence of a test sample and then in the presence of a test sample.
EUROLAB assists manufacturers with EN ISO 4590 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories.
