Historical Standard: ASTM D3576-98 Standard Test Method for Cell Size of Rigid Cellular Plastics
SUPERSEDED (see Active link, below)
ASTM D3576
1. Scope
1.1 This test method covers the determination of the apparent cell size of rigid cellular plastics by counting the number of cell-wall intersections in a specified distance.
1.2 Procedure A requires the preparation of a thin slice, not more than one half the average cell diameter in thickness, that is mechanically stable. For most rigid cellular plastics this limits the test method to materials with an average cell size of at least 0.2 mm.
1.3 Procedure B is intended for use with materials whose friable nature makes it difficult to obtain a thin slice for viewing.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
Note 1-The annex to ISO 2896 is technically equivalent to this test method.
