1 Scope This standard specifies a method for determining the apparent overall density and the apparent core density of cellular plastics and rubbers. If the material to be tested includes skins formed during a molding/extrusion, the apparent overall density or the apparent core density, or both, can be determined. If the material does not have skins formed during molding, the term "overall density" is not applicable. For shaped materials, a different method such as buoyancy method may be used. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to (excluding amending errors in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of the normative document is applicable.
