DESCRIPTION

BS 2782-6:Methods 620A to 620D:1991


This standard BS 2782-6:Methods 620A to 620D:1991 Methods of testing plastics. Dimensional properties is classified in these ICS categories:
  • 83.080.01 Plastics in general

1.1 This International Standard specifies four methods for the determination of the density and relative density of non-cellular plastics in the form of sheet, film, tube, moulded objects, and moulding powders, granules and pellets.

– Method A

Immersion method for plastics in a finished condition, whether machined or otherwise formed (see 5.1.3), but not powders.

– Method B

Pyknometer method for plastics in the form of powder, granules, pellets, flake or moulded articles reduced to small particles.

– Method C

Titration method for plastics in forms similar to those required for method A, including pellets.

– Method D

Density gradient column method for plastics in forms similar to those required for method A, and including pellets. Density gradient columns are columns of liquid, the densities of which increase uniformly from top to bottom. They are particularly suited to measurement of small samples of products and to comparison of densities.
