Plastics — Film and sheeting — Determination of average thickness of a sample, and average thickness and yield of a roll, by gravimetric techniques (gravimetric thickness)

Plastiques — Film et feuille — Détermination de l'épaisseur moyenne d'un échantillon, et de l'épaisseur moyenne d'un rouleau, ainsi que de sa surface par unité de masse, par mesures gravimétriques (épaisseur gravimétrique)

Abstract / scope

Applies to all plastics films and sheeting and has special value when mechanical scanning is not sufficiently precise, particularly for measuring the thickness of embossed sheeting. The gravimetric thickness is calculated from measurements of mass, area and density of a sample.
