UNE 53-213 Pt.1-1986 Plastic sheets and plastic pages. Determination of the average thickness of a sample by gravimetry (gravity thickness), e.g. efficiency of film
Section one of this standard describes a test method for determining the gravimetric thickness of a sample of plastic film or sheet. This method is applicable to all plastic films and sheets, and has special value when thickness determination by a scanning method is not sufficiently precise, such as in the case of embossed films and sheets.
