What is ISO 1600 – Light absorption on moulded specimens of cellulose acetate about?
ISO 1600 is an International Standard that discusses cellulose acetate. The main objective of ISO 1600 is to provide manufacturers with best industry methods to determine the performance and quality of cellulose acetate.
ISO 1600 specifies a method for the determination of light absorption of cellulose acetate, employing test specimens taken from two mouldings that have been produced using different periods of heating.
ISO 1600 is intended for cellulose acetate having an acetic acid yield of 54 % ± 2,5 %. It may also be applicable to other transparent plastics which are not strongly coloured and which can be moulded under the specified conditions.
Who is ISO 1600 - Light absorption on moulded specimens of cellulose acetate for?
ISO 1600 on cellulose acetate is relevant to:
- Plastic industry
- Product design engineers
- Product development teams
- Quality control and testing authorities
Why should you use ISO 1600 - Light absorption on moulded specimens of cellulose acetate?
The aim of ISO 1600 is to provide quantitative measurements which are compatible with visual judgements of yellowness and lightness, and of changes in these properties after moulding.
The determinations are carried out on cellulose acetate in plasticized form rather than in solution, since a more reliable guide is thereby obtained to the performance of cellulose acetate in plastics materials.
The method mentioned in ISO 1600 thus minimizes the effects of haze or imperfections in the specimens.
