Plastics - Cellulose acetate - Determination of light absorption on moulded specimens produced using different periods of heating (ISO 1600:1990)

This International Standard specifies a method for the determination of light absorption of cellulose acetate, employing test specimens taken from two mouldings which have been produced using different periods of heating. The aim 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. This method min imizes imperfections in th e spec i the mens effects of haze or This method is intended for cellulose acetate having an acetic acid yield of 54 % + 25 %. lt may also be applicable to other transparent plastics which are not strongly coloured and which tan be moulded under the specified conditions.

Frequently Asked Questions about ÖNORM EN ISO 1600

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
