Plastics - Unplasticized cellulose acetate - Determination of free acidity (ISO 1061:1990)

This International Standard specifies a rnethod for the determination of the amount of free acid in unplasticized cellulose acetate. The ft-ee acidity determined by this method includes acidity extractable by water and acidity due to acidic groups directly attached to the cellulose acetate, e-g. carboxyl groups. The latter is usually a very small proportion of the total. This method is not suitable for cellulose acetate containing any additives which may affect the test.

Häufige Fragen zu ÖNORM EN ISO 1061

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.
