标准编号：ISO 1875:1982

中文名称：塑料.增塑的醋酸纤维素.用乙醚可萃取物质的测定

英文名称：Plastics — Plasticized cellulose acetate — Determination of matter extractable by diethyl ether

发布日期：1982-02

标准范围

该测定方法适用于任何形式的增塑醋酸纤维素，如模塑材料、板材、制成品。将塑化样品转化为薄膜，通过溶解和浇铸制备，然后在索氏仪器中用乙醚萃取。通过在真空下加热并称量残余物质来去除乙醚。

The determination method applies to plasticized cellulose acetate in any form, such as moulding material, sheet, manufactured articles. Conversion of the plastizised sample to a film, prepared by dissolving and casting, and subsequent extraction by ethylether in a Soxhlet apparatus. Removal of the ether by heating under vacuum and weighing the residual matter.
