General Information
- Abstract
This document specifies a method, using glacial acetic acid, to determine the mass percentage of acetate, after removal of non-fibrous matter, in textiles made of mixtures of
— acetate
with
— certain chlorofibres or after-chlorinated chlorofibres.
It is also possible to analyse mixtures containing acetate by using the test methods described in ISO 1833-3 or ISO 1833-9.

Overview
EN ISO 1833-14:2019 specifies a quantitative chemical analysis method for determining the mass percentage of acetate in textile mixtures containing acetate and certain chlorofibres (including after-chlorinated chlorofibres). The method uses glacial acetic acid to dissolve acetate and follows the general principles given in ISO 1833-1. It applies after removal of non-fibrous matter and is intended for reliable composition determination to support quality control and regulatory compliance.
Key Topics
- Scope: Analysis of mixtures of acetate with specified chlorofibres or after-chlorinated chlorofibres; alternative methods include ISO 1833-3 and ISO 1833-9 for different solvent systems.
- Principle: Acetate is dissolved from a known dry mass of the specimen using glacial acetic acid. The insoluble residue is collected, washed, dried and weighed; the acetate percentage is calculated by difference.
- Reagents: Uses reagents from ISO 1833-1 plus glacial acetic acid (boiling point between 116 °C and 119 °C). A safety note emphasizes that this reagent is harmful and requires full precautions during use.
- Apparatus: Uses the apparatus described in ISO 1833-1 together with a glass-stoppered conical flask (minimum 200 ml) and a mechanical shaker.
- Test procedure highlights:
- Add 100 ml of glacial acetic acid per gram of specimen.
- Shake for (20 ± 1) min on a mechanical shaker.
- Perform three extractions in total, decanting through a weighed filter crucible.
- Rinse crucible and residue with 100 ml acetic acid and then three times with water; allow ~2 min gravity drainage after each rinse before suction.
- Dry, cool and weigh the crucible and residue.
- Calculation: Follow ISO 1833-1 general instructions; the method specifies a value of d = 1,00 for the calculation.
- Precision: On homogeneous mixtures, results have confidence limits not greater than ±1 percentage point at the 95% confidence level.
Applications
- Routine quality control and incoming material inspection in textile manufacturing.
- Verification of labelling and composition claims for blended fabrics containing acetate and chlorofibres.
- Analytical reference method in textile testing laboratories where glacial acetic acid extraction is preferred.
- Useful for research and development when assessing blend ratios or processing effects on acetate content.
Practical considerations:
- Observe safety procedures when handling glacial acetic acid and dispose of acidic waste per local regulations.
- Follow ISO 1833-1 for sample preparation, removal of non-fibrous matter and calculation conventions to ensure comparability.
Related Standards
- ISO 1833-1: General principles of testing and calculation rules.
- ISO 1833-3: Alternative method for acetate mixtures (acetone-based).
- ISO 1833-9: Alternative method for acetate/triacetate mixtures (benzyl alcohol-based).
- Other parts of the ISO 1833 series provide methods for different fibre combinations and solvent systems.
This standard is endorsed as EN ISO 1833-14:2019 by CEN and is intended for national adoption to harmonize textile composition testing across member countries.
