This document specifies methods of quantitative analysis of various ternary mixtures of fibres.
The field of application of each method for analysing mixtures, specified in the parts of ISO 1833,
indicates the fibres to which the method is applicable.
This document is applicable to mixtures of fibres with more than three components provided that
the combination of test methods leads back to simple cases of fibre mixtures. Table B.1 illustrates the
typical ternary mixtures and their applied corresponding parts of the ISO 1833 series.

This document specifies a common method for the quantitative chemical analysis of various mixtures
of fibres. This method and the methods described in the other parts of ISO 1833 are applicable, in

scope of the appropriate part.

EN-ISO 1833-17 specifies a method, using concentrated sulfuric acid, to determinethe mass percentage of chlorofibres and certain other fibres, after removal ofnon-fibrous material, in textiles made of mixtures of - cotton, viscose, cupro,modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester,certain acrylic and certain modacrylic fibres with - chlorofibres (based onhomopolymers of vinyl chloride), polypropylene, elastolefin, melamine andpolypropylene/polyamide bicomponent. The modacrylics concerned are those whichgive a clear solution when immersed in concentrated sulfuric acid. This methodcan be used, particularly in place of the methods described in ISO 1833-12 andISO 1833-13, in all cases where a preliminary test shows that the chlorofibresdo not dissolve completely either in dimethylformamide or in the azeotropicmixture of carbon disulfide and acetone.

This Standard describes a pneumatic pressure method for the determination of bursting strength and bursting distension of textile fabrics. The method is applicable to knitted, woven, nonwoven and laminated fabrics. It can be suitable for fabrics produced by other techniques. The test is suitable for test specimens in the conditioned or wet state. From the available data there appears to be no significant difference in the bursting strength results achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This pressure range covers the majority of performance levels expected of general apparel.

This Standard describes a hydraulic method for the determination of bursting strength and bursting distension of textile fabrics. In this document, a hydraulic pressure is applied using a constant rate of pumping device. The method is applicable to knitted, woven, nonwoven and laminated fabrics. It can be suitable for fabrics produced by other techniques. The test is suitable for test specimens in the conditioned or wet state. From the available data, there appears to be no significant difference in the bursting strength results achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This pressure range covers the majority of performance levels expected of general apparel. For speciality textiles requiring high bursting pressures, the hydraulic apparatus is more suitable.
