Описание (английский):

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 general, to fibres in any textile form. Where certain textile forms are excepted, these are listed in the scope of the appropriate part.

Overview

EN ISO 1833-1:2020 - Textiles - Quantitative chemical analysis - Part 1: General principles of testing - establishes the common principles for determining the quantitative composition of fibre mixtures. Published by CEN as an endorsed adoption of ISO 1833-1:2020, this part sets out general rules and procedures to be used together with the specific test methods in other parts of the ISO 1833 series.

Key topics and technical requirements

Scope and principle

Defines a common approach for the quantitative chemical analysis of various fibre mixtures in any textile form (except where specific parts exclude certain forms).
Main analytical approaches: chemical (selective dissolution) and manual separation (Annex B), with manual separation preferred when applicable.

Pre-treatment and removal of non-fibrous matter

Requires removal of oils, waxes, dressings and water‑soluble matter before analysis (methods in Annex A, now normative).
Dye is normally considered part of the fibre and is not removed.

Conditioning, sampling and sample preparation

Specifies conditioning and testing atmosphere, sampling rules, and pre-treatment of laboratory test samples to ensure representative results.

Reagents, apparatus and handling

Lists general reagent and apparatus requirements (including stoppered weighing bottles) and handling/drying/cooling/weighing instructions to ensure accurate dry‑mass determinations.

Testing execution, calculation and reporting

Procedures for executing tests, calculating proportions from mass loss after selective dissolution, addressing cases where calculated percentages exceed 100 %, and requirements for precision and test reporting.

Precision and annexes

Addresses method precision and includes normative annexes for pre-treatment (A) and manual separation (B).

Practical applications and users

Who uses it: textile laboratories, quality control teams, fibre and yarn manufacturers, testing houses, regulatory bodies and R&D groups involved in fibre composition verification.

Why use it: to obtain reliable, standardized determinations of fibre blend composition for compliance, labeling, quality assurance, dispute resolution and product development.

Use cases: verifying declared fibre content on garments, analysing mixed-fibre yarns and fabrics, evaluating production blends, and supporting conformity assessments under regional or contractual requirements.
