Описание (английский):

Applicable for textile materials in all forms. No single technique of sampling can be devised that will serve in all circumstances. General terms and their definitions are given. A lot of different sampling methods are described (e.g. for bast fibres, cotton fibres, man-made staple fibres, and wool fibres). The determination of the number of individuals to be tested in dependence on the variability of the material and the accuracy required is given in the annex.

Overview

ISO 1130:1975 - Textile fibres: Some methods of sampling for testing - defines accepted techniques for preparing representative laboratory samples of textile fibres in all forms. The standard recognizes that “no single technique of sampling will serve in all circumstances” and therefore presents a selection of numerical sampling, zoning, and other practical procedures for bast fibres, cotton, man‑made staple fibres and wool. An annex and tables give guidance on determining the number of individual fibres to test based on material variability and required accuracy.

Key topics and requirements

Scope and definitions: Clear definitions for terms such as individual, population, laboratory sample, laboratory test sample, test specimen, numerical sample and length‑biased sample.

Sampling strategies:

Numerical sampling (each fibre equal chance) vs length‑biased sampling (not covered).
Zoning to address population variation between parts (e.g., bale layers or fleece zones).

Procedures by fibre type:

Bast fibres (flax, hemp, jute, kenaf): different handling and sampling methods for raw and dressed material.
Cotton: methods for small bulks, single bales, multiple bales, processed material (sliver, roving, yarn, cloth) and practical rules (e.g., taking tufts from layers, selecting threads across fabric width).
Man‑made staple fibres: sampling bales and preparing representative final samples.
Wool: zoning methods for loose wool and handling within‑fleece and between‑fleece variability.

Sample preparation:

Guidance on forming laboratory samples (typical convenient sizes given), and mechanical blending preferred for small, homogeneous test samples (manual blending methods also described).

Statistical guidance: Annex provides a method to determine the number of individuals to test according to material variability and desired confidence/accuracy.

Practical applications

Prepare representative laboratory samples for fibre testing (strength, fineness, length distribution, micronaire, etc.).

Standardize sampling practices across suppliers, mills, testing laboratories and quality control departments.

Reduce sampling bias when assessing consignments (bales, bags, yarn packages, fabric rolls) or preparing test specimens for instrumented measurements.
