Full title and description

DIN EN ISO 17751-2 E 2014-08 — Textiles — Quantitative analysis of cashmere, wool, other speciality animal fibres and their blends — Part 2: Scanning electron microscopy method. This designation reflects the German/European adoption (E DIN EN ISO) of the draft/prEN ISO 17751-2 text issued in 2014 (date of issue July/August 2014).

Abstract

This document specifies a method for identification, qualitative and quantitative analysis of cashmere, wool, other specialty animal fibres and their blends using scanning electron microscopy (SEM). It applies to loose fibres, intermediate products and final products and describes sample preparation, imaging and counting/quantification procedures for fibre-type analysis. (Note: the 2014 national/European adoption was a draft/adopted prEN stage that was later superseded by subsequent ISO editions.)

General information

• Status: Withdrawn / superseded (national adoption of a 2014 prEN/DIS text).
• Publication date: 2014-08-01 (designation shown as 2014-08; date of issue / national adoption July–August 2014).
• Publisher: DIN (as the German national adoption of EN/ISO text; published under the E DIN EN ISO designation).
• ICS / categories: 59.060.10 (Natural fibres; textiles — fibre analysis).
• Edition / version: E DIN EN ISO 17751-2:2014-08 (national/European adoption of the ISO prEN/DIS text).
• Number of pages: Approximately 56–57 pages in the national/EN adoption edition (varies by national publisher formatting).

Scope

The standard defines an SEM-based procedure for the detection, identification and quantitative determination of cashmere, wool, other speciality animal fibres and their blends in fibre samples and textile products. It covers sample preparation, imaging settings, criteria for morphological identification, counting procedures and calculation of percentage composition by fibre type. The document is intended for laboratory testing and quality control, and does not prescribe limits for acceptance — users apply the method as part of a broader quality or conformity assessment.

Key topics and requirements

• Sample preparation protocols for SEM (mounting, coating, cross-sectioning where applicable).
• Imaging parameters and magnification guidance to reliably observe fibre surface morphology and scale patterns.
• Identification criteria for cashmere, wool and other specialty animal fibres based on morphological features visible in SEM.
• Counting and quantification procedures to calculate fibre composition percentages in blends.
• Reporting requirements: test conditions, magnifications, images, counts and calculation methods.
• Limitations and applicability notes (method suitability, operator expertise, detection limits and the need for complementary methods where applicable).

Typical use and users

Laboratories performing textile fibre identification and quantification, quality control teams in textile and apparel manufacturers, fibre traders, certification bodies and forensic/textile research institutes use this method. It is used when SEM-based morphological analysis is required to distinguish natural animal fibres (e.g., cashmere vs. wool) and to quantify blend proportions for labelling, quality assurance or investigation.

Related standards

ISO 17751 series (other parts covering complementary or alternative identification methods), national adoptions of EN/ISO 17751-2, and other textile-fibre analysis standards maintained by ISO/TC 38. The 2014 national/EN adoption was subsequently replaced by ISO 17751-2:2016 and later revised by ISO 17751-2:2023 (current international edition for the SEM method).

FAQ

Q: What is this standard?

A: It is the German/European designation (E DIN EN ISO 17751-2:2014-08) of the draft/prEN ISO method for SEM-based quantitative analysis of cashmere, wool and other specialty animal fibres. This national adoption reflects the 2014 prEN/DIS stage rather than the later confirmed ISO editions.

Q: What does it cover?

A: The document specifies procedures for sample preparation, SEM imaging, morphological identification of animal fibres and counting/quantification methods to determine blend percentages. It is a laboratory method for fibre analysis and reporting.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers and quality-control personnel, fibre traders, certification bodies and research institutions who need a robust SEM method to identify and quantify animal-fibre content in raw or processed textile materials.

Q: Is it current or superseded?

A: The 2014 national/EN adoption is withdrawn/superseded. The ISO method was published in ISO 17751-2:2016 and later revised to ISO 17751-2:2023; users should refer to the latest ISO edition (2023) for the current, authoritative international text.

Q: Is it part of a series?

A: Yes — ISO 17751 is a series covering quantitative analysis of cashmere, wool and related specialty animal fibres; Part 2 specifically addresses the SEM method and other parts in the series describe alternative or complementary techniques.

Q: What are the key keywords?

A: Cashmere, wool, specialty animal fibres, SEM, quantitative analysis, fibre blends, textile testing, ISO 17751-2, DIN EN ISO.
