Detailed Standards Coverage

EN ISO 25202:2026 – Determination of Glutaraldehyde Content in Leather

Leather – Chemical analysis – Determination of glutaraldehyde content (ISO 25202:2026)

This dual-identical adoption by CEN and ISO delivers a harmonized method for determining free and released glutaraldehyde in leathers using liquid chromatography (LC). Glutaraldehyde is a popular tanning agent but poses safety, environmental, and quality challenges due to its chemical reactivity and potential residues in finished leather products.

The standard outlines:

• Preparation and extraction of leather test specimens
• Reaction with 2,4-dinitrophenylhydrazine (DNPH) for derivative formation
• Chromatographic determination and result expression

Scope: Applies to chemical testing of any tanned leather where glutaraldehyde is used or suspected. The method enhances product traceability and aligns with both regulatory and customer-driven requirements for chemical transparency.

Key requirements:

• Sampling in accordance with ISO 2418 and ISO 4044 guidelines
• Extraction and derivatization steps to isolate glutaraldehyde
• Use of precision liquid chromatography
• Detailed reporting including test conditions and calculations

Who should comply: Leather manufacturers, tanneries, chemical testing laboratories, and brands requiring proof of chemical compliance in their finished products.

Practical implications: Routine adoption supports safer product development, faster regulatory clearances for export markets, and reduced risk of recalls due to non-compliance with chemical content restrictions. Consistent testing methodology helps ensure uniformity in global supply chains.

Key highlights:

• Harmonized method recognized across Europe and internationally
• Supports assessment of occupational and product safety
• Provides robust documentation for regulatory and customer audits

ISO/TS 24858:2026 – Eddy Current Testing of Spread Carbon Fibre Tows

Plastics — Conducting materials — Eddy current measurement on spread carbon fibre tow

Electrically conductive fibres—such as carbon fibre tow—are critical for the next generation of light-weight composites, e-textiles, and smart materials. This technical specification sets out a standardized method using non-contact eddy current measurement to evaluate the homogeneity (uniform electrical properties) of spread carbon fibre tows.

Scope: The method measures impedance across the fibre width, calculating the standard deviation as a marker of uniformity. This is vital for material quality control, especially where local inhomogeneity can diminish mechanical or electronic performance.

Key requirements:

• Precise sample preparation, avoiding resin impregnation
• Use of appropriate probes and apparatus to minimize measurement error
• Testing procedures standardized for temperature, humidity, and probe gap (<1 mm)
• Continuous measurement and statistical evaluation of impedance
• Detailed test reporting, including environmental conditions and equipment calibration

Target audience: Manufacturers and converters of carbon fibre tow, quality assurance labs, R&D teams developing advanced composites, automotive and aerospace suppliers, and those in smart textile and e-fabric sectors.

Practical implications: The method supplements optical analysis by assessing thickness uniformity—not just surface alignment—allowing for earlier defect detection and less material waste. Uniform measurement criteria also facilitate acceptance of materials across borders and by international OEMs.

Key highlights:

• Reliable, non-contact evaluation of conductive fibre homogeneity
• Facilitates high-quality composite and electronic textile production
• Enables continuous in-line quality assurance

ISO 24304:2026 – Biodegradation Testing of Textiles in Seawater

Textiles — Determination of the aerobic biodegradation of textile materials in seawater

Sustainability is at the core of modern textile development, with marine environments under particular scrutiny. ISO 24304:2026 introduces the first comprehensive laboratory procedure for evaluating how textile materials biodegrade under aerobic (oxygen-rich) conditions in seawater.

Scope: Designed for staple fibres, yarns, tops, and fabrics, this test simulates the pelagic, or surface, marine environment. It measures:

• The biochemical oxygen demand (BOD) indicating microorganism activity
• Amount of carbon dioxide evolved, correlating to organic carbon decomposition

This method enables direct comparison of biodegradable potential between different textiles—essential data for eco-labels, product design, and regulatory claims.

Key requirements:

• Preparation of seawater (with/without sediment) and textile samples
• Controlled incubation (typically (20 ± 2) °C, in darkness or diffuse light)
• Validated apparatus for BOD and CO₂ measurement
• Test periods up to one year to replicate environmental exposure
• Detailed calculation and reporting of both absolute and relative biodegradation

Who must comply: Textile mills, yarn spinners, R&D labs, eco-design engineers, compliance officers involved in environmental product declarations or seeking marine degradability certifications (note: not for anaerobic conditions or deep-sea simulation).

Practical implications: Supports valid comparative studies, underpins sustainability initiatives, guides material selection for marine-sensitive markets (like fisheries or ocean gear), and prepares organizations for increasingly stringent environmental regulations.

Key highlights:

• Fills critical gap in measuring marine biodegradability of textiles
• Rigorous, reproducible, and globally applicable methodology
• Supports lifecycle assessment, EPDs, and eco-innovation

Leather — Chemical analysis — Determination of glutaraldehyde content

This international standard, identical in technical content to EN ISO 25202:2026, establishes a trusted protocol for glutaraldehyde quantification in leather. Using liquid chromatography, it allows users to determine both free and released glutaraldehyde—critical for assessing both product safety and environmental impact.

Scope: Any segment of the leather supply chain—from raw hides to finished goods—can utilize this method to document chemical levels and demonstrate due diligence in line with product safety expectations (especially important for regulated markets and green procurement).

Key requirements:

• Conformance with specimen preparation standards (ISO 2418, ISO 4044)
• Accurate extraction and chemical derivatization
• Chromatographic separation and quantitative determination
• Precision benchmarks for repeatability and reproducibility
• Standardized result reporting and documentation

Target organizations: Tanneries, quality control labs, brands with supply chain transparency and chemical management mandates, third-party certifiers.

Practical implications: Essential for quality assurance teams looking to minimize toxicological risk, improve traceability, and avoid failed safety audits or product recalls. Also critical for meeting restricted substance lists (RSLs) in the leather industry.

Key highlights:

• International standardization ensures global recognition
• Supports compliance with chemical regulations in consumer and professional leather goods
• Detailed method supports robust quality management systems
