Overview

EN 16711-2:2015 is a European standard developed by CEN that specifies a standardized method for determining the metal content extracted from textiles using an acidic artificial perspiration solution. This standard targets the measurement of metals including antimony (Sb), arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), mercury (Hg), and nickel (Ni) in both natural and synthetic textiles. The scope covers various textile products, such as coated fabrics and garment components like buttons and zips.

This procedure is critical for assessing metal exposure that may occur through skin contact, simulating perspiration conditions to evaluate metal release from textile materials. The standard is widely adopted across European countries, ensuring consistent safety and quality testing in the textile industry.

Key Topics

• Extraction Procedure
  The method involves cutting a representative textile specimen into small pieces and extracting soluble metals by immersion in an acidic artificial perspiration solution at 37 ± 2 °C. The solution mimics the chemical properties of human sweat including pH adjustment, enabling realistic simulation of metal leaching during actual wear.

• Metals Analyzed
  The standard covers ten hazardous or regulated metals: Sb, As, Cd, Cr, Co, Cu, Pb, Hg, and Ni. These metals are often scrutinized because of their potential health risks when in prolonged contact with skin.

• Analytical Techniques
  Post-extraction, metal quantification employs sensitive analytical methods such as:

  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
  • Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
  • Atomic Absorption Spectrometry (AAS) including cold vapour technique for mercury

• Sampling and Preparation
  The sampling guidelines emphasize representative sub-sampling of textile parts, including all material components and colors. To avoid contamination, sharp ceramic scissors are recommended for cutting samples without metallic contact.

• Method Reliability
  The standard reports on the method’s accuracy and precision based on interlaboratory studies, highlighting acceptable trueness and system precision in line with ISO 5725. It provides data on limits of detection and quantification, ensuring robust, reproducible testing.

• Reporting Requirements
  Test reports must clearly state laboratory details, method specifications, sample description, and quantitative metal amounts expressed in milligrams per kilogram (mg/kg), including any deviations from the standard.

Applications

• Textile Safety Testing
  EN 16711-2:2015 is essential for manufacturers and regulatory bodies to evaluate and control the release of harmful metals from textiles during consumer use, particularly garments worn close to the skin.

• Compliance with Regulations
  This standard supports adherence to chemical safety regulations such as the European REACH regulation and other global requirements focused on restricting hazardous substances in consumer products.

• Quality Control
  Textile producers use this method to screen raw materials, semi-finished, and finished products to ensure metal contents are within safe limits, preventing adverse health effects and potential legal issues.

• Research and Development
  R&D laboratories rely on this standard for assessing the impact of different textile treatments, dyes, and coatings on metal release, facilitating safer product innovation.

Related Standards

• EN 16711-1: Determination of metals using microwave digestion-complements Part 2 by analyzing total metal content rather than extractable metals through perspiration simulation.

• EN ISO 105-E04: Tests for color fastness to perspiration-provides the basis for preparation of artificial perspiration solutions used in the extraction process.

• EN ISO 11885 / EN ISO 17294-2: Methods for elemental analysis by ICP-OES and ICP-MS-used for metal quantification in the extraction solutions.

• EN ISO 3071: Determination of pH of aqueous extract-relevant for ensuring the perspiration solution maintains the correct acidity during extraction.

By following EN 16711-2:2015, textile manufacturers and testing laboratories can effectively assess metal leaching from textiles under simulated sweating conditions, ensuring consumer safety and regulatory compliance. The method’s standardized approach enables reliable, comparable results across various textiles and metal types, promoting transparency and quality in the textile industry.
