Nickel release testing from textile fasteners and buttons
In today’s increasingly conscious consumer environment, material safety is a critical concern. Among the many materials used in textiles for clothing, accessories, and other products, nickel is one of the most widely encountered metals due to its durability, affordability, and aesthetic appeal.
However, the release of nickel from fasteners and buttons can pose significant health risks, particularly to individuals with nickel allergies. The European Union’s Restriction on Hazardous Substances (RoHS) Directive 2011/65/EU and the REACH Regulation have stringent requirements for the release of heavy metals like nickel in consumer products.
Nickel release testing is a fundamental part of ensuring compliance with these regulations. This testing involves extracting nickel from fasteners or buttons using a standardized solution, typically acetic acid (2%) at 37°C for one hour. The extract is then analyzed via either atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS), depending on the required sensitivity and detection limits.
The testing process begins with careful preparation of the sample, which may involve mechanical abrasion to ensure that all nickel-containing surfaces are exposed. The extract is then filtered through a 0.45 μm filter before analysis. This step ensures accurate quantification by removing any particulate matter that could interfere with the detection.
Compliance thresholds for nickel release vary depending on the product category and jurisdiction. For example, in Europe, the limit set by RoHS is 0.5 mg/dm² after 17 hours of wear (EN 12477). In the United States, the Federal Trade Commission (FTC) requires that products labeled as "hypoallergenic" or similar must not release more than 3 μg/cm² of nickel per week under specified conditions.
Our laboratory adheres to these stringent standards and provides clients with detailed reports that include the exact measurement results, comparison against regulatory limits, and recommendations for corrective actions if necessary. By offering this service, we help manufacturers ensure their products meet global safety standards and avoid costly recalls or legal issues.
The importance of nickel release testing extends beyond mere compliance; it also reflects a broader commitment to product quality and consumer safety. In an era where transparency and responsibility are key drivers in brand reputation, our testing service plays a vital role in maintaining trust with consumers who value the well-being of themselves and their families.
