EN ISO 14184:2011 is an international standard that provides guidelines and requirements for the determination of formaldehyde content in textiles. Formaldehyde is a chemical commonly used in textile manufacturing processes, such as fabric dyeing and finishing, to enhance certain properties or achieve desired effects. However, excessive formaldehyde levels in textiles can pose health risks.
Why is it important?
EN ISO 14184:2011 sets permissible limits for formaldehyde content in textiles to ensure consumer safety. Excessive exposure to formaldehyde can cause various health problems, including skin irritation, respiratory issues, and even carcinogenic effects. By complying with this standard, textile manufacturers and retailers can guarantee that their products adhere to stringent safety standards and protect consumers from potential harm.
How is formaldehyde content determined?
The standard outlines two methods for determining formaldehyde content in textiles:
Method A: This method involves extracting formaldehyde from the textile sample using water, followed by analysis using a colorimetric technique, typically spectrophotometry. The concentration of formaldehyde is then quantified based on the color intensity of the resultant solution.
Method B: This method uses a direct titration technique to measure formaldehyde content. The textile sample is treated with hydrochloric acid to liberate formaldehyde gas, which is then absorbed in a sodium sulfite solution. The amount of formaldehyde is determined through the use of a standardized sodium hydroxide solution.
Compliance and regulations
EN ISO 14184:2011 is recognized and adopted by many countries around the world. Compliance with this standard is often a legal requirement for textile products sold in those jurisdictions. Textile manufacturers and retailers must ensure that their products undergo rigorous testing to meet the formaldehyde content specifications outlined in the standard. Independent third-party testing laboratories are often utilized to verify compliance.
