Textile formaldehyde content tester
BACK
Standards:
Applications:
Textile formaldehyde content tester is used to determinate the formaldehyde content in the various textiles, clothing fabrics, often using water extraction method to prepare formaldehyde solution, and then after the color reaction with the Nessler reagent, the software can be tested out the formaldehyde content in textiles.
Product Information:
In China, the national mandatory standard "national textile products basic safety technical specifications" GB18401-2003. with effect from 1 January 2006 to enforcement, clearly defined the safety requirements of formaldehyde and other harmful substances in textile products. January 1. 2010 from the implementation of a number of national standards for clothing and textiles: "woven student service" GB / T23328-2009. "male suit, coat" GB / T2664-2009. "female suit, coat" GB / T2665- 2009. "trousers" GB / T2666-2009. "tie" GB / T23314-2009. etc., also clearly put forward the restrictions of the formaldehyde content.
Standards:
1. GB/T2912 Textiles - Determination of formaldehyde - Part 1: Free and hydrolyzed formaldehyde
2. AATCC 112 Textiles - Determination of formaldehyde - Vapor absorption method
3. BS6806 Textile formaldehyde testing
4. DIN EN ISO14184.2 Textiles-Determination of formaldehyde-Part2: Released formaldehyde (vapor absorption method)
