Fabric Formaldehyde Content Tester
ASTM D600 Formaldehyde Climate TesterIntroduction
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.
Aatcc 112 Textile Formaldehyde Content TesterApplication
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.
