This British Standard describes two methods for determining formaldehyde on textiles: “total formaldehyde?? and “free and water-soluble formaldehyde?? using chromotropic acid and sulfuric acid for detection and quantification. The methods may be applied to any textile product containing a formaldehyde-based precursor.
The methods are not compatible with and cannot be compared directly with BS EN ISO 14184-1 and BS EN ISO 14184-2.
