EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 14184-2 testing. ISO 14184-2 specifies a method for determining the amount of formaldehyde released from textiles in any form under accelerated storage conditions by a vapor absorption method.

The procedure is designed for use in the range of releasable formaldehyde on fabric between 20 mg/kg and 3.500 mg/kg when determined by this method. The lower limit is 20 mg/kg. Below this limit, the result is reported as "not detectable".
A method for the determination of free formaldehyde and formaldehyde extracted by partial hydrolysis in aqueous solution is given in ISO 14184-1:2011.
A weighed fabric sample is suspended on water in a sealed jar. The jar is placed in an incubator at a controlled temperature for a specified period of time. The amount of formaldehyde absorbed by the water is then determined colorimetrically.
Dissolve 150 g of ammonium acetate in approximately 800 ml of water, add 3 ml of glacial acetic acid and 2 ml of acetylacetone, transfer to a 1000 ml measuring flask and make up to the mark with water. Store in a brown bottle.
The color of the reagent darkens slightly when left for over the first 12 hours. Therefore, the reagent should be left for 12 hours before use. Otherwise, the reagent can be used for a substantial period of time, at least 6 weeks. However, it is good practice to run a weekly calibration curve to correct for minor changes in the standard curve, as precision may vary slightly over a long period of time.
