AATCC 112-2020 is applicable to textile fabrics that may release formaldehyde, particularly fabrics finished withchemicals containing formaldehyde. It provides accelerated storage conditions and an analytical means for determining the amount of formaldehyde released under the conditions of accelerated storage.
An optional accelerated incubation procedure is available.
A weighed fabric specimen is suspended over water in a sealed jar. The jar is placed in an oven at a controlled temperature for a specified length of time. The amount of formaldehyde absorbed by the water is then determinedcolorimetrically.
