WARNING — This part of ISO 14184 calls for the use of substances and/or procedures that may be
injurious to health if adequate precautions are not taken. It refers only to technical suitability and does
not absolve the user from legal obligations relating to health and safety at any stage. It has been
assumed in the drafting of this part of ISO 14184 that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
This part of ISO 14184 specifies a method for determining the amount of free formaldehyde and formaldehyde
extracted partly through hydrolysis by means of a water extraction method. The method can be applied to the
testing of textile samples in any form.
The procedure is intended for use in the range of free and hydrolysed formaldehyde on the fabric between
16 mg/kg and 3 500 mg/kg when determined by this method. The lower limit is 16 mg/kg. Below this limit, the
result is reported as “not detectable”.
A method for determination of released formaldehyde is given in ISO 14184-2.
