Overview

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 shall be reported as "not detectable". A method for determination of released formaldehyde is given in ISO 14184-2. 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. Formaldehyde is extracted from a textile sample with water at 40 °C. The amount of formaldehyde is then determined colorimetrically. This document (EN ISO 14184-1:2011) has been prepared by Technical Committee CEN/TC 248 "Textile and textile products", the secretariat of which is held by BSI (United Kingdom). The responsible German committee is Working Committee NA 062-05-12 AA "Textilchemische Prüfverfahren und Fasertrennung" ("Testing methods for separation and chemistry of textile fibres") of the Materials Testing Standards Committee (NMP) at DIN. The following modifications have been made with respect to DIN EN ISO 14184-1:1999-02: a) the standard has been editorially revised.
