Textiles - Determination of formaldehyde - Part 1: Free and hydrolised formaldehyde (water extraction method) (ISO 14184-1:2011)

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.

Textilien - Bestimmung des Gehaltes an Formaldehyd - Teil 1: Freier und hydrolisierter Formaldehyd (Wasser-Extraktions-Verfahren) (ISO 14184-1:2011)

Dieser Teil von ISO 14184 legt ein Verfahren zur Bestimmung des Gehaltes von freiem Formaldehyd und von Formaldehyd fest, der teilweise durch Hydrolyse mithilfe eines Wasser Extraktionsverfahrens extrahiert wurde. Das Verfahren kann zur Prüfung von Textilproben jeder Art angewandt werden.
Der Ablauf ist zur Bestimmung des freien und hydrolysierten Formaldehyds auf dem Flächengebilde im Bereich von 16 mg/kg bis 3 500 mg/kg unter Anwendung dieses Verfahrens vorgesehen. Der untere Grenzwert beträgt 16 mg/kg. Ergebnisse unter diesem Grenzwert sind als "nicht nachweisbar" anzugeben.
Ein Verfahren zur Bestimmung des freigesetzten Formaldehyds wird in ISO 14184 2 angegeben.

Textiles - Dosage du formaldéhyde - Partie 1: Formaldéhyde libre et hydrolysé (méthode par extraction d'eau) (ISO 14184-1:2011)

L'ISO 14184-1:2011 spécifie une méthode pour déterminer la quantité de formaldéhyde libre et de formaldéhyde extrait partiellement par hydrolyse selon une méthode d'extraction d'eau. La méthode peut être appliquée aux essais d'échantillons textiles quelle que soit leur forme.
Le mode opératoire est destiné à être utilisé pour déterminer les teneurs d'une étoffe en formaldéhyde libre et hydrolysé comprises entre 16 mg/kg et 3500 mg/kg. En deçà de la limite inférieure de 16 mg/kg, le résultat est rapporté comme «non détectable».
L'ISO 14184-2 donne une méthode de détermination du formaldéhyde dégagé.

Tekstilije - Določevanje formaldehida - 1. del: Prosti in hidrolizirani formaldehid (vodna ekstrakcija) (ISO 14184-1:2011)

Ta del ISO 14184 določa metodo za določevanje količine prostega formaldehida in formaldehida, delno ekstrahiranega s hidrolizo z uporabo vodne ekstrakcije. Ta metoda se lahko uporablja pri preskušanju vzorcev tekstila vseh oblik. Postopek je namenjen uporabi v razponu prostega in hidroliziranega formaldehida na tkanini med 16 mg/kg in 3500 mg/kg, kadar se določa s to metodo. Spodnja meja je 16 mg/kg. Pod to mejo je rezultat »nezaznaven«. Metoda za določanje sproščenega formaldehida je podana v ISO 14184-2.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14184-1 was prepared by Technical Committee ISO/TC 38, Textiles.
This second edition cancels and replaces the first edition (ISO 14184-1:1998), of which it constitutes a minor
revision.
ISO 14184 consists of the following parts, under the general title Textiles — Determination of formaldehyde:
⎯ Part 1: Free and hydrolysed formaldehyde (water extraction method)
⎯ Part 2: Released formaldehyde (vapour absorption method)

Textiles — Determination of formaldehyde —
Part 1:
Free and hydrolysed formaldehyde (water extraction method)
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.
1 Scope
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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 3696:1987, Water for analytical laboratory use — Specification and test methods
ISO 4793:1980, Laboratory sintered (fritted) filters — Porosity grading, classification and designation
3 Principle
Formaldehyde is extracted from a textile sample with water at 40 °C. The amount of formaldehyde is then
determined colorimetrically.
4 Reagents
All reagents shall be of analytical reagent quality.
4.1 Distilled water or grade 3 water complying with ISO 3696.

4.2 Acetylacetone reagent (Nash reagent).
Dissolve 150 g of ammonium acetate in about 800 ml of water (4.1), add 3 ml of glacial acetic acid and 2 ml of
acetylacetone, transfer into a 1 000 ml volumetric flask and make up to the mark with water (4.1). Store in a
brown bottle.
The reagent darkens in colour slightly on standing over the first 12 h. For this reason, the reagent should be
held for 12 h before use. Otherwise, the reagent is usable over a considerable period of time, at least 6 weeks.
Since the sensitivity may change slightly over a long period of time, it is good practice to run a calibration
curve weekly to correct for slight changes in the standard curve.
4.3 Formaldehyde solution, approximately 37 % (M/V or M/m).
4.4 Ethanolic solution of dimedone.
Prepare by dissolving 1 g of dimedone (dimethyl-dihydro resorcinol or 5,5-dimethyl-cyclohexanedione) in
ethano
