Introduction
Industrial organic solvents are often used as ingredients of adhesive, treating agents and coating agents for
footwear.
Some organic solvents are toxic. Harmful solvents left in footwear materials can penetrate into the human
body through skin contact during wearing and by inhalation after being released from the footwear,
harming the health of consumers. Both glycol ethers and amide solvents will form highly toxic compounds
after metabolism in the body, which cause permanent damage to the blood and nervous system. Long-term
exposure to high concentrations of these compounds can cause cancer. In addition, ethylene glycol ether
solvents can cause permanent damage to the female reproductive system.
Due to this potential effect, the listed organic solvents in Annex A are based on those which have been
[1]
restricted in some regulations (e.g. by the EU regulation No 1907/2006 in the European Union, and by
the U.S. Environmental Protection Agency). ISO/TR 16178 describes which materials are concerned by this
determination.

L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux
de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.

Introduction
Les solvants organiques industriels sont souvent utilisés dans la composition des colles, des agents de
traitement et des agents de revêtement pour les chaussures.
Certains solvants organiques sont toxiques. Les solvants dangereux présents dans les matériaux de
chaussures peuvent pénétrer dans le corps humain par contact avec la peau au porter et par inhalation
après avoir été libérés par la chaussure, ce qui est néfaste pour la santé des consommateurs. Les solvants
d’éthers de glycol et les solvants d’amides vont former des composés hautement toxiques après avoir été
métabolisés dans le corps, causant des dommages permanents sur la circulation sanguine et le système
nerveux. Une exposition à long terme à de fortes concentrations de ces composés peut causer un cancer. En
outre, les solvants à base d’éther d’éthylène-glycol peuvent causer des dommages permanents au système
reproducteur féminin.
En raison de cet effet potentiel, les solvants organiques énumérés dans l’Annexe A sont basés sur ceux qui
[1]
ont fait l’objet de restrictions dans certaines réglementations (par exemple le Règlement UE 1907/2006
au sein de l’Union européenne et l’Agence de protection de l’environnement des États-Unis). L’ISO/TR 16178
décrit les matériaux qui sont concernés par ce dosage.

Le présent document spécifie une méthode pour la quantification des résidus de certains solvants organiques
(voir l’Annexe A) dans les matériaux des chaussures par chromatographie en phase gazeuse couplée à la
spectrométrie de masse (GC-MS).
Le présent document est applicable aux matériaux des chaussures susceptibles de contenir certains
résidus de solvant (par exemple solvant présent dans les colles, la finition du cuir et les textiles enduits, les
plastiques, le caoutchouc).
