Leather - Chemical determination of N-methyl-2-pyrrolidone (NMP) in leather (ISO 19070:2016)

This International Standard specifies a method to determine the amount of N-methyl-2-pyrrolidone
(NMP) in leather and leather components.
This method may also be used for the determination of N-ethyl-2-pyrrolidone (NEP) in leather.

Leder - Chemische Bestimmung von N-methyl-2-pyrrolidon (NMP) in Leder (ISO 19070:2016)

Diese Internationale Norm legt ein Verfahren zur Bestimmung des Gehalts an N-Methyl-2-pyrrolidon (NMP) in Leder und Lederbestandteilen fest.
Dieses Verfahren kann auch zur Bestimmung von N-Ethyl-2-pyrrolidon (NEP) in Leder angewendet werden.

Cuir - Détermination de la teneur en N-méthylpyrrolidone (NMP) dans le cuir (ISO 19070:2016)

ISO 19070:2016 spécifie une méthode de détermination de la teneur en N-méthyl-2-pyrrolidone (NMP) dans le cuir et les composants en cuir.
Cette méthode peut également être utilisée pour déterminer la teneur en N-éthyl-2-pyrrolidone (NEP) dans le cuir.

Usnje - Kemijsko določevanje N-metil-2-pirolidona (NMP) v usnju (ISO 19070:2016)

Ta mednarodni standard določa metodo za določevanje količine N-metil-2-pirolidona
(NMP) v usnju in delih iz usnja. Ta metoda se lahko uporablja tudi za določanje N-etil-2-pirolidona (NEP) v usnju.
