(Main)Durability of wood and wood-based products - Quantitative determination of quaternary ammonium compounds in wood
Durability of wood and wood-based products - Quantitative determination of quaternary ammonium compounds in wood
This CEN Technical Report specifies a laboratory method of determining the content of quaternary ammonium compounds in commercially QAC-treated wood. The method described has a measurement range up to QAC contents of 1 500 mg/kg of dry matter.
NOTE 1 This method can need some modifications with some wood species such as hardwoods.
NOTE 2 It is applicable to QAC with a molar mass ranging between 200 g/mol and 500 g/mol.
NOTE 3 The method has a quantification limit corresponding to 250 mg of QAC per kilogram of wood expressed as dry matter.

Le présent Rapport technique CEN spécifie une méthode de laboratoire permettant de déterminer la teneur en composés d'ammonium quaternaire dans le bois traité avec des QAC, disponible dans le commerce. La méthode décrite permet de mesurer jusqu'à des teneurs en QAC de 1 500 mg/kg de matière sèche.
NOTE 1 Des modifications peuvent être apportées à cette méthode en fonction de l'essence de bois comme les bois feuillus.
NOTE 2 Elle s'applique aux QAC dont la masse molaire est comprise entre 200 g/mol et 500 g/mol.
NOTE 3 Cette méthode a une limite de quantification correspondant à 250 mg de QAC par kilogramme de bois exprimé en matière sèche.
