Determination of material resistance to permeation by chemicals - Part 1: Permeation by liquid chemical under conditions of continuous contact
This European Standard specifies a test method for the determination of the resistance of protective clothing, gloves and footwear materials to permeation by potential hazardous liquid chemicals under the condition of continuous contact.
This test method is applicable to the assessment of protection against liquid chemicals that can be collected only by liquid or gaseous collecting media.
This test method is not adapted for the assessment of chemical mixtures, except for aqueous solutions.
This standard shall be used with the specifications given in the products standards (for examples EN 374 1 for gloves) where the following information shall be defined:
- any pre-conditioning;
- precise sampling (place, size, number);
- associated levels of performance.
Bestimmung des Widerstands von Materialien gegen die Permeation von Chemikalien - Teil 1: Permeation durch eine flüssige Chemikalie unter Dauerkontakt
Diese Europäische Norm legt ein Prüfverfahren für die Bestimmung des Widerstands von Schutzkleidungsmaterial, Schutzhandschuh- und Fußschutzmaterial gegen die Permeation von möglicherweise gefahrbringenden flüssigen chemischen Stoffen bei Dauerkontakt fest.
Dieses Prüfverfahren gilt für die Beurteilung des Schutzes gegen flüssige chemische Stoffe, die nur mit flüssigen oder gasförmigen Sammelmedien erfasst werden können.
Dieses Prüfverfahren eignet sich nicht für die Beurteilung von chemischen Gemischen, ausgenommen sind wässrige Lösungen.
Diese Norm ist gemeinsam mit den in den Produktnormen angegebenen Festlegungen zu verwenden (z. B. EN 374-1 für Schutzhandschuhe), wo die folgenden Informationen festgelegt sind:
jegliche Vorbehandlung;
genaue Probenahme (Ort, Größe, Anzahl);
zugeordnete Leistungsstufen.
Détermination de la résistance des matériaux à la perméation par des produits chimiques - Partie 1 : Perméation par un produit chimique liquide dans des conditions de contact continu
La présente Norme européenne spécifie une méthode d'essai pour la détermination de la résistance des matériaux utilisés dans la confection de vêtements de protection, gants et chaussures à la perméation par des produits chimiques liquides potentiellement dangereux, dans des conditions de contact continu.
La présente méthode d'essai s'applique à l'évaluation de la protection contre les produits chimiques liquides qui ne peuvent être collectés qu'au moyen d'un milieu collecteur liquide ou gazeux.
La présente méthode d'essai n'est pas adaptée à l'évaluation de mélanges de produits chimiques, à l'exception des solutions aqueuses.
La présente norme est utilisée avec les spécifications fournies dans les normes de produits (par exemple, l'EN 374 1 pour les gants), dans lesquelles les informations suivantes sont définies :
tout préconditionnement ;
un échantillonnage précis (endroit, taille, nombre) ;
les niveaux de performance correspondants.

This method provides tests results in terms of breakthrough time. This parameter is a key measure of the effectiveness of a material to act as a barrier to the challenge chemical. Such information is used in the comparison of the performances of PPE materials during the process of selecting PPE for protection from hazardous chemicals. Long breakthrough times are characteristic of high permeation resistance. Breakthrough time does not provide a correlation between protection and the toxicity of the chemicals tested, only cumulative permeation can provide this information. It has been assumed in the drafting of this part of EN 16523 that the execution of its provisions will be entrusted to appropriately qualified and experienced people with a sound understanding of analytical chemistry. Appropriate precautions should be taken when carrying out this type of testing in order to avoid injury to health and contamination of the environment. A future part of EN 16523 will explain the use of the series of standards EN 16523. SIST EN 16523-1:2015
