Protective clothing - Protection against chemicals - Measurement of cumulative permeation of chemicals with low vapour pressure through materials (ISO 19918:2017)
ISO 19918 describes laboratory test methods to determine the resistance of materials, closures, and seams used in personal protective equipment (PPE) to permeation by solid or liquid chemicals with low vapour pressure (less than 133,322 Pa at 25 °C) and/or insolubility in water or other liquids commonly used as collection media. These chemicals that are often part of pesticide formulations and other mixtures cannot be measured using other standards for measuring permeation. This test method is suitable for field strength and concentrated pesticide formulations as well as other mixtures in which the active ingredient is a chemical with low vapour pressure and/or low solubility in commonly used liquid and gaseous collection media.
This test method is not intended to be used in place of standards such as ISO 6529, EN 16523-1 and ASTM F739, which measure permeation of chemicals that are either volatile or soluble in water or other liquids that do not interact with the material being tested. ISO 19918 is not suitable for measurement of volatile chemicals that may evaporate before the chemical analysis is complete.
The degree of contamination depends on numerous factors, such as type of exposure, application technique, and chemical formulation. As the level of exposure can vary considerably, this method is designed to rate relative performance of PPE materials for different durations.
This method is designed to measure cumulative permeation. Breakthrough time cannot be measured by this method. This test method does not measure resistance to penetration or degradation.
The test method standard may be used for the evaluation of PPE materials that are new or those for which the product standard requires treatment, such as laundering or simulated abrasion. Details of the treatment shall be reported.
Schutzkleidung - Schutz gegen Chemikalien - Messung der kumulativen Permeation von Chemikalien mit niedrigem Dampfdruck durch Materialien (ISO 19918:2017)
Dieses Dokument beschreibt Prüfverfahren im Labor zur Bestimmung des Widerstands von in persönlicher Schutzausrüstung (PSA) verwendeten Materialien, Verschlüssen und Nähten gegen Permeation fester oder flüssiger Chemikalien mit geringem Dampfdruck (weniger als 133,322 Pa bei 25 °C) und/oder nicht in Wasser oder anderen Flüssigkeiten löslicher Stoffe, die üblicherweise als Sammelmedien verwendet werden. Diese Chemikalien, die häufig in Pestizid-Rezepturen und anderen Gemischen vorkommen, können nicht mittels anderer Normen zur Messung der Permeation gemessen werden. Dieses Prüfverfahren ist geeignet für auf Anwendungsstärke verdünnte und für konzentrierte Pestizid-Rezepturen sowie andere Gemische, bei denen der aktive Inhaltsstoff eine Chemikalie mit geringem Dampfdruck und/oder geringer Löslichkeit in häufig verwendeten flüssigen und gasförmigen Sammelmedien ist.
Dieses Prüfverfahren soll nicht an Stelle von Normen, wie der ISO 6529, EN 16523 1 und ASTM F739, welche flüssige und gasförmige Sammelmedien verwenden, angewendet werden. ISO 19918 ist nicht geeignet zur Messung flüchtiger Chemikalien, welche verdampfen können, bevor die chemische Analyse abgeschlossen ist.
Der Kontaminationsgrad hängt von mehreren Faktoren ab, zum Beispiel der Expositionsart, der Anwendungstechnik und der chemischen Rezeptur. Da das Expositionsniveau erheblich variieren kann, ist dieses Verfahren so aufgebaut, dass die relative Leistungsfähigkeit der PSA Materialien bei unterschiedlicher Dauer eingestuft wird.
Dieses Verfahren dient der Messung der kumulativen Permeation. Die Durchbruchszeit kann durch dieses Verfahren nicht gemessen werden. Dieses Prüfverfahren misst nicht den Widerstand gegen Penetration oder Degradation.
Die Norm für das Prüfverfahren kann zur Bewertung sowohl von neuen als auch von zum Beispiel durch Waschen oder simulierten Abrieb behandelten PSA-Materialien genutzt werden. Genaue Informationen zur Behandlung müssen in den Bericht aufgenommen werden.
Habillement de protection - Protection contre les produits chimiques - Mesure de la perméation cumulée à travers des matériaux des produits chimiques ayant une faible pression de vapeur (ISO 19918:2017)
L'ISO 19918 décrit les méthodes d'essai de laboratoire employées pour déterminer la capacité des matériaux, fermetures et coutures utilisés sur les équipements de protection individuelle (EPI) à résister à la perméation de produits chimiques solides ou liquides caractérisés par une faible pression de vapeur (inférieure à 133,322 Pa à 25° C) et/ou par une insolubilité dans l'eau ou dans d'autres liquides communément utilisés comme milieux collecteurs. Ces produits chimiques qui font souvent partie de formulations de pesticides et d'autres mélanges ne peuvent pas être mesurés à l'aide d'autres normes de mesure de la perméation. Cette méthode d'essai s'applique aux mesures d'intensité de champ et aux formulations de pesticides concentrées ainsi qu'aux autres mélanges dans lesquels la matière active est un produit chimique caractérisé par une faible pression de vapeur et/ou une faible solubilité dans les milieux collecteurs liquides et gazeux communément utilisés.
Cette méthode d'essai n'a pas vocation à se substituer aux normes ISO 6529 et EN 16523‑1 et au standard ASTM F739, qui mesurent la perméation des produits chimiques volatils ou solubles dans l'eau ou dans d'autres liquides qui ne présentent aucune interaction avec le matériau soumis à essai. L'ISO 19918 ne convient pas pour la mesure des produits chimiques volatils susceptibles de s'évaporer avant la fin de l'analyse chimique.
Le degré de contamination dépend de nombreux facteurs, tels que le type d'exposition, la technique d'application et la formulation de produit chimique. Dans la mesure où le niveau d'exposition peut varier considérablement, cette méthode a été élaborée dans le but de classer les performances relatives des matériaux d'EPI pour différentes durées.
Cette méthode vise à mesurer la perméation cumulée. Elle ne s'applique pas à la mesure du temps de passage. Cette méthode d'essai ne permet pas de mesurer la résistance à la pénétration ou à la dégradation.
Elle peut être utilisée pour évaluer les matériaux d'EPI neufs ou les matériaux d'EPI pour lesquels la norme de produit nécessite un traitement particulier (par exemple, blanchissage ou abrasion simulée). Les détails du traitement doivent être consignés.
Varovalna obleka - Varovanje pred kemikalijami - Merjenje kumulativnega pronicanja kemikalij z nizkim parnim tlakom skozi materiale (ISO 19918:2017)
Ta mednarodni standard opisuje laboratorijske preskusne metode za določanje odpornosti materialov in šivov, ki se uporabljajo za varovalne obleke, vključno z rokavicami, proti pronicanju tekočin z nizkim parnim tlakom (manj kot 1 mm Hg pri 25 °C) in/ali netopnostjo v vodi ali drugi tekočini, ki ne vpliva na material. Teh kemikalij, ki so pogosto del pesticidnih pripravkov in drugih zmesi, ni mogoče izmeriti z uporabo drugih standardov za merjenje pronicanja. Ta preskusna metoda je primerna za jakosti polja in koncentrirane pesticidne pripravke ter druge zmesi, pri katerih je aktivna sestavina kemikalija z nizkim parnim tlakom in/ali netopnostjo v vodi, ali druga tekočina, ki ne reagira z materialom obleke. Ta metoda morda ni primerna za preskušanje materialov varovalnih oblek proti hlapnim pesticidnim pripravkom. Stopnja kontaminacije je odvisna od številnih dejavnikov, kot so vrsta izpostavljenosti, tehnika uporabe in sestava pesticida. Ker se lahko raven izpostavljenosti močno razlikuje, je ta metoda zasnovana za oceno relativne učinkovitosti materialov osebne varovalne opreme pri različnem trajanju izpostavljenosti. Ta metoda je zasnovana za merjenje kumulativnega pronicanja. Časa, v katerem pride do pronicanja, ni mogoče izmeriti s to metodo. Ta preskusna metoda se ne uporablja za merjenje odpornosti proti pronicanju ali degradaciji. Standard preskusne metode je mogoče uporabiti za oceno novih materialov ali tistih, ki so bili obdelani, npr. oprani ali podvrženi simulirani obrabi. O podrobnostih obdelave je treba poročati. To preskusno metodo je mogoče uporabiti tudi za določanje odpornosti, ki jo varovalna obleka zagotavlja proti pronicanju kemikalij z nizkim parnim tlakom.
