Protective clothing - Protection against liquid chemicals - Test method: Resistance of materials to penetration by liquids
This European Standard is concerned with the application of the described method of test, usually with chemicals of low volatility. Clothing made of these materials is not for use as the sole means of protection where resistance to permeation by chemicals at the molecular level (see EN 369) is essential and where a complete barrier to liquid (or gaseous chemicals) is required (e.g. risk of exposure to massive and forceful discharges of concentrated liquid chemicals). Clothing which has been developed from materials selected by this method of test should be used therefore only in well-defined circumstances when an evaluation of the finished item has indicated an acceptable level of performance (e.g. in laboratory and field testing of a garment, consideration of exposure levels to specified chemicals etc.). Two levels of the potential performance of materials are assessed by the method of test to meet with possible requirements for protection against: a) deposition on the surface of a material, at minimal pressure, of spray droplets up to coalescence or occasional small drips; b) contamination by a single copious splash or low pressure jet, allowing sufficient time to divest the clothing or take other action as necessary to eliminate any hazard to the wearer from chemical retained by the protective garment, or, in circumstances where pressure is applied to liquid contaminants on the surface of the clothing material as a result of natural movements of the wearer (flexing of contaminated areas of clothing at arms, knees, shoulders) and contact with contaminated surfaces (e.g. walking through sprayed foliage).

Die Norm EN 368:1992 bietet einen klaren Rahmen für den Test von Schutzkleidung gegen flüssige Chemikalien. Der Fokus liegt auf der Widerstandsfähigkeit der Materialien gegenüber der Penetration von Flüssigkeiten, insbesondere bei Chemikalien mit niedriger Volatilität. Der Geltungsbereich dieser Norm ist entscheidend, da sie explizit darauf hinweist, dass die geprüfte Kleidung nicht als alleinige Schutzmaßnahme verwendet werden sollte, wenn es um den chemischen Durchgang auf molekularer Ebene geht. Diese Klarstellung ist besonders für Anwender in risikobehafteten Umgebungen von Bedeutung, wo ein vollständiger Barriereschutz gegen chemische Gefahren erforderlich ist. Zu den Stärken der EN 368:1992 gehört die detaillierte Bewertung der Materialleistung in zwei verschiedenen Szenarien. Zum einen wird die Fähigkeit eines Materials getestet, Spritztröpfchen bei minimalem Druck zu widerstehen, was für den Schutz gegen geringfügige chemische Expositionen wichtig ist. Zum anderen wird die Resistenz gegen eine einmalige, ausgiebige Spritzung oder einen Niederdruckstrahl überprüft, was in Situationen von Bedeutung ist, in denen der Träger Zeit hat, geeignete Maßnahmen zu ergreifen, um mögliche Gefahren zu beseitigen. Diese zweistufige Leistungsbewertung gewährleistet, dass nur Kleidung, die in spezifischen Tests als sicher identifiziert wurde, in bestimmten, klar definierten Situationen eingesetzt wird. Die Relevanz der Norm liegt in ihrer Fähigkeit, ein akzeptables Leistungsniveau für schützende Kleidung zu garantieren. Dies ist besonders wichtig in Labor- und Einsatzbedingungen, wo eine präzise Bewertung der Expositionslevels gegenüber festgelegten Chemikalien erfolgt. Die Norm trägt somit dazu bei, das Risiko für die Träger zu minimieren und einen hohen Standard in der Herstellung und Anwendung von Schutzausrüstungen zu gewährleisten. Zusammenfassend lässt sich sagen, dass die EN 368:1992 eine essentielle Ressource für die Entwicklung und den Einsatz von Schutzkleidung darstellt, die gegen flüssige Chemikalien schützt. Ihre detaillierten Vorgaben zur Prüfung und Anwendung von Materialien machen sie unverzichtbar für Fachleute, die sicherstellen müssen, dass ihre Produkte den hohen Anforderungen an Sicherheit und Leistung gerecht werden.
La norme EN 368:1992, intitulée "Vêtements de protection - Protection contre les produits chimiques liquides - Méthode d'essai : Résistance des matériaux à la pénétration par les liquides", se situe dans un cadre essentiel pour la sécurité des équipements de protection individuelle. Son champ d'application, bien défini, se concentre sur l'évaluation des matériaux exposés à des produits chimiques de faible volatilité, apportant ainsi une réponse pertinente aux besoins spécifiques du secteur. Parmi les forces de cette norme, on notable l'établissement de deux niveaux de performance potentielle des matériaux, permettant d'évaluer efficacement leur résistance. La méthode d'essai évaluée prend en compte des situations variées, qu'il s'agisse de dépôts de gouttes de spray à faible pression ou d'expositions à des éclaboussures abondantes. Cette capacité à tester des scénarios pratiques permet une meilleure adéquation entre le vêtement de protection et les risques potentiels rencontrés par les utilisateurs. La pertinence de la norme EN 368:1992 est accentuée par son rappel qu'elle ne doit pas être considérée comme une solution isolée mais plutôt comme une partie d'un ensemble de mesures de protection. Ainsi, elle précise que les vêtements fabriqués à partir de matériaux conformes à cette norme doivent être utilisés dans des circonstances spécifiques, toujours en association avec d'autres moyens de protection quand une barrière complète contre la pénétration chimique est cruciale. En résumé, la norme EN 368:1992 non seulement établit des critères de performance clairs pour la résistance à la pénétration de liquides, mais elle guide également les utilisateurs dans la sélection appropriée de vêtements de protection pour des situations de travail particulières, renforçant ainsi la sécurité dans l'utilisation des produits chimiques.
EN 368:1992 is a significant European Standard that outlines a test method for evaluating the resistance of protective clothing materials against penetration by liquid chemicals. The standard primarily focuses on clothing intended for use with low volatility chemicals, establishing a clear scope for its application. One of the key strengths of this standard is its rigorous assessment of fabric performance under specific conditions, particularly in scenarios involving minimal pressure, which is crucial for ensuring the safety and effectiveness of protective garments. The standard delineates two distinct levels of protection that are evaluated through testing, enhancing its relevance in practical applications. The first level addresses the deposition of spray droplets on the fabric surface, ensuring that the protective clothing can withstand minor exposure without suffering penetration. The second level concerns itself with more substantial threats, such as single large splashes or low-pressure jets, which require timely removal of the garment to mitigate potential hazards. This dual-level assessment not only demonstrates comprehensive protection criteria but also informs users when specific garments are to be worn relative to the expected exposure. Another notable aspect is that EN 368:1992 emphasizes the necessity of evaluating the finished protective clothing item in a real-world context, including laboratory and field testing. This consideration for actual usage scenarios ensures that the clothing developed from materials meeting this standard performs reliably under conditions that may not be strictly controlled. The adaptability of this standard to various operational demands reinforces its importance within industries that may be exposed to liquid chemical hazards. Additionally, the standard serves as a critical reference point for manufacturers and safety professionals, guiding the design and use of protective clothing. It is essential to recognize that while EN 368:1992 provides useful protection against certain liquid chemicals, it is not intended as the sole means of defense against all forms of chemical permeation, particularly against gaseous chemicals or high levels of exposure. This delineation is crucial for appropriate risk management in any working environment that involves exposure to hazardous materials. In summary, EN 368:1992 stands out as an essential standard for protective clothing against liquid chemicals, providing a structured methodology for testing material performance while ensuring user safety through its comprehensive assessment criteria and practical guidelines. Its focus on empirical evaluation and real-world applicability makes it a relevant and valuable resource for professionals in sectors dealing with chemical exposures.
この標準文書SIST EN 368:1996は、液体化学物質に対する保護衣類の試験方法を定義しており、特に低揮発性の化学物質に対する素材の浸透抵抗の評価に重点を置いています。この標準は、化学物質の分子レベルでの浸透抵抗が必須である場合や、液体または気体の化学物質に対して完全なバリアが求められる場合には、単独の保護手段としては使用されないことが明確に示されています。 この基準の強みは、衣類が特定の条件下でどのように機能するかを定量的に評価できる点にあります。衣類の性能評価には、材料の表面における最小圧力下でのスプレー滴の堆積や、単一の大量跳ね返りによる汚染の影響を考慮しており、実際のテスト環境において使用される可能性のある条件を反映しています。これにより、使用する素材が明確に定義された状況下でのみ適切であることが強調されており、保護されるべき化学物質に対する具体的な評価が可能となります。 また、衣類の性能を二段階で評価することができるため、さまざまなリスク条件に適応することができます。たとえば、衣類の表面に付着する微小な滴や、比較的低圧の洗浄による汚染を考慮しており、これにより使用者が必要に応じて迅速に衣類を脱いだり、他の対策を講じることができるような、実践的なアプローチを提供しています。 この標準は、研究室やフィールドテストにおける衣類の評価を通じて、特定の化学物質に対する暴露レベルの考慮も促進しており、使用者の安全を高めるための重要なガイドラインとなっています。そのため、EN 368:1992は、保護衣類の設計と製造において、特に液体化学物質に対する耐性を求める現場での関連性が非常に高いと言えるでしょう。
