Medical face masks - Requirements and test methods
This document specifies construction, design, performance requirements and test methods for medical face masks intended to limit the transmission of infective agents from staff to patients during surgical procedures and other medical settings with similar requirements. A medical face mask with an appropriate microbial barrier can also be effective in reducing the emission of infective agents from the nose and mouth of an asymptomatic carrier or a patient with clinical symptoms.
This European Standard is not applicable to masks intended exclusively for the personal protection of staff.
NOTE 1 Standards for masks for use as respiratory personal protective equipment are available.
NOTE 2 Annex A provides information for the users of medical face masks.
Medizinische Gesichtsmasken - Anforderungen und Prüfverfahren
Dieses Dokument legt Aufbau und Gestaltung, Leistungsanforderungen sowie Prüfverfahren für medizinische Gesichtsmasken fest, die dazu dienen, die Übertragung infektiöser Keime vom Personal auf Patienten während chirurgischer Eingriffe und sonstiger medizinischer Situationen mit ähnlichen Anforderungen zu begrenzen. Eine medizinische Gesichtsmaske mit einer geeigneten mikrobiologischen Barriere kann ebenso hinsichtlich der Verringerung von Absonderungen infektiöser Keime aus Mund und Nase eines asymptomatischen Trägers oder eines Patienten mit klinischen Symptomen wirksam sein.
Diese Europäische Norm gilt nicht für Masken, die ausschließlich für den persönlichen Schutz des Personals bestimmt sind.
ANMERKUNG 1 Normen für Masken zum Gebrauch als persönliche Atemschutzausrüstung stehen zur Verfügung.
ANMERKUNG 2 Anhang A stellt Informationen für die Benutzer medizinischer Gesichtsmasken zur Verfügung.
Masques à usage médical - Exigences et méthodes d'essai
Le présent document spécifie les exigences de fabrication, de conception et de performance, ainsi que les méthodes d’essai relatives aux masques à usage médical destinés à limiter la transmission d’agents infectieux des membres de l’équipe médicale aux patients lors d’actes chirurgicaux et d’autres actes médicaux aux exigences similaires. Un masque à usage médical présentant une barrière antimicrobienne appropriée peut également s’avérer efficace pour diminuer l’émission d’agents infectieux venant du nez et de la bouche d’un patient présentant des symptômes cliniques ou asymptomatique.
La présente Norme européenne ne s’applique pas aux masques exclusivement destinés à la protection individuelle des membres de l’équipe.
NOTE 1 Il existe des normes relatives aux masques destinés à la protection individuelle des voies respiratoires.
NOTE 2 L’Annexe A apporte des informations aux utilisateurs des masques à usage médical.
Medicinske maske za obraz - Zahteve in preskusne metode
Ta dokument določa zahteve glede izdelave, načrtovanja in učinkovitosti ter preskusne metode za medicinske maske za obraz, ki so namenjene omejevanju prenosa povzročiteljev infekcije z zaposlenih na bolnike med kirurškimi postopki in v drugih zdravstvenih okoljih s podobnimi zahtevami. Medicinska maska za obraz z ustrezno mikrobno pregrado je lahko učinkovita pri zmanjševanju razširjanja povzročiteljev infekcije iz nosa in ust asimptomatskega prenašalca ali bolnika s kliničnimi znaki.
Ta evropski standard se ne uporablja za maske, ki so namenjene izključno osebni zaščiti zaposlenih.
OPOMBA 1: Na voljo so standardi za maske, ki se uporabljajo za osebno varovalno opremo.
OPOMBA 2: V dodatku A so podane informacije za uporabnike medicinskih mask za obraz.
