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 document is not applicable to face masks intended exclusively for the personal protection of staff.
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 darüber hinaus hinsichtlich der Verringerung von Absonderungen infektiöser Keime aus Mund und Nase eines asymptomatischen Trägers oder eines Patienten mit klinischen Symptomen wirksam sein.
Dieses Dokument gilt nicht für Gesichtsmasken, die ausschließlich für den persönlichen Schutz des Personals bestimmt sind.
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.
Le présent document ne s’applique pas aux masques exclusivement destinés à la protection individuelle des membres de l’équipe médicale.
