Respiratory infection prevention devices for self- and third-party protection - Part 2: Test methods
This document specifies the test methods for respiratory infection prevention devices (RIPDs).
RIPDs are intended to reduce the emission of infective agents from the user’s airways into the environment, and also reduce exposure to the user from inhalation of infective agents.
RIPDs are intended for use by everybody regardless of facial morphology or ability.
Atemwegsinfektionsschutzgeräte für den Selbst- und Fremdschutz - Teil 2: Prüfverfahren
Dieses Dokument legt die Prüfverfahren für Atemwegsinfektionsschutzgeräte (RIPDs) fest.
RIPDs dienen dazu, die Absonderung von infektiösen Keimen aus den Atemwegen des Anwenders in die Umgebung zu verringern und die Exposition des Anwenders durch das Einatmen infektiöser Keime zu reduzieren.
RIPDs sind für die Verwendung durch alle Personen unabhängig von ihrer Gesichtsmorphologie oder ihren Fähigkeiten vorgesehen.
Dispositifs de prévention des infections respiratoires pour la protection individuelle et de tiers - Partie 2 : Méthodes d’essai
Le présent document spécifie les méthodes d’essai pour les dispositifs de prévention des infections respiratoires (DPIR).
Les DPIR sont destinés à réduire l’émission d’agents infectieux des voies respiratoires de l’utilisateur dans l’environnement, et aussi à réduire l’exposition de l’utilisateur à l’inhalation d’agents infectieux.
Les DPIR sont destinés à être utilisés par tout le monde, indépendamment de la morphologie faciale ou de la capacité.

European foreword
This document (prEN 18178-2:2025) has been prepared by Technical Committee CEN/TC 205 “Non-
active medical devices”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
The EN 18178 series consists of the following parts, under the general title Respiratory infection
prevention devices for self- and third-party protection:
— Part 1: Requirements and markings
— Part 2: Test methods
— Part 3: Sustainability, human factors and rationales
— Part 4: Selection and use
— Part 5: Classification
Introduction
During outbreaks of respiratory infection, a device that protects in both directions of breathing (outward
and inward) may be required. In environments subject to the Medical Device (MD) Regulation (EU)
2017/745, the standard EN 14683 applies. In environments subject to the Personal Protective Equipment
(PPE) Regulation (EU) 2016/425, there is a range of applicable standards (e.g. EN 149). In environments
where these EU Regulations are not applicable, the General Product Safety Directive (2001/95/EC)
(GPSD) applies, supported by CEN/TS 17553.
This document is intended to supplement prEN 18178-1:2025 for respiratory infection prevention
devices (RIPD).
The test methods are specified for complete systems or parts of devices.
The test methods listed are used to assess the requirements specified in prEN 18178-1:2025.
Specifications for the conduct of the test methods specified in this document are given in the
prEN 18178-1:2025.
NOTE Only Part 1 of this series of standards has been prepared under Standardization Request M/575.
1 Scope
This document specifies the test methods for respiratory infection prevention devices (RIPDs).
RIPDs are intended to reduce the emission of infective agents from the user’s airways into the
environment, and also reduce exposure to the user from inhalation of infective agents.
RIPDs are intended for use by everybody regardless of facial morphology or ability.
