Foreword
This document (EN 1827:1999+A1:2009) has been prepared by Technical Committee CEN/TC 79 "Respiratory protective devices", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2009, and conflicting national standards shall be withdrawn at the latest by December 2009.
This European Standard supersedes EN 1827:1999.
This document includes Amendment 1, approved by CEN on 2009-05-01.
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specification which may be a complete standard or part of a standard, and practical performance tests have been carried out successfully on complete apparatus where specified in the appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characteristics and weight distribution are similar to those of the complete apparatus.
Scope
This European Standard specifies performance requirements, test methods and marking requirements for half masks (re-usable) without inhalation valves and with separable filters (designed for a maximum of single shift use) to protect against gases or gases and particles or particles only. It does not cover devices designed for use in circumstances where there is or might be an oxygen deficiency (oxygen less than 17 % by volume) or for escape purposes. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.

Terms and definitions
For the purposes of this European Standard the definitions in EN 132 and the nomenclature from EN 134 apply.
Gas filters remove specified gases. Combined filters remove dispersed solid and/or liquid particles and specified gases. The term "gases" is taken to include vapours.
Particle filters remove solid and/or liquid particles.
A solid aerosol is defined as a dispersion of solid particles in air. A liquid aerosol is defined as a dispersion of liquid particles in air.
Description
A half mask without inhalation valves covers the nose and mouth and the chin, has no inhalation valves and may or may not have exhalation valves. It comprises a facepiece and separable and replaceable filters. It provides adequate sealing for the intended use on the face of the wearer against the ambient atmosphere, when the skin is dry or moist and when the head is moved.
Inhalation air enters through the filter and passes directly to the nose and mouth area of the device. Exhaled air passes through the filter and an exhalation valve (if fitted) to the ambient atmosphere.
In addition to providing protection against gases these devices can be designed to protect against both solid and liquid aerosols.
Classification
5.1
General
Half masks shall be classified according to the types and classes of filters used.
5.2
Filter types
Type FM A - for use against certain organic gases and vapours with a boiling point higher than 65 °C as specified by the manufacturer.
Type FM B - for use against certain inorganic gases and vapours as specified by the manufacturer (excluding carbon monoxide).
Type FM E - for use against sulfur dioxide and other acid gases and vapours as specified by the manufacturer.
Type FM K - for use against ammonia and organic ammonia derivatives as specified by the manufacturer.
6 Type FM AX - for use against certain low boiling organic compounds as specified by the manufacturer.
Type FM SX - for use against specific named gases and vapours.
!Type FM P NR - for single shift use against particles."
Any combination of these types is permitted.
5.3
Filter classes
5.3.1 Gas filter classes
Class 1 - low capacity (Gas 1).
Class 2 - medium capacity (Gas 2).
The protection provided by class 2 devices includes that provided by the corresponding class 1 device of the same type.
FM AX and FM SX filters are not classified.
5.3.2 Particle filter classes
!Class 1 low filtering efficiency (FM P1 NR).
Class 2 medium filtering efficiency (FM P2 NR).
Class 3 high filtering efficiency (FM P3 NR).
The protection provided by a FM P2 NR - or FM P3 NR - filter also includes that provided by the corresponding filter of lower class or classes."
Designation
Respiratory protective devices meeting the requirements of this European Standard shall be designated as follows:
!Half mask without inhalation valve EN 1827, year of publication, type, classification, option (where "D" is an option for a non re-useable half mask without inhalation valves and mandatory for a re-useable half mask without inhalation valves).
