CEN/TC 79/SC 4 - Filters and absorption devices

This European Standard refers to filtering devices with a hood for personal escape from particulate matter, carbon monoxide and other toxic gases produced by fire. It specifies minimum requirements for this device which is for single use. 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).
Two types of devices are specified; namely, those designed to be carried on the person and those designed to be stored.
This standard specifies devices primarily designed for adult users. Some devices may not be suitable for children.
Laboratory and practical performance tests are included for the assessment of compliance with the requirements.

This European Standard applies to filters with breathing hoses (non-mask mounted filters) for use as components in unassisted respiratory protective devices to be worn by the wearer, with the exception of escape apparatus and filtering facepieces.  Laboratory tests and practical performance tests are included for the assessment of compliance with the requirements.

This European Standard specifies particle filters for use as components in unassisted respiratory protective devices with the exception of escape apparatus and filtering facepieces.  Laboratory tests are included for the assessment of compliance with the requirements.  Some filters complying with this European Standard may also be suitable for use with other types of respiratory protective devices and, if so, shall be tested and marked according to the appropriate European Standard.

This European Standard specifies gas filters and combined filters for use as components in unassisted respiratory protective devices. AX filters against low boiling organic compounds, SX filters against specific named compounds and CO filters are excluded.  Laboratory tests are   included for the assessment of compliance with the requirements.  Some filters complying with this standard may also be suitable for use with other types of respiratory protective devices and if so shall be tested and marked according to the appropriate European Standard.

This European Standard refers to particle filters for use as components in unassisted respiratory protective devices, except escape apparatus and filtering facepieces.   Laboratory tests are included for the assessment of compliance with the requirements.   Some filters complying with this standard may also be suitable for use with order types of respiratory protective devices and if so shall be tested and marked according to the appropriate European Standard.
