Introduction
requirements of the test specification which may be a plete standard or part of a standard and successful practical performance tests have been carried out on plete apparatus where specified in theappropriate standard. If for any reason a plete apparatus is not tested then simulation of the apparatusis permitted provided the respiratory characteristics and weight distribution are similar to those of the plete apparatus.
1Scope
This European Standard specifies minimum requirements for full face masks for respiratory protective devices.
Full face masks for diving apparatus are not ineluded in the scope of this European Standard.
Laboratory and practical performance tests are included for the assessment of pliance with therequrements.

3 Definition
For the purposes of this standard the definitions given in EN 132 and the nomenclature given inEN 134 apply together with the following.
on the face of the wearer of a respiratory proteetive device against the ambient atmosphere when the skin A full face mask is a facepiece which covers the eyes nose mouth and chin and provides adequate sealingis dry or moist and even when the head is moved or when the wearer is speaking.
4Description
Air enters the full face mask through the connector(s) and passes either directly to the nose and mouth areaor via the eye (visor) area of the full face mask.
The exhaled air flows back either through the connector into the breathing apparatus (closed-cireuitbreathing apparatus pendulum breathing) or directly to the ambient atmosphere via the exhalationvalve(s) or by other appropriate means in other types of respiratory protective devices.
An inner mask may be used to separate the nose and mouth from the eye (visor) area(s) of the full facemask.
