BS EN 13274-2:2001 – Respiratory protective devices — Methods of test — Part 2: Practical performance tests

1 Scope
This European Standard specifies practical performance tests for respiratory protective devices, except for diving apparatus. The purpose of these tests is to subjectively assess certain properties, characteristics and functions of the device, when worn by test subjects in simulated practical use, which cannot be assessed by tests described in other standards.
2 Normative references
This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references subsequent amendments to, or revisions of, any of these publications, apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
EN 132, Respiratory protective devices — Definitions of terms and pictograms.
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1 32 apply.
4 Prerequisites
In order to implement this part of EN 13274, at least the following parameters need to be specified in the relevant device standard:
– the number of samples;
– device preparation;
– any prior conditioning or testing;
– the number and selection of test subjects;
– activity sequence, if relevant;
– deviations;
– pass/fail criteria;
– identification of activities (by number in Table 1), and specification of relevant times
including the total time;
5 General test requirements
Unless otherwise specified, the values stated in this European Standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subject to a tolerance of ±5 %. Unless otherwise specified, the ambient temperature for testing shall be between 1 6 °C and 32 °C and the temperature limits shall be subject to an accuracy of ±1 °C.
6 Test methods 6.1 Principle Test subjects donning and wearing the device in accordance with the information supplied by the manufacturer perform activities in simulation of practical use. They are then asked to assess the device subjectively and comment accordingly.
6.2 Test subjects Before performing any tests involving human subjects, account shall be taken of any national regulations concerning the medical history, examination or supervision of the test subjects. Test subjects who are experienced in wearing the type of respiratory protective device being tested shall be used. The medical condition of the subjects shall be satisfactory for the tasks involved. The necessity for a medical examination before the tests and for medical supervision during them is at the discretion of the appropriate responsible person of the test house.
