Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
The following main technical changes have been made compared to EN 12942:1998:
a) Clause 4 Designation was deleted;
b) number of test samples was added to the requirements, where necessary;
c) classification table was amended to cover Hg and NO filter for all classes (TM1, TM2 and TM3);
d) nominal values and tolerances were added;
e) clogging was deleted;
f) warning facilities were amended to cover low energy and low flow warning;
g) visual inspection was changed to inspection and detailed list inserted;
h) test substances and number of test subjects for inward leakage test was changed;
i) test for noise level was adapted to the test procedure specified in ISO 16900-14:2020;
