European foreword
This document (CEN/TR 1404:2024) has been prepared by Technical Committee CEN/TC 238 “Test
gases, test pressures, appliance categories and gas appliance types”, the secretariat of which is held by
AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CR 1404:1994.
In comparison with CR 1404:1994, the following significant changes have been made:
emissions, an alternative to the correction formula derived from the BCR program (E.1) is
— for NOX
proposed by CETIAT (E.2), this alternative formula is based on measurements;
— characteristics to be checked before carrying out tests are explained (warming-up period, response
time, setting of zero or repeatability;
— the way to determine the main performances characteristics of analysers are more detailed
(linearity, drifts, interferences, measuring range and converter efficiency are more detailed;
— the calculation of the uncertainties of the measurements of NO and CO is no longer covered by this
X
document, and Annex III, Uncertainty calculation of NOX and CO measurements, has been deleted.
Any feedback and questions on this document should be directed to the users’ national standards body.
