European foreword

This document (EN 17255‑3:2021) has been prepared by Technical Committee CEN/TC 264 “Air quality”,

the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an identical

text or by endorsement, at the latest by April 2022, and conflicting national standards shall be withdrawn

at the latest by April 2022.

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 is Part 3 of the EN 17255 series.

The EN 17255 series, published under the general title “Stationary source emissions — Data acquisition

and handling systems”, specifies:
— requirements for the handling and reporting of data;
— requirements on data acquisition and handling systems;

— requirements for the performance test of data acquisition and handling systems;

— requirements for the installation and on-going quality assurance and quality control of data

acquisition and handling systems.

Any feedback and questions on this document should be directed to the users’ national standards body. A

complete listing of these bodies can be found on the CEN website.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following

countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus,

Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,

Introduction

This document forms part of a series of standards which, between them, govern the process for the quality

assurance of data received by a data acquisition and handling system (DAHS) from automated measuring

systems (AMS), being used for monitoring emissions from stationary sources and quality ensured to

EN 14181.

The input data can be either in analogue representation or in digital form directly from an AMS or via a

digital bus system. Inputs can include the data from the AMS, peripheral data needed for calculation of

reported data and information on plant conditions needed to apply data selection criteria.

The data acquisition and handling system (DAHS) receives the raw data, as they are measured, averaged

and presented by the AMS, and converts, averages, stores and reports data as required by legislation.

This series of standards suggests that the process of data handling is best performed in a dedicated DAHS.

It does not preclude the use of other options for all or part of the process provided that it can be shown

that they meet all of the requirements of the standard, particularly in relation to speed, accuracy, access,

security and validation.

This series of standards applies to DAHS installed after the date of implementation.

EN 17255‑3 specifies the performance test of DAHS.

NOTE 1 The certification of DAHS will be covered by the revised version of EN 15267‑1 [5], which is currently in

preparation.

NOTE 2 The manufacturing quality control of DAHS will be covered by the revised version of EN 15267‑2 [6],

which is currently in preparation.

The performance test shall be based on the scope of the intended applications of the DAHS specified by

the manufacturer on the basis of the corresponding legislation, e.g. large combustion plants or waste

incinerators under the IED. The test range shall cover the intended applications. Tests may be combined

for different applications sharing the same performance criteria.

The performance test of DAHS shall be based on the performance criteria specified in EN 17255‑1 and

EN 17255‑2. It consists of the following levels of testing:

a) documentation test: verification of the correct DAHS documentation for a characteristic in accordance

with the specified performance criterion;

b) generic test: demonstration of the capability of the DAHS to handle a characteristic in accordance with

the specified performance criterion without use of specific test equipment and test procedures;

c) specific test: test of a characteristic of the DAHS by use of specific test equipment and test procedures

to achieve a test result for comparison with the specified performance criterion.

The testing shall be carried out by a testing laboratory having the competence to perform the test

procedures specified in this document.

5 Performance testing process

The performance test shall be based on the scope of the intended applications of the DAHS specified by

the manufacturer on the basis of the corresponding legislation, e.g. large combustion plants or waste

incinerators under the IED. Tests may be combined for different applications sharing the same

performance criteria.

The performance test of DAHS shall be based on the performance criteria specified in EN 17255-1 and

EN 17255-2. It consists of the following levels of testing:

a) documentation test: verification of the correct DAHS documentation for a characteristic in accordance

with the specified performance criterion;

b) generic test: test of the capability of the DAHS to handle a characteristic in accordance with the

specified performance criterion;

c) specific test: test of a characteristic of the DAHS by use of specific test equipment and test procedures

to achieve a test result for comparison with the specified performance criterion.

NOTE A specific test is a check of the correct operation of the characteristic.

The testing shall be carried out by a test laboratory having the competence to perform the test procedures

specified in this document.

corresponding type of testing.

6 Test procedures
6.1 General

Clause 6 of this document specifies the test procedures for testing that the performance criteria specified

in EN 17255-1 and in EN 17255-2:2020, Clause 6, are fulfilled.

The numbers of the subclauses of Clause 6 of this document are identical to EN 17255-2:2020, Clause 6.

All relevant tests shall be performed on one DAHS in the laboratory within the environmental condition

limits specified by the manufacturer.

The test laboratory shall select an appropriate number of significant digits when testing a calculation

process to avoid that the test has a negative effect on the test results.
Tests can be performed in any order, unless otherwise specified.

The test laboratory shall document for each test procedure whether the DAHS meets the relevant

performance criteria. The environmental conditions pertaining during testing shall be recorded.

6.2 Data acquisition
6.2.1 Input data

The test laboratory shall demonstrate by a documentation test that the DAHS is designed to acquire the

following input data for the intended applications:
— emission data;
— peripheral data;
— flow data;
— plant process data;
— manually entered data.
