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

the reported values 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

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

and validation.

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

EN 17255-2 specifies the implementation of the calculations laid down in EN 17255-1 and the specific

requirements on functionality of the DAHS.

1 Scope

This document specifies the performance requirements on data acquisition and handling systems (DAHS)

regarding implementation of the procedures defined in EN 17255-1 including
— data acquisition;
— data processing;
— data storage;
— data output;
— generation of reports;
— system functions;
— data integrity;
— documentation.

This document supports the requirements of EN 14181 and legislation such as the IED and E-PRTR. It

does not preclude the use of additional features and functions provided the minimum requirements of

this document are met and that these features do not adversely affect data quality, clarity or access.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 17255-1 and the following apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
warning signal
binary value or enumerated value signifying the need for action

Note 1 to entry: Warnings can be derived from measurement values or conditions, which are still within the

specified limits, but where the value is close to the specified limit. Warnings are for the benefit of the plant operator.

---------------------- Page: 8 ----------------------
SIST EN 17255-2:2020
EN 17255-2:2020 (E)

Note 2 to entry: Warnings can be conditions communicated to the plant operator as requiring attention.

Instrument conditions like operation exceeding the upper limit of the valid calibration range are also considered as

warnings.
3.2
alarm signal
binary value or enumerated value indicating an alarm state

Note 1 to entry: Examples of alarm signals are incidents where an ELV is exceeded,

Note 2 to entry: Examples of alarm signals from instruments include conditions such as out of operation, and

operation conditions like measurements outside the measurement range.

Note 3 to entry: A condition, which leads to an alarm, can lead to a violation, if it persists too long according to

directives, local permits or other standards.

Note 4 to entry: Alarms are conditions communicated to the plant operator indicating that the plant if it continues

in this state could enter into a condition where it is not any longer fulfilling the relevant directive conditions.

3.3
violation signal

binary value or enumerated value indicating presence of a condition where requirements of directives,

operating permits or other standards are exceeded

Note 1 to entry: Measured values above ELV at a duration exceeding the limit in the directives can cause a

violation signal.

Note 2 to entry: Instrument conditions like too many hours out of operation, and operation conditions like

exceeding the valid calibration range for too many time periods related to the short-term average can cause

violation signals.
3.4
data storage
electronic memory capacity to hold data for processing or documentation

Note 1 to entry: This document does not prescribe storage technology. It is always the responsibility of the plant

operator that the capacity and reliability of the chosen storage is sufficient.
3.5
permanent data storage

non-volatile data storage with the capacity to hold data for a period equal to or exceeding a required

minimum time period
3.6
event
occurrence that could affect the performance or processing of the DAHS

Note 1 to entry: Events can be caused by an operator, e.g. by adding or changing configuration data, peripheral

data, limit values, QAL2 data or basic information, or by the system itself, e.g. for watchdog restart, change to or

from DST, recovery from power cut, performing automatic backup, reporting lack of communication with AMS or

external data loggers, or generating reports.

5 Principles

This document specifies minimum requirements for the performance and functional capabilities of DAHS.

The minimum functional capabilities specified in this document are considered to be necessary to meet

the requirements of the relevant regulations (e.g. EU Directives) in terms of the provision of emissions

data for reporting. These functional capabilities also cover the traceability, security and ability to audit

reported data.
The DAHS provides the time stamp for input data.
