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 17255-1 relates specifically to the handling of the data. It defines the calculations to be carried out to

produce the data outputs that DAHS provide. It specifies the minimum outputs required to meet the

requirements of legislation such as the European Industrial Emissions Directive (IED) and the regulations

defining the European Pollutant Release and Transfer Register (E-PRTR). The calculations are based on

the requirements in these directives and regulations. These two reporting requirements form the basis

of this series of standards. However, although DAHS can provide other data outputs, such calculations are

outside the scope of this standard. The European emissions trading regulation defines different validation

and procedures for missing data, but the general principles in this standard can be used.

For the purposes of this document, the following terms and definitions 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 http://www.iso.org/obp
3.1
data acquisition and handling system
DAHS

system, which automatically receives, processes, stores and outputs data from automated measuring

systems
3.2
automated measuring system
AMS

measuring system permanently installed on site for continuous monitoring of emissions or measurement

of peripheral parameters
[SOURCE: EN 14181]

Note 1 to entry: Apart from the analyser, an AMS includes facilities for taking samples (e.g. probe, sample gas

lines, flow meters and regulator, delivery pump) and for sample conditioning (e.g. dust filter, pre-separator for

interferents, cooler, converter). This definition also includes testing and adjusting devices that are required for

functional checks and, if applicable, for commissioning.

Note 2 to entry: The term “automated measuring system” (AMS) is typically used in Europe. The term

“continuous emission monitoring system” (CEMS) is also typically used in the UK and USA.

---------------------- Page: 8 ----------------------
SIST EN 17255-1:2019
EN 17255-1:2019 (E)

Note 3 to entry: An AMS can provide data on reportable quantities (e.g. mass concentration of a pollutant),

peripheral parameters used to adjust the data (e.g. oxygen) or measured quantities which are subsequently

combined with other data to form reported data (e.g. flow subsequently used with mass concentration to form mass

emission data).
3.3
measurand
particular quantity subject to measurement
[SOURCE: EN 15259:2007]

Note 1 to entry: The measurand is a quantifiable property of the stack gas, for example mass concentration of a

measured component, temperature, velocity, mass flow, oxygen content and water vapour content.

3.4
peripheral parameter

specified physical or chemical quantity which is needed for conversion of measured values to specified

conditions
[SOURCE: EN 14181:2014]

Note 1 to entry: Peripheral parameters are called “reference quantities” in EN 15259.

Note 2 to entry: Peripheral parameters for standardizing the mass concentration of a pollutant are for instance

the concentration of oxygen, concentration of water vapour, temperature, and pressure.

3.5
plant process parameter
specified quantity describing plant conditions or other plant information
3.6
emission limit value
ELV

limit value given in regulations such as EU Directives, ordinances, administrative regulations, permits,

licences, authorisations or consents

Note 1 to entry: ELV can be stated as concentration limits expressed as half-hourly, hourly and daily averaged

values, or mass flow limits expressed as hourly, daily, weekly, monthly or annually aggregated values.

Note 2 to entry: ELV is mostly stated at standard conditions for dry gas and at a reference oxygen concentration.

3.7
maximum permissible uncertainty

uncertainty requirement on AMS measured values given by legislation or competent authorities

[SOURCE: EN 14181:2014]
3.8
legislation
directives, acts, ordinances and regulations

EN 17255-1:2019 (E)
3.9
calibration function

linear relationship between the values of the SRM and the AMS with the assumption of a constant residual

standard deviation
[SOURCE: EN 14181:2014]
Note 1 to entry: The calibration function is determined in QAL2.

Note 2 to entry: EN 13284-2 allows the use of quadratic calibration functions in specific cases.

3.10
valid calibration range

range of calibrated measured values at standard conditions determined during QAL2 or AST

Note 1 to entry: The valid calibration range is defined in EN 14181 and EN ISO 16911-2.

3.11
measurement range

range of values that the raw data from an AMS can lie within and be considered valid

Note 1 to entry: For AMS using an analogue 4 mA to 20 mA output the measurement range is conventionally

taken as being equivalent to the 4 mA to 20 mA range. For analogue and digital data the valid range of values can be

defined by legislation, derived from instrument testing or be an internal configuration of the AMS.

Note 2 to entry: The measurement range is not the same as the calibration range as the calibration range is

defined in terms of standardized calibrated values.
3.12
data
recorded value with associated information
Note 1 to entry: Associated information can be status signals.
3.13
raw data

value received directly from the AMS, optionally after scaling e.g. to units representing concentrations,

and associated status signals

Note 1 to entry: Status signals can be the status of the measured values or plant operation status.

3.14
valid data

data which are deemed to have passed particular quality requirements related to a specified usage

3.15
data product

defined data, recorded or calculated from input data, with a specified method of determination, and

available to the user of the DAHS as a recognised data set
Note 1 to entry: Examples specified in this standard include FLD, STA and LTA.

SIST EN 17255-1:2019
EN 17255-1:2019 (E)
3.16
first level data
FLD

raw data or average values calculated from the raw data, both including status signals

Note 1 to entry: The raw data can be converted to concentration units.
3.17
standardized first level data
SFLD

first level data calibrated and converted to standard conditions using peripheral first level data

Note 1 to entry: This value is not for compliance assessment but can used to provide data that are used by the

operator for process or abatement control or optimization.
3.18
status signal

binary value or enumerated value from the plant, AMS or operation personnel signifying a specific state

of operation
3.19
binary value
value which can assume one of two discrete values

Note 1 to entry: The two discrete values are usually associated with the Boolean values 0 and 1, FALSE and TRUE.

Note 2 to entry: Binary values can be received from the plant, be generated by the DAHS, from the AMS or be

keyed in by the operator's personnel.
3.20
enumerated value
value which can only assume one of a number of defined states
3.21
average
arithmetic mean of valid data over a specified time period T

Note 1 to entry: The time period over which the average is calculated can be fixed, rolling, partial or accumulating.

3.22
accumulating average

arithmetic mean of valid data over a time period with a fixed starting point and floating end point up to a

limit T

Note 1 to entry: An accumulating average can be calculated as an average in which the time period begins at

midnight or any integral multiple of a specified time period T thereafter. With t being the time between two data

samples, an accumulating average is calculated during each period of length T. During the time of calculation, the

average period increases from t to T as the number of data included in the calculation is increased from 1 to T/t.

The accumulating average is calculated at the end of each time period t.

Note 2 to entry: At the end of each time period T the accumulating average is the same as the block average over

the same time period.

Note 3 to entry: Accumulating averages are not used for emissions reporting but can be used by operators for an

early identification of possible exceedances of an emission limit value.

of this time period thereafter. The block average is calculated at the end of each time period.

3.24
rolling average
average over a fixed time period and calculated at regular time intervals
3.25
short-term average
STA
average related to the shortest time period used for reporting

Note 1 to entry: Short-term averages are based on the shortest time period of averages the plant shall report to

the authorities for each measured component. According to variations in different EU Directives the shortest time

period can be 10 min, 30 min or 1 h, depending on the type and application of the plant.

3.26
standardized short-term average
SSTA

short-term average converted to standard conditions using short-term averages of peripheral

parameters
3.27
cumulative standardized short-term average
CSSTA

value determined according to the calculation for a standardized short-term average but determined as

an accumulated average calculated over a shorter time period

Note 1 to entry: This value is not for reporting. It can be used to provide an indication of whether the next SSTA

value is likely to exceed an ELV, before the full STA period has elapsed, potentially allowing for mitigating actions.

3.28
validated short-term average
VSTA

standardized short-term average with the relevant confidence interval subtracted to comply with EU

Directive reporting requirements
