Stationary source emissions - Manual method for the determination of the mass concentration of formaldehyde - Reference method

Stationary source emissions - Manual method for the determination of the mass concentration of formaldehyde - Reference method

This document specifies the reference method for the determination of the concentration of formaldehyde in emissions from stationary sources. Waste gas samples are taken by absorption in water and subsequently analysed by spectrophotometry or HPLC. The method applies to waste gases in which the formaldehyde concentration is 2 mg/m3 to 60 mg/m3, on dry basis, at the reference conditions of 273 K and 101,3 kPa.
The specific components and the requirements for the measuring system are described. A number of performance characteristics with associated minimum performance criteria are specified for the measuring system.

Fugitive and diffuse emissions of common concern to industry sectors - Standard method to determine diffuse emissions of volatile organic compounds into the atmosphere
SIST EN 17628:2022

This document specifies the framework for determining emissions to the atmosphere of Volatile Organic Compounds (VOCs). It specifies a system of methods to detect and/or identify and/or quantify VOC emissions from industrial sources. These methods include Optical Gas Imaging (OGI), Differential Absorption Lidar (DIAL), Solar Occultation Flux (SOF), Tracer Correlation (TC), and Reverse Dispersion Modelling (RDM). It specifies the methodologies for carrying out all the above, and also the performance requirements and capabilities of the direct monitoring methods, the requirements for the results and their measurement uncertainties.
This document specifically addresses, but is not restricted to, the petrochemicals, oil refining, and chemical industries receiving, processing, storing, and/or exporting of VOCs, and includes the emissions of VOCs from the natural gas processing/conditioning industry and the storage of natural gas and similar fuels. The methods specified in this document have been validated at onshore facilities.
This document is applicable to diffuse VOC emissions to atmosphere but not to the emissions of VOCs into water and into solid materials such as soils. It is complementary to EN 15446 [9], the standardized method for the detection, localization of sources (individual leaks from equipment and piping), and quantification of fugitive VOC emissions within the scope of a Leak Detection and Repair Programme (LDAR).
This document has been validated for non-methane VOCs, but the methodology is in principle applicable to methane and other gases.
This document specifies methods to determine (detect, identify and/or quantify) VOC emissions during the periods of monitoring. It does not address the extrapolation of emissions to time periods beyond the monitoring period.

SIST EN 16429:2021

This document specifies the standard reference method (SRM) based on an automatic method for determination of the mass concentration of hydrogen chloride (HCl) in ducts and stacks emitting to the atmosphere. It describes the sampling and gas conditioning system.
This document specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) using the infrared measurement method. It applies for periodic monitoring and for the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes.
The infrared measurement method described in this document can be used as a SRM, provided the expanded uncertainty of the method is less than 20 % relative at the daily Emission Limit Value (ELV), or 1 mg/m3 for ELV below 5 mg/m3, and the criteria associated to performance characteristics described in EN 15267-4 for portable automated measuring systems (P-AMS), are fulfilled.

Stationary source emissions - Determination of mass concentration of fluorinated compounds expressed as HF - Standard reference method
SIST-TS CEN/TS 17340:2020

This European Standard specifies a manual method for the determination of the concentration of fluorinated compounds expressed in HF. Two cases are presented:
- first case: the measurand is the concentration of hydrofluoric acid and gaseous and bound to particulates fluorides,
- second case: the measurand is the concentration of hydrofluoric acid and gaseous fluorides.
Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography.
This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes.
This document applies to more or less dust-laden flue gases whose HF concentration may vary between 0,1 mg/m3 and 10 mg/m3, at standard conditions of pressure and temperature. The quantification limit of the method is estimated at 0.1 mg/m3 for a sampled volume of 0.1 m3.

Stationary source emissions - Quality assurance and quality control procedures for automated dust arrestment plant monitors
SIST EN 17389:2020

This document specifies the quality assurance and quality control procedures related to automated dust arrestment plant monitors.
This document applies to two types of instruments commonly used for dust arrestment plant control purposes:
-   filter dust monitors that are configured in mass concentration units (e.g. mg/m3) and are used for dust arrestment control purposes;
-   filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of the dust pulses created by the cleaning process of the dust arrestment plant.
This document applies to instruments certified according to the requirements of EN 15859.
This document provides information on the configuration, ongoing quality assurance (with automatic internal zero point and reference point checks) and annual surveillance tests of instruments. This ensures that the instrument is providing information to demonstrate that the dust arrestment plant is working correctly and controlling dust pollution to the required levels.
The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with the standard reference method in EN 13284 1.
This document specifies the set-up of filter leakage monitors used to monitor a change in response caused by deterioration in the operation of the dust arrestment plant.
