6.2 Measurement section 6.2.1 Measurement section and measurement plane The measurement section shall allow the sampling and execution of measurements at a suitable measurement plane. NOTE 1 The measurement section is the region of a conducted source (e.g. waste gas duct, stack) which includes the actual measurement plane and the inlet and outlet sections. SIST EN 15259:2008
as far downstream and upstream from any disturbance, which could produce a change in direction of flow (e.g. disturbances can be caused by bends, fans or partially closed dampers), – in a section of a duct with at least five hydraulic diameters of straight duct upstream of the sampling plane and two hydraulic diameters downstream (five hydraulic diameters from the top of a stack; see A.2) and – in a section of a duct with constant shape and cross-sectional area. NOTE 5 Effective aerodynamic arrangements (e.g. fans, vanes, ducting design) can be required to achieve mixing of the gases before entering the (straight) duct where the measurement section is located in order to get a homogeneous concentration profile at the measurement plane, especially when several gases of different characteristics in composition, coming from different installations are collected in the same duct. NOTE 6 It can be advisable to perform an exploratory velocity traverse before committing to a comprehensive installation. c) measurements at all the sampling points defined in 8.2 and Annex D shall prove that the gas stream at the measurement plane meets the following requirements: 1) angle of gas flow less than 15° with regard to duct axis; NOTE 7 A method for the determination of the angle of gas flow is given in Annex B of EN 13284-1:2001. 2) no local negative flow; 3) minimum velocity depending on the flow rate measuring method used (for Pitot tubes a differential pressure larger than 5 Pa); 4) ratio of the highest to lowest local gas velocities less than 3:1; NOTE 8 The above requirements are generally fulfilled in sections of duct with at least five hydraulic diameters of straight duct upstream of the measurement plane and two hydraulic diameters downstream (five hydraulic diameters from the top of a stack). Therefore, it is strongly recommended to design sampling locations accordingly. d) installation of measurement sections in vertical ducts should be preferred to installation in horizontal ducts; NOTE 9 At high dust concentrations, for some particle fractions, sedimentation can occur in horizontal ducts. This can lead to errors in the measurement of pollutants contained in the particle fraction, e.g. heavy metals, PCDD/PCDF. e) measurement section shall be situated where it is possible to erect suitable working platforms with the provision of the necessary infrastructure; SIST EN 15259:2008
NOTE 4 If the distance between a measurement port and the opposite interior wall of the waste gas duct is large (e.g. more than 2 m), depending on the measurement objective, two opposing measurement ports can be provided per measurement line, and the platform extended accordingly. In the case of rectangular ducts, the measurement ports should be installed on the longer side (see Figure A.6). 6.2.3 Working area and working platform 6.2.3.1 Load bearing capacity Permanent and temporary working platforms shall have a load bearing capacity sufficient to fulfil the measurement objective. NOTE Sampling can comprise of two to six persons with equipment weighing between 50 kg and 300 kg. Temporary working platforms shall be tied or supported to a permanent structure to prevent collapse or overturning. They shall be checked before use in accordance with national regulations on safety at work. 6.2.3.2 Position and working space Working platforms shall provide sufficient working area and height (working space) for the measurement objective, i.e. to manipulate the probes and operate the measuring instruments. Clearance area at the working platform shall be dimensioned appropriately. Probe introduction should not be impeded e.g. by guard fences and other built-in elements. NOTE 1 Grid measurements require a sufficiently large working area outside the waste gas duct along the measurement lines so that the measurement points can be sampled with the appropriate probes in the measurement plane. The minimum probe length depends on the internal diameter or depth of the waste gas duct and the wall thickness. NOTE 2 A sufficient depth of the working area is given by the sum of the internal diameter or depth of the waste gas duct and the wall thickness plus 1,5 m for flanged-on instruments (see A.2). If two opposite measurement ports are installed for one measurement line, a correspondingly smaller operating area depth is sufficient. NOTE 3 If the waste gas has a vertical direction of flow, both with round and rectangular waste gas ducts, a working height from the platform to the measurement lines can be established, which is approximately 1,2 m to 1,5 m.

6.3 Measurement site 6.3.1 Power supply and equipment Power connections of an appropriate size and safeguarded in accordance with national requirement shall be installed at the measurement site. Compressed air, water connections and wastewater disposal may be necessary. 6.3.2 Safety and environmental conditions The measurement sites shall be installed in such a way as to comply with national safety at work requirements. At least the following aspects shall be considered: easy and safe access to the measurement site; transport means, for example hoists or lifts [18], to transport measuring instruments, in the case of measurement sites which are not at ground level; avoidance of area of sources which emit unexpectedly, for example rupture disks, overpressure valves or steam discharges; avoidance of any hazard by engineering or procedural measures; avoidance of areas of significant positive pressure; availability of measures to ensure personnel carrying out the emission measurements are informed of any operating faults which would endanger them; possibility to accommodate the working platform or measurement site within the plant building; protection of the working area from heat and dust; protective measures, for example weather protection and heating, to ensure the necessary environmental conditions for the personnel and the equipment used.

measurements of emissions at comparable emission sources,
calculated or estimated mass flow of emissions, e.g. using data from the plant or its operation with the aid of balance sheets for individual substances and
data related to the process, e.g. knowledge of the relationship between the temperature curve of the process and emissions. Based on the information collected, the measurement objective shall be reviewed and amended, if necessary. 7.2 Measurement plan 7.2.1 Specification of measurement plan The measurement plan shall be specified on the basis of the measurement objective (see 7.1). NOTE Where measurements are being made for regulatory purposes, the customer can need approval of the measurement plan from the competent authority. In particular the following shall be specified: a) operating conditions of the plant including fuel or feedstock, waste gas components and reference quantities to be measured; b) timing and siting arrangements of the required individual measurements and measurement dates; c) measurement methods to be applied; d) measurement sections and measurement sites; e) technical supervisor, necessary personnel and auxiliary help for carrying out of the measurements; f) reporting arrangements. 7.2.2 Plant operating conditions and load characteristics The operating conditions of the plant, waste gas composition and reference quantities to be measured shall be specified in accordance with the measurement objective. The influence of the mode of plant operation, the feed materials, and the waste gas cleaning system in the plant on the emission shall be considered (examples are given in B.1). NOTE 1 An essential feature of the specification is the maximum plant output. This determines, for example,
in the case of combustion plants, the size and shape of the combustion space, the number of burners or number of transporters for combustible matter and the amount of combustible matter which can be fed and SIST EN 15259:2008
