EN 13030-2001 pdf download.Ventilation for buildings – Terminals – Performance testing of louvres subjected to simulated rain.
NOTE Flow meters can be calibrated in sdu by means of pitot static tube traverse techniques described in
ISO 3966.
5.1.3 Flow meters shall be checIed at intervals as appropriate but not exceeding 12 months. This
check can take the form of one of the following:
a) a dimensional check for all flow meters not requiring calibration;
b) a check calibration over their full range using the original method employed for initial calibration or meters calibrated in situ;
C) a check against a flow meter which meets the flow meter specification ISO 5221.
5.2 Wind Velocity Measurement
The wind velocity shall be measured using a pitot tube, vane anemometer or other similar style
instrument for which the measuring error does not exceed 2,0 %
5.3 Pressure Measurement
5.3.1 Pressure in the duct shall be measured by means of a liquid-filled calibrated pressure gauge, or any other device conforming to 5.3.2.
5.3.2 The maximum scale interval shall not be greater than the values given in Table 2 for the appropriate range of pressure gauges.
5.4 Temperature measurement
Measurement of temperature shall be by means of mercury-in-glass thermometers, resistance thermometers, or thermocouples. Instruments shall be graduated to give readings in intervals not greater than 0,5 K and calibrated up to the nearest 0,25 K.
5.5 Water flow meters
5.5.1 The measurement error of water flow meters shall not exceed 0,5 % of the indicated flow rate.
5.5.2 Water flow meters shall be calibrated against a known weight of water flowing for a measurement time period as specified in EN 24185.
5.6 Timers
The error limit for timers for determining water flow rates shall not exceed 0.2 s.
5.7 RaIn gauge
The error limit for rain gauges shall not exceed 2 % of the indicated reading.
6 Test apparatus
6.1 General
A diagram of the test apparatus is shown in Figure C.1 and the requirements for the various elements described in 6.2 to 6.8.
6.2 Wind simulation equipment
An external fan shall be titled to direct the air perpendicular to the weather louvre test plane, as illustrated in Figure C.2.
The air outlet of the fan and any silencing or straightening section shall not be less than 1 m diameter.
The fan shall be capable of producing an air velocity of 13 ms’ at a distance 1 m in front of the test plane of the weather louvre.
An air straightener section shall be assembled to the outlet of the fan to avoid swirling air currents.
A suitable air straightener is illustrated in Figure C.2. Other air straighteners (such as are described in ISO 5801 for fan tests) can also be used.
6.3 Weather section
The weather louvre or calibration plate to be tested shall be mounted and fixed in the centre of a
3 m x 3 m square wall at the rear of the weather section (see Figure C.2).
The weather louvre or the calibration plate as appropriate shall be tightly sealed to the wall, as
recommended by the manufacturer.
The outside face of the weather louvre shall be facing the wind and rain simulation equipment.
6.4 Rain simulation equipment
The simulated rain shall be produced by at least 4 nozzles in an array close to the discharge of the wind effect fan to suit the spread of rain required. A suitable spray can be achieved by using the nozzles and control system as shown in Figures C.2 and C.4 and annex A.
The rain simulation equipment shall satisfy the following requirements with the calibration plate mounted in the test opening.
a) The equipment shall be capable of producing a simulated rain penetration through the calibration plate of 75 l’h’ (+ 10% / 0 %) per square metre of opening:
b) The simulated rainfall rate measured using the rain gauge in the positions shown in Figure C.5 shall not deviate from the mean value by more than 15 %:
c) The water penetration through the calibration plate measured in the collection section shall be at least 80 % of the total water collected in both the weather section at the base, in front of the calibration plate. and the collection duct.
6.5 CollectIon duct
The collection duct (see Figure C.3) shall be sealed against the back of the weather section.
The collection duct shall have a water droplet elimination section at the downstream end to prevent carry over of airborne water droplets from the collection duct (see annex B).
The collection duct shall have an airtight connection to the air flow measuring plenum.
