Not classified6.1.2For products intended to be installed within a building, there shall be no significantleakage of smoke from the furnace coming from the housing of the ventilator during theentire test period6.1.3At the appropriate temperature given in Table 2, a ventilator shall function for not lessthan the appropriate minimum time, and shall re-start, when tested in accordance withannex C.Table 2 — Test temperature and functioning time according toclassificationClassTemperatureMinimum functioning period°CminutesF200200120F30030060F400400120F60060060F84284230Not classifiedas specifiedas specifiedby sponsorby sponsor6.2 Flow and pressureWhen tested in accordance with annex C, at the appropriate temperature and for theappropriate time given in Table 2, the volume flow shall not change by more than 10 % or thestatic pressure shall not change by more than 20 % of that measured at the end of the warm upperiod of the test.

Increases above those specified may increase the fire risk.6.4 Wind loadIf the ventilator is designed to be installed at the atmospheric termination of a system and isfitted with flaps or louvres and these project above the wind deflectors (cowl or wind shield),the flaps or louvres shall open in less than 30 s against of a load of 200 Pa, when theventilator is tested in accordance with annex E.6.5 Snow load6.5.1 If the ventilator is designed to be installed at the atmospheric termination of a system,the ventilator shall be classified as one of the following:— SL 0— SL 125— SL 250— SL 500— SL 1000— SL ANOTE
The designations 0, 125, 250, 500, 1000 and A represent the test snow load in Pascalsapplied when the ventilator is tested in accordance with annex E The "A" in SLA will be replaced bythe test snow load when this exceeds 1000, or by the test load if one of the four defined values is notused.Where the minimum angle of installation (combining roof pitch and ventilator pitch)recommended by the supplier exceeds 45°, the ventilator takes the classification SL 1000without a test; except where the snow will be prevented from slipping from the ventilator e.g.by wind deflectors.

The following types of ventilators may be suitable for use on heated buildings without asnow load classification test:a) vertical discharge units without flaps or dampers;b) vertical discharge units with uninsulated metal flaps or dampers.6.6 Operation at low temperatureA powered ventilator with a separate device for the operation of the dampers, flaps or louvres,which does not use the air pressure from the fan, shall conform to 7.3 of prEN 12101-2:1995,when tested in accordance with annex E of prEN 12101-2:1995.6.7 ReliabilityA powered ventilator with dampers, flaps or louvres or a separate device for the operation ofthe dampers, flaps or louvres, which does not use the air pressure from the fan, shall conformto 7.1 of prEN 12101-2:1995 when tested in accordance with annex C of prEN 12101-2:1995.6.8 Performance data of ventilators6.8.1 The supplier shall provide a data sheet giving the aerodynamic and acousticperformance data of the ventilator assessed at ambient temperature in accordance withISO 5801, taking into account the reduction in performance caused by the increasedclearances required for high temperature.NOTE
It is permissible to convert these figures to determine the performance with hot gases and atother speeds of rotation using the scaling formulae from ISO 5801, with due allowance for tipclearance effects.6.8.2 If a ventilator is designed to be fitted with a duct for cooling air the data sheet shallinclude the volume pressure characteristic of the auxiliary system and the minimum coolingair flow required.

Tests previouslyperformed in accordance with the provisions of this standard (e.g. same product, samecharacteristic(s), test method, sampling procedure, system of evaluation of conformity) maybe taken into account. In addition, initial type testing shall be performed at the beginning ofthe production of a new product type or at the beginning of a new method of production(where these may affect the stated properties).All characteristics given in clauses 5 and 6.1 to 6.7 shall be subject to initial type testing.

the ventilator with the most highly stressed impeller, or the ventilators withimpellers in which the individual stress in any material, weld or fastening is thehighest, as appropriate (see A.4); b)
for ventilators with motors mounted in an enclosure which restricts the cooling, theworst case shall be tested, for example the ventilator with the ratio of motor crosssectional area to the minimum cross sectional area through which the cooling airflows; c)
at least two sizes are tested at their highest rotational speed; d)
the ventilator with the smallest motor frame size to be used; e)
if the highest impeller stress levels are determined by geometric similarityconditions from A.4.1, sufficient sizes of ventilators to ensure that the impellerdiameters of the range are from 0,8 to 1,26 of those tested; f)
if the highest impeller stress levels are determined by the calculation methods inA.4.2, sufficient sizes of ventilators to ensure that the impeller diameters of therange are from 0,63 to 1,26 of those tested.A.2 MotorsA product range shall only be approved if the motors used in the range are also approved,except when the impeller is not mounted on the motor shaft and the motors are out of theairstream in ambient air and the cooling of the motor is not affected by heat transfer from theventilator or the ventilator construction. When the motor is out of the airstream and theimpeller is mounted on the motor shaft, motors from a different supplier to the one used inthe ventilator test may be used, provided that the tested and alternative motors are of the sameconstruction, i.e. same class of insulation and bearing type and class of fit and samesynchronous speed and rating.A.3 Combined testingThe tests to approve ventilators and motors may be performed at the same time. The motorapproval procedure is given in annexes B and D. Motors tested independently of fans or inanother range of ventilators may also be used provided these tests have been undertaken withsimilar mechanical loads and cooling conditions as described in this annex and annex D.

The method given for calculating stresses is for comparative purposes only and is notsuitable for design assessment. It only takes into account centrifugally induced stresses asaerodynamically induced stresses are of less importance.A.4.2.1 Axial impellersA.4.2.1.1 Centrifugal forceDivide the blade into four parts using five sections as shown in Figure A.1.Calculate the centrifugal force for each part as follows2n1nn1n1nn1+nn,2)()-(2)(RRRRAAFWhereFn,n+1is the centrifugal force in Newtons of the part of the blade between sections nand n+1; is the density in kg/m3;Anis the area of section n in m2;Rnis the radius of section n;is the angular velocity in radians/s.
