ANNEX III

MEASUREMENTS AND CALCULATIONS

1.

For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards the reference numbers of which have been published for this purpose in the Official Journal of the European Union , or using other reliable, accurate and reproducible methods that take into account the generally recognised state-of-the-art methods, in line with provisions set out in points 2 to 8.

In the absence of existing relevant standards and until the publication of the references of the relevant harmonised standards in the Official Journal, the transitional testing methods set out in Table 2, or other reliable, accurate and reproducible methods, which take into account the generally recognised state-of-the-art methods, shall be used, in line with provisions sent out in points 2 to 8.

Manufacturers, importers or authorised representatives shall use the declared values of the parameters referred to in Article 4(2) for the calculations in this Annex.

2.

For the purpose of assessing compliance with the requirements of this Regulation and provided that reliable, accurate and reproducible test- and calculation methods are used, the manufacturer:

(a)

may remove the elements that are not significant elements as defined in Article 2, point (2);

(b)

may conduct the tests with the geometrical equivalent of the stator inner surface;

(c)

may conduct the tests with a scale model of the fan and calculate the results for the real-size fan if the fan has an impeller diameter above 1 m for jet fans or 0,5 m for other fans;

(d)

may conduct the tests at customer’s or manufacturer’s site if the fan has an impeller diameter above 1 m for jet fans or 0,5 m for other fans.

3.

The compliance of fans with multiple speed motors shall be determined at the power and speed corresponding to the highest speed made available to the customer.

The compliance of fans of which the blade pitch angle can be adjusted to fulfil the customer’s duty point shall be determined using the least favourable pitch configuration made available to the customer.

4.

Fan flow angle

The fan flow angle α is calculated as the average value of angles α 1 and α 2 following the formula:

where:

α 1 is the angle to the direction of the rotational axis of the tangent at the hub at the intersection of the blade trailing edge with the hub;

α 2 is the angle to the direction of the rotational axis of the tangent at the shroud or at the outer diameter of the blade at the intersection of the blade trailing edge with the shroud or with the outer diameter of the blade, given that, if the hub and/or shroud are not axisymmetric, angles α 1 and α 2 are the average values in circumferential direction.

An impeller defined as ‘axial’ if α < 20°, ‘mixed-flow’ if 20° ≤ α < 70° and ‘centrifugal’ if α ≥ 70°.

5.

Centrifugal blade angle

‘Centrifugal blade angle β 2 means the angle between the tangent to the outer circumference of the outer circle, as defined by the trailing edge of the blades, and a line bisecting the trailing edge of the blade. To consider blade designs that have a rapid change of angle at the trailing edge, the angle is the arithmetic mean along 50 % of the trailing length of the blade. The trailing edge of the blade is the edge at the tip of the blade at the outlet of the impeller. A centrifugal impeller is defined as ‘backward curved’ if 0° < β 2 ≤ 50°, ‘backward inclined’ if 50° < β 2 ≤ 90° and ‘forward-curved’ if β 2 > 90°.

for centrifugal fans declared as backward inclined fans, or as forward curved fans and driven by a motor with an electric input power < 5 kW: use the fan type and N value corresponding to ‘other centrifugal fan’ if the determined value of β 2 is less than 47°;

(b)

for centrifugal fans declared as backward inclined fans and driven by a motor with an electric input power Pe >= 5 kW: use the fan type and N value corresponding to ‘other centrifugal fan’ if the determined value of β 2 is more than 93°;

(c)

for fans declared as axial fans, efficiency category ‘total’: use the fan type and N value corresponding to ‘mixed flow fans’ if the determined value of α is more than 23°;

(d)

for fans declared as axial fans or mixed flow fans , efficiency category ‘static’: use the N value directly resulting from the determined value of α.

9.

The Member State authorities shall, without delay, provide all relevant information to the authorities of the other Member States and to the Commission through the information and communication referred to in Article 34 of Regulation (EU) 2019/1020 of the European Parliament and of the Council  ( 1 ) after a decision is taken on the non-compliance of the model according to points 2, 4, 5(a), 7 or 11.

10.

The Member State authorities shall use the measurement and calculation methods set out in Annex III.

11.

When the Member State authorities verify the performance curves referred to in point 3 of Annex II, a minimum of two declared test points for each of the characteristic curves shall be tested, in line with points 3 to 10 above, taking into account points 12 to 14 below. If one of the declared test points is found non-compliant, the model and all equivalent models shall be considered non-compliant with this Regulation.

12.

Member State authorities may decide to undertake the verification procedure of fans with an impeller diameter above 1 m for jet fans or 0,5 m for other fans at the premises of manufacturers, authorised representatives or importers before the products are put into service. The Member State authority can do this verification using its own testing equipment.

13.

If factory acceptance tests are planned for such fans, which will test parameters laid down in Annex II of this Regulation, the Member State authorities may decide to use witnessed testing during these factory acceptance tests to gather test results which can be used to verify compliance of the fan under investigation. The authorities may request a manufacturer, authorised representative or importer to disclose information on any planned factory acceptance tests relevant for witnessed testing.

14.

In the cases mentioned in points 12 and 13, the Member State authorities only need to verify one single unit of the model. If the results referred to in point 3(b)(iv) and 3(b)(v) are not achieved, the model and all equivalent models shall be considered not to comply with this Regulation.

15.

When testing fans at partial load, the Member State authorities shall use a variable speed drive without filters, with a view to minimising VSD energy losses.

16.

The Member State authorities shall only apply the verification tolerances set out in Table 3 and shall only use the procedure described in this Annex for the requirements referred to in this Annex. For the parameters in Table 3, no other tolerances such as those set out in harmonised standards or in any other measurement method shall be applied.

Parameters

Verification tolerances

Fan efficiency ( η )

The determined value* shall not be lower than the value representing 93 % of the corresponding declared value at BEP or T m , and not be lower than the value representing 85 % of the corresponding declared value at partial load.

Electric input power ( P e

)

The determined value* shall not be higher than the value representing 107 % of the corresponding declared value at BEP or T m , and not be higher than the value representing 110 % of the corresponding declared value at partial load.

Volume flow rate ( q v

)

The determined value* shall not differ by more than 5 % from the corresponding declared value at BEP or T m , and not more than 10 % than the corresponding declared value at partial load.

Pressure difference ( Δp ), ‘fan static pressure’ (p fs ) or ‘fan pressure’ (p f )

The determined value* shall not differ by more than 5 % from the corresponding declared value at BEP, and not more than 10 % than the corresponding declared value at partial load.

Fan speed (rpm)

The determined value* shall not differ by more than 2 % from the corresponding declared value.

Characteristic noise emission value (L)

For fan declared as low noise fans: the determined value* shall not exceed the declared value of 32 dB by more than 3 dB with respect to 1 pW.

*

Where three additional units are tested in accordance with point 5(b), the determined value means the arithmetical mean of the values determined for those three additional units.

INDICATIVE ENCHMARKS

The maximum values relate to the achievable efficiency grade N (minimum efficiency formulas are set out in Annex II) with clean air and no space and/or noise restrictions. The minimum values apply to contaminated air (some dust load) and space, noise and/or other operational restrictions at the limit of what is still in scope according to the exemptions in Article 1.
