C.4.4 High temperature test

Carry out the test at not less than the temperature and not more than the temperature + 25 °С and for the appropriate period of time specified in Table 2. Record electrical, flow and or pressure and temperature measurements at intervals not exceeding 2 min. Correct the static pressure measurements for the effects of density change due to temperature.

After 15 minutes, switch off the ventilator for 2 minutes, then restart the ventilator. During this period the temperature variation may exceed the specified limits. Add the time the ventilator is switched off to the period of the test.

C.4.5 High temperature test in accordance with temperature time curve

Increase the gas temperature at the intake plane of the ventilator in accordance with the standard time/temperature curve defined in ISO 834-1. Control the temperature to a tolerance of 0 to + 25 °С. Test the ventilator for a period of 30 minutes. Record electrical, flow and or pressure and temperature measurements at intervals not exceeding 2 min. Correct the static pressure measurements for the effects of density change due to temperature. At the end of this period switch off the ventilator for 2 minutes and then re-start the ventilator. During this period the temperature variation may exceed the specified limits. The test is completed once the fan has re-started and meets the requirements of C.l.

During the entire period of the test (for products intended to be installed within a building) observe the emissions of any smoke from the furnace coming from the housing of the ventilator due to distortion/leakage of the housing.

Test method for resistance to temperature of electric motors for use in powered
ventilators

D.l Principle

The resistance to temperature of electric motors for use in powered ventilators is proved by testing the motor at elevated temperature either in a powered ventilator or in conjunction with a generator or other method of providing the load. The motor is shown to be functioning satisfactorily by continuing to give the required output power and meeting the requirements of clause 4.2 and 6.1.2.

D.2 General

Test motors mounted within the airstream for ventilator Class F200, F300, F400 and F600 to this procedure. Test motors that are mounted outside the airstream with the impeller mounted on the motor shaft and motors for ventilator Class F842 as a unit with the ventilator.

D.3 Tests in association with a powered ventilator

Test the motor in a powered smoke ventilator in accordance with annex C.

D.4 Tests in association with a load

D.4.1 Apparatus

D.4.1.1 Test installation

Mount the motor on a stable support in an enclosure that has a minimum radial dimension . twice the maximum motor dimension.

Link it via a coupling and transmission shaft to an adjustable external load, such as a generator, which will absorb the power output of the motor.

To circulate the hot gas past the carcase at the rated velocity fit either the normal integral cooling impeller if the motor is not normally mounted in the fan airstream or an external impeller if the motor is mounted within the fan airstream. Mount the external impeller either directly on the motor shaft or on the transmission shaft.

Provide means of applying axial and radial load to the motor shaft. For example apply the axial load by rigidly connecting the motor to an external load generator that is free to move axially and so can be used to convert a stationary axial load to one that rotates. See Figure D.l.

2. Fixed support

5. Flexible couplings, torsionally rigid

6. Generator

7. Mass

8. Axial load, induced by mass (7)

9. Furnace

10. Penetration point

Figure D.l — Typical method of applying radial and axial load to a motor

D.4.1.2 Temperature measurements

Fit a furnace thermocouple approximately 100 mm upstream of the motor on the motor axis of rotation to measure the temperature of the incoming gases. Fit a single device at the fins of the motor for surface temperature measurement.

D.4.1.3 Electrical measurements

Fit equipment to measure frequency, voltage, current, power and speed in accordance with IEC 34-2 and ISO 5801.

D.4.2 Test specimens

Select test specimens in accordance with annexes A and B.

D.4.3 Test procedure

D.4.3.1 General conditions

Carry out the tests at an ambient temperature between 15 °С and 40 °С.

D.4.3.2 Warm up period

Operate the motor at ambient temperature at its rated frequency and voltage at 80 % to 100 % of the maximum rated power, at the maximum speed or if the motor is a two speed motor designed for continuous operation at low speed only, at the lower speed. Monitor the surface temperature of the motor until the rate of temperature increase is less than 2 °С in 10 minutes. Record electrical and temperature measurements.

Increase the temperature at the air intake of the motor to that specified in Table 2 within a period of not more than 10 minutes or not less than 5 minutes. Record electrical and temperature measurements during this period. Adjust the motor input power to F times the rated power at a density of 1,2 kg/m³, where F is as follows:

0,88 at a temperature of 200 °С

0,80 at a temperature of 300 °С

0,76 at a temperature of 400 °С

0,60 at a temperature of 600 °С

These factors do not apply to motors approved in the fans in which they are to be used, as the change of temperature causes all the effects that will change the power. However the factors established for one range of fans cannot be used for another.

D.4.3.3 High temperature test

Carry out the test at not less than the specified temperature, and not more than the specified temperature + 25 °С and for the appropriate period of time specified in Table 2. Record electrical, flow and or pressure and temperature measurements at intervals not exceeding 2 min.D.5 Test report

(normative)

Test method for operation under load

E.l Objective of test

The objective of this test is to establish the ability of the installed ventilator to operate at the critical operation condition, i.e. against an applied wind and snow load.

E.2 Test apparatus

Use a suitable test rig onto which the ventilator can be mounted and subjected to a test load equivalent to a wind pressure of 200 pa, when required as defined in 6.4, and a snow load as defined in 6.5. Apply the test load by one of the following methods:

1. plates;

2. bags containing up to 5 kg of solid particles or liquid;

Spread the loads over the whole of the external surface of the individual elements of the opening parts of the ventilator, to produce a uniformly distributed load.

E.3 Test specimen

A test on the largest ventilator of a range shall be considered representative of all ventilators in a particular range.

E.4 Test procedure

Mount the ventilator on the test rig in accordance with the supplier’s recommendations.

Apply the load using one of the methods given in E.2, increasing the load to the upper appropriate limit given in sections 6.4 and 6.5 and maintain the load for 10 ± 1 min.

Remove the load, actuate the ventilator and check that the dampers, flaps or louvres open to the design position.

Operate the ventilator against the design load three times, using the energy source as specified by the supplier and its fire activating mechanism. Determine if the fire operating position is reached each time.

E.5 Evaluation of test results

The ventilator meets the requirement of 6.4 and 6.5 if the test specimen achieves the operating position in each of the tests in less than 30 seconds. The test results may be applied to all ventilators of the same range., Annex ZA
