It applies to electrically operated fans rated for less than 50 volts direct current (d.c.). Fans may
29、be of the centrifugal or axial flow type. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

34、quirements 4.1 Fans shall be designed to operate continuously at 120 % of nominal voltage. 4.2 Fans shall be ignition-protected in accordance with the requirements of IS0 8846. 4.3 Fans shall be rated for airflow. Fan airflow shall be measured in accordance with clause 6, and performance curves shal
35、l be available. 4.4 Materials used for fan blades or rotor and the housing shall be selected to prevent the creation of a spark should they contact each other. 4.5 Moving parts of fans shall, when necessary, be enclosed or fitted with guards for protection against injury. Enclosures shall be provide
36、d with drains to prevent the accumulation of water in all mounting positions. Enclosures and guards are not needed if contact with the fans moving parts is judged not to be harmful. 1) Published by Air Movement and Control Assoc., Inc. 30 West University Drive, Arlington Heights, IL 60004, USA. 8 BS

38、galvanically compatible in the presence of sea-water. 4.8 Components of fans shall be selected or coated to be resistant to corrosion in the presence of sea-water. 4.9 Installation instructions including a fan performance curve shall be available for each fan (see 6.2). 5 Electrical requirements 5.1
39、 Fans shall be of the 2-wire type, with both the power and return lines insulated from the motor and fan housing. 5.2 Conductors used for connection to the power supply shall be stranded copper. NOTE 1 A future International Standard will specify requirements for extra-low-voltage electrical install
40、ations. 5.3 If external terminals are provided, they shall be designed or shielded to prevent short-circuiting that could result from accidental contact by a conductive object. 6.4 If external motor leads are provided with the fan, they shall be sized in accordance with the power requirement but not
41、 less than a nominal 1 mm2. Conductor insulation shall be rated to be used in damp places and be suitable for 60 “C ambient temperature at 120 % of nominal voltage. 5.5 A fan shall be protected against continuous locked rotor conditions by: - integral overcurrent protection; or, - overcurrent protec
42、tion in the circuit sized to protect the fan motor; or, - being capable of sustaining operation with a locked rotor for 7 h without generating surface temperatures in excess of 150 “C at an ambient temperature of 60 “C, and without evidence of charring, burning or melting. 6 Fan rating 6.1 Fans shal
43、l be rated electrically in volts and in amperes or watts. 6.2 Values for the fan rating, given in cubic metres per second, shall be plotted using the methods given in any of the relevant standards indicated. NOTE 2 References have been given to some national standards concerning tests for ratings, w
44、hich the future IS0 5801 will incorporate, replacing the national standards. 6.2.1 Fans with free inlet, ducted outlet (category B), see the following standards: - AMCA 210-85lASHRAE 51:1985, Figures 9 to 12; - BS 848-1, Figure 27a), Figure 27b), Figure 27c) and Figure 27d); - DIN 24163-1, Bild 1, P

NOTE 3 Fans with free inlet and free outlet (category A) are not used in s
48、mall craft. 6.3 The procedure for rating a fan is as follows. Mount the fan to be tested making certain that all mating surfaces are sealed. Run the fan at 120 % of nominal voltage for a break-in period of 3 h prior to testing. Maintain the fan operating voltage at its nominal voltage throughout the
49、 test. Correct the airflow readings taken during the test to a standard density of 1,2 kglm3. Vary the total pressure in sufficient steps to develop a performance curve. 7 Marking 7.1 Fans shall be permanently and legibly marked with at least the following information: a) manufacturers or private labellers name or trademark b) model or type identification; c) year of manufacture (may be coded); d) electrical rating in volts and amperes or alternatively in volts and watts. 7.2 Evidence of compliance with this International Standard shall be indicated by
