25、17ISO 9097:1991(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subj
26、ect for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IE
27、C) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.International Standa

Fan airflow shall be measured in
36、accordance with clause 6, and performance curves shall 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 p
37、rotection against injury. Enclosures shall be provided 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. 4.6 Fans shall be provided with a means for securely mounting the

39、ailable for each fan (see 6.2). 5 Electrical requirements5.1 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 s
40、pecify requirements for extra-low-voltage electrical installations.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. 5.4 If external motor leads are provided with the fan, they shal
41、l be sized in accordance with the power requirement but not 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 in
42、tegral overcurrent protection; or, overcurrent protection 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 charrin

48、ughout the test.Correct the airflow readings taken during the test to a standard density of 1,2 kg/m3.Vary the total pressure in sufficient steps to develop a performance curve. 7 Marking7.1 Fans shall be permanently and legibly marked with at least the following information: a) manufacturers or pri
