The work of preparing International S
3、tandards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, a
4、lso take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

6、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, which the future IS0 5801 will incorporate, replacing the national stan- dards. 6.2.1 Fans with free inlet, duct

9、1, figures 29 a) to e); - DIN 24163-2, Bild 4. NOTE 3 Fans with free inlet and free outlet (category A) are not used in small 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 voltag
10、e for a break-in period of 3 h prior to testing. Maintain the fan operating voltage at its nominal voltage throughout the test. Correct the airflow readings taken during the test to a standard density of I,2 kg/ms. Vary the total pressure in sufficient steps to develop a performance curve. 2 Copyrig
