The permissible sound power level shall be rounded up or down to the nearest integer number (less than 0.5, use lower number; greater than or equal to 0.5, use higher number).
a P_el for welding generators: conventional welding current multiplied by the conventional load voltage for the lowest value of the duty factor given by the manufacturer. P_el for power generators: prime power according to ISO 8528-1:1993, clause 13.3.2.
b For the following types of equipment the figures for Stage I shall continue to apply for Stage II— Walk-behind vibrating rollers; Vibratory plates (>3 kW); Vibratory rammers; Dozers (steel tracked); Loaders (steel tracked >55 kW); Combustion-engine driver counterbalanced lift trucks; Compacting screed paver-finishers; and Hand-held internal combustion-engine concrete-breakers and picks (15< m<30).
c For single engine mobile cranes the figures for Stage I shall continue to apply until 3rd January 2008. After that date, Stage II figures shall apply.
