water-suction cleaning
– 4 – 60335-2-79 Amend. 1 IEC:2004(E)
7.12 Add the following dashed items and additional paragraphs:
– the A-weighted sound pressure level L in dB(A), emitted by the appliance. If the A
pA
weighted sound pressure level exceeds 85 dB(A), it shall also state the sound power level
L in dB(A) and that appropriate ear protection has to be used. The sound level is
WA
measured in accordance with IEC 60704-1;
– the weighted r.m.s. acceleration value to which the operators’ arms are subjected in m/s²,
separately for each arm (if applicable). The weighted r.m.s. acceleration value is
measured in accordance with ISO 5349 for arm vibrations, the appliance being supplied at
rated voltage or at the maximum rated voltage for machines with a range of voltages.
The instructions for appliances having a current-carrying hose operating at other than safety
extra-low voltage shall include the substance of the following:
CAUTION: This hose contains electrical connections:
– do not use to collect water;
– do not immerse in water for cleaning;
– the hose should be checked regularly and must not be used if damaged.
If the symbol IEC 60417-5935 is used, its meaning shall be explained.
7.14 Addition:
The height of symbol IEC 60417-5935 shall be at least 15 mm.
Compliance is checked by measurement.
7.101 Motorized cleaning heads shall be marked with
– rated voltage or rated voltage range in volts;
– rated power input in watts;
– name, trade mark or identification mark of the manufacturer or responsible vendor;
– model or type reference.
Motorized cleaning heads for water-suction cleaning appliances, except those of class III
construction having a working voltage up to 24 V shall be marked with symbol IEC 60417-
5935.
