AS/NZS 60335.2.69:2017 pdf free.Household and similar electrical appliances – Safety Part 2.69: Particular requirements for wet and dry vacuum cleaners, including power brush, for commercial use.
P and P are measured with the supply voltage adjusted to rated voltage, or to a voltage equal to the mean value of the rated voltage range if the difference between the limits of the rated voltage range does not exceed 10% of the mean value of the range. If the difference between the limits of the rated voltage range exceeds 10 % of the mean value, the tests are carried out with the supply voltage set to the upper limit of the range.
The measurements are made with the machine fitted with a clean dust bag and filter and with the water container, if any, empty. It the machine is intended for use only with a hose, detachable nozzles are removed and the hose is laid out straight. If the machine is provided with a hose as an optional accessory, it is operated without the hose.
Electrically driven devices, if any, are in operation but are not in contact with the floor or any other surface or with the means used to seal the air inlet.
The normal load is equal to the mean load P, for the electrically driven agitating device such as a motor driven brush determined in accordance with the following:
— the agitating device operates on a carpet as specified in lEG 60312-1;
— the mean load P. is determined when using the device in the following way:
After setting the device, the device is moved twice over a distance of 5 m in the direction giving the highest load;
— the motor responsible for the airflow operates under the same conditions as for determining Pf, i.e. no airflow restrictions, and measurements are taken after 3 mm;
— the device is adjusted to the carpet pile height;
— it is necessary to move the agitating device slowly across the carpet to avoid carpet damage.
Soiled water discharge pumps. if applicable, are operated as follows.
The pump delivers a continuous flow of water without any soiled water discharge hose attached to the soiled water outlet of the machines unless the discharge hose is permanently attached to the machine. The vacuum motor works during the test, unless an interlock device is provided to prevent combined operation of both motors.
Machines equipped with an inflating function are also operated whilst equipped with the hose as described in the instructions for use. The hose is placed in a straight line away from the machine. Power adjustment controls are set to the highest input power.
Machines equipped with a blowing function are also operated whilst equipped with the two hoses or as described in the instructions for use. Both hoses are placed in a straight line away from the machine. Power adjustment controls are set to the highest input power. The blowing hose is not equipped with any attachments, e.g. nozzles.
