IEC 63327-2021 pdf free download – Automatic floor treatment machines for commercial use — Particular requirements.
4General requirements
The machine shall be constructed as follows;
The machine when in manual mode shall fulfil the requirements for commercial floortreatment machines according to IEC 60335-2-72:2021 unless stated otherwise in thisstandard.Further requirements for the automatic mode are given within the main body of thisstandard. Machines shall be constructed in their manual and automatic mode so that theyfunction safely to cause no danger to persons or surroundings during normal use,even in theevent of carelessness,and during installation,adjusting, maintenance, cleaning,repairing, ortransportation. For ride-on machines in automatic mode,operator presence on” themachine shall be prevented either by sensing which stops the machine from operating,ordesign features which prevent operator presence.
Modified requirements to lEc 60335-2-72:2021 are given in normative Annex FF of thisstandard for automatic floor treatment machines not equipped with a manual mode.
For the purposes of this standard, the term ‘appliance’as used in lEC 60335-1:2020 is to beread as ‘machine”_
Safety of the machine shall not depend on remote operation.Resetting of stop category o orstop category 1 shall not be possible remotely.
Compliance is checked by the following:
The tests of this standard shall be performed after disabling remote operations.
5General conditions for the tests
5.1 The following test obstacles, taken from ISO 13856-3,shall be covered in black felt orcoarse fabric with a reflectance between 5 %and 10 %:
a)Obstacle 1 – a cylinder with a diameter of 200 mm and a length of 600 mm，placedhorizontally; and
b) Obstacle 2 – a cylinder with a diameter of 70 mm and a height of 400 mm, placed
vertically.
NOTE To perform the test， the obstacle can be attached to a flat plate with a handle or a cord can be used toplace the obstacle.
5.2 Tests shall be conducted at lighting level between 100 lx and 1000 lx.
6Starting of motor operated appliances
lt shall only be possible to start the type 2 machine in automatic mode from initial start-upby intended actuation of an access control provided for the purpose. The same requirementapplies when restarting the type 2 machine in automatic mode after a stop category 0.Thisrequirement only applies to components where the unexpected starting might cause a hazard.lt does not apply to components such as suction units, pumps,etc.
Compliance is checked by inspection and test.
7 Stability and mechanical hazards
7.1 Machines in automatic mode，operating in an open space environment,shall notexceed 6 km/h. Machines in automatic mode operating in a confined space environmentshall not exceed 4 km/h.
NOTE 1 As specified in this standard, manual mode speed can be higher than automatic mode speed.
Compliance for machine speed operating in confined space environment is checked bymeasurement in accordance with the test procedure as described below.
The test area of the confined space environment consists of two continuous walls orobstacles, each with a minimum length equal to the machine transport length and a minimumheight of 1 m.One wall is located on one side of the machine,and the other wall is located onthe opposite side of the machine starting from the location where the first wall ends. The twowalls are placed in the direction of travel of the machine so that they are within the confinedspace distance on each side from the machine transport width. Sensors are allocated ateach end of the test area to measure the start and finish of the machine traversal.
NOTE 2 An example of test set up is shown in Figure 1.
The machine，loaded to the Gvw rating,traverses towards the confined space test set-uparea at the maximum open space speed and enters the confined space test area.Theconfined space speed is measured from the start and end of the machine traversal throughthe confined space test set-up area. The average speed shall be measured over threesuccessful speed measurements.
Compliance is checked by measurement in accordance with lSO 18646-1:2016,Clause 5,with the machine loaded to the Gvw rating.
7.2 Machines that can function in manual mode as ride-on machine or a walk-behindmachine with traction drive shall not be possible to operate with the higher speed of manualmode when operating in automatic mode.
Compliance is checked by inspection and measurement.IEC 63327 pdf download.
