40 PARTICULAR REQUIREMENTS
42 FOREWORD
43 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
44 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
45 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
46 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
47 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
48 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
49 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
50 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
51 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
52 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
53 consensus of opinion on the relevant subjects since each technical committee has representation from all
54 interested IEC National Committees.
55 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
56 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
57 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
58 misinterpretation by any end user.
59 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
60 transparently to the maximum extent possible in their national and regional publications. Any divergence between
61 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
62 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
63 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
64 services carried out by independent certification bodies.
65 6) All users should ensure that they have the latest edition of this publication.
66 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
67 members of its technical committees and IEC National Committees for any personal injury, property damage or
68 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
69 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
70 Publications.
71 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
72 indispensable for the correct application of this publication.
73 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
74 rights. IEC shall not be held responsible for identifying any or all such patent rights.

110 INTRODUCTION
111 It has been assumed in the drafting of this International Standard that the execution of its
112 provisions is entrusted to appropriately qualified and experienced persons.
113 This standard recognizes the internationally accepted level of protection against hazards such
114 as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
115 use taking into account the manufacturer's instructions. It also covers abnormal situations that
116 can be expected in practice and takes into account the way in which electromagnetic
117 phenomena can affect the safe operation of appliances.
118 This standard takes into account the requirements of IEC 60364 as far as possible so that there
119 is compatibility with the wiring rules when the appliance is connected to the supply mains.
120 However, national wiring rules may differ.
121 This standard is a product family standard dealing with the safety of appliances and takes
122 precedence over horizontal and generic standards covering the same subject.
123 NOTE Horizontal and generic standards covering a hazard are not applicable since they have been taken into
124 consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
125 example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
126 ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
127 An appliance that complies with the text of this standard will not necessarily be considered to
128 comply with the safety principles of the standard if, when examined and tested, it is found to
129 have other features that impair the level of safety covered by these requirements.
130 An appliance employing materials or having forms of construction differing from those detailed
131 in the requirements of this standard may be examined and tested according to the intent of the
132 requirements and, if found to be substantially equivalent, may be considered to comply with the
133 standard.

383 It shall only be possible to start the type 2 machine in automatic mode from initial start-up by
384 intended actuation of an access control provided for the purpose or via a supervisory
385 function. This requirement does not apply when restarting the type 2 machine in automatic
386 mode after a stop category 0 or stop category 1, unless it is is triggered based on a detected
387 failure in the safety-related parts of the control system per clause 7.8. This requirement only
388 applies to components where the unexpected starting might cause a hazard. It does not apply
389 to components such as suction units, pumps, etc.
390 Compliance is checked by inspection and test.
391 7 Stability and mechanical hazards
392 7.1 Machines in automatic mode, operating in an open space environment, shall not exceed
393 6 km/h. Machines in automatic mode operating in a confined space environment shall not
394 exceed 4 km/h.
395 NOTE 1 As specified in this standard, manual mode speed can be higher than automatic mode speed.
396 Compliance for machine speed operating in confined space environment is checked by
397 measurement in accordance with the test procedure as described below.
398 The test area of the confined space environment consists of two continuous walls or obstacles,
399 each with a minimum length equal to the machine transport length and a minimum height of 1
400 m. One wall is located on one side of the machine, and the other wall is located on the opposite
401 side of the machine starting from the location where the first wall ends. The two walls are placed
402 in the direction of travel of the machine so that they are within the confined space distance on
403 each side from the machine transport width. Sensors are allocated at each end of the test
404 area to measure the start and finish of the machine traversal.
405 NOTE 2 An example of test set up is shown in Figure 1.
406 The machine, loaded to the GVW rating, traverses towards the confined space test set-up area
407 at the maximum open space speed and enters the confined space test area. The confined
408 space speed is measured from the start and end of the machine traversal through the confined
409 space test set-up area. The average speed shall be measured over three successful speed
410 measurements.
411 Compliance is checked by measurement in accordance with ISO 18646-1:2016, Clause 5, with
412 the machine loaded to the GVW rating.
413 7.2 Machines that can function in manual mode as ride-on machine or a walk-behind
414 machine with traction drive shall not be possible to operate with the higher speed of manual
415 mode when operating in automatic mode.
416 Compliance is checked by inspection and measurement.
417 7.3 The detection system shall be capable of avoiding hazardous contact with obstacles in
418 the directions in which the machine is capable of motion at distances greater than S , as
a
419 calculated in 0, for the maximum speed the machine can travel in that direction. In case a
420 bumper system is applied, additional requirements apply as given in normative Annex KK. This
421 requirement is not applicable to type 1 machines not exceeding a speed of 1,5 km/h and to
422 automatic floor treatment machines during the docking process to the docking station.
IEC CDV 63327 © IEC 2026
423 The maximum allowed stopping distance, Sa, shall be calculated using the following formula:
424 S < 1,2 × V
a a
425 where
426 S is stopping distance in automatic mode (m);
a
427 V is maximum rated automatic speed of the machine in the direction of test (m/s).
a
428 NOTE Stopping distance is based on a reaction time below 0,5 s.
429 Compliance is checked by functional test.
430 Obstacles according 5.1 shall be used for testing.
431 Compliance is checked by functional test.
432 7.4 A machine shall not fall over abrupt surface elevation changes such as staircases,
433 unprotected drop-offs, and the like.
434 Compliance is checked by the following test: The machine shall be tested on a surface
435 (11 ± 1) cm above an adjacent surface. The lower surface shall be a minimum 1 m in length
436 from where it meets the upper surface; the lowest surface is concrete. The test shall be
437 conducted under the most unfavourable conditions, based on sensor positions, both starting
438 from rest and in motion towards the abrupt surface elevation change under normal operation
439 and at loaded to the GVW rating.
440 The machine shall be able to detect and stop in the presence of abrupt surface elevation
441 changes of (11 ± 1) cm or greater in all directions of travel.
442 7.5 The control system of safety-critical functions in the machine (i.e., electric, hydraulic,
443 pneumatic, and software) shall be designed so that they comply with the PL levels and
444 structures as described in ISO 13849-1. The tests of 7.1 to 7.4 and 7.6 to 7.10 shall be
445 conducted using only the control system of the safety-critical functions which meet the
446 requirements of 7.6.
447 Recommended performance level required PLr according to ISO 13849-1 for type 1 machines,
448 type 2 machines, and machines with bumper system and the correlation to required safety
449 integrity level, under IEC 62061, achieving the required risk reduction are given in normative
450 Annex J under Table JJ.1 and Table JJ.2.
451 7.6 In the initial start-up state, while the machine is at rest, each of the obstacles described
452 in 5.1 is placed in turn in contact with the machine at various locations representative of the
453 contact zone. The machine shall not initiate motion unless after selection of automatic mode
454 by an operator the machines moves directly away from the obstacle.
455 The machine shall not initiate motion, unless
456 – it moves directly away from the obstacle after automatic mode is initiated by the
457 operator, and
458 – it can determine that nothing is in the contact zone, through guards or sensing, in the
459 direction of motion without contacting the obstacle.
460 NOTE: an initial contact with the obstacle  50N is considered to be acceptable.
461 This requirement is not applicable to type 1 machines not exceeding a speed of 1,5 km/h and
462 to automatic floor treatment machines during the docking process to the docking station.
IEC CDV 63327 © IEC 2026
463 Compliance is checked by functional test. Test duration is 5 min or less if the machine moves
464 away from the obstacle.
465 7.7 An automatic restart (replacing operator intervention directly at the machine) after a
466 stop category 0 or stop category 1 shall be possible. In case the restart is conducted via
467 remote communication, this shall be done by applying the supervisory function, for which
468 remote operation shall be enabled. The obstacle test conditions of clause 7.6 shall be met for
469 an automatic restart. An automatic restart shall not be possible after a stop category 0 or stop
470 category 1 is triggered based on a detected failure in the safety-related parts of the control
471 system per clause 7.8.
472 Compliance is checked by the following:
473 7.8 The tests of this standard shall be performed after disabling remote operation unless a
474 supervisory function is applied, where for the restart testing the remote operation shall be
475 enabled. The machine shall monitor the operating status of all safety-related control parts of
476 the control system before starting and during operation.
477 Any detected failure in the safety-related parts of the control system shall result in a stop
478 category 0 or stop category 1 with the driving wheels in a locked state. The machine shall
479 require the intervention of the operator to restart.
480 The safety-related parts of the control system are the relevant parts of the safety-critical
481 functions (SCFs) identified inTable JJ.1.
482 Compliance is checked by an evaluating system in accordance with Table JJ.1.
483 7.9 The machine shall avoid any hazardous contact with any static objects that enter the
484 stopping zone. When any obstacle described in 5.1 enters the stopping zone, at least a stop
485 category 2 or obstacle avoidance shall be initiated. This requirement is not applicable to type
486 1 machines not exceeding a speed of 1,5 km/h and to automatic floor treatment machines
487 during the docking process to the docking station.
488 When a stop category 2 is achieved and the machine is at rest, the contact zone sensors may
489 be disabled.
490 NOTE When the obstacle is removed, the machine can resume movement automatically unless contact with the
491 obstacle is made.
492 Compliance is checked by the following test:
493 The machine is driven toward the test obstacles, at both confined space speed and rated
494 automatic speed. The obstacles are placed outside of the stopping zone ahead of the
495 machine. The machine shall avoid contact with any objects when entering the stopping zone.
496 When any obstacle described in 5.1 enters the stopping zone, at least a stop category 2 or
497 obstacle avoidance shall be initiated. Each obstacle shall be tested separately. Test obstacle 1
498 shall be laying down and at 0°, 45°, and 90° to the path of the machine, at a range greater than
499 the machine safe stopping distance and positioned at the left-most (one-half the width of the
500 machine from the centreline), right-most, and centre of the machine travel path. Test obstacle
501 2 shall be set vertically at a range equivalent to the machine safe stopping distance and
502 positioned at the left-most, right-most, and centre of the machine path (see Figure 2 for obstacle
503 positioning).
504 7.10 Following a stop category 2, each of the obstacles described in 5.1 is placed in contact
505 with the machine at various locations representative of the contact zone. The machine shall
506 not initiate motion, unless the system ensures during motion to brake on time to prevent further
507 contact with the obstacle. This requirement is not applicable to type 1 machines not exceeding
508 a speed of 1,5 km/h and to automatic floor treatment machines during the docking process
509 to the docking station.
IEC CDV 63327 © IEC 2026
510 NOTE: an initial contact with the obstacle  50N is considered to be acceptable.
511 Compliance is checked by functional test. Test duration is 5 min or less if the machine moves
512 away from the obstacle.
513 7.11 When either of the obstacles described in 5.1 enters the contact zone while the machine
514 is moving, a stop category 0 or stop category 1 shall be initiated. This requirement is not
515 applicable to type 1 machines not exceeding a speed of 1,5 km/h and to automatic floor
516 treatment machines during the docking process to the docking station.
517 Compliance is checked by the following test:
518 The obstacle is moved in front of the machine’s direction of motion inside the stopping zone.
519 The machine’s contact zone shall initiate a stop category 0 or stop category 1, due to
520 anticipated contact with the obstacle.
