This International Standard deals with the safety of electric motor-operated or magnetically driven rechargeable battery-powered ride-on lawnmowers equipped with
– metallic cutting means; and/or
– rigid non-metallic cutting means; and/or
– non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting
and the battery packs for machinery. The above listed categories are hereinafter referred to as “machines”.
This standard does apply to ride-on lawnmowers that can be operated as stand-on lawnmowers or used in pedestrian-controlled mode.
The maximum rated voltage for machines and battery packs is 250 V d.c.
This document deals with the hazards presented by machines which are encountered by all persons in the normal use and reasonably foreseeable misuse of the machines.
Machines with electric heating elements are within the scope of this document.
When evaluating a battery pack for protection against electric shock during charging, creepage distances, clearances and distances through insulation, the relevant requirements of this document are applicable with the battery pack fitted to the intended charger.
Since battery packs for machines are submitted to different use patterns (such as rough use, high charging and discharging currents) their safety can be evaluated only by this document and not by using other standards for battery packs, such as IEC 62133-1:2017 or IEC 62133-2:2017, unless otherwise indicated in this document. All relevant aspects related to the safety of batteries are addressed in this document, such that the requirements of IEC 62133-1:2017 or IEC 62133-2:2017 need not be separately applied.
When evaluating the risk of fire associated with battery packs, consideration has been given to the fact that these battery packs are unattended energy sources and have been evaluated as such in this document. Requirements in other standards regarding the risk of fire due to the charging of these battery packs are therefore considered to be fulfilled.
Automotive-type charging interfaces are not addressed in this standard.
This document also addresses requirements covering the use of lithium-ion cells employed in battery systems in machines. The following is considered within the context of these requirements:
– These requirements address the risk of fire or explosion of these batteries and not any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.
– Battery systems covered by these requirements are not intended to be serviced by the end user.
– These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this document.
– These requirements address the safety of lithium-ion battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements in regards to battery charger fire and electric shock.
– These requirements refer to and require parameters supplied in reference to the cells that establish conditions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This standard does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the “Specified Operating Region” for a cell. There may be several sets of specified operating region(s).
This document is not intended to apply to machines using general purpose batteries installed by the user and this document alone will not be sufficient to ensure all hazards are considered for these products.
This document does not apply to the safety of battery chargers themselves. However, this document covers the safe functioning of lithium-ion battery systems.
Mains-powered circuits for battery charging, preheating or other non-motor functions are covered under Annex CC.
This document does not apply to
– machines supplied by mains power or power from non-isolated sources that permit the machine to be operated while connected to such power supplies for purposes other than charging;
– pedestrian controlled walk-behind lawnmowers;
– seated or standing sulky attachments;
– robotic battery powered electrical lawnmowers;
– remote-controlled machines;
– flail mowers or flail-type attachments;
– scissors type lawnmowers;
– grassland mowers;
– sickle bar mowers;
– towed/semi-mounted grass-cutting machines;
– scrub-clearing machines;
– lawn trimmers and lawn edge trimmers;
– edgers;
– grass trimmers;
– brush cutters;
– brush saws;
– agricultural machinery or their attachments;
– non-powered lawnmowers;
– combustion engine powered lawnmowers;
– hybrid and fuel cell powered machines and associated charging systems; and
– machines intended to be used in the presence of explosive atmosphere (dust, vapour or gas).
