Draft Amendment to C22.1

Replacement:

This part of IEC 62841 applies to rechargeable battery-powered motor-operated chain saws for tree service, hereinafter referred to as chain saws or machines, having a maximum mass of 5,0 kg. The mass includes the heaviest detachable battery pack(s), if any, as described in IEC 62841-1:2014, K.8.14.2 e) 2), but excludes the guide bar, saw chain and saw chain lubricant. Chain saws covered by this document are intended to be used for pruning and dismantling standing tree crowns.

The chain saws covered by this document are designed only to be operated with the right hand on the rear handle and the left hand on the front handle.

This document does not apply to

–   chain saws supplied by mains power or power from non-isolated sources that permit the machine to be used while connected to such power supplies; or

–   chain saws supplied by integral batteries; or

–   chain saws for cutting wood as covered by IEC 62841-4-1; or

–   chain saws designed for use in conjunction with a guide-plate and riving knife or in any other way such as with a support or as a stationary or transportable machine; or

–   pole-mounted pruners; or

  NOTE 1 Pole-mounted pruners are covered by IEC 62841-4-10.

–   pruning saws.

  NOTE 2  Pruning saws will be covered by a future part of IEC 62841-4.

The maximum rated voltage for machines and battery packs is 75 V d.c.

Battery machines covered by this document are not considered to be class I tools, class II tools or class III tools and therefore are not required to have basic insulation, supplementary insulation or reinforced insulation. Electric shock hazard is considered to exist only between parts of opposite polarity.

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.

When evaluating a rechargeable 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 rechargeable 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 rechargeable 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 rechargeable batteries are addressed in this document, such that the requirements of IEC 62133-1:2017 or IEC 62133-2:2017 are not required to be separately applied.

When evaluating the risk of fire associated with rechargeable battery packs for machines, 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.

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.

NOTE 3  IEC 62281:2019 covers the safety aspects of lithium-ion batteries during transport.

– 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 regard 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 document does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the "specified operating region" for a cell. There can be several sets of specified operating region(s).

This document does not apply to machines using general purpose batteries installed by the user and this document alone will not be sufficient to ensure that all hazards are considered for these products.

This document does not apply to the safety of battery chargers themselves.

NOTE 4  IEC 60335-2-29 covers a variety of chargers.

IEC 62841-1:2014, Clause 1 is applicable, except as follows.

Addition:

This document applies to transportable belt sanders, disc sanders and belt/disc sanders which are equipped with

– a sanding belt; or

– a sanding disc; or

– a sanding belt and a sanding disc

for sanding solid materials.

This document does not apply to hand-held disc-type sanders.

CSA Scope

201.1.1 *Scope

[Add the following paragraph]

This Standard applies to ME EQUIPMENT and ME SYSTEMS that are intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code, Part I.

ISO/IEC Scope

IEC 60601-1:2005+AMD1:2012+AMD2:2020, Clause 1, applies, except as follows:

201.1.1   Scope

Replacement:

NOTE 1 There is guidance or rationale for this subclause contained in Clause AA.2.

This document applies to the basic safety and essential performance of ventilatory support equipment, as defined in 201.3.302, for ventilatory insufficiency, as defined in 201.3.302, hereafter also referred to as ME equipment, in combination with its accessories:

— intended for use in the home healthcare environment;

NOTE 2 In the home healthcare environment, the supply mains driving the ventilatory support equipment is often not reliable.

NOTE 3 Such ventilatory support equipment can also be used in professional health care facilities.

— intended for use by a lay operator;

— intended for use with patients who have ventilatory insufficiency or failure, the most fragile of which would likely experience injury with the loss of this artificial ventilation;

— intended for transit-operable use; and

— not intended for patients who are dependent on artificial ventilation for their immediate life support.

EXAMPLE 1

Patients with moderate to severe chronic obstructive pulmonary disease (COPD), moderate amyotrophic lateral sclerosis (ALS), severe bronchopulmonary dysplasia or muscular dystrophy.

Ventilatory support equipment is not considered to use a physiologic closed-loop control system unless it uses a physiological patient variable to adjust the artificial ventilation therapy settings.

This document is also applicable to those accessories intended by their manufacturer to be connected to the ventilator breathing system of ventilatory support equipment for ventilatory insufficiency, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilatory support equipment for ventilatory insufficiency.

EXAMPLE 2

Breathing sets, connectors, water traps, expiratory valve, humidifier, breathing system filter, external electrical power source, distributed alarm system.

If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant.

Hazards inherent in the intended physiological function of ME equipment or ME systems within the scope of this document are not covered by specific requirements in this document except in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.

NOTE 4 Additional information can be found in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 4.2.

NOTE 5 See ISO/TR 21954 for guidance on the selection of the appropriate ventilator for a given patient.

This document does not specify the requirements for:

— ventilators or accessories for ventilator-dependent patients intended for critical care applications, which are given in ISO 80601-2-12;

— ventilators or accessories intended for anaesthetic applications, which are given in ISO 80601-2-13;

— ventilators or accessories intended for the emergency medical services environment, which are given in ISO 80601-2-84;
