1.1 General

1.1.1 Purpose

This Standard specifies laboratory test methods and procedures for determining operational performance indicators of Thermal Energy Storage System’s (TESS) used for space heating applications in residential, commercial and institutional buildings.

This standard includes an informative annex to introduce basic building TESS grid services functions, including building TESS equipment communication.

1.1.2 Applicability

a)    This Standard applies to packaged building TESS that can be tested in laboratory environment. The system is either a factory pre-assembled unit or a unit assembled on-site in the laboratory test facility from factory-supplied components.

b)   The TESS is charged electrically and discharged thermally. The energy shall be stored as latent heat or as sensible heat or as a combination of the two.

c)    The TESS is charged by electric-resistance heating, and the electric resistance mechanism is an integral part of or is located inside the TESS.

d)   The TESS is discharged with a heat transfer fluid that enters the system through a single inlet and leaves the system from a single outlet. TESS having more than one inlet and/or outlet shall be tested according to this standard, but each flow configuration involving a single inlet and a single outlet must be tested separately. The heat transfer fluid may be either a non-condensing gas or a liquid.

IEC Scope

This clause of Part 1 is replaced by the following.

This part of IEC 60335 deals with the safety of electric clothes dryers including clothes dryers intended for drying footwear or gloves, and towel rails for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) powered appliances and battery-operated appliances.

Appliances not intended for normal household use but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account:

– persons (including children) whose

• physical, sensory or mental capabilities; or

• lack of experience and knowledge

prevents them from using the appliance safely without supervision or instruction;

– children playing with the appliance.

Attention is drawn to the fact that:

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;

– in many countries, additional requirements are specified by the national health authorities,

the national authorities responsible for the protection of labour and similar authorities.

This standard does not apply to:

– spin extractors (IEC 60335-2-4);

– tumble dryers (IEC 60335-2-11);

– appliances intended exclusively for industrial purposes;

– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

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
