1 Scope
1.1 This Standard applies to battery powered appliances. This Standard applies to appliances incorporating detachable battery packs, integral batteries and separable battery packs. This Standard also applies to appliances that can readily accept non-rechargeable general purpose batteries. The maximum rated voltage for appliances, detachable battery packs and separable battery packs is 250V d.c.
NOTE: Although this Standard applies to appliances, this does not restrict referring to this Standard by other end-product category standards that share similarities in battery type and electrical and charging systems to those found in battery powered appliances.
1.2 This Standard also applies to battery powered appliances that are also operated and/or charged directly from the mains or a non-isolated source, including appliances provided with integral battery chargers. The additional considerations for these constructions are contained in Section 23, Additional Requirements for Battery Powered Appliances With a Connection to Mains or a Non-isolated Source.
1.3 These requirements are structured so as to be used in conjunction with an end-product standard. These requirements are not intended to provide comprehensive evaluation of a battery powered appliance independent of an end-product standard.
1.4 These requirements only address the potential risks unique to the utilization of a battery supply in a product. With the exception of appliances that also have a mains or non-isolated source, these requirements replace or modify the requirements associated with risk of fire and electric shock for mains powered versions of the appliance in the end-product standard. See Indent A in .
1.5 Conditions of use of the product that are the basis for test and other evaluations in the standard are retained and applied, as far as practicable, to these products employing a battery supply.
1.6 Battery powered appliances not able to be connected to mains or a non-isolated source are not considered to be Class 0 appliances, Class I (grounded) appliances or Class II (double insulated) appliances and therefore are not required to have basic, supplementary or reinforced insulation. Electric shock hazard is considered to exist only between parts of different potential.
1.7 When evaluating the risk of fire associated with batteries, consideration has been given to the fact that these batteries are unattended energy sources and have been evaluated as such in this Standard. Batteries evaluated by this Standard are therefore considered to fulfill an effective protection against the risk of fire equivalent to that of the end-product standard.
1.8 Since batteries for appliances are subjected to different use patterns (such as rough use, high charging and discharging currents) their safety cannot be comprehensively evaluated only using standards for batteries, such as UL 1642, UL 2054, IEC 62133-2, UL 62133, UL 62133-1, UL 62133-2 and CSA C22.2 No. 62133, CSA C22.2 No. 62133-1, CSA C22.2 No. 62133-2 and needs to be evaluated to the broader requirements included in this Standard.
1.9 This Standard does not apply to the safety of battery chargers themselves. However, this Standard covers the safe functioning of lithium-ion battery systems.
1.10 This Standard also addresses requirements covering the use of lithium-ion cells employed in battery systems in appliances. The following is considered within the context of these requirements:
a) These requirements address the risk of fire or explosion of these batteries but do not cover any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.
b) Battery systems covered by these requirements are not intended to be serviced by the end user.
c) These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this Standard.
d) 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).
1.11 This Standard does not apply to appliances using rechargeable general purpose batteries installed by the user, with the exception of lead-acid general purpose batteries for starting, lighting, and ignition (SLI).
1.12 These requirements do not consider the effect of special applications (such as medical appliances) or special environments (such as hazardous locations).
1.13 These requirements have not been assessed for their suitability for product categories other than appliances such as information technology equipment, telecommunications, laboratory equipment, fire alarm, security systems, emergency lighting, and audio-video apparatus, and may be incomplete with respect to those categories.
1.14 These requirements address the safety of battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements with respect to the risk of fire and electric shock in battery chargers. The safety of battery chargers for appliances are covered by other standards such as:
a) UL 1012;
b) UL 1310;
c) UL 1564;
d) UL 60335-2-29;
e) UL 60950-1;
f) UL 62368-1;
g) CSA C22.2 No. 107.2;
h) CSA C22.2 No. 223;
i) CSA C22.2 No. 60335-2-29;
j) CSA C22.2 No. 60950-1; and
k) CSA C22.2 No. 62368-1.
1.15 These requirements make frequent reference to the conditions and tests of the end-product standard while also providing minimum conditions or severity of tests. These minimum conditions are not to be construed to imply equivalence to end-product requirements. Conditions or requirements of end-product standards are to prevail over the conditions or requirements of this Standard, unless otherwise specified in this Standard.
1.16 This Standard is not intended to cover appliances using lithium-metal type cells, and this Standard alone will not be sufficient to ensure all hazards are considered for these types of cells. Lithium-ion cells are not lithium-metal cells.
