This standard covers the design, performance, and safety of battery management systems.  Battery management systems are electronic or electromechanical systems that control or regulate a battery or batteries which may include external communication capabilities.

This standard covers battery management systems in all applications including stationary batteries (e.g. local energy storage, smart grids, auxiliary power systems), batteries used to power mobility applications (e.g. electric vehicles, rail transport, aeronautics), and appliances and machinery (e.g. tools, kitchen appliances, manufacturing lines) used in consumer/residential, commercial, and industrial settings.

1.1
This Standard applies to enclosed and dead-front switches for use in photovoltaic (PV) systems rated 1500 V dc maximum, 1200 A maximum.

1.2
Fusible switches for photovoltaic applications are intended for use with photovoltaic fuses covered by CSA C22.2 No. 248.19.

1.3
General requirements applicable to this Standard are given in the latest edition of CAN/CSA-C22.2 No. 0.

1.4
This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 4, which specifies additional mandatory requirements.

1.5
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.1.1 Equipment included in scope 

Replacement: 

Replace the existing text with the following: 

This part of IEC 61010 specifies safety requirements for electrical equipment intended for sterilization, washing, and disinfection of medical materials in the medical, veterinary, pharmaceutical and laboratory fields, when used under the environmental conditions of 1.4. 

Examples of such equipment include the following: 
a) STERILIZERS and disinfectors using steam and/or hot water as the sterilant; 
b) STERILIZERS and disinfectors using toxic gas, toxic aerosol or toxic vapour as the sterilant; 
c) STERILIZERS and disinfectors using hot air or hot inert gas as the sterilant; and 
d) WASHER-DISINFECTORS. 

1.1.2 Equipment excluded from scope 

Addition: 

Add the following note to item f): 

NOTE IEC 60601-1:2005, 3.63, defines "medical electrical equipment" as follows (notes to entry are omitted): 

Electrical equipment, having an applied part or transferring energy to or from the patient or detecting such energy transfer to or from the patient and which is: 

a) provided with not more than one connection to a particular supply MAINS; and 
b) intended by its manufacturer to be used: 
       1) in the diagnosis, treatment, or monitoring of a patient; or 
       2) for compensation or alleviation of disease, injury or disability. 
Addition: 

Add the following new second paragraph after the lettered list: 

This document does not apply to the following types of equipment: 

aa) equipment for use in hazardous atmospheres (see IEC 60079); however this document does apply to an atmosphere created inside equipment by a flammable sterilizing  agent (see 13.2.101 and 13.2.102); 
bb) laboratory equipment for the heating of materials for purposes other than sterilization or disinfection (see IEC 61010-2-010);
cc) laundry equipment (see IEC 60335-2-4, IEC 60335-2-7, IEC 60335-2-11, and ISO 10472 (all parts)), unless designed for disinfecting medical materials;
dd) dishwashers (see IEC 60335-2-5 and IEC 60335-2-58). 

1.2.1 Aspects included in scope 

Replacement: 

Replace item g) with the following new text: 

g) liberated gases (including the non-intentional escape of toxic gas), pathogenic 
substances, explosion and implosion (see Clause 13).  

1.2.2 Aspects excluded from scope 

Addition: 

Add the following two new items: 

aa) special requirements for protection against chemical and high-risk micro-biological HAZARDS associated with the LOAD; 
bb) general requirements for the design of calorifiers, shell boilers and PRESSURE VESSELS. 

NOTE National and other regulations or codes apply for the safety of calorifiers, shell boilers and  PRESSURE VESSELS (see 14.101).
