3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-482, ISOIIEC Guide 51, and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1 safety freedom from unacceptable risk
3.2 ri 8k combination of the probability of occurrence of harm and the severity of that harm
4 Parameter measurement tolerances
The overall accuracy of controlled or measured values, relative to the specified or actual parameters, shall be within the following tolerances:
a) +0,5 % for voltage,
b)+1% for current;
c) +2 °C for temperature;
d) +0,1 % for time;
e)+1% for mass;
f)+1% for dimensions.
These tolerances comprise the combined accuracy of the measuring instruments, the measurement techniques used, and all other sources of error in the test procedure.
The details of the instrumentation used shall be provided in any report of results.
5 General safety considerations
5.1 General
Battery systems and the cells they contain shall comply with the applicable general safety considerations of IEC 62619. Within the standard temperature range, secondary cells can be charged at the maximum charge current, which is specified from a safety point of view. Lithium-Ion cells shall always be operated within the operating region values and the storage conditions specified by the manufacturer.
The safety of lithium secondary cells and battery systems requires the consideration of two sets of applied conditions:
1) intended use;
2) reasonably foreseeable misuse
Cells and battery systems shall be so designed and constructed that they are safe under conditions of both intended use and reasonably foreseeable misuse. It may also be expected that cells and battery systems subjected to intended use shall not only be safe but shall continue to be functional in all respects.
It is expected that cells or battery systems subjected to misuse may fail to function. However, even if such a situation occurs, they shall not present any significant hazards.
Potential hazards which are the subject of this document are:
a) fire.
b) burst/explosion,
c) critical electrical short circuit due to leakage of cell electrolyte, mechanical deformation or incorrect installation,
d) venting that continuously vents out flammable gases,
e) rupture of the casing of cell, module, battery pack, and battery system with exposure of internal components.
Conformity is checked by the tests In accordance with the appropriate standards in Clause 2.IEC 63056 pdf free download.
