28、RODUCTION The concept of safety is closely related to safeguarding the integrity of people and property. This part of IEC 60086 specifies requirements and tests for primary batteries with aqueous electrolyte and has been prepared in accordance with ISO/IEC guidelines, taking into account all relevan
29、t national and international standards which apply. Also included in this standard is guidance for appliance designers with respect to battery compartments and information regarding packaging, handling, warehousing and transportation. Safety is a balance between freedom from risks of harm and other
30、demands to be met by the product. There can be no absolute safety. Even at the highest level of safety, the product can only be relatively safe. In this respect, decision-making is based on risk evaluation and safety judgement. As safety will pose different problems, it is impossible to provide a se
31、t of precise provisions and recommendations that will apply in every case. However, this standard, when followed on a judicious “use when applicable“ basis, will provide reasonably consistent standards for safety. blank 7 PRIMARY BATTERIES Part 5: Safety of batteries with aqueous electrolyte 1 Scope

If encapsulation is necessary to support cells within an outer case, the type of encapsulant and the method of encapsulation shall not cause the battery to overheat during normal operation nor inhibit the operation of the pressure relief feature. The batter
