What is BS EN IEC 60086‑1 about?
BS EN IEC 60086‑1 is intended to standardize primary batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, typical performance, safety, and environmental aspects.
BS EN IEC 60086‑1 specifies system letters, electrodes, electrolytes, and nominal as well as the maximum open-circuit voltage of electrochemical systems, as a classification tool for primary batteries.
NOTE 1: BS EN IEC 60086‑1 also contains requirements justifying the inclusion of the ongoing retention of batteries in the IEC 60086 series.
Who is BS EN IEC 60086‑1 for?
BS EN IEC 60086‑1 on primary batteries is for:
- Manufacturers of primary batteries such as alkaline battery, lead-acid battery
- Suppliers and dealers of primary batteries
- Importers of primary batteries
- Device designers for primary batteries
- Service providers for primary batteries
Why should you use BS EN IEC 60086‑1?
Primary batteries are single-use galvanic cells that store electricity for convenient usage. The objective of BS EN IEC 60086‑1 is to benefit you by ensuring that batteries from different manufacturers are interchangeable according to standard form, fit and function. It specifies requirements for primary cells and batteries, and procedures of how requirements for these batteries are to be standardized.
BS EN IEC 60086‑1 helps ensure compliance with standard test methods for testing primary cells and batteries.
Furthermore, BS EN IEC 60086‑1 specifies standard test methods for testing primary cells and batteries and elements that can be used as classification tools for primary batteries, to enhance the quality of a primary battery.
What’s changed since the last update?
BS EN IEC 60086‑1:2021 supersedes BS EN 60086‑1:2016, which is withdrawn. BS EN IEC 60086‑1:2021 includes the following significant technical changes with respect to the previous edition:
- A compliance checklist was added as an Annex H
- Definitions were harmonized with the other 60086 series documents
- The nominal voltage of the zinc air system is now listed as either 1,4 V or 1,45 V
- Annex F for calculation of MAD values was simplified
- A validity period for testing was added
- The accelerated aging test at 45 °C was changed from 13 to 4 weeks
