The BSI project describes BS EN 3-11:2026 as supplementing EN 3-7 with test-method and marking requirements for extinguishers intended for fires in small rechargeable lithium-ion batteries.

What do we check?

Each update should verify the designation, development or publication stage and national adoption. A project number, a published standard and a document for an individual product are not interchangeable. Polish adoption requires a separate check.

Questions before purchasing

  • Which edition does the document cite?
  • Which model and configuration does the report cover?
  • What are the test conditions and limitations?
