  • c) TR03 and TR6 were added in Category 1, Round batteries;
  • d) load of digital audio test for LR03, TR03 and R03 was changed from 50 mA to 75 mA and MAD was modified;
  • e) personal grooming test of LR6 was added instead of high drain application test;
  • f) high drain application test was added for TR6;
  • g) radio /clock /remote control test was added for R6S;
  • h) CD, digital audio, wireless gaming and accessories test was removed for LR6, R6P and R6S;
  • i) 4,5 V of common designation was added for 3LR12, 3R12P and 3R12S;
  • j) Annex D for common designation of IEC 60086 2:2021 was moved to IEC 60086 1:2026, as Annex H;
