The expiry date of an LPG cylinder, also called the resetting date or due date, is printed on the metal stay of the cylinder in the format A/B/C/D–YY, where the letter indicates the quarter (A = Jan–Mar, B = Apr–Jun, C = Jul–Sep and D = Oct–Dec) and YY is the year. For example, B-28 means the cylinder is valid until June 2028; (due for mandatory testing between April and June 2028) after this date, it should not be used until revalidated for safety.
