Something Informative

On one of three vertical stay plates (side stems) of the LPG cylinder, the date is coded alpha numerically as A or B or C or D and a two-digit number following this e.g. D10. The alphabets stand for quarters – A for Qtr. ending March (First Qtr), B – Qtr. ending June (Second Qtr), C-Qtr. ending Sept (Third Qtr), & D for Qtr. ending December (Fourth Qtr). The digits stand for the year when the cylinder is due for Statutory testing as explained above. Hence D10 would mean that the particular cylinder is to be taken for the next Statutory Testing by December 2010.
In any case, this is not the date of EXPIRY of PHYSICAL LIFE of the CYLINDER
It is further clarified that, during service, every empty LPG cylinder when it comes from the Distributor to the Bottling Plant for filling, is checked for its condition including the marked date for Statutory Testing due. Cylinders due for testing are segregated and sent for testing.

Every cylinder after its filling with LPG is checked for correctness of its weight and soundness, before despatch to the Distributors. Every care is taken to ensure that cylinders which are safe for use are only sent to our Distributors for further distribution. It means if a customer gets a cylinder in June 2010 with marking as B10, it does not indicate that the physical life of the cylinder has expired. It only means that this cylinder is due for Statutory testing by end June 2010.
