Understanding CO2 Cylinder Marking

I had recently acquired a CO2 cylinder which has the below marking and after some on-line research I found that the meaning is as follows:

CO2 - 2 TP250 V3.0 W6.13 BXXXX XXX 2011/03

Marking Meaning:

CO2-2: Filling gases - Carbon Dioxide 

TP250: Test pressure - 25MPA 

V3.0: Volume - 3.0L 

W6.1: Weight - 6.1KG 

BXXXX XXX: Product No.

2011/03:  Hydrostatic Test Date - CO2 cylinders needs hydrostatic testing every 5 years
