color coding of LPG cylinder

COLOUR CODING

(a)`      The following five colours have been selected for colour coding of cylinders for the  re-test  due in next five years.  After five years, the same colours can be repeated in the same order:

Cylinder re-tested / hot repaired in the year	Next  Re-testing cycle	Background Colour	Background colour Shade as per IS:5	Lettering colour
2001	2006	Dove Grey	IS-694	Black
2002	2007	Black	IS-521	White
2003	2008	Yellow	IS-355	Black
2004	2009	White	IS-127	Black
2005	2010	Sea Green	IS-217	Black

(b)              The height of the lettering shall  be  of  25 mm. 

The above colour scheme shall be followed by the statutory testing plants and hot repairers. 

9.2.5          The   above  colour  coding scheme shall also  be  followed  by  the Oil          Industry in respect of cylinders in circulation due for next testing.

9.2.6          It is essential that the periodic visual inspection of marking, painting and stamping on the cylinders is undertaken at the bottling plants to ensure that these are legible at all times.

9.2.7          Since the stamping and marking are done at the time of re-testing, the next due date of   hydrostatic  test can be easily established.

9.2.8          Statutory testing plants stenciling the next date for re-testing on the vertical stays of the cylinders with proper colour coding as above and as such the next date of re-testing can  be easily found out from the  colour coding and marking.
