Leak Testing of CO2 Cylinders Testing Method ::: 
	 
	Required Materials :::
	1) Transparent Polythene bags of a suitable size to fit over the head of the cylinder. For eg. for 5.5" diameter cylinder the bag size is approximately:- 9" open width x 12" length. And For a 4" diameter cylinder, bag size is approximately 6.5" open width x 12" length. And For a 3.5" diameter cylinder, bag size is approximately 5.75" open width x 12" length.
	 
	2) Elastic bands of a suitable size to tighten Polythene Bag on Cylinder Head to Make sure there are no air gaps in the seal.
	 
	3) A measuring cylinder, 25 ml capacity.
	
	4) Test Solution -  RXSOL-66-6201-500, The solution shall be stored in a cool place in dark coloured glass bottles with a tight fitting screw cap. If so stored the shelf life is approximately 12 MONTHS.
