When dry pressure testing a gas pipe before the meter is connected. Do you tend to just go to 1.5 times working pressure. Meaning a pressure of 0.2 x 1.5. So 0.3mb. Or is it advisable to go higher than this if pipes are getting encased etc.

OK, where do you derive 0.3mb from?
I assume (dangerous I know....) that you meant 20mb, * 1.5 = 30mb. But, as standing pressure is meant to be circa 27mb (but, often goes to 30+mb before regulator takes it back down to nominal 27mb), a test of 27mb*1.5 would be closer to 41mb....
What do your books say?, what do the people you are training with (to get the portfolio together) say?, what does the course trainer say?

The online copy of the viper book I have doesn't mention dry testing the pipe before covering well it does but doesn't mention the pressure to do it at. The gas person I have worked with before sadly doesn't bother testing it before taping and covering.
