[HomeBrew] Is all "plastic" pipe the same?

[Doug Laidlaw]

It has been suggested here in Oz, that you can test the RF capabilities of 
plastic pipe by putting a sample in a microwave oven.  If it doesn't melt, it 
is O.K.  Of course, put it on a paper plate, and put in a cup of water to 
load the oven.  I haven't actually tried it, and it probably says nothing 
about the UV resistance.
