Which grade of PVC piping do I need in order to sustain a 1,000Pa vacuum?

I’m rigging a proof of concept DIY machine, in which the internal pressure will need to be at most 1/50th of atmospheric pressure. For a safety margin, I want the machine to withstand 1/100th atmospheric pressure (or about 1,000 pascals). What grade of PVC piping do I need in order to prevent implosion? Or, is PVC piping, not the best suited for the job? I don’t have access to a laboratory, so things I can pick up at a store would be ideal. Many thanks.
