I really believe that everyone should look in the NFPA standards and codes
to see the definition of approved. The definition is not that it is listed
or not listed or tested by anyone. The definition states "Acceptable to
the authority having jurisdiction". The AHJ can approve something that is
not listed or tested by anyone or he could demand that it meet certain
criteria or performance. On the other hand, the AHJ may base his approval
on listings and labeling practices. Bottom line is that it is solely up to
the AHJ.

There is some info in NFPA 15 concerning sizes of pipe used for stands and
height limitations.
NFPA 15-2007, 6.3.2.2.1.
Anvil has some pipe stanchions and saddles. There are probably others as
well. Or make your own.
I doubt you're going to find one that's actually "listed".

Subject: pipe stands
NFPA 13 (2007) section 9.2.6.2 says that if pipe stands are used, they must
be approved.
1. Are there any approved pipe stands?
2. Outside of the general comment on support of pipe, is there anything
specific on pipe stands in 2002? I couldn't find anything.
3. When calculating the weight of water-filled pipe for a riser manifold,
am I correct in assuming that the equipment and the vertical piping would
need to be considered? Has anyone actually done this?
