Brandon,

The latest version is 1993 (D256-93a), approved 15/10/93 and printed
12/93.

I do not know of any RP specific standards. Perhaps the resin
representatives on the list (Ciba: Bob Kruger -- bob.kruger@cibasc.com;
Dupont: Michelle Wyatt -- michelle.p.wyatt@usa.dupont.com) can be of
assistance.

Cheers.
