Metallographic standards (with 10 to 11,600 ppM H/sub 2/) for estimating hydrogen content of LWBR Zircaloy-4 tubing were prepared by corrosion of Zircaloy-4 tubing specimens in LiOH solutions at 600/sup 0/F and 680/sup 0/F. Microstructures and measured hydrogen contents of several standards agreed well with microstructures and measured hydrogen of an irradiated corroded Zircaloy-4 tubing specimen and an unirradiated hydrided Zircaloy-4 sheet specimen. Vickers hardness data and corrosion weight gain data also are presented. 34 figures, 5 tables.
