Testing D-76.

Forget when I mixed up a liter of this but I'd like to know if it's still usable.Can I use a clip test like the one for my fix?

Thanks

See if you get a maximum black at your normal Dev time. Or better still stick a 35mm film in a camera shoot a few frames, open the camera in the darkroom and cut the film, just process those few frames.

If it is dark brown, or smells strongly there is little need to test - it is oxidized too much to be useful.
