ASME B&PVC Section VIII Div 1 question regarding "Seal"

Banging my head over this one...

UG-136(a)(7) states that pressure relief device design must have means for "sealing all initial adjustments which can be made without disassembly of the valve" and "Seals shall be installed in a manner to prevent changing the adjustment without breaking the seal"

Now - apparently most valves under this division have a wire seal. But ours is too small for that. It's only about 1" long.

What I'm banging my head against is what exactly is a "seal".
Are they looking for tamper evident or tamper "proof".
Would a dot of epoxy on an adjusting nut be enough? That way if it's tampered with it's known.
