50%: the first time that 50% or more of bits are reported erased


120%: when all of the bits have been erased consistently for 20% of the runtime (actually 20% / 80% => 25% more than erased)

For eetime results see EPROM Sensitivity

Xenon erasure

These emit very high peak intensity and seem to erase EPROMs faster

"It seems (because I got it by net auction and don't know exact company of this product), Xenon flasher for UV-rom erasing..."

"5 seconds possible"

Dataman Strobe Erase

10-30 seconds typical
