understandind zs correction factors?

[darren111]

Hi all, could someone explain how to use the correction values from the OSG. Are these values the max zs that can be for used for the devices to work.

Does the bs7671/2008 give mathematical values and then osg gives 80% of those and if the ambient temp of the room is higher we have to use the correction values? sorry if this makes no senseheadbang

Max Zs values in 7671 are for fault condition temp.

adjusted values of 80% are for TEST condition temp.

So when testing, Zs must meet 80% values to ensure protection
