That's the thingy...

Grade 4 is high security, typically used in defence sector. SSG manufacture a Grade 4 compliant panel, but you will need appropriate security clearance to obtain any technical information on this equipment.

I used to get security clearance and all that malarky there is such thing they use all the panels that are available on the market 

Dsc used to make one but anything that claims grade 4 is different to anything that is 3rd party certificated. Without it I could claim a logic 4 was grade 4 and self certify it was. Utterly meaningless
