[Test-Equipment] How to get a capacitor standard calibrated/validated/verified?

[Pete Lancashire]

I was lucky when I ended up with a box or 1409's. A small met lab near
me let me use their traceable GR 1620A in trace for two spare 'scope
probes that sell on each for around $30-50 each. No stickers tho'

I would ask around, many met labs are hungry
