comment How to disentangle effects of components in system?
Thanks g g , I'm afraid that I can't just disregard the effect of the valve and I need more measurements to assess the effect of the valves as well ...

Thanks Gillaume, I'm afraid that you're right and I need more measurements to assess the effect of the valves as well ...

comment How to disentangle effects of components in system?
Thanks Guillaume for the answer. Simply using a t-Test sound for me like disregarding the influence of the valve, which I'm afraid I can't do

comment What is the maximum load for lateral loading of a screw?
Well the drawing is not to scale, so the space between the nut and the wooden parts wouldn't be so big as to fit a finger inside. The nut is just a spacer between the two wooden parts, so at most a fraction of a mm should be between nut and wooden part

"designed to remove fingers"? What part doesn't seems safe?

comment What is electric flux density?
The OP is not using "non-standard terminology". In electrical engineering text (for instance "Introduction to Electromagnetic Fields" from Paul and Nasar, page 91 and "Engineering Electromanetics" from Hayt, 9th edition, page 48) the field D is called electric flux density. Furthermore, in German the corresponding name elektrische Flussdichte is widespread

comment High-voltage PCB design and IPC 2221
Thanks for your comments, but I'm not looking into advice for designing this PCB, I am interested in knowing why does the IPC 2221 standard requires much bigger spacing than the one required by dielectric strength consideration

@vir Safety factor of 2 sounds reasonable, but IPC 2221 requires waaay more.

@winny Voltage will be continuously applied. Solder mask should provide protection against pollution
