Flammabiliity: Small Part Exemption (SPE)
Flammabiliity: Small Part Exemption (SPE)
(OP)
Dear all gents,
I am installing a NOT flammability-tested small part in cabin. I heard that there is an fire retardant Exemption depend on the size of part.
So what is the size limit for such Small Part Exemption (SPE)? And is there any issued paper or regulation can be of reference?
Sincerily wait for your guidance.

RE: Flammabiliity: Small Part Exemption (SPE)
There are exemptions as you suspect, but those are worked out individually with the certification authority and are therefore generally proprietary.
So why not just get samples that are specimen-sized and just test. Choosing fire retardant materials is nice but does not take the place of a test. A good predictor. The reason I don't do flammability is half the day is spent having to listen to clever new schemes of avoiding test.

But if you think you have a valid case for not doing one, it surely wouldn't hurt to present that to your certificating authorities.

Just remember what happened to Grissom, White and Chaffee due, at least in-part, to small pieces of flammable velcro all over the inside of their Apollo 1 capsule.
