mesh fabric meeting 25.855 burn

mesh fabric meeting 25.855 burn

(OP)
Hi guys.  Anybody know of a 9X9 mesh fabric that will pass burn tests per 25.855?  This is a 9G separator net for a bulk loaded airplane.  The mesh is used to keep smaller stuff in place.  I'd  use herculite, but can't because the customer doesn't want to re-do the smoke detection test.

Not sure what was used originally.  The customer and their original supplier are not on speaking terms.

RE: mesh fabric meeting 25.855 burn

You might be confused, 25.855 is for the liner (walls, ceiling, floor) and not separator nets.  Liners have to meet burn-through per Appendix F25.3.  Tiedown equipment would only have to meet Appendix F25.1, 4.0 ipm horizontal test, most every nylon and polyester would easily meet.  Wise to use identical size/pitch/open space mesh to remain similar to existing smoke detection test results.

der8110,

Thanks for the reply.  Non-liner materials are covered in 25.855(d).

My concern is that the mesh is vinyl coated, like that used on dump truck covers.  I'm looking at Bo-Tex 1300.  They say that it meets some sort of horizontal burn test.  I'm going to call them today to get clarification.
