Standard Specifiying Use of Nylon Cable Tie for Cable Gressing on Cable Tray

Something about induced currents in small conductors wrapped around larger ones?

Standards with ties addressed here, but I didn't see a material mentioned.

NEC 830.24, 334.30, 332.30, 330.30, 320.30: ...cables shall be secured by hardware including straps, staples, cable ties, hangers, or similar fittings designed and installed so as not to damage the cable. Over and over again in regard to the material type and method of entry/routing with nothing specific to material type. Damage to the cable is what is most important there (NEC).

Marine standards disallow the use of plastic ties due to fumes released during fire in closed spaces, and also plastic strapping melting and dropping cable bundles, effectively blocking a passageway. Many vessels do not use trays and use the strength of the bundle to carry the load. I do not have those standards handy.

Don't install nylon anywhere there is a risk of hydrogen chloride vapours being present, such as near HCl tanks and in ion exchange water treatment plant. Irrespective of any standard, they won't last overnight.

Use PVC ones instead.

PVC, nylon, ABS.....plastics

I've experienced the use of the word "nylon" to "specify" cable ties. One has to decide what's best in the environment of deployment. (It is a bit like saying "hoover" for vacuum cleaner)

I've just finished one factory fit out where any sort of plastic cable tie was prohibitted (except inside electrical enclosures, thank ferk). On this project all the cabling (some 10km) had to be secured to the cable management systems with steel wire. This directive was to eliminate any possibility of contamination of the product being processed. (steel can be magnetically removed and isn't toxic)
