22kN to wymóg dopuszczenia przez certyfikaty europejskie dla pętli/taśm wspinaczkowych i Dyneema 6mm je spełnia, o ile tak stoi na etykiecie. Obaw nie ma.
W ostatnim numerze BMC Summit (58) jest dobry tekst autorstwa Dana Middletona o taśmach, nylon vs dyneema, itd. Pisze on ciekawą rzecz, cytuję:
"Drop testing shows that you could break a Dyneema sling by falling directly onto it but before
you panic and bing all your slings, remember that it's better never to get into a position where
falling directly onto any sling is possible."
Ben Lyon (http://www.lyon.co.uk/) na pytanie Dyneema vs Nylon odpowiada:
"[Dyneema] it has no stretch whatsoever (so must never be used if any sort of dynamic load could be imposed, has very low melting point and is very slippy (so it can't be knotted safely and must be bought as sewn loops). Nylon slings (...) they are more forgiving of dynamic impact and you can use tape knots."
