Disclaimer
Coats Helios sewing threads are suitable for use in heat and fire fighters’ protective clothing according to EN ISO 11612, EN ISO 14116 and EN 469. They are not suitable for use in protective clothing for electricians and welders as the relatively low vertical resistance (< 105 _) material cannot guarantee protection from the possibility of electrical shock by contact with live electric conductors.
