1 Scope
This sheet of IEC 60684-3 gives the requirements for one type of heat-shrinkable polyolefin sleeving with a temperature index of 1 35 and a nominal shrink ratio of 3:1 . The sleeving is not flame retarded. This sleeving is normally supplied with internal diameter up to 39 mm and is transparent. Sizes other than those specifically listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in tables 1 , 2, 3, 4 and 5.
