What is BS EN 60684-3-240 to 243 – Heat-shrinkable PTFE sleeving about?
BS EN 60684-3-240 to 243 is one of the parts of the series on flexible insulating sleeving. BS EN 60684-3-240 to 243 is a European Standard that specifies individual types of sleeving.
BS EN 60684-3-100 to 105 gives the requirements for three types of heat shrinkable (low and high shrink ratio) polytetrafluorethylene (PTFE) sleeving.
These sheets of IEC 60684-3 give the requirements for heat-shrinkable (low and high shrink ratio) polytetrafluorethylene (PTFE) sleeving. It is normally available in expanded internal diameter sizes up to 12 mm in three wall thickness ranges as supplied in the low shrink ratio (sheets 240, 241 and 242) and up to 100 mm in one wall thickness range as supplied in the high shrink ratio (sheet 243). It is normally available in transparent milk white to light tan in colour and the minimum recovery temperature is 350 C.
The procedures described in IEC 60216-1 for evaluation of thermal endurance are not readily applicable to PTFE: however, experience of product performance indicates that this sleeving may be suitable for inclusion in systems for operation at temperatures up to 250 C.
Sizes other than those specifically listed in this standard may be available as custom items. The items shall be considered to comply with this standard if they comply with the property requirements listed in tables 3 and 4.
