EVS-EN IEC 60684-3-216:2019

This sheet of IEC 60684-3 gives the requirements for four types of heat-shrinkable, flame-retarded, limited-fire-hazard sleeving with a thermal endurance rating of 105 °C as shown below:
Class A: thin wall shrink ratio 2:1 internal diameter up to 102,0 mm
Class B: medium wall shrink ratio 2:1 internal diameter up to 60,0 mm
Class C: thick wall shrink ratio 2:1 internal diameter up to 51,0 mm
Class D: medium wall shrink ratio 3:1 internal diameter up to 40,0 mm
These sleevings are normally supplied in the following colours: black, red, green, blue, white, yellow and green/yellow.
Sizes or colours other than those 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 5, 6, 7 and 8, excluding dimensions and mass.
Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
