CEI EN 60684-3-271

This part of IEC 60684 gives the requirements for four types of
heat-shrinkable, flame retarded, fluid resistant, elastomer
sleevings, nominal shrink ratio of 2:1.

Type A: standard wall thickness for use at temperatures up to
120 °C

Type B: thin wall thickness for use at temperatures up to 120
°C

Type C: standard wall thickness for use at temperatures up to
150 °C

Type D: thin wall thickness for use at temperatures up to 150
°C

These sleevings are normally supplied with internal diameters up
to 102 mm for the standard wall thickness and up to 51 mm for the
thin wall thickness. The standard colour is black.

Sizes or colours other than those specifically listed in this
standard may be available as custom items. These items are
considered to comply with this standard if they comply with the
property requirements listed in Tables 1, 2, 3, 4, 5 and 6 except
for 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.
