Resumen:
IEC 60684-3-211:2007 gives the requirements for four types of semi-rigid, heat-shrinkable polyolefin sleeving with a nominal shrink ratio of 2:1 that has been found suitable for temperatures up to 135 °C.
Type A: general purpose, flame-retarded, opaque colours;
Type B: general purpose, non flame-retarded, translucent;
Type C: fluid resistant, flame-retarded, opaque colours;
Type D: fluid resistant, non flam-retarded, translucent. The major technical changes with regard to the second edition concern a better alignment with existing national specifications.
