IEC 60684-3-247 REDLINE
Flexible insulating sleeving – Part 3: Specifications for individual types of sleeving – Sheet 247: Heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded, thick and medium wall
|Publication Date:||1 August 2019|
|ICS Code (Plastics and rubber insulating materials):||29.035.20|
This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded with a nominal shrink ratio of 3:1.
This sleeving has been found suitable for use at temperatures of up to 100 °C.
• Type A: Medium wall, internal diameter up to 200,0 mm typically.
• Type B: Thick wall, internal diameter up to 200,0 mm typically.
These sleevings are normally supplied in colour black.
Since these types of sleving cover a significantly large range of sizes and wall thicknesses, Annex A (Tables A.1 and A.2) provides a guide to the range of sizes available. The actual size will be agreed between the user and supplier.
Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
