The main change with regard to EN 60684-3-233:1998 concerns the replacement of the thermal endurance test, according to EN 60216, by a long-term ageing test, i.e. 3 000 h, at the maximum recommended temperature for such use, in order to furnish thermal test data within a work
18、able time frame. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2008

The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1) Part 2: Methods of test (IEC 60
23、684-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard gives one of the sheets comprising part 3 as follows: Sheet 233: Heat-shrinkable fluoroelastomer sleeving, flame retarded, fluid resistant, shrink ratio 2:1.

24、Part 3: Specifications for individual types of sleeving Sheet 233: Heat-shrinkable fluoroelastomer sleeving, flame retarded, fluid resistant, shrink ratio 2:1 1 Scope This standard gives the requirements for two types of heat-shrinkable, flame retarded, fluid resistant1), nominal shrink ratio 2:1, f
25、luoroelastomer sleeving for use at temperatures up to 200 C: Type A: thick wall; Type B: thin wall. These sleevings are normally supplied with internal diameters up to 51 mm, and the standard colour is black. Sizes or colours other than those specifically listed in this standard may be available as
26、custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in Tables 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 m
27、aterial 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 2 Normative references The following referenced documents are indispensable for the application of this document.
