The series consists of three parts: Part 1: Definitions and general requirements (IEC 60
18、684-1) Part 2: Methods of test (IEC 60684-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard comprises one of the sheets of Part 3 as follows: Sheet 211: Heat-shrinkable sleeving, semi-rigid polyolefin, shrink ratio 2:1 EN 60684-3-211:2007 4 FLEXIBLE INSULATING SL
19、EEVING Part 3: Specifications for individual types of sleeving Sheet 211: Heat-shrinkable sleeving, semi-rigid polyolefin, shrink ratio 2:1 1 Scope This part of IEC 60684 gives the requirements for four types of semi-rigid, heat-shrinkable polyolefin sleeving with a nominal shrink ratio of 2:1 that
20、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 flame-retarded, translucent. The sleeving is
21、normally available in internal diameter sizes up to 12,7 mm as supplied, in the following colours: black, white, red, yellow, blue and translucent. Sizes or colours other than those specifically listed in this standard may be available as custom items. The items are considered to comply with this st
22、andard if they comply with the property requirements listed in tables 2, 3 and also with the property requirements of Table 4 for types C and D, excluding dimensions. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user
23、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.

Where no abbreviation is given, the colour shall be written in full. 4 Conditions of test Unless otherwise specified, the sleeving shall be shrunk in a forced air circulation oven for (5 1) min at 200 C 3 K before being tested. 5 Requirements In addition to the general requirements giv
28、en in IEC 60684-1, the sleeving shall comply with the requirements of Tables 1, 2, 3 and 4, where applicable. 6 Sleeving conformance Conformance with the requirements of this specification shall normally be based on the results from size 12,7 mm/6,4 mm black sleeving. The colour fastness to light sh
