This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
drafting:
This document is modified to adopt IEC 60684-3-281:2010 "Insulated hoses Part 3: Specifications for various types of hoses Part 281: Half
Conductive Polyolefin Heat Shrink Tubing":
Compared with IEC 60684-3-281:2010, this document has made the following structural adjustments:
--- Added Chapter 3 "Terms and Definitions";
---Chapter 5 corresponds to Chapter 1, Chapter 5 and Table 1 and Table 2 of IEC 60684-3-281:2010, of which 5:1 corresponds to IEC 60684-3-
281:2010, the third paragraph to the sixth paragraph of Chapter 1, 5:2 corresponds to Chapter 5 of IEC 60684-3-281:2010;
---Chapter 6 corresponds to the test method in column 2 and the remarks in column 6 in Table 1 of IEC 60684-3-281:2010;
---7:4 The third paragraph corresponds to Chapter 6 of IEC 60684-3-283:2010;
--- Deleted Chapter 3 of IEC 60684-3-283:2010;
--- Added Chapter 7 "Inspection Rules" and Chapter 8 "Marking, Packaging, Transportation and Storage":
The technical differences between this document and IEC 60684-3-281:2010 and their reasons are as follows:
--- Deleted the seventh paragraph of Chapter 1 "For medium-voltage cable accessories, it must be verified in accordance with HD629 and IEC 60502 series standards
"Electrical performance after assembly" to meet my country's national conditions and facilitate application;
--- IEC 60502 (all parts), IEC 60757:1983 and HD629 referenced normatively have been deleted in order to conform to my country's national conditions and facilitate
for application;
---Deleted "name", "description, IEC standard number, type, size, color" and "storage dimensional stability" related content, in order to comply with
my country's national conditions, easy to apply;
--- The normative reference document GB/T 2828:1-2012 (see 7:3) has been added to meet the technical conditions of our country and facilitate application;
---Replace IEC 60684-2:1997 Amd1:2003 Amd2:2005 with the normative reference GB/T 7113:2-2014
(see Chapter 6), the degree of consistency between the two documents is modified to meet the technical conditions of our country and facilitate application;
--- Changed the "length change", changed "-10" to the minimum value; changed the "volume resistivity", changed the "minimum value" to "maximum
Value" (see Table 1), in order to meet the technical conditions of our country and facilitate application;
--- Increase the test temperature tolerance of "low temperature bendability" and the completion test time of "fluid resistance" (see 6:4 and 6:7) to meet I
national conditions, easy to apply;
--- Added "inspection rules" and "marking, packaging, transportation and storage" related content (see Chapter 7 and Chapter 8) to comply with my country's technical regulations
pieces for easy application:
The following editorial changes have been made to this document:
--- In order to coordinate with existing standards, change the name of the standard to "Semiconductive Polyolefin Heat Shrinkable Tube";
--- The unit "K" is replaced by the unit "℃";
--- Changed the "wall thickness" in Appendix A to "minimum value after shrinkage":

3 Terms and Definitions
This document does not have terms and definitions that need to be defined:
4 Test conditions
In the absence of regulations, semi-conductive polyolefin heat-shrinkable tubes should be shrunk at:200°C ± 3°C in an oven with forced air circulation
Test after 10min±1min:
5 Technical Requirements
5:1 General requirements
Semiconductive polyolefin heat shrink tubing is divided into two types: Type A (thin wall) and Type B (medium wall), and the inner diameter of Type A (thin wall) usually does not exceed
195:0mm, the inner diameter of type B (middle wall) usually does not exceed 120:0mm: The color is generally black, see Appendix A for inner diameter and wall thickness, and can also be determined by
The supply and demand sides negotiate to determine: In special application cases, the selection of materials should fully meet the performance requirements in the application, rather than just based on this
document:
5:2 General and performance requirements
In addition to the general requirements specified in GB/T 7113:1-2014, the semi-conductive polyolefin heat shrinkable tube should also meet the requirements of Table 1 and Table 2:
