Foreword
GB/T 5591, Combined flexible materials for electrical insulation, is divided into the following parts.
-- Part 1. Definitions and general requirements;
-- Part 2. Methods of test;
-- Part 3. Specifications for individual materials.
This Part is Part 1 of GB/T 5591.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 5591.1-2002, Combined flexible materials for electrical insulation - Part 1. Definitions and general requirements. Compared with GB/T 5591.12002, the major technical changes are as follows.
-- the reference standards in “Normative references” are updated and nine reference documents are newly added (see Clause 2; Clause 2 of 2002 edition);
-- “normative reference” is added in Table 1 and the “specific groups” of “film” are reduced from six to three (see Table 1 of Clause 4; Table 1 of Clause 3 of 2002 edition).
This Part was redrafted by modifying and adopting IEC 60626-1.2009, Combined flexible materials for electrical insulation – Part 1. Definitions and general requirements.
The technical differences between this Part and IEC 60626-1.2009, and the reasons are as follows.
--for normative references, this Part gives some adjustments of technical differences, in order to adapt to the technical conditions in China. The adjustments are intensively reflected in “Normative references” of Clause 2. The adjustments are as follows.
 use GB/T 5591.3, which is drafted by modifying and adopting the international standard, to replace IEC 60626-3.2008;  use GB/T 13542.4-2009, which is drafted by modifying and adopting the international standard to replace IEC 60674-3-2.1992;  use GB/T 13542.6-2006, which is drafted by modifying and adopting the international standard, to replace IEC 60674-3-4/6.1993;  use JB/T 12169-2015, which is drafted by modifying and adopting the international standard, to replace IEC 60641-3-2.2007.
Combined flexible materials for electrical insulation –
Part 1. Definitions and general requirements
1 Scope
This Part of GB/T 5591 contains the definitions related to and the general requirements to be fulfilled by combined flexible materials for electrical insulation.
This Part applies to combined flexible materials for electrical insulation, but it does not apply to those which are made using mica paper as the primary component.

5 General requirements
5.1 The material may be delivered in sheets cut to fixed length or in rolls.
5.2 All materials in any one consignment shall be consistent and have properties within the limits of this Part throughout the whole sheet or throughout the whole length of each roll. The surface shall be uniform, reasonably smooth and reasonably free from defects such as bubbles, pin holes, creases and flaws.
5.3 When delivered in rolls, it shall be capable of being unrolled without damage.
5.4 The combined materials shall be free of conducting particles and other undesirable inclusions.
5.5 Materials delivered in sheets cut to fixed length shall be reasonably free from warp.
NOTE. After bonding, materials produced in roll form often assume a "roll set" which depends upon time and temperature of storage. Sheets made from such rolls may require appreciable time before warp is relieved.
6 Dimensions
Thickness and thickness tolerances are dealt with in GB/T 5591.3, Specifications for individual materials. Other dimensions and tolerances shall be agreed by t......
