--- Part 4. polyester-imide varnish;
--- Part 5. Fast energy-curable melamine alkyd varnish;
This section GB/T 1981 Part 2.
The partial modification using IEC 60464-2.2001 "Electrical insulating paint PART 2. Test methods" and the first Amendment (2006)
(In English).
This section according to IEC 60464-2.2001 and 2006 to redraft the 1st amendment. This section lists the reg number in Appendix A
And IEC 60462-2.2001 and 2006 Control List 1st amendment clauses numbered.
Taking into account China's national conditions, in using IEC 60464-2.2001 and 2006 when the 1st amendment, made some changes in this section. About technology
Differences in terms of their operation pages involved are identified by the margin of a single vertical line. These technical differences are given in Appendix B and their causes
The list for reference.
For ease of use, and this part of IEC 60464-2.2001 and 2006 compared to the 1st amendment made following editorial changes.
a) Remove the IEC 60464-2.2001 Foreword and Introduction;
b) Remove the Chapter 5, Chapter 6 of the suspension segment, namely the former before drying and/or curing and drying and/or post-curable material status
Text description.
This Part replaces GB/T 1981.2-2003 ". Test methods for paints - Part 2 electrical insulation."
This portion of the GB/T 1981.2-2003 phase compare the main differences are as follows.
a) increased by 5.1 "look and feel", 5.5 "acid value", 5.12 "paint and copper reaction" reg;
b) The 6.1 "species by the substrate specific test methods and specifications for individual materials regulations, or agreement by both parties.
"To" kind of a substrate by a specific test methods and specifications for individual materials regulations, if the specific test method
And individual materials to the substrate species do not predetermined, the choice of thickness (0.10 ± 0.01) mm of thin copper. ";
"Sticky painted steel, reporting every block," c) to modify 6.4.3.5 as "coating thickness shall report each board
degree,";
d) in the 6.5.2.3 "test shall be (23 ± 2) ℃ carried out using a sinusoidal test voltage frequency of 1kHz." Modify
For the next sinusoidal test voltage frequency of the other ", the test shall be (23 ± 2) ℃, 1kHz or 50Hz or supply and demand sides agreed
get on. ";
e) increase the informative Appendix A and Appendix B.
