GB/T 20629.2-2013on-cellulosic paper for electrical purposes -- Part 2: Methods of test (English PDF)

Foreword

GB/T 20629 "electrically non-cellulose paper" contains the following sections.

--- Part 1. Definitions, designations and general requirements;

--- Part 2. Test methods;

--- Part 3. Specifications for individual materials.

This is Part 2 GB/T 60629 of.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses redrafted law revision using IEC 60819-2:2001 "Non-cellulosic papers for electrical purposes - Part 2. Test methods." Technical differences exist compared to 2001 are as follows. IEC 60819-2 and this part.

--- Remove the IEC 60819-2:2001 Foreword;

--- Remove the IEC 60819-2:2001 Chapter 3, the definition of the sample and the sample;

--- Press mechanical properties, electrical properties, physical and chemical properties on the order of the chapters have been adjusted and editorial changes;

--- Increased test methods "volume resistivity" "surface resistivity" "Temperature Index", "thermal conductivity" and "oxygen index" five properties, According to this and the corresponding increase in the normative references. At the same time easy to write, an increase of GB/T 5591.2-2002 "electricity Gas flexible composite material - Part 2. Test methods "and GB/T 20628.2-2006" electric with Part 2 of cellulose paper Min. Test methods "Two normative references.

--- Increase the informative Appendix A.

This part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.
