Foreword
GB/T 11026 "heat-resistant electrical insulating materials" currently consists of six parts.
--- Part 1. Ageing procedures and evaluation of test results;
--- Part 2. Test selection criteria;
--- Part 3. Calculation procedure thermal characteristic parameters;
--- Part 4. Ageing ovens - Single - chamber ovens;
--- Part 5. aging oven temperature of 300 ℃ Precision oven;
--- Part 6. Ageing ovens - Multi-chamber ovens.
This section GB/T Part of 411,026.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 11026.4-1999 "determine the heat resistance of electrical insulating materials Guidelines - Part 4. Ageing ovens - Single Room
Oven ", compared with the GB/T 11026.4-1999, the main technical changes are as follows.
--- The standard name is more concise;
--- Chapter 2, "Normative references" removed "GB/T 2951.2-1997", adds "GB/T 27025-2008",
"IEC 60335";
--- Standard chapters vary, depending Appendix NA.
This section uses the translation method identical with IEC 60216-4-1.2006 "Electrical insulating materials - Thermal resistance - Part 4-1. Ageing ovens
Single-chamber ovens. "
Correspondence between the consistency of the standards of international documents and normative references of the following documents.
--- GB 4706 (all parts) Household and similar electrical appliances - Safety [IEC 60335 (all parts)].
For ease of use, and this part of IEC 60216-4-1.2006 compared to do the following editorial changes.
--- Use the decimal symbol "." Decimal symbol instead of "."
--- Increase the informative appendix NA.
This part is proposed by the China Electrical Equipment Industrial Association.
This part of the National Electrical insulation materials and insulation systems assessment Standardization Technical Committee (SAC/TC301) centralized.

This section was first released in September 1999, this is the first revision.
Heat-resistant electrical insulating materials
Part 4. Ageing ovens - Single - chamber ovens
1 Scope
GB/T 11026 provisions of this part of the evaluation of the heat as electrical insulation with ventilation, electric oven single room (with or without strong
Forced air circulation) the minimum requirements, but also provides the aging oven acceptance tests and operation control tests.
This section applies to within 20 ℃ ~ 500 ℃ higher than the ambient temperature of the whole or part of the oven temperature range within the operating range.
