Summary This standard specifies: right in preparing polymer matrix composites under normal and abnormal conditions when the maximum permissible temperature of the list to provide guidance. This standard was discussed on the following contents and make recommendations on: a) In selecting the appropriate method for polymer-based composites will be described, we should take into account the many complex formulations are complex and thus obtained is also a wide range of performance these factors (see 5. 1), b) affect those contained in the polymer compound in the normal operating conditions of the maximum permissible temperature of the list data selection factor (see 5. 2 and 5. 3), c) a polymer matrix composite in an irregular operating conditions, the maximum allowable temperature of the list (see Chapter 6). While recognizing customary for practical reasons the use of " temperature " of the word, but still use the standard term " temperature. " If you specify a suitable reference points, such as 25��C, it can be converted into a another.

Foreword

This standard is identical with IEC 61624.1997 "Electrical equipment used in the preparation of polymer-based composites list of the maximum allowable temperature Guidelines". This standard is equivalent to using IEC 61624.1997, the editorial changes made the following. --- This standard removed from the standard introduction of IEC 61624. --- The standard reference documents, has been converted to our standard international standards, lists of standards with international standards and turn Degree. The Standard Appendix A, Appendix B is an informative annex. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Electrical insulation materials and insulation systems assessment Standardization Technical Committee (SAC/TC301) centralized. This standard was drafted. Guilin Electric Institute of Science, Technology Electrical Machinery Industry Beijing Institute of Economic Research. The main drafters of this standard. Luozhuan Yong, Xu Yuanfeng. This standard was first formulated. GB/T 22579-2008/IEC 61624.1997 Electrical equipment for preparation of polymeric composite largest Allowable temperature Listing Guidelines

1 Scope

This standard formulation in polymer matrix composites provide guidance under normal and abnormal conditions the maximum allowable temperature of the list. The standard on the following contents were discussed and made recommendations. a) In choosing the appropriate method for polymer matrix composites will be described, taking into account the many complex formula is complex and thus These factors affect the performance of a wide range is obtained (see 5.1); b) factors that affect the data contained in the list of allowed maximum temperature polymer composites under normal operating conditions selected (see 5.2 and 5.3); c) a list of the largest polymer matrix composites under abnormal operating conditions allowable temperature (see Chapter 6). Although aware of the practical reasons customary use of "temperature" is the word, but the present standard still uses the term "temperature." If the provisions of a Suitable reference points, such as 25 ℃, it can be converted into a another.
