GB/T 18800-2017Household microwave oven -- Methods for measuring performance (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 18800-2008 "household microwave oven performance test methods", and GB/T 18800-2008 the main technology the changes are as follows.

--- Added microwave function, combined microwave function, set to shutdown mode, set to standby mode, cooling and food stand Definition (see Chapter 3);

--- Increase equipment and measurement requirements (see 6.7);

--- Removed paste performance test (2008 edition of Chapter 5);

--- The original "7.2 effective cavity size" and the original "7.3 effective volume" into "7.2 effective cavity size and calculated volume", and Modify the relevant content (see 7.2, 7.2 and 7.3 of the 2008 edition);

--- Added "7.3 total internal dimensions and total volume" clause content (see 7.3);

--- Removed the original Appendix A "paste selection heating test" (2008 edition of Appendix A);

--- Original Appendix B "Regional Thaw Test" was changed to Appendix A "Regional Thaw Test" (see Appendix A, 2008 edition of the appendix B);

--- Added Chapter 14, Chapter 15, Appendix B ~ Appendix F (see Chapter 14, Chapter 15, Appendix B ~ Appendix F).

This standard uses the translation method identical with IEC 60705:2014 (Ed4.1) "household microwave oven performance test methods." the documents of our country that are consistent with the corresponding international documents that are normative references in this standard are as follows.

1 Scope

This standard specifies the main performance characteristics of household microwave oven users interested in, and specifies the test methods for these characteristics.

This standard applies to domestic microwave ovens and combined microwave ovens.

Note 1. This standard does not apply to.

--- Can not place a diameter >=.200mm or height >= 120mm load microwave oven;

--- Safety requirements (see GB 4706.21 and GB 4706.90).

Note 2. This standard does not apply to stoves that have only conventional heating methods (see IEC 60350).
