ANSI/CAN/UL 9540:2020 EMC测试测试结果要求：

• 32.1.2 Each test shall begin with an operational DUT. 每个测试都应从操作并能正常运行DUT开始。
• 32.1.3 During the tests in this section, the DUT shall be operated in mode (s) that include the safety. DUT应在包括安全模块及功能在内的模式下运行。
• function(s) being evaluated. If multiple modes are to be considered (example: equipment controlling the charging and discharging of the energy storage device), the DUT shall either be cycled through those modes during the tests, or the tests repeated in each mode. While cycling through modes, the DUT shall not exhibit any signs of loss of safety functions or risk of fire, electric shock, or personal injury. 要考虑多种模式（例如：控制储能设备充电和放电的设备），则DUT应在测试期间循环通过这些模式，或者在每种模式下重复测试。在循环模式时，DUT 不得出现任何安全功能丧失或火灾、触电或人身伤害危险的迹象。
• 32.1.4 After each test in this section, the DUT shall be inspected to verify that it is still operational. This may require Operational Verification (32.8) of the DUT if it is not possible to determine that it is fully operational by inspection. If the DUT is no longer operational, a failure analysis shall be conducted to determine the reason for the failure and to verify that the DUT has failed safely. A DUT that is no longer operational shall not be used on any remaining test. 每次测试之后，应检查 DUT 以验证其是否仍在运行。如果无法通过检查确定 DUT 是否完全运行，则可能需要对 DUT 进行操作验证 （32.8）。如果 DUT 不再运行，应进行故障分析以确定故障原因并验证 DUT 是否安全失效。不再运行的 DUT 不得用于任何剩余的测试。
• 32.1.5 In addition, after all tests in this section have been completed, all samples used during the tests specified in Section 32 shall comply with the Operational Verification in Section 32.8. 在完成本节中的所有测试后，在第 32 节中规定的测试期间使用的所有样品应符合第 32.8 节中的操作验证。
