When must electrical safety tests be performed on battery-powered equipment?

Battery-powered equipment should undergo electrical safety tests when it is capable of operating while connected to the charger. This is crucial because, in this state, the device can pose additional risks due to the combination of battery and mains power. The interaction between the two can potentially lead to hazardous situations if the device is not properly evaluated for safety. It is essential to ensure that all electrical safety standards are met to protect users from electrical shock or equipment malfunction.

Performing safety tests in these circumstances ensures that the equipment operates safely, particularly since the equipment might inadvertently expose users to electrical hazards if there are faults in the charging circuitry or if there's an electric shock risk while it is in use. Therefore, regular testing is an integral part of ensuring ongoing safety and compliance with regulatory standards in biomedical equipment management.
