The IEC developed a standard to rate DMMs based on the maximum voltage spike the meter can withstand without causing an arc. True or False?

The statement regarding the IEC (International Electrotechnical Commission) developing a standard to rate Digital Multimeters (DMMs) based on their ability to withstand maximum voltage spikes without arcing is indeed true. The IEC established standards, specifically IEC 61010, which outlines safety requirements for electrical measuring instruments, including DMMs.

This standard includes classifications that help determine the maximum transient overvoltage that a DMM can handle safely. Such ratings are crucial for ensuring the reliability and safety of electrical measurements, especially in environments where voltage spikes may occur. By adhering to these standards, manufacturers can provide users with important information about the operational limits of their devices under electrical stress conditions.

The other options, such as the idea that the standard applies only to certain models or is not applicable in the U.S., do not accurately reflect the comprehensive nature of the IEC standards nor their international relevance in ensuring safety in electrical measurements across all applicable devices.
