The 23197-1 or NEMA 23197-1 standard is essentially an international guideline for the emission rates of electrical devices and components. It exists to ensure that the levels of electric and magnetic fields released from equipment do not pose any harm to humans or other organisms.

This standard certifies the levels of emission for different types of industrial electrical components and devices, such as relays, disconnected switches, contactors, electronic controllers, inverters, electric motors, and transformer cores. The levels of radiation these devices emit must conform to the stated specifications in the standard in order to be properly certified.

The purpose of the NEMA 23197-1 standard is to ensure the safety of people while they are in the presence of electrical devices. It limits the amount of radiation released and sets a maximum exposure limit for people in the vicinity. This is done to minimize any health risks or harm caused by electromagnetic field (EMF) radiation. This standard is also used to protect other organisms from radiation levels that could be dangerous to them as well.

The NEMA 23197-1 standard is based on a combination of the American National Standards Institute (ANSI) and the International Electrotechnical Commission (IEC) emission ratings. This means that the ratings conform to both ANSI and IEC standards. It also ensures that all certified electrical devices in the United States are compliant with the standards established in Europe, Canada, and other countries.

Once an electrical device has passed the NEMA 23197-1 standard, it is then labeled with a rating label. This label shows the maximum emission limit of the device, which does not signify the power output of the device. It just shows the maximum emission limit as set by the NEMA standard.

The NEMA 23197-1 standard is used for many types of devices operating at frequencies ranging from 10 kHz to 300 GHz. It applies to AC and DC motors, pumps, alternators, generators, and other electric and electronic components. It also applies to wireless communication devices including FM, AM, radio, satellite, and television antennae.

The working principle of this standard relies on calculations and measurements of the average magnetic field released from electrical and electronic machinery and components. It can measure the frequency, magnitude, and duration of the emitted field. Furthermore, the standard can measure the electric field strength from the power lines connected to the device. Once all of this data is collected, the NEMA 23197-1 standard assigns the device or component an emission rating.

The NEMA 23197-1 standard is an important component of industrial safety. It sets a limit on the amount of EMF radiation released from electrical and electronic components. This helps minimize the risk of health hazards and potential harm to humans and other organisms.
