Summary of IEC 62368 Product Safety Regulatory Compliance Testing

Electrical energy transfer occurs when there are two or more electrical contacts to the body. The first electrical contact is between a body part and a conductive part of the equipment. The second electrical contact is between another body part and earth, or another conductive part.

Equipment is provided safeguards to reduce the likelihood of painful effects and injury due to electric current passing through a human body. Electrical energy sources can be classified into three categories.

          ES1: ES1 is a class 1 electrical energy source with specified current or voltage levels. These levels can not exceed ES1 limits under normal operating conditions. Additionally, energy can not exceed abnormal or single fault conditions of a component not serving as a safeguard.

          ES2: ES2 is a class 2 electrical energy source. The prospective touch voltage and the touch current must exceed ES1 limits. This is true under normal, abnormal, and single fault operating conditions.

          ES3: ES3 is a class 3 electrical energy source where both prospective touch voltage and touch current exceed the limit for ES2.

The IEC 62368 standard test method requires equipment to be performed at normal operating conditions. For continuous operation, the equipment is operated until the steady-state conditions are established. For intermittent operation, the unit is operated until steady-state conditions are established, using the rated “ON” and “OFF” periods. Lastly, for short-time operating conditions, the time is specified by the manufacturer.

Scope of Electrically-Caused IEC 62368 Product Safety Testing

The temperature of the electrical insulation material can not exceed specified limits. This temperature ranges from 100 C to 225 C. The IEC 62368 standard classes are related to the temperature classes of electrical insulating materials in accordance with IEC 60085. For each material, data is taken into account for the material that determines the appropriate temperature.

Insulation consisting of insulating materials, clearances, creepage distances, and solid insulation is designated basic insulation. However, this is only for equipment that is providing a safeguard function.

The most common safeguard against an electrical energy source capable of causing injury is electrical insulation (also known as double insulation or reinforced insulation) placed between the energy source and a body part. Likewise, a reinforced safeguard may be placed between an electrical energy source capable of causing injury and a body part.

All clearances and test voltages apply to an altitude of 2000m. Clearances are dimensioned so the likelihood of a breakdown is due to:

  • Temporary overvoltages;
  • Transient voltages that may enter equipment;
  • Peak working voltages that are generated within the equipment;
  • Frequencies that are generated within the equipment are reduced.
