What is PD IEC TR 63167- Human exposure to electric, magnetic and electromagnetic fields: contact current measurement about?
PD IEC TR 63167 is a safety standard on assessment of contact current related to human exposure to electric, magnetic and electromagnetic fields.
PD IEC TR 63167 provides general information on the assessment of contact current related to human exposure to electric, magnetic and electromagnetic fields.
The contact currents in this context occur when a human body comes into contact with a not electrified conductive object exposed to an electric and/or magnetic field at a different electric potential owing to electric and/or magnetic induction to the object. This is distinguished from the issue of electrical safety where contact with live parts of a conductive object is dealt with.
In reference to the international EMF guidelines [1]-[4] 1, the frequency range of contact current covered in PD IEC TR 63167 is direct current to 110 MHz, and only steady-state (continuous) contact currents are covered.
Note: Transient contact currents (spark discharges) may occur immediately before the contact with the object, is not covered.
Who is PD IEC TR 63167- Human exposure to electric, magnetic and electromagnetic fields: contact current measurement for?
PD IEC TR 63167 on assessment of contact current related to human exposure to electric, magnetic and electromagnetic fields is relevant to:
- Electrical engineers
- Electromagnetic engineers and designers
- Electricians
- Testing authorities
- Manufacturers of power equipment and electric appliances
Why should you use PD IEC TR 63167- Human exposure to electric, magnetic and electromagnetic fields: contact current measurement?
PD IEC TR 63167 provides guidelines for limiting human exposure to electric, magnetic and electromagnetic fields (EMF guidelines), limits for the contact current are given to avoid adverse indirect effects, i.e., electric shocks and burn hazards caused by contact with a conductive object located in an electric and/or magnetic field, when the object has an electric potential owing to electric or magnetic induction to the object. PD IEC TR 63167 gives a huge amount of knowledge, as well as many standards and regulations on the issue of electrical safety (i.e., direct contact with live part of the conductive object) to avoid severe electric
shock hazards. Therefore, PD IEC TR 63167 assists the user with the evaluation methods used in the field of electrical safety that are of useful references. This PD IEC TR 63167 summarizes general information on the assessment of contact current related to human exposure to electric, magnetic and electromagnetic fields. PD IEC TR 63167 also assists with a wireless power transfer (WPT) system, which is a system capable of transferring power between a transmitter and receiver using wireless technologies including electromagnetic induction. They are used for wirelessly charging mobile phones, tablet PCs, electric vehicles (EV), so forth. PD IEC TR 63167 provides several types of WPT, and the frequency range used is from tens of kilohertz to tens of megahertz.
Overall, PD IEC TR 63167 is useful as it helps in evaluating the contact current, in the context of human exposures to the above that are well established.
