Full Title

Full titles differ between systems:

IPC:

Ohmic-resistance heating > Heating elements having the shape of rods or tubes > non-flexible > heating conductor embedded in insulating material

CPC:

Ohmic-resistance heating > Heating elements having the shape of rods or tubes (H05B3/62, H05B3/68, H05B3/78 take precedence) > non-flexible > heating conductor embedded in insulating material

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
