Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Ohmic-resistance heating > Heating elements having extended surface area substantially in a two-dimensional [2D] plane, e.g. plate-heater > flexible, e.g. heating nets or webs > heating conductor embedded in insulating material
CPC:
Ohmic-resistance heating > Heating elements having extended surface area substantially in a two-dimensional [2D] plane, e.g. plate-heater (H05B3/62, H05B3/68, H05B3/78, H05B3/84 take precedence) > flexible, e.g. heating nets or webs > heating conductor embedded in insulating material
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
