Introduced: January 2015

Title

Titles differ between systems:

IPC: Cooling arrangements

CPC: Cooling arrangements (air-treatment systems dissipating or using the heat of lighting fixtures F24F3/056)

Full Title

Full titles differ between systems:

IPC:

Protecting lighting devices from thermal damage; Cooling or heating arrangements specially adapted for lighting devices or systems > Cooling arrangements

CPC:

Protecting lighting devices from thermal damage; Cooling or heating arrangements specially adapted for lighting devices or systems (lighting fixtures combined with outlets for air-treatment systems F24F13/078) > Cooling arrangements (air-treatment systems dissipating or using the heat of lighting fixtures F24F3/056)

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2015.
