Constructional details

Introduced: September 1968

Full Title

Radiation pyrometry, e.g. infrared or optical thermometry > Constructional details

CPC subdivides this area 3x more granularly than IPC with 12 additional codes.

12 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.
