with conversion into electric or magnetic values

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Measuring acceleration; Measuring deceleration; Measuring shock, i.e. sudden change of acceleration > by making use of inertia forces > with conversion into electric or magnetic values

CPC:

Measuring acceleration; Measuring deceleration; Measuring shock, i.e. sudden change of acceleration > by making use of inertia forces (G01P15/14 takes precedence) > with conversion into electric or magnetic values

Of 17 combined children, 9 exist in both systems.

8 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.
