Detection or location of defective computer hardware by testing during standby operation or during idle time, e.g. start-up testing

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Error detection; Error correction; Monitoring > Detection or location of defective computer hardware by testing during standby operation or during idle time, e.g. start-up testing

CPC:

Error detection; Error correction; Monitoring (error detection, correction or monitoring in information storage based on relative movement between record carrier and transducer G11B20/18; monitoring, i.e. supervising the progress of recording or reproducing G11B27/36; in static stores G11C29/00) > Detection or location of defective computer hardware by testing during standby operation or during idle time, e.g. start-up testing

CPC subdivides this area 4x more granularly than IPC with 10 additional codes.

10 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
