IEC 60994:1991/COR1:1997

IEC 60994:1991/COR1:1997 is a corrigendum to the guide for field measurement of vibrations and pulsations in hydraulic machines, helping users apply the parent document with corrected technical guidance. For engineers, test specialists, and compliance teams, it supports more reliable documented evaluation of vibration and pulsation measurements on turbines, storage pumps, and pump-turbines. IEC 60994:1991/COR1:1997 is most relevant where technical validation, measurement consistency, and quality workflows depend on accurate reference material.

IEC 60994:1991/COR1:1997 standard overview

This corrigendum is a supporting document linked to IEC 60994:1991, not a standalone technical specification. It addresses the field measurement guidance used for hydraulic machines where vibration and pulsation behavior must be assessed under operating conditions. In practice, the document is useful when teams need to confirm that their technical review, test planning, or conformity assessment references the corrected wording from the parent guide. It is especially relevant for controlled engineering documentation and compliance preparation.

Applications of IEC 60994:1991/COR1:1997

IEC 60994:1991/COR1:1997 may be used in testing workflows for hydroelectric and pumped-storage equipment, particularly during site measurements on turbines, storage pumps, and pump-turbines. It can support laboratory evaluation planning, field verification activities, and procurement reviews where measurement methods need to be aligned with the parent guide. Organizations involved in operational consistency checks, maintenance studies, or technical assessment of hydraulic machinery may use the corrigendum to keep project documentation accurate.

Why IEC 60994:1991/COR1:1997 matters

Accurate corrigenda are important in engineering documentation because even small corrections can affect how vibration and pulsation data are interpreted. IEC 60994:1991/COR1:1997 helps reduce risk in compliance workflows by supporting consistent use of the corrected reference text during testing and reporting. For teams managing safety, quality assurance, or conformity assessment preparation, it can improve confidence that measurement practices are based on the right technical source and that procurement or validation decisions are supported by reliable documentation.
