Grounding Measurement Report: Validity Period and Contents
Short answer: A grounding measurement report is an official record documenting that a measurement has been taken and that the installation is suitable. Its validity period extends until the next periodic inspection (usually one year in workplaces). The report must include the measurement values, the method used, and information about the authorized person/accredited organization.
The report, which is the output of the grounding measurement, is one of the most important documents in the employer's possession during occupational safety and health (OSH) audits and in the event of a possible accident. However, the value of the report depends on its content and who prepared it.
What should a valid grounding report include?
- Installation and grounding system information
- The measurement method applied and the calibrated device used.
- Measured resistance and continuity values
- Comparison with regulatory/standard limit values.

Validity Period
The grounding measurement report is valid until the next periodic inspection date of the equipment; in workplaces, this is usually one year. An expired report is considered invalid during the inspection, so it must be renewed at the time of the inspection. A report issued by an accredited organization has much stronger legal and international validity.
