Earth continuity and bonding test
Earth continuity is a number and it drifts slowly. On ordinary circuits the periodic inspection covers it; on hazardous-area equipment a permanent monitor should.
What does an earth continuity and bonding test involve?
Earth continuity and bonding test checks: earth fault loop impedance (ohms), continuity resistance. Observed by multifunction tester at the periodic inspection; permanent earth monitoring on hazardous-area equipment. A measured value that trends, but it is part of the statutory periodic installation test; convert the interval only where permanent earth monitoring is fitted.
- Condition that replaces the interval
- Loop impedance above the maximum for the protective device, or continuity above 0.1 ohm on a bond
- Reading that proves it
- Earth fault loop impedance (ohms), continuity resistance
- Why the interval stays
- A measured value that trends, but it is part of the statutory periodic installation test; convert the interval only where permanent earth monitoring is fitted.
- Evidence an auditor accepts
- Test record per circuit with the measured impedance against the maximum
- First move
- Record the maximum permitted value beside each measured one; a reading without its limit is not evidence.

ISO 55001:2014 9.1 Monitoring, measurement, analysis and evaluationThe organization decides what is to be monitored and measured, which methods of monitoring, measurement, analysis and evaluation will give valid results, when monitoring and measuring take place, and when results are analysed and evaluated. It assesses and reports on how the assets perform, on how asset management perf...
ISO 55001:2014 8.1 Operational planning and controlThe organization plans, carries out and controls the processes needed to satisfy requirements and to deliver three things: the asset management plans set out under 6.2, the actions on risks and opportunities decided under 6.1, and the preventive and corrective actions decided under clauses 10.1 and 10.2. It does so by ...
ISO 55001:2014 6.2.2 Planning to achieve asset management objectivesThe organization joins up its planning for asset management objectives with the rest of its planning, including finance, human resources and other support functions. It sets up, documents and maintains asset management plans that state the method and criteria for making decisions, the processes and methods for managing...
ISO 55001:2014 8.2 Management of changeBefore any planned change is made, whether temporary or permanent, that could affect whether the asset management objectives are met, its risks are assessed, and the organization makes sure those risks are handled as 6.1 and 6.2.2 require. It controls changes it has planned and reviews the consequences of changes that ...
ISO 55001:2014 10.3 Continual improvementThe organization keeps making both its asset management and its system for it more suitable, more adequate and more effective.
ISO 45001:2018 8.1.3 Management of changeThe organization sets up processes to put in place, and keep under control, planned changes, temporary or permanent, that affect OH&S performance. These include: new products, services and processes, or alterations to existing ones (such as where workplaces are and what surrounds them, how work is organized, working co...
