Benefits of our on-site testing service
Minimise operational disruption
Conduct testing at your location, reducing the need to dismantle or transport large, fixed, or integrated equipment and assets.
Test under operating conditions
Evaluate equipment within its actual installation, electrical supply, and surrounding operating environment through on-site measurement.
Support technical decisions
Use objective on-site measurements to investigate faults, identify potential root causes, and plan appropriate corrective actions.
How TÜV SÜD can help with on-site testing
Many products and systems can be evaluated in a laboratory or test chamber. However, large, fixed, integrated, or operational assets may be difficult to transport or may need assessment under actual site conditions.
Our on-site testing service provides a practical way to evaluate equipment, installations, and facilities where they are installed and used. Our specialised in-situ team uses mobile, calibrated equipment to conduct localised testing, inspection, and measurement activities.
On-site assessments can help identify technical issues that may only be visible in the operating environment. These may include electromagnetic interference, electrical safety concerns, power quality disturbances, abnormal heat patterns, leakage current, equipment faults, and other site-specific risks.
Our experts work with you to understand your equipment, operating environment, applicable requirements, and project objectives before defining an appropriate on-site testing and measurement scope.
From initial planning and measurements to technical evaluation and reporting, TÜV SÜD provides independent support throughout the assessment process.
Applications
Our on-site testing and measurement services can be used for:
- Large machines: Equipment that is difficult or impractical to transport to a laboratory
- Railway and vehicles: Specialised, commercial, or operational vehicles requiring assessment at a designated location
- Electrical and electronic equipment: Standalone or integrated equipment installed at your site
- Facility floors and critical environments: Including data centres, corporate premises, production floors, and factories
On-site testing and measurement services
EMI and EMF measurement
Electromagnetic interference (EMI) and electromagnetic field (EMF) measurements evaluate electromagnetic emissions and field levels in the operating environment. Results can contribute to troubleshooting, risk evaluation, and conformity activities based on applicable requirements.
Field electrical testing and measurement
Our specialists conduct field electrical testing and measurements on equipment and installations under site conditions. The assessments provide technical information on electrical safety, operating behaviour, and system condition.
Fixed equipment testing
Our fixed equipment testing can cover dead, semi-live, and live test sequences in accordance with applicable SS 638 requirements.
Depending on the agreed scope, testing may include visual inspections, continuity, insulation resistance, polarity checks, thermal imaging, earth-loop impedance, isolation and switching device verification, residual current device operation, and prospective fault current testing.
Lightning protection system measurements and validation
Measurements and validation help assess whether a lightning protection system has been installed and maintained in accordance with relevant design requirements and applicable standards. The assessment can contribute to verification of system integrity and continued effectiveness.
Power quality measurement
Power quality measurement evaluates electrical supply characteristics that may affect equipment performance and reliability. Depending on project requirements, measurements can cover harmonic distortion, voltage variations, frequency stability, and transient events.
Factory Acceptance Test (FAT) verification
TÜV SÜD can provide independent Factory Acceptance Test (FAT) verification. Our experts review the agreed test scope, witness relevant test activities, and assess results against defined specifications, acceptance criteria, and applicable requirements.
Thermal scanning
Thermal scanning uses infrared imaging to identify abnormal heat patterns that may indicate loose connections, overloaded components, unbalanced loads, deterioration, or other developing faults.
Early identification can contribute to preventive maintenance and reduce the risk of unplanned interruption.
Leakage current verification
Leakage current measurements evaluate unintended current flowing from electrical equipment or installations. Verification can contribute to electrical safety assessment, fault investigation, and conformity with relevant limits and requirements.
Threat assessment
A threat assessment reviews potential technical risks associated with the equipment, installation, and operating environment. The findings help you prioritise further investigation, testing, or mitigation measures according to the identified risk.
Why choose TÜV SÜD for on-site testing?
Our experts bring decades of testing and measurement experience, supported by international accreditations and local expertise. We understand technical standards and regulatory requirements applicable within Singapore and across international markets.
Our independent approach and testing capabilities allow us to assess complex equipment, installations, and operating environments and provide objective technical findings for safety assessment, troubleshooting, maintenance verification, and compliance activities.
Frequently asked questions
What is an on-site testing service?
An on-site testing service assesses equipment, installations, or facilities at the location where they are installed or used. It is suitable for large, fixed, integrated, or operational assets that are difficult to transport or need assessment under actual site conditions.
When is on-site testing needed instead of laboratory testing?
An on-site testing service can be suitable when equipment is large, fixed, integrated, operational, or difficult to transport to a laboratory. It is also useful when equipment needs to be evaluated within its actual installation, electrical supply, and operating environment.
What can fixed equipment testing include?
Depending on the agreed scope, fixed equipment testing can include visual inspection, continuity, insulation resistance, polarity, thermal imaging, earth-loop impedance, isolation and switching device verification, residual current device operation, and prospective fault current testing.
Who needs on-site testing services?
On-site testing services can be used for equipment and installations that are difficult to assess effectively through laboratory testing alone or need evaluation under actual site conditions.
Applications described in the brief include large machines, railway and operational vehicles, electrical and electronic equipment, data centres, corporate premises, production floors, and factories.
