What Are Electrical & Instrumentation Inspection Services?
Electrical & Instrumentation Inspection Services involve the systematic verification of electrical installations, field instruments, control systems, protection devices and associated documentation.
The purpose is to determine whether the inspected systems conform to approved engineering requirements and are suitable for safe operation.
Electrical inspection generally focuses on power generation, distribution, protection, cabling, switchgear, panels, motors, earthing, lighting and associated electrical equipment.
Instrumentation inspection focuses on devices and systems used to measure, transmit, display and control process variables such as:
- Pressure.
- Temperature.
- Flow.
- Level.
- Vibration.
- Speed.
- Position.
- Weight.
- Density.
- Conductivity.
- Gas concentration.
- Chemical composition.
Instrumentation systems may also provide signals to programmable logic controllers, distributed control systems, supervisory control and data acquisition systems, safety instrumented systems, emergency shutdown systems, alarm systems and fire and gas systems.
Consequently, E&I inspection is not limited to checking whether equipment has been installed. It also verifies identification, compatibility, accessibility, protection, documentation, testing, calibration status and functional performance.
Why Electrical and Instrumentation Integrity Matters
Industrial facilities depend on reliable electrical power and accurate process information. Even a small installation defect can affect an entire production system.
For example, a loose cable termination may generate heat and eventually cause equipment failure or fire. Similarly, an incorrectly ranged pressure transmitter may send inaccurate information to the control system. As a result, operators may make decisions based on incorrect process conditions.
Common E&I failures may be caused by:
- Loose or incorrectly torqued electrical connections.
- Incorrect cable sizing.
- Damaged insulation.
- Inadequate cable protection.
- Poor earthing and bonding.
- Incorrect circuit identification.
- Reversed polarity.
- Incorrect instrument range or calibration.
- Improper impulse-line installation.
- Blocked instrument tubing.
- Incompatible hazardous-area equipment.
- Incorrect Ex cable glands.
- Missing stopping plugs.
- Incomplete loop testing.
- Incorrect alarm or trip settings.
- Unverified safety interlocks.
- Poor documentation control.
- Unapproved modifications.
Moreover, facilities operating with flammable gases, vapours, mists or combustible dust require additional controls. Electrical equipment in these environments must be selected, installed and maintained according to the hazardous-area classification and the applicable explosion-protection requirements.
IEC 60079-14:2024 addresses the design, selection, installation and initial inspection of Ex electrical installations, while IEC 60079-17:2023 addresses inspection and maintenance requirements for electrical installations in explosive atmospheres.
Therefore, competent E&I inspection is an essential part of industrial safety, quality assurance, commissioning and asset integrity management.

- IEC 60079-10-1 for classification of explosive gas atmospheres.
- IEC 60079-10-2 for classification of combustible dust areas.
- IEC 60079-14 for design, selection, installation and initial inspection.
- IEC 60079-17 for inspection and maintenance.
- IEC 60079-19 for repair, overhaul and reclamation.
- IEC 60079-11 for intrinsic safety.
- Other protection-specific parts where applicable.
IEC 60079-0:2026 specifies general construction, testing and marking requirements for Ex equipment and components. Meanwhile, IEC 60079-10-1 addresses gas-area classification, and the 2026 edition of IEC 60079-10-2 addresses combustible-dust area classification.
IECEx
IECEx is an international conformity-assessment system established by the IEC for equipment, services and personnel associated with explosive atmospheres. It is not a single technical standard. Instead, it operates using relevant IEC standards and certification schemes.
During an IECEx-related inspection, documentation review may include:
- IECEx Certificate of Conformity.
- Quality-assessment information.
- Equipment marking.
- Certificate schedules.
- Approved drawings.
- Conditions of certification.
- Special conditions of use.
- Installation instructions.
- Repair-facility documentation.
An installation inspection does not itself create an IECEx product certificate. Product and personnel certification must be issued through the applicable IECEx scheme and authorised certification bodies.
ATEX
ATEX Directive 2014/34/EU covers equipment and protective systems intended for use in potentially explosive atmospheres within the European Union market. It defines essential health and safety requirements and conformity-assessment procedures for covered products.
Although Mozambique is not an EU member state, ATEX requirements may still appear in:
- International oil and gas projects.
- European equipment specifications.
- EPC contractor requirements.
- Manufacturer documentation.
- Client engineering standards.
- Imported equipment packages.
Where ATEX is contractually specified, inspection may verify product marking, category, conformity documentation, notified-body information where applicable, installation suitability and consistency with the hazardous-area classification.
CompEx
CompEx is an internationally recognised competency scheme for people working in explosive atmospheres. It is a personnel-competence framework rather than an equipment-certification standard.
Depending on the project, clients may require relevant CompEx qualifications for personnel performing or supervising hazardous-area installation, inspection or maintenance.
Before mobilisation, the required personnel competence should be agreed according to:
- Inspection scope.
- Hazard type.
- Equipment type.
- Inspection grade.
- Applicable standards.
- Client specifications.
- Project competency matrix.
Planning an Ex inspection campaign? Request a scope review from TechInspecta before mobilisation so that documentation, access, competence and reporting requirements can be defined correctly.

This integrated approach is particularly valuable during commissioning, shutdowns and multidisciplinary asset-integrity projects.
Project-Specific Inspection Planning
Every facility has different equipment, risks and contractual requirements. Therefore, we develop the inspection scope according to the client’s systems, standards and priorities.
Clear Technical Reporting
Our reporting approach focuses on usable information. Findings are linked to equipment tags, locations, requirements and corrective actions.
Where appropriate, reports can include photographs, punch classifications, inspection status and recommendations.
Support Across the Asset Lifecycle
TechInspecta can support:
- Vendor and procurement inspection.
- Construction QA/QC.
- Installation inspection.
- Pre-commissioning.
- Commissioning.
- Operational inspection.
- Shutdown inspection.
- Maintenance verification.
- Modification projects.
- Decommissioning preparation.
Focus on Safety and Compliance
Safety is integrated into inspection planning, site execution, testing and reporting.
Moreover, we recognise the boundaries between inspection, testing, calibration, engineering approval and formal certification. This helps clients receive technically accurate deliverables without misleading conformity claims.

Every inspection delivered to internationally recognised frameworks.
All TechInspecta inspections are conducted in full compliance with the standards mandated by the world’s leading regulatory bodies and industry authorities:
Electrical & Instrumentation Inspection Services verify the installation, condition, documentation and functionality of electrical equipment, field instruments and control systems. The service helps determine whether the systems meet approved drawings, technical specifications, safety requirements and applicable standards.
Inspection should be performed during material receipt, construction, installation, pre-commissioning, commissioning, maintenance, shutdowns and periodic asset-integrity reviews. Early inspection is particularly valuable because defects can be corrected before systems are energised or concealed.
TechInspecta supports industrial projects across Mozambique, subject to project scope, mobilisation requirements, site access and personnel availability. Services can be arranged for Maputo, Matola, Pemba, Palma, Afungi, Nacala, Beira, Tete, Temane and other project locations.
The inspection scope may include switchgear, motor control centres, transformers, generators, motors, electrical panels, distribution boards, cables, junction boxes, lighting, emergency power, battery systems, earthing, bonding and lightning-protection systems.
Instrumentation inspection may cover pressure, temperature, flow, level, vibration and analytical instruments. It may also include control valves, positioners, gas detectors, fire detectors, junction boxes, PLC systems, DCS systems, SCADA systems, emergency shutdown systems and safety instrumented systems.
Yes, hazardous-area inspection can be included in the agreed scope. The inspection may verify equipment marking, zone suitability, Equipment Protection Level, gas or dust group, temperature class, cable glands, stopping plugs, enclosure integrity, certificates, earthing and installation condition.
The required inspector competence and inspection grade should be defined before mobilisation.
IECEx is an international certification system for equipment, services and personnel associated with explosive atmospheres. ATEX refers to European Union requirements for equipment and protective systems intended for potentially explosive atmospheres. CompEx is a personnel-competence scheme for people working in hazardous areas.
Therefore, they have related but different purposes.
No. An installation inspection report does not create an IECEx or ATEX product certificate.
IECEx certificates must be issued through the applicable IECEx certification scheme. Likewise, ATEX product conformity depends on the manufacturer’s conformity-assessment route and required documentation.
Inspection can verify whether available certificates and installed equipment are consistent with project requirements.
The scope may include calibration inspection, calibration witnessing, field verification or review of calibration certificates.
Where accredited laboratory calibration is required, the work must be completed by a laboratory holding the appropriate accreditation and technical scope.
A loop check verifies the signal path from the field instrument through the cabling and control system to the final indication or output.
It may verify engineering units, scaling, alarms, trip setpoints, valve response, input/output assignment and fail-safe action. However, a loop check does not replace calibration unless calibration is specifically included.
Yes. Commissioning support may include document review, installation verification, test witnessing, loop checks, functional testing, cause-and-effect testing, punch listing and corrective-action verification.
Applicable references may include the IEC 60364 series, IEC 60079 series, IEC 61511, IEC 60529, IEC 60204-1, IEC 61439, IEC 62305, ISO/IEC 17020 principles, ATEX requirements, IECEx documentation, CompEx competency requirements and client specifications.
The contractually adopted editions should always be confirmed before inspection.
