Overview
Third party inspection (TPI) is an independent check that goods, equipment or an installation meet what was agreed: the relevant standard, the purchase specification, the approved drawings and the quality assurance plan. The inspector works for neither the seller nor, in the commercial sense, the buyer. Their job is to give both sides a factual record they can rely on.
Aaditech Inspections & Services has carried out third party inspection since 2012. We are accredited by the National Accreditation Board for Certification Bodies (NABCB) as a Type A inspection body under ISO/IEC 17020:2012, certificate IB 024, valid to 03 March 2030. Type A is the strictest independence category in the standard. It means we have no design, manufacturing, supply or maintenance interest in anything we inspect.
If you are looking for a quick summary of how to appoint us for a specific order, see our third party inspection agency page. This page explains the service in more depth.
Note: Our NABCB accreditation covers electrical equipment only (IAF scope 19). We also inspect other products, such as steel, building materials and mechanical items, on request. Those inspections sit outside our accredited scope, and our reports state this.
What we inspect
Within our accredited scope, we carry out stage-wise and final inspection of:
| Product family | Typical inspection points |
|---|---|
| Wires, cables and conductors | Construction, dimensions, conductor resistance, insulation thickness, marking, routine and acceptance tests |
| Energy meters | Accuracy checks, sealing, marking, acceptance tests per the purchase specification |
| Transformers | Routine tests witnessed at works, ratio, losses, insulation resistance, oil quality |
| Switchgear and controlgear | Assembly checks, functional and dielectric tests, wiring and labelling |
| Lamps, LEDs and ballasts | Photometric and electrical parameters, marking, safety checks |
| IS 302 household appliances | Safety-related construction and routine tests |
| Capacitors and AC motors | Electrical performance, routine tests, nameplate data |
| Insulators, insulating oils and mats | Visual and dimensional checks, electrical tests, sampling |
| Wiring accessories | Construction, marking, mechanical and electrical checks |
| Distribution apparatus | Installation and maintenance inspection on site |
Who it’s for
- Utilities, public sector undertakings and EPC contractors who need independent inspection before accepting material against a contract.
- Manufacturers whose customers or tender terms require inspection by an accredited third party.
- Importers and traders who want assurance on goods before they are shipped or released.
- Facility owners checking that distribution equipment has been installed and maintained correctly.
Our process
- Scope and contract review. We study the purchase order, technical specification, applicable Indian or international standards and the approved quality plan, and confirm the inspection is within our competence and accreditation.
- Inspection plan. We agree hold and witness points, sampling, test methods and acceptance criteria with the client before work starts.
- Stage-wise inspection. Where required, our inspector visits at agreed stages, such as raw material, in-process and routine testing, so defects are caught before they are built into the finished product.
- Final inspection. We draw samples from the finished lot, witness tests, check calibration of the test equipment used and verify marking, packing and documents.
- Reporting. We issue an inspection report and, where applicable, an inspection certificate that records what was checked, the results and any non-conformities.
- Follow-up. If a lot is rejected or held, we can re-inspect after the manufacturer has taken corrective action.
Standards & references
- ISO/IEC 17020:2012: requirements for the operation of bodies performing inspection, including impartiality, independence and competence.
- NABCB accreditation for inspection bodies, operated under the Quality Council of India.
- The Indian Standards (IS) and IEC standards named in each purchase specification, together with the customer’s own technical specification and quality assurance plan.
Why Aaditech
- Regulatory background. Aaditech was promoted by former Directors of the Bureau of Indian Standards. Our CEO, Mr B.K. Jain, headed the BIS electrical laboratory and later served as Joint Director at the Delhi Electricity Regulatory Commission.
- Type A independence. We have no stake in the products we inspect, which matters when a decision to accept or reject a lot carries real cost.
- Electrical depth. Our accredited scope is electrical equipment, which is also where our team’s experience is strongest.
- Recognised elsewhere. NTPC has approved us as a third-party agency for authenticating tender documents, and the Bureau of Energy Efficiency appointed us as an Independent Agency for Monitoring & Evaluation (IAME) of star-rated products in 2021.
