Electrical testing laboratory · Resolution No. 323 · O‘z DSt 3410:2019 · Uzbekistan
Electrical Testing Laboratory approval in Uzbekistan: preparation under Resolution No. 323
We connect the scope of electrical tests, procedures, instruments, personnel qualifications and technical records into one working system and prepare the ETL for assessment.
Standart Consult performs preliminary diagnostics, develops a justified scope, checks whether methods are supported by equipment, prepares the technical passport and procedure documents, trains personnel and supports resolution of findings. The search term “ETL attestation” is retained as a commonly used name for this service.
Current procedure under Resolution No. 323
Scope based on the ETL’s actual capabilities
Methods linked to instruments
Personnel and records prepared
Support for resolving findings
Comprehensive preparation
Preparing the ETL to demonstrate competence in practice
Approval is not the purchase of a document folder. The commission assesses whether the laboratory can perform every declared type of test using an applicable method, suitable instrument, competent employee and reproducible technical records.
- we determine whether approval is the appropriate procedure for your laboratory;
- we develop an electrical testing scope without unsupported items;
- we match methods, ranges, instruments and auxiliary equipment;
- we prepare the list of methods, procedure documents and technical passport;
- we prepare personnel to demonstrate work and support corrective actions.
Result for the customer
An ETL ready to demonstrate its declared capabilities
ScopeTypes of tests and ranges are supported by methods, instruments and personnel.
DocumentsThe technical passport, procedures, journals and reports reflect actual work.
EquipmentPurpose, ranges and metrological status are confirmed by records.
PersonnelEmployees understand methods, safety, records and the distribution of responsibilities.

The key ETL linkage
How we connect the test, method, instrument and evidence
| Area | What is checked | Methodological basis | Equipment and records |
|---|---|---|---|
| Insulation resistance | Objects, test voltage, ranges, conditions and result criteria. | Applicable standards and an approved measurement procedure. | A megohmmeter with suitable ranges, metrological documents, a working record and report. |
| Earthing systems | Measurement diagram, site conditions, connection method and traceability of the result. | Measurement procedure and regulatory requirements for the relevant type of electrical installation. | An earth resistance tester, auxiliary equipment, diagram, journal and report. |
| Phase-to-neutral loop and protective measures | Applicability of the method, instrument range, input data and the link between the result and protection assessment. | Current requirements and a procedure for the relevant electrical installation. | A circuit parameter tester, primary records, calculations and a conclusion form. |
| High-voltage tests and other specialized work | Whether the declared test is supported by equipment, safety measures and personnel competence. | Specialized standards and procedures for the specific equipment and voltage class. | A test set, control and protective devices, confirmation of suitability, journals and reports. |
Personnel and safety
Personnel competence must match the declared work
For an ETL, attaching certificates is not enough. During assessment, employees must demonstrate knowledge, practical skills and the ability to perform work using the declared methods.
- relevant education, training and experience for the area of work;
- clear allocation of responsibility for tests, control and reporting;
- electrical safety groups appropriate to the role, voltage class and nature of work;
- personal records, training records and knowledge-test records;
- readiness to demonstrate a control test or measurement.
No generic promises
Group IV or V is not automatically assigned to every employee
The required group is determined by actual duties, voltage, working conditions and applicable rules. We review personnel documents against the specific ETL scope and do not replace analysis with a template statement.
Discuss the personnel structure →Typical risks
Why an ETL receives findings
Findings usually arise not from one missing document, but from a lack of linkage across the laboratory’s entire system.
- the scope includes work not supported by a procedure or instrument;
- the measuring instrument’s range and accuracy do not cover the declared method;
- primary records, calculations or links to the final report are missing;
- metrological status and equipment suitability are not confirmed for all instruments;
- personnel cannot demonstrate the sequence of the test;
- documents describe another laboratory’s processes.
Why templates are not enough
The commission assesses your ETL, not text from a ready-made package
Documents must reflect your test objects, methods, instruments, personnel and safety rules. We adapt the system to actual operations and check before assessment whether it works in practice.
Check the risks for your ETL →New ETL
First define the scope and technical need, then make purchases and prepare documents.
Operating ETL
We identify gaps between methods, instruments, reports and actual records.
After assessment
We review findings and prepare corrective actions with supporting evidence.
How we work
How ETL preparation with Standart Consult is organized
1
Initial assessment
We clarify the ETL’s purpose, types of tests, personnel, instruments and document status.
2
Preparation plan
We determine the scope, missing methods, equipment, documents and records.
3
Development and implementation
We prepare the package, train employees and verify practical performance of the work.
4
Support
We assist with submission, assessment and resolution of identified nonconformities.
Submission support
We help prepare documents and support submission of the application for ETL approval
The application is submitted on behalf of the applicant through a Public Services Center, the Single Portal of Interactive Public Services or the national “Technical Regulation” information system. The main challenge is not sending the questionnaire, but preparing a correct scope, list of methods, procedure documents, technical passport and evidence of readiness.
Standart Consult checks completeness, helps complete the questionnaire and prepare attachments, prepares the ETL for assessment of technical competence at the laboratory and organizes work to resolve findings. The personal account, identification and electronic signature remain with the customer — we support the process without replacing the applicant.
Three groups of documents under Resolution No. 323
- list of test methods and/or types of measurement;
- laboratory procedure documents;
- technical passport containing information on the ETL and equipment;
- additional evidence of readiness, where necessary;
- a questionnaire and attachments consistent with one another.

Practical specialization
Why Standart Consult is suitable for ETL preparation
Working at the intersection of electrical testing, metrology and laboratory documentation
We treat the ETL as one system: the scope, methods, instruments, conditions, personnel, safety and technical records must support one another.
- preparation of electrical testing and other testing laboratories;
- approval, accreditation, O‘z DSt 3410:2019 and ISO/IEC 17025;
- analysis of standards, methods and equipment conformity;
- development of test and measurement procedures, journals, worksheets and reports;
- corrective actions and evidence that findings have been resolved.
Important distinction
ETL approval, accreditation and authorization of an electrical installation are different procedures
Electrical Testing Laboratory Approval
Confirmation of the laboratory’s technical competence in the declared scope under a national procedure.
Laboratory accreditation
Confirmation of competence within the accreditation system, generally against ISO/IEC 17025.
Authorization of an electrical installation
This procedure concerns the customer’s facility. ETL reports may be used as work results, but they do not replace the status of the laboratory itself.
FAQ
Frequently asked questions about electrical testing laboratory approval
ETL approval confirms the technical competence of an electrical testing laboratory in its declared scope of tests and measurements. The phrase “ETL attestation” is still used in search and business language, but this page concerns the current procedure for approval of technical competence.
The current public-service procedure is established by Resolution No. 323 dated 24 June 2026, effective from 25 June 2026. General requirements for the technical competence of testing laboratories are established by O‘z DSt 3410:2019. The former Resolution No. 456 ceased to be effective on 25 June 2026.
Not always. The ETL’s purpose, customers, types of tests and participation in mandatory conformity assessment must first be determined. Depending on its objective, the laboratory may need approval, accreditation or another form of confirmation. During the initial assessment, we help identify the appropriate route.
The regulation provides for three main groups of documents: a list of test methods and/or types of measurement defining the declared scope; laboratory procedure documents; and a technical passport containing information on the laboratory, equipment and test and measurement instruments used.
Personnel must have demonstrated competence specifically for the declared scope. Education, training, experience, allocation of functions, personal records and ability to demonstrate work are checked. The electrical safety group must correspond to the nature of work, voltage class and employee role; assigning one universal group to every ETL is incorrect.
The equipment set is determined by the scope and methods: measuring instruments, test equipment and auxiliary equipment must support the declared work. For each item, range, accuracy, condition, verification or calibration are checked; for test equipment, evidence of suitability and operating records are checked where applicable.
Yes. It is useful to define the scope, methods, ranges and required characteristics first. This reduces the risk of buying instruments that do not cover the declared tests, have an unsuitable range or create unnecessary costs.
Not if they are not linked to actual tests. The commission assesses your laboratory: methods, instruments, personnel, conditions, primary records and reports. A generic template can become a source of findings if it describes processes that do not exist in the ETL.
Yes. Work begins with diagnostics of the scope, personnel, premises and equipment. The technical passport, list of methods, procedure documents, journals, worksheets, report forms and implementation plan are then developed.
Each nonconformity must be reviewed, its cause identified, and corrective actions and evidence of implementation prepared. Under Resolution No. 323, nonconformities specified in the assessment report may be resolved within a period of up to three months.
Under the regulation, document completeness is reviewed within three working days; after payment, the commission is formed within no more than two working days, and the laboratory assessment takes no more than ten working days. The public fee depends on the number of parameters in the scope. The time and cost of consulting preparation depend on the breadth of the scope and the ETL’s actual readiness.
The official decision is made by the authorized body. Standart Consult prepares the scope, documents, personnel and evidence of competence and supports submission and resolution of findings, but does not replace the public assessment and cannot guarantee the authority’s decision.
