Summary: Production Audit (Analysis of the State of Production) for EAC Certification
- Purpose of the Factory Inspection: The production audit (Russian: Анализ состояния производства) assesses on-site at the manufacturing facility whether the manufacturer possesses the operational, personnel, and metrological infrastructure required to ensure the stable, repeatable conformity of certified products during ongoing serial manufacturing across the full certificate lifecycle (up to 5 years).
- Statutory Requirement under Scheme 1c: The on-site audit is a mandatory requirement for EAC Serial Certification under Scheme 1c for safety-critical industrial equipment (machinery, pressure vessels, explosion-proof apparatus, low-voltage systems, and personal protective equipment). For batch or single-unit certifications (Schemes 3c, 4c) as well as EAC Declarations, statutory on-site factory audits are not required.
- Binding Legal & Standardization Framework: The process is governed by EEC Council Decision No. 44/2018 (Section IX, Clauses 58–71), the methodological standards of GOST R 54293-2020, and, for explosion-proof equipment, GOST R ISO/IEC 80079-34-2013.
- Clarification on ISO 9001 Certification: Holding an ISO 9001 quality management certificate does not exempt the manufacturer from an on-site audit under Scheme 1c. However, it provides auditors with a structured documentation baseline and significantly shortens on-site audit duration.
- Reuse of Audits (The 12-Month Rule): Under Decision No. 44/2018, the positive results of a completed production audit can be formally recognized for up to 12 months for subsequent certification procedures conducted by the same certification body, provided comparable product families and production lines are involved.
- Legal Risks of "Remote Audits": Following the expiration of temporary pandemic-era concessions, purely remote or video-streamed audits have no permanent legal standing in regular EAEU certification. Unlawfully conducted remote audits trigger retrospective certificate revocations during regulatory reviews by accreditation agencies (e.g., Rosakkreditatsiya).
- Sanctions & Visa Compliance for Global Manufacturers: In light of travel barriers, visa restrictions for inspectors, and Western embargoes, Schmidt & Schmidt conducts factory audits for international manufacturers via accredited expert teams from Kazakhstan—fully accredited, mobile, and in strict compliance with Regulation (EU) No 833/2014 and US export controls.
What Is an EAC Production Audit and Why Is It Indispensable?
Under the technical regulatory framework of the Eurasian Economic Union (Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan), one-off laboratory testing of a single sample prototype is legally insufficient to obtain a five-year serial approval. The production audit verifies the industrial foundation required for continuous manufacturing consistency.
While an accredited testing laboratory establishes during type testing whether a submitted prototype satisfies biomechanical, thermal, or electrical safety targets, the production audit determines whether the production plant can reliably manufacture thousands of subsequent units with identical safety characteristics.
Significance for International Equipment Manufacturers: Industrial manufacturers frequently operate modular assembly lines, outsource safety-critical operations to specialized sub-suppliers, and update engineering designs during ongoing product lifecycles. During an EAC factory audit, auditors inspect an active manufacturing order across the entire value chain—from incoming raw material inspection and specialized welding or potting processes to end-of-line verification. Discrepancies between manufacturing records and the technical file submitted for the EAC Certificate will stall or invalidate the certification procedure.
Legal Foundations and Relevant Technical Regulations
The mandate for an on-site factory inspection during serial certification is directly established in the sectoral Technical Regulations (TR CU / TR EAEU). Procedurally, the audit is governed by EEC Council Decision No. 44/2018 (Section IX) and the methodological testing standard GOST R 54293-2020 ("Conformity assessment. Analysis of the state of production in certification procedures"):

Audit Scope: The Traceability Pathway under GOST R 54293
The audit is conducted by accredited assessors from the certification body in accordance with a formally approved audit program. Assessors trace the material and information flow of an active production run:
| Audit Domain | Physical Target in the Plant | Mandatory Verification Records |
|---|---|---|
| Infrastructure & Working Environment | Facility conditions, ambient temperature, humidity, cleanliness, and material routing to prevent component mix-ups. | Plant layouts, architectural drawings, fire safety concept, facility maintenance logs. |
| Incoming Inspection & Supplier Control | Verification of raw materials, feedstock, and purchased parts; physical segregation and control of quarantine areas. | Material test certificates (e.g., EN 10204-3.1), goods receipt inspection logs, vendor ratings, non-conformance reports. |
| Special Technological Processes | Control and validation of processes whose outcomes cannot be verified non-destructively on the finished unit (welding, potting, heat treatment). | Welding procedure specifications (WPS/WPQR to ISO 15614), welder qualifications (ISO 9606), NDT test records, potting logs. |
| Inspection & Measuring Equipment | Metrological traceability and suitability of all measuring devices used for safety tolerances and final quality release. | Calibration certificates (DAkkS, SAS, UKAS, NIST, etc.), verification records, metrology index, calibration schedules, calibration stickers. |
| Traceability | Unbroken traceability of a sampled serial number back to raw material melts, subassemblies, and batch records. | Job routings, traveler sheets, ERP logs, mill test reports, heat tracking sheets, batch records. |
| End-of-Line Verification & Acceptance | Proper execution and recording of routine (unit-by-unit) safety tests defined in the inspection plan. | Routine test records (dielectric strength, earth continuity, hydrostatic pressure test), quality release stamps, test procedures. |
| Marking & Packaging | Nameplate layout compliance with mandatory data fields, application of the EAC Mark, and transit protection. | Nameplate samples, labeling work instructions, packaging procedures, climate/moisture protection. |
| Complaints & CAPA | System for recording marketplace complaints, root cause analysis, and implementation of corrective/preventive actions. | Complaints log, 8D reports, CAPA standard operating procedures, documentation of implemented process corrections. |
Case Study: Audit for Explosion-Proof Equipment under TR CU 012/2011
During the EAC Certification of explosion-proof equipment (motors, pumps, sensors, control panels) under TR CU 012/2011 for refineries, chemical processing plants, or pipeline compressor stations, the factory audit is among the most demanding technical assessments in EAEU conformity evaluation.
Supplementary Standards: In addition to GOST R 54293-2020, auditors mandate compliance with GOST R ISO/IEC 80079-34-2013 (the international standard for Ex quality systems, equivalent to the European ATEX QA Notification under Directive 2014/34/EU). The on-site inspection takes two full working days and is conducted by a two-person team: a lead QA auditor assessing the management system and a technical Ex-specialist examining explosion-protection engineering features on the line.
1. Incoming Inspection & Prevention of Unauthorized Revisions
The facility walkthrough begins in the receiving warehouse. Assessors audit:
- verification of incoming enclosures, flameproof joints, cable glands, elastomeric O-rings, and potting compounds against the specifications in the approved design dossier;
- traceability of critical electronic safety components (e.g., Zener barriers, safety capacitors, thermal fuses for intrinsic safety Ex i);
- physical quarantine storage: rejected or pending materials must be physically segregated and secured to prevent accidental introduction into Ex production.
2. Assembly, In-Process Controls & Explosion-Protection Parameters
The core focus is the assembly of explosion-protected equipment:
- Flameproof Joint Measurement: For flameproof enclosures (Ex d), auditors verify measurement tools, gap gauges, and records verifying flamepath dimensions and surface roughness;
- Encapsulation Processes (Ex m): Inspection of resin mixing ratios, curing temperatures, degassing parameters, and void-free verification;
- Torque Monitoring: Calibration records for torque wrenches applied to enclosure fasteners, terminal blocks, and grounding studs;
- Personnel Qualifications: Training records and certifications verifying operator competence in hazardous area equipment assembly.
3. Routine Tests, Nameplate Layout & Marking
Every Ex unit must undergo documented routine tests before dispatch. Auditors witness live verification on the test bench:
- overpressure testing of flameproof enclosures to verify pressure-containment integrity;
- dielectric withstand (high-voltage) tests and protective earth continuity measurements;
- nameplate compliance: alongside the EAC Mark, the plate must display the official Ex marking, full protection designation (e.g., 1Ex d IIC T4 Gb X), ambient temperature range, and certificate number via permanent engraving or etching.
Multi-Site Manufacturing & Outsourced Processes (Subcontractors)
Modern industrial manufacturers frequently operate distributed production networks (e.g., machining in Austria, control cabinet assembly in Germany, final integration in Hungary or Poland) or outsource key manufacturing steps to sub-tier suppliers.
Requirements under EEC Decision No. 44/2018 (Section IX):
The applicant is legally obligated to submit a comprehensive manufacturing site matrix of all facilities involved in the production process at the time of application. Concealing outsourced manufacturing facilities to reduce audit expenses renders the resulting certificate null and void.
- Representative Sampling of Sites: If a manufacturer maintains multiple plants operating under an identical quality management system and comparable technologies, Decision No. 44 permits representative sampling of sites during initial certification, paired with a documented rotation plan to audit remaining plants during subsequent annual surveillance inspections.
- Critical Outsourced Operations: If critical safety operations (such as boiler shell welding or Ex encapsulation) are outsourced, the certification body may mandate an on-site audit of the subcontractor facility unless the main plant's incoming quality controls independently verify process consistency.
The Remote Audit Myth: Legal Risks of Pure Online Inspections
Certain market brokers promote "remote audits" conducted solely via webcam or video conferencing to eliminate travel expenses. For international exporters, this approach entails major liability and cancellation risks.
Legal Reality under EAEU Law:
Temporary derogations enacted during the COVID-19 pandemic have expired. Under EEC Council Decision No. 44/2018, an analysis of the state of production is legally defined as a physical, on-site factory inspection.
Can an ISO 9001 Certificate Replace the EAC Factory Audit?
Quality management teams often assume that an ISO 9001 certificate issued by an accredited registrar (such as TÜV, DEKRA, BSI, or SGS) waives the requirement for an EAC factory inspection. For standard Scheme 1c certification, the on-site audit is a mandatory statutory requirement.
Nonetheless, an active ISO 9001 quality management system provides distinct operational benefits:
- Accelerated On-Site Review: Standard operating procedures, calibration indices, and training matrices already comply with international norms, reducing on-site audit duration to 1–2 days;
- Mitigation of Major Non-Conformities: The likelihood of audit failure is minimized, as operational personnel are accustomed to structured process control;
- Alternative Application under Scheme 2c: In selected technical regulations, Scheme 2c permits the assessment of a certified QMS in lieu of a production analysis—this, however, entails a separate, formal conformity assessment of the management system itself.
Sanctions & Visa Compliance for International Manufacturers: The Kazakhstan Solution
Given current geopolitical friction, disrupted flight paths, and strict visa issuance policies in Western nations, dispatching auditors from Russia or Belarus to European and international manufacturing plants is practically unviable for many companies.
Primary Challenges for Global Manufacturers:
- Visa Denials: Auditors from certain jurisdictions cannot secure business visas, or corporate compliance directives prohibit external experts from conflict regions from entering sensitive R&D and production facilities;
- Banking and Payment Blocks: Direct wire transfers for official audit fees and expert expenses to institutes in Russia or Belarus are routinely blocked under financial sanctions (Regulation (EU) No 833/2014);
- Distributor Dependency: If a local distributor acts as the applicant, the factory audit and the resulting certificates remain under their proprietary legal control.
The Compliant Solution via Schmidt & Schmidt in Kazakhstan:
Schmidt & Schmidt operates full-service offices in Almaty and Astana. As a founding EAEU member state, Kazakhstan operates a fully recognized, accredited certification infrastructure:
- Audits are conducted by state-accredited Kazakh auditors who travel internationally without visa bottlenecks;
- Contracts and financial transactions are executed in Euros directly through our German headquarters in Passau, Germany;
- Serving as an independent Authorized Representative, we hold your certification assets neutrally, ensuring certificates remain valid independent of any single commercial distributor.

Audit Workflow and Findings: What Happens If Deficiencies Are Found?
The audit concludes with a formal debriefing between the audit team, plant management, and quality directors. The findings are recorded in an official Audit Report (*Akt o sostoyanii proizvodstva*):
1. Positive Outcome
Finding: All manufacturing and quality systems meet GOST R 54293 requirements; production ensures consistent product safety.
Next Steps: The positive report is incorporated into the certification dossier. Once successful laboratory test reports are submitted, the five-year EAC Certificate is officially registered.
2. Remediable Non-Conformities
Finding: Minor procedural gaps, incomplete work instructions, or expired calibration stickers on non-critical instruments.
Next Steps: The body establishes a deadline to resolve gaps (Corrective Action Plan / CAPA). Verification is typically documentary (e.g., updated calibration records or photographic proof).
3. Negative Outcome
Finding: Systemic breakdown of quality controls, refusal to grant access to critical production processes, or critical unresolvable design flaws.
Next Steps: The certification process is officially terminated with a formal notice of rejection. No certificate is issued.
Duration and Costs of the Production Audit
Processing schedules and costs of a production audit depend on the quantity of assembly lines, facility locations, and travel logistics:
- On-Site Duration: Typically 1 to 2 working days on-site (up to 3 days for complex industrial equipment or distributed lines);
- Preparation and Processing Time: Approximately 3 to 5 weeks covering audit program design, travel scheduling, on-site inspection, and final report drafting;
- Cost Components: Total budgets comprise certification body filing fees, expert auditor per diems, technical translation, and travel/accommodation expenses;
- Subsequent Costs: Under five-year serial certification, manufacturers must budget for annual surveillance audits (inspection control).
