Summary: Testing of Product Samples in the EAC Conformity Assessment Procedure
- Core Procedural Step: Testing representative product samples in a state-accredited testing laboratory is the mandatory substantive basis of proof for issuing EAC Certificates (Schemes 1c, 2c, 3c) and registering the majority of EAC Declarations (Schemes 3d, 4d, 6d).
- Binding Legal & Normative Framework: The sampling and assessment processes are governed by the harmonized scheme rules of EEC Council Decision No. 44/2018 (Section VI, §§ 36–42) and the competence criteria for testing laboratories under GOST ISO/IEC 17025-2019.
- Principle of the Two Standards Lists (Requirement Standard vs. Test Method): Each Technical Regulation is underpinned by two legally distinct lists of standards adopted by the EEC. Complying with a safety requirement (List 1) does not exempt the manufacturer from verifying the exact test and measurement method (List 2) through an accredited laboratory.
- Customs-Compliant Sample Import (EAEU Decision No. 130): Test samples for certification purposes must never be carried in personal luggage or imported as standard commercial goods. Formal customs clearance under dedicated customs procedure code 061 ("samples for certification testing") based on an official sampling act and a contract with the certification body is mandatory. Without this customs clearance record, the test report is legally void.
- Strict 1-Year Validity for Test Reports: When registering serial certificates and serial declarations (Schemes 3d/6d), the test report issued by the accredited laboratory must be no older than 1 year at the time of submission.
- Representative Testing Groups (Worst-Case Approach): To minimize testing costs for extensive product lines, the regulations permit grouping homogeneous items into product families. Only the model subjected to the highest operating stress (worst-case scenario) undergoes physical testing.
- Witness Testing on Manufacturer Test Benches: For heavy, immovable industrial machinery or unique custom units, tests can be conducted directly on the manufacturer's testing field under the supervision of accredited experts.
- Sanctions & Logistics Compliance for Western Exporters: Because sample shipments to Russia and Belarus are severely impaired by EU sanctions (Regulation (EU) No 833/2014) and disrupted freight corridors, Schmidt & Schmidt executes laboratory trials legally through accredited testing centers in Kazakhstan.
Significance of Sample Testing for EAEU Market Access
The testing of product samples in accredited testing laboratories forms the metrological foundation of conformity assessment in the Eurasian Economic Union (Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan). It provides objective, empirical proof that an item fulfills the mandatory safety objectives of the applicable Technical Regulations (TR CU / TR EAEU) under real-world operating conditions.
Neither European CE declarations of conformity nor inspection certificates under EN 10204 exempt a manufacturer from this statutory obligation. For safety-critical industrial and consumer goods, market surveillance authorities strictly require the submission of an officially registered test report (*Protokol ispytaniy*) issued by an accredited testing laboratory listed in the unified EAEU register.
Relevance for International Manufacturers: Western manufacturers produce to exceptional quality standards. Nevertheless, conformity assessment projects frequently fail not due to product non-compliance, but due to procedural violations: improperly imported samples, incomplete sampling acts, or contracting testing facilities that lack the requisite scope of accreditation. Schmidt & Schmidt manages the testing process from model grouping to the final, legally binding test report with complete transparency and compliance.
Accreditation of Testing Laboratories: GOST ISO/IEC 17025
Within the framework of EAC conformity assessment, testing may exclusively be performed by laboratories officially authorized by the national accreditation authorities of EAEU member states (e.g., Rosakkreditatsiya in Russia or NCA in Kazakhstan) and listed in the Unified EAEU Register of Testing Laboratories.
The technical and metrological competence of testing laboratories is governed by international quality standards:
- GOST ISO/IEC 17025-2019: General requirements for the competence of testing and calibration laboratories (ensuring international comparability, measurement uncertainty evaluation, and analytical impartiality).
- Scope of Accreditation (*Oblast akkreditatsii*): A testing laboratory may only conduct trials for those specific GOST standards explicitly enumerated in its officially registered accreditation schedule. Tests conducted outside this scope are legally void.
Standards Matrix under EAEU Law: Requirement Standards vs. Test Methods
A common methodological misconception among European engineering and QA departments is assuming that a single technical standard covers both safety requirements and verification procedures. In the EAEU regulatory system, the Commission adopts two legally separate lists of standards for each Technical Regulation:
- 1. List of Requirement Standards (*Perechen standartov s trebovaniyami*): Encompasses standards whose voluntary application confers a presumption of conformity with the essential health and safety requirements of the Technical Regulation.
- 2. List of Test Methods (*Perechen standartov s metodami issledovaniy*): Encompasses mandatory specifications for sampling procedures, test bench configurations, measurement tolerances, and analytical methodologies that the accredited laboratory is legally required to apply.
The Practical Pitfall for Manufacturers: If a manufacturer tests a product internally according to a modern IEC or EN edition, but the accredited laboratory is legally bound to an older intergovernmental GOST test method from List 2, the resulting test report cannot be accepted by the certification body. Selection of testing parameters must always be strictly matched against List 2.
Technical Standards Audit
A standards review must never merely verify the standard number without validating the exact edition and clause. Prior to commissioning a laboratory, our engineers verify that the testing facility is accredited precisely for the edition mandated in the TR CU List of Test Methods.
Customs Clearance for Test Samples: The Mandate of Decision No. 130
A critical compliance violation frequently committed by foreign exporters is dispatching test samples as "samples of no commercial value" via courier services or transporting them in personal passenger luggage. This invalidates the entire certification process.
Under the joint regulations of the EEC and the Federal Customs Service (including EEC Board Decision No. 130), the importation of samples for conformity testing is subject to a strictly regulated customs procedure:
- Customs Declaration under Procedure Code 061: Samples must be formally cleared through EAEU customs as "goods imported as samples for testing and certification". The customs declaration (DT) must identify the accredited certification body or the accredited laboratory as the consignee.
- Mandatory Supporting Documents:
- A contract between the foreign manufacturer (or its Authorized Representative) and the accredited certification body / testing laboratory;
- An official letter from the certification body specifying the required quantity and model selection of test samples;
- A commercial/proforma invoice explicitly stating: "Test samples for certification purposes under TR CU – Not for sale or commercial distribution".
Testing Methodologies: Non-Destructive, Destructive, and Witness Testing
Depending on the product's value, physical dimensions, and safety characteristics, the regulations distinguish several testing routes:
1. Non-Destructive Testing
Application: High-value capital goods, electronic controllers, measuring equipment, and industrial machinery.
Scope: Protective bonding resistance, dielectric withstand voltage, electromagnetic compatibility (EMC emission and immunity), functional performance, and pressure leak tightness.
Outcome: Samples remain undamaged and can be returned to the manufacturer or commercially utilized after testing concludes.
2. Destructive Testing
Application: Textiles, footwear, toys, polymers, raw materials, and hydraulic burst trials.
Scope: Tensile tear strength, flammability, drop impact from set elevations, container burst pressure limits, thermal degradation, and hazardous chemical extraction.
Outcome: The sample is consumed or irreversibly damaged during testing and is professionally disposed of by the laboratory.
3. Witness Testing
Application: Heavy machinery, industrial furnaces, large valve assemblies, and custom-built units that cannot be shipped.
Procedure: Testing takes place directly on the manufacturer's test field. An accredited expert from the EAEU certification body travels to the plant, validates the calibration of the test stands, and personally supervises the execution of the trials.
Establishing Representative Testing Groups (Worst-Case Principle)
When an enterprise manufactures extensive product lines featuring hundreds of model variations, testing each individual item is economically unfeasible. EAEU Decision No. 44/2018 (Section VI) authorizes grouping products into homogeneous product families.
Criteria for Establishing a Testing Family:
- Design Consistency: Identical operating principle, identical intended application, and equivalent mechanical/electrical layout.
- Identical Materials: Utilization of identical material grades, welding consumables, enclosure alloys, or electrical insulation systems.
- Common Manufacturing Facility: Production under uniform technological processes within the same manufacturing plant.
The Worst-Case Principle: The certification body selects the single model within the product family subjected to the highest operational stress (e.g., the motor with the highest power rating, the pressure vessel with the maximum design pressure, or the textile with the darkest pigmentation). If this sample passes laboratory testing, compliance is legally confirmed for all smaller or less stressed variants in the family. All covered models are explicitly listed in the official annex to the Certificate.
The Test Report: Mandatory Content, Deadlines, and Digital Registration
The outcomes of laboratory examinations are consolidated into a standardized test report (*Protokol ispytaniy*). It serves as the definitive basis for the certification body's legal determination:
Mandatory Content of the Test Report:
- Unique sequential registration number and official issuance date
- Full legal details and accreditation number of the testing laboratory
- Reference to the official Sampling Act (*Akt otbora prob*) and sample origin
- Precise identification of the samples (model, serial number, technical specifications)
- Applied testing standards with citations of mandatory GOST methods
- Actual measured numerical values shown alongside statutory tolerance thresholds
- Unambiguous concluding assessment on conformity with the Technical Regulation
Filing Deadlines and Statutory Archiving:
- 1-Year Window for Initial Filing: When applying for serial certificates or serial declarations (Schemes 1c, 3d, 6d), the test report must be no older than 1 year at the date of registration.
- Usage for Batch Deliveries (Scheme 4d): For batch shipments, test reports of identical earlier models may, under strict conditions (proven identity of formulation/design), be utilized for up to 2 years following issuance.
- Statutory 10-Year Archiving Obligation: Following registration, the Authorized Representative and the testing laboratory must retain the complete test report and technical file for at least 10 years for government inspection.

The Authorized Representative in the EAEU
Foreign manufacturers without an incorporated legal entity in the EAEU are prohibited from commissioning testing or filing registrations in their own name. Contracting an Authorized Representative incorporated within the Union's customs territory is mandatory under Union law.
The Authorized Representative executes the testing contract with the accredited laboratory, signs the Sampling Act, and acts as the official consignee for customs-compliant sample importation under procedure code 061.
If a local distributor or buyer is appointed as the applicant, all test reports become their exclusive property, leaving the foreign manufacturer commercially dependent. Schmidt & Schmidt acts as an independent Authorized Representative: We hold your test reports neutrally, ensure 10-year archiving, and guarantee that your test reports remain usable for an unlimited number of commercial partners.
Sanctions Compliance & Secure Laboratory Testing via Kazakhstan
Against the backdrop of European Union sanctions (Regulation (EU) No 833/2014) and Swiss SECO export controls, dispatching physical test specimens to Russia or Belarus creates severe corporate liability.
Primary Obstacles for Western Exporters:
- Dual-Use & Goods Embargoes: Numerous industrial machines, valves, electronic components, and advanced materials fall under export prohibitions (Annexes VII and XXIII); shipping functional samples to Russian testing bodies is subject to criminal penalties.
- Sanctioned Testing Facilities: Leading state-owned testing institutes in Russia and Belarus are designated on international sanctions lists (SDN / EU asset freeze lists); direct payments to these laboratories violate financial sanctions.
- Border Logistics Blockades: Suspended international courier services (DHL, FedEx, UPS) and comprehensive border inspections at EU frontiers regularly result in the impoundment of sample shipments.
The Secure Legal Solution via Schmidt & Schmidt in Kazakhstan:
As a founding EAEU member state, Kazakhstan operates a fully harmonized, internationally recognized state accreditation system:
- Testing is executed in state-of-the-art, accredited testing centers located in Almaty and Astana;
- Issued test reports and EAC certificates possess unrestricted legal validity across all five EAEU member states;
- Sample logistics from the EU, Switzerland, or the United States to Kazakhstan proceed fully compliant with export controls, free from customs seizure risks, using routine air cargo;
- Contracts and financial settlements are executed in Euros directly through our German headquarters in Passau.

Timeline, Costs, and Delivery of Test Documentation
Turnaround times and costs for laboratory testing of product samples depend on product classification, testing parameters, and logistics:
- Laboratory Testing Duration: Typically 1 to 2 weeks for standard trials (Low Voltage, EMC, standard mechanical parameters); approximately 3 to 5 weeks for complex testing scopes (explosion protection, endurance stress, toxicological assays).
- Total Project Duration (including logistics): Approximately 3 to 6 weeks (from customs-cleared sample delivery to final test report issuance).
- Cost Components: Accredited laboratory testing fees, drafting of the Sampling Act, customs clearance under procedure code 061, international freight/courier expenses, and technical translations of operating manuals.
