EN 10204 – 3.2 Third Party Inspection Certificate for steel and metallic products. Third Party Inspection Certificate issued by PRVÁ ZVÁRAČSKÁ, a. s.
EN 10204 Certification is a European standard that defines the different types of inspection documents provided for metallic products such as steel plates, sheets/coils, pipes, bars. These inspection documents confirm that the materials supplied meet the specified technical requirements, chemical composition, and mechanical properties required for manufacturing and engineering applications.
Inspection documents according to EN 10204 are widely used in industries where material traceability and quality verification are critical. These industries include construction, pressure equipment manufacturing, oil and gas, power generation, railway manufacturing, and heavy engineering.
In many critical applications, inspection documents also require verification through a Third Party Certificate (Certification) to confirm that the material meets the required specifications and quality standards. This independent verification increases confidence in the reliability and traceability of materials used in industrial production.
PRVÁ ZVÁRAČSKÁ, a. s. performs verification and certification activities related to welding and manufacturing standards used in industrial fabrication and structural applications. Inspection documentation according to EN 10204 plays an important role in confirming the quality and compliance of materials used in these manufacturing processes.
What is EN 10204?
EN 10204 is a European standard that specifies the different types of inspection documents issued for metallic products. These documents are provided by the manufacturer to confirm that the supplied materials comply with the specified requirements, standards, and order specifications.
The inspection certificates include information such as material identification, test results, and verification that the product meets the required quality and technical criteria.
These documents verify that the material delivered complies with the order specifications, including chemical composition, mechanical properties, and inspection results.
The standard ensures transparency, traceability, and verification of material quality throughout the manufacturing and supply chain. In some applications, additional verification may be provided through a Third Party Certificate (Certification) issued by an independent inspection authority.
Types of EN 10204 Inspection Documents
The EN 10204 standard defines four main types of inspection documents that provide different levels of verification.
1. Type 2.1 – Declaration of Compliance with the Order
Type 2.1 is a basic declaration issued by the manufacturer stating that the supplied products meet the requirements of the purchase order.
Key characteristics:
- Issued by the manufacturer
- No specific test results included
- No independent verification
This document provides basic confirmation but does not include detailed inspection data.
2. Type 2.2 – Test Report
Type 2.2 includes a declaration of compliance along with test results based on non-specific inspections.
Key characteristics:
- Issued by the manufacturer
- Includes general test results
- Tests may not be performed on the exact supplied batch
This document provides more information compared to Type 2.1 but still does not include batch-specific verification.
3. Type 3.1 – Inspection Certificate
Type 3.1 is one of the most commonly used inspection documents in industrial applications.
Key characteristics:
- Issued by the manufacturer
- Includes specific test results from the supplied material batch
- Signed by the manufacturer’s authorized inspection representative independent of the production department
Type 3.1 provides verified material test results confirming that the supplied products meet the required specifications.
4. Type 3.2 – Inspection Certificate with Independent Verification
Type 3.2 is the highest level of inspection certification defined in EN 10204.
Key characteristics:
- Includes test results from the supplied batch
- Verified by both the manufacturer and an independent inspection authority or purchaser’s representative
- Often issued with a Third Party Certificate (Certification) confirming independent verification
This level is commonly required for critical applications where additional verification of material quality is necessary.
Importance of EN 10204 Certification
EN 10204 inspection documentation is widely used to ensure that metallic materials meet strict quality and performance requirements.
1. Material Traceability
Inspection documents provide traceability of materials from production to final application.
2. Quality Verification
Test results confirm the chemical composition and mechanical properties of the material.
3. Compliance with Engineering Standards
Many international engineering standards require EN 10204 inspection certificates or a Third Party Certificate (Certification) for material verification.
4. Safety Assurance
Proper inspection documentation reduces the risk of material failures in critical industrial applications.
5. Supply Chain Transparency
The standard ensures that material suppliers provide verified documentation confirming product quality.
Industries using EN 10204 Inspection Certificates
EN 10204 inspection documents are widely used across many industrial sectors.
