What is EN 10204 Certificate?


In industrial manufacturing processes, it is crucial to document the quality and conformity of products. Customers want to ensure that the products provided by suppliers meet specifications and fulfill their requirements. The EN 10204 certificate serves this purpose by providing comprehensive information about the properties and characteristics of a product, along with its test results and compliance with relevant standards. This article aims to provide a detailed overview of the EN 10204 certificate, covering its general information, applications, types, technical details, dimensions and tolerances, chemical properties, mechanical properties, and certification process.

General Information about the EN 10204 Certificate

The EN 10204 certificate, also known as the “inspection certificate,” is an internationally recognized document that verifies the quality and characteristics of a product. It serves as evidence that the product has undergone rigorous testing and inspection, and it provides a transparent and traceable record of its properties. The certificate contains essential details such as the product’s description, test results, and the signatures of authorized personnel.

Applications of the EN 10204 Certificate

The EN 10204 certificate is widely used across various industries, including manufacturing, engineering, construction, and oil and gas. It is particularly crucial in sectors where safety, reliability, and compliance with specifications are of utmost importance. This certificate is often required in projects involving complex components, machinery, and critical infrastructure. It provides confidence to customers and end-users that the supplied products meet the required standards and specifications.

Types of EN 10204 Certificates

There are several types of EN 10204 certificates, each denoted by a specific code. The most common types include:

  1. Type 2.1: This type of certificate states that the products are supplied in accordance with the order requirements but does not include any test results.
  2. Type 2.2: It confirms that the products are manufactured in compliance with the order requirements and provides test results from non-specific inspections.
  3. Type 3.1: This certificate indicates that the products are manufactured as per the order requirements and includes specific test results from an independent testing agency.
  4. Type 3.2: It is the most stringent certificate, providing assurance that the products have been tested and inspected by an independent agency, and the results have been verified by a third-party authority.

Technical Details, Dimensions, and Tolerances

The EN 10204 certificate includes comprehensive technical information about the product. This encompasses details such as dimensions, tolerances, materials used, and manufacturing processes employed. It ensures that the product conforms to the specified requirements and helps users determine its suitability for their intended applications. The certificate provides clear guidelines on the product’s size, shape, and permissible variations, enabling customers to make informed decisions based on their specific needs.

Chemical Properties

The chemical properties section of the EN 10204 certificate provides detailed information about the composition of the product. It includes the percentages of various elements present in the material, such as carbon, sulfur, phosphorus, and alloying elements. This data is vital for assessing the product’s corrosion resistance, heat resistance, and suitability for specific environments or applications. By understanding the chemical properties, users can ensure compatibility with their intended use and make informed decisions regarding material selection.

Mechanical Properties

The mechanical properties section of the EN 10204 certificate provides crucial information about the product’s strength, hardness, ductility, and other mechanical characteristics. It includes parameters such as tensile strength, yield strength, elongation, impact resistance, and hardness values. These properties play a vital role in determining the product’s structural integrity, durability, and performance under different conditions. By examining the mechanical properties, users can assess the product’s suitability for their specific mechanical and structural requirements.

Certification Process

To obtain an EN 10204 certificate, the product undergoes a series of tests and inspections by qualified personnel or independent testing agencies. The certification process ensures that the product complies with the specified standards and meets the required specifications. The certificate is issued by an authorized body, and it includes the necessary information, test results, and the signatures of responsible parties. The certificate serves as proof of conformity and provides assurance to customers and end-users about the quality and reliability of the product.


The EN 10204 certificate is a crucial document that provides comprehensive information about the properties, characteristics, and compliance of a product with specified standards. It plays a vital role in ensuring product quality, reliability, and conformity to requirements. By understanding the general information, applications, types, technical details, dimensions and tolerances, chemical properties, mechanical properties, and the certification process associated with the EN 10204 certificate, customers and end-users can make informed decisions and have confidence in the products they acquire.
