Container House CE Standard

The CE standard for container houses is mainly implemented in accordance with the EN1090 standard, which is a steel structure certification requirement under the EU Construction Products Regulation (CPR) (Regulation (EU) No 305/2011).

I. Core Content of the EN1090 Standard

The EN1090 standard is divided into three parts:

• EN 1090-1: Basic requirements for the conformity assessment of structural components, clarifying processes such as factory production control and initial type testing.
• EN 1090-2: Technical requirements for steel structures, specifying performance indicators such as material, welding, wind and earthquake resistance.
• EN 1090-3: Technical requirements for aluminum structures (usually not applicable to container houses).

This standard falls under the System2+ certification category and requires passing through processes such as the factory production control system (FPC), welding personnel qualifications, material certificate verification, and product performance parameter testing.

II. Key Points of CE Certification

1. Execution Level Selection: Choose an execution level from EXC1 to EXC4 according to the intended use of the container house (EXC1 is the minimum requirement, and EXC4 is the highest).
2. Materials and Welding: Material certificates (such as EN10025 standard steel) must be provided, and the welding system must comply with the requirements of EN 1090-1 Table B.1.
3. Performance Testing: Includes indicators such as fire resistance, water resistance, wind resistance (usually required to reach levels 10-12), and thermal insulation. For example, the filling material must use Class A fire-resistant rock wool boards.
4. Marking and Documentation: The product must be affixed with the CE mark, and a Declaration of Conformity (DoP) must be signed, providing a VoC (Verification of Conformity) certificate and third-party test reports.

III. Certification Process and Challenges

1. Documentation Preparation: House drawings, exploded views, material lists, and test reports recognized by the importing country (such as LVD/EMC certification for electrical appliances) must be submitted.
2. Cost and Cycle: The certification cost is relatively high, and the cycle is uncertain, depending on the complexity of the product and the test results of the samples.
3. Compliance Risks: If the materials or welding do not meet the standards, it may lead to certification failure or a ban from the EU market. For example, the use of flammable materials such as polystyrene directly violates fire safety requirements.

IV. Compliance Cases in Practical Applications

Some companies (such as Suzhou Shengshan Integration) have passed the EN1090 certification. Their products have a wind resistance level of 10-12, an applicable temperature range of -10℃ to 50℃, a design life of over 15 years, and hold VoC certificates and third-party test reports, meeting the EU market access requirements.
