Rack Low Temperature Resistance CE Certification

Industrial racks with low-temperature resistance can achieve CE certification by complying with EU structural and safety standards, including EN 1090-1 for steel structures and EN ISO 3834 for welding quality, alongside relevant product-specific directives.

CE Marking Overview

CE marking is a declaration by the manufacturer that a product meets all applicable EU requirements, allowing it to be sold freely within the European Economic Area (EEA) . For industrial racks, CE marking primarily involves compliance with structural safety, material quality, and manufacturing standards. The manufacturer is responsible for ensuring that all components, including those affected by low temperatures, meet these requirements .

Applicable Standards for Industrial Racks

1. EN 1090-1: This standard is mandatory for steel structures permanently incorporated into buildings, including metal-clad rack warehouses. It ensures that the structural integrity of racks is verified through controlled manufacturing processes, welding inspections, and material testing . Compliance with EN 1090-1 allows the manufacturer to affix the CE mark to the rack.
2. EN ISO 3834: This standard ensures that welding processes meet quality requirements. It is divided into three levels—full, normal, and basic quality requirements—depending on the complexity and criticality of the welded components . Proper welding is essential for racks to maintain strength under low-temperature conditions.
3. Material and Coating Requirements: Low-temperature resistance may require specific steel grades and coatings that maintain mechanical properties at sub-zero temperatures. While not explicitly covered by CE marking directives, these requirements are part of the technical documentation supporting the CE declaration .

Low-Temperature Considerations

Racks intended for cold storage or outdoor use in freezing conditions must be tested for:

• Brittle fracture resistance: Ensuring steel does not crack under low temperatures.
• Load-bearing capacity: Verifying that the rack can support rated loads without deformation.
• Welding integrity: Confirming that welds remain strong and do not fail in cold environments. These tests are typically documented in the technical file required for CE marking and may involve third-party testing if the product falls under higher-risk categories .

Conformity Assessment and Documentation

To legally affix the CE mark:

1. Conduct a risk assessment and ensure compliance with EN 1090-1, EN ISO 3834, and any other relevant EU directives.
2. Prepare a technical file documenting design, materials, welding procedures, and low-temperature performance.
3. Issue an EU Declaration of Conformity (DoC) stating that the rack meets all applicable requirements .
4. If required, involve a Notified Body for third-party verification, especially for structural or safety-critical racks .

Summary

CE certification for low-temperature resistant racks involves structural compliance (EN 1090-1), welding quality (EN ISO 3834), and documented performance under cold conditions. Manufacturers must maintain a technical file, perform necessary testing, and issue a Declaration of Conformity to legally place the racks on the EU market. Third-party testing may be required for higher-risk applications or when mandated by specific directives .
