Safety, quality, and reliability

ISO Tank Container Certification

At Meeberg ISO Tanks & Containers, we ensure all our new & second hand tank containers are delivered with certifications from leading organizations such as Lloyd's Register (LR), American Bureau of Shipping (ABS), Bureau Veritas (BV) and SGS. This guarantees the highest standards of safety, quality, and reliability for your operations.


All our ISO Tank containers built to an approved pressure vessel code, typically ASME Section VIII, ensuring robust and reliable performance.

The ISO frame designs adhere to the standards of ISO 1496 Part 3, guaranteeing consistency and quality across our tank containers.

To meet global safety standards, our ISO dimension tank containers conform to the International Convention for Safe Containers (CSC).

Swap body frame designs are generally constructed in accordance with EN 1432, reflecting our commitment to European standards.

Additionally, our tanks comply with key international regulations, including IMDG, ADR, RID, and CFR 49, ensuring safety and reliability in all operating environments.

2.5-Year Test for ISO Tank Containers

The 2.5-year test, also known as the intermediate inspection, is a crucial part of maintaining ISO tank containers. Conducted halfway through the 5-year certification period, this test ensures that the tank remains in safe and operable condition.Key aspects of the 2.5-year test include:

  • Visual Inspection: A thorough visual check of the tank's exterior and interior surfaces to identify any signs of wear, corrosion, or damage.

  • Leak Test: Conducting a leak test to ensure the tank's integrity and that there are no leaks that could compromise safety.

  • Valve and Gasket Checks: Inspecting all valves and gaskets for functionality and integrity, replacing any that are worn or damaged.

  • Structural Integrity Assessment: Verifying that the frame and overall structure of the tank meet the required safety standards.

By performing this intermediate inspection, operators can detect and address potential issues early, ensuring the tank remains compliant with safety regulations and reducing the risk of unexpected failures.

5-Year Test for ISO Tank Containers

This test is more extensive than the intermediate 2.5-year test and involves a detailed assessment of the tank's condition and performance.Key aspects of the 5-year test include:

  • Internal and External Inspection: A thorough examination of both the interior and exterior surfaces of the tank to identify any corrosion, wear, or damage that could affect the tank’s integrity.

  • Hydrostatic Pressure Test: This test involves filling the tank with water and pressurizing it to check for leaks and ensure the tank can withstand its maximum working pressure without any issues.

  • Ultrasonic Thickness Testing: Measures wall thickness to ensure structural integrity.

  • Valve and Fitting Inspection: Checking all valves, fittings, and seals to ensure they are in good working condition.

  • Frame and Structural Assessment: Verifies compliance with ISO and CSC standards.

  • Documentation and Certification: Updating the tank’s certification to reflect that it has passed the 5-year test, ensuring it is compliant with relevant international standards such as IMDG, ADR, RID, and CFR 49.

The 5-year test is crucial for extending the operational life of the tank container, ensuring its safe use, and maintaining compliance with international safety and performance standards.

CSC Test for ISO Tank Containers

The CSC (International Convention for Safe Containers) test ensures ISO tank containers meet international safety standards for transport. Key aspects include:

  • Structural Integrity Inspection: Checking the frame and structural components for strength and stability.

  • Safety and Security Checks: Ensuring all locking mechanisms and securing devices are functional.

  • Identification and Marking Verification: Confirming the presence and legibility of the CSC plate and other required labels.

  • Dimensional Accuracy: Ensuring the container meets ISO dimensional standards.

  • Damage and Wear Assessment: Identifying any signs of damage or corrosion.

  • Maintenance Record Review: Checking that maintenance and previous inspections are documented.

The CSC test ensures containers are safe, compliant, and reliable for international transport.
