Testing Procedures for UN Bulk Bags

Our UN Certified bags include a 6:1 Safety Factor and meets stringent DOT standards. Testing procedures as follows:

Drop Test: FIBC/bulk bag is lifted and dropped at a specified height. Drop heights are determined by packaging group, with standards at: I at 5.9 feet; II at 3.9 feet; and III at 2.6 feet. Some larger bags, or those carrying heavier materials, will have slightly smaller drop heights.

Stacking Test: FIBC/bulk bag is stacked on a number of bags. Each bag will need to be at least 95% full and then will be placed on a solid, flat surface. They will be tested with a uniformly distributed load for at least five minutes. If you’re using the FIBC in conjunction with composite materials, crates or other equipment, it may need to be tested in conjunction with the bulk bags. Packaging will be tested using a dynamic compression testing machine or similar apparatus to ensure that the entire FBIC is functioning properly.

Top Lift Test: FIBC/bulk bag is tested at 6x the SWL. The load must be evenly distributed and the lift test will clear the floor and maintain the lift position for at least five minutes. Flexible IBCs will need to be 95% full with a material that is representative of the product being shipped.

Topple Test: FIBC/bulk bag is toppled at a specified height. Heights vary from 5.9 feet to 2.6 feet, based on the Packaging Group, and the bag will need to be toppled onto any part of its top onto a smooth, non-resilient surface. To pass the test, the bag will need to be 95% full and have no loss of contents from the topple. Slight discharge from stitch holes and other intended areas is not an immediate failure, as long as leakage doesn’t continue.

Righting Test: The toppled FIBC/bulk bag is lifted by only two corner lifting loops. Lifting occurs from the top or the side on a bag that’s at least 95% full. The lift speed will be 0.33 feet per second from its side to an upright position, clear of the floor, by one or two lifting devices. Bags pass this test when there is no damage to the FIBC or the lifting device itself.

Tear Test: Specified cut is applied to middle of FIBC / bulk bag and must hold 2x the SWL. In this test, the bag will be completely penetrated with a cut made at a 45° angle to the principal axis, halfway between the bottom surface and the top level of the contents. Passing this test requires a sturdy bag that prevents the cut from propagating more than 25% of the original cut length.

Title 49 Code of Federal Regulations

Transportation is one of the main focuses in the U.S. Code of Federal Regulations and it is governed principally in Title 49, as this is issued by the Department of Transportation, Department of Homeland Security and other federal agencies governing hazardous material handling and movement. There are multiple specifications that cover flexible bulk UN containers.

Beyond standard packaging requirements, §173.24b presents a variety of additional general requirements for bulk packaging. These include:

  • Liquids and liquefied gases must be so loaded that the outage is at least 5% for materials deemed poisonous by inhalation, or at least 1% for all other materials, measured by the total capacity of the container, such as the cargo tank. Tank cars and similar compartment units are allowed to include their dome capacity.
  • Hazardous materials cannot be directly loaded into the dome of a tank car, and additional vacant space will be required if the dome of the tank car does not provide sufficient outage.

When using bulk packaging in tank cars, specific temperature caps must be adhered to, based on what is being transported and in what situation:

  • 46° C (115° F) for a non-insulated tank.
  • 41° C (105° F) for an insulated tank.
  • 43° C (110° F) for a tank car that has a thermal protection system. The system needs to incorporate a metal jacket that provides an overall thermal conductance at 15.5° C (60° F) of no more than 10.22 kilojoules per hour per square meter per degree Celsius.

A few other key regulations for you to consider include:

  • §178.1020: The use of flexible bulk containers for the transport of hazardous materials is permitted for a period of time not to exceed two years from the date of manufacture of the flexible bulk containers.
  • §178.1015 (a): Each flexible bulk container must be sift-proof and completely closed during transport to prevent the release of contents, and waterproof.
  • §178.1015 (b:1-2): Flexible bulk containers used with hazardous materials must not be affected or weakened by those materials. The bags cannot cause new dangers, such as creating a catalyzing reaction with the hazardous materials.
  • §178.1015 (b:3): UN bags cannot be permeable — so hazardous materials cannot leak or otherwise vacate to cause a new hazard. Filling and discharge devices must be properly secured during handling and shipping. Ventilation devices must be fitted to any bulk containers if the hazardous material could cause an unsafe buildup of gases.

UN Recommendations on the Transport of Dangerous Goods

The UN Model Regulations also provide guidance on how to use bulk packaging for the shipment of dangerous or hazardous goods. Many of these guidelines will follow the same mode of thought as the Title 49 requirements, such as not combining shipments of hazardous materials that may react, whether in the bag or with the bag itself.

It makes many notations that your shipping partners, and those throughout your supply chain, will appreciate. This includes Section, which notes that liquids shall be filled only into packaging, including these FIBCs, that have an appropriate resistance to the internal pressure that is likely to occur during normal transportation conditions.

One of the most important sections for our customers is when IBCs are used for the transport of liquids with a flash point of 60° C or lower, or of powders liable to dust explosion, measures shall be taken to prevent dangerous electrostatic discharge. Measures can include selecting the appropriate type of container as long as it has passed the relevant testing before being put into service.

These are just a small set of the relevant codes, regulations and statues that your equipment must adhere to if you’re shipping hazardous or other reactive materials. No website can do proper justice to preparing your team or ensuring that everything is being appropriately handled.

We recommend that you reach out right away to learn more about what requirements you’ll need to adhere to, based on your materials, shipping methods and lanes, volumes and more.
