Material Specification Checks
Ensures consistency in packaging quality and compliance.
To verify compliance and ensure repeatability, each packaging system undergoes material and design verification. These assessments confirm that every future production run matches the approved sample exactly.
Key Requirements
Typical inspection for boxes includes and records the specifications of:
- Wall thickness and material grade
- Fluting
- Grammage
- Dimensions and tolerances
- Closure systems (caps, seals, tape, fasteners)
- Moulding consistency and performance attributes
This ensures all future production runs replicate the packaging that passed the original UN testing. 
In the case of steel and fibre drums, drum and closures are all inspected, and their specifications are recorded to ensure that each production run uses the exact same materials and specifications to create the UN approved packaging. This is to ensure the final packaging product is made to the exact specification which passed the UN Testing process resulting in UN approved packaging.
Typical specification checks include material composition, lacquered or plain, material thickness, material weight, dimensions, closures spec/seals, weld specification and capacity.
UN performance testing is a critical step in ensuring your dangerous goods are transported safely and in line with UN DG transport regulations. At Air Sea Containers, we simplify the process and provide you with expert support every step of the way.
