DANGEROUS GOODS TESTING
NATS is able to perform all the requirements for testing
packaging materials for UN Specification packaging (non-bulk). This
extensive testing protocol is accompanied by a detailed report with digital
photographs. Changes to the Transportation of Dangerous Goods (TDG)
regulations announced this year stipulate that all dangerous goods must be
packaged in United Nations' Performance Packaging, or the goods cannot move.
Enforcement of these UN regulations is becoming increasingly more
rigorous. We assist customers to comply with the regulatory requirements
of various government agencies, including Transport Canada, and prepare
submissions for presentation to these agencies.
Drop Tests (Ambient & Cold)
A critical component of both the ISTA and Dangerous Goods protocols, the drop
tester (cap. 150 pounds) reproduces hazards in the field, and pinpoints design
deficiencies. Most types of packages should be tested for leakage after
conducting the applicable drop test. The drop height is dependent on the
material being packaged.
Stacking
Both small boxboard containers and full size pallet loads are compression tested
on our full-size machine. Given the pallet loading pattern and gross weight,
stacking estimates on pallet loads can be made. Almost all packaging must be
tested under load. The load is calculated based on a formula which incorporates
the mass and height of the filled package.
Cobb Water Absorption
The performance of functional coatings and the water resistance of packaging
materials can be predicted through the Cobb test. The outside facing of
fibreboard must only absorb absorb a maximum of 150 gm of water per square metre
of liner. Our lab routinely performs this test.
Internal Pressure & Leakproofness
Certain package types require the testing for the ability to withstand increased
internal pressure, particularly for air shipment. NATS is able to perform such
testing. |
