Dangerous goodsCorrect packaging is a prerequisite for safe and economic transport of goods.
You needs to know the folloing:
- the stresses that the goods must withstand
- the properties of the packaging materials
- the regulations and standards that apply
- the solutions that are possible
Characterisation of the transport environment
For various reasons, the stresses to which goods are subjected during transport are often considerably greater than expected. Vibration, temperature changes, moisture and chemicals can compound each other's effects and damage the goods, after which shocks and impacts can be the direct cause of damage. A description of the proposed transport environment is needed in order to decide on the appropriate packaging and method of packing. This can be based on known data, or on new measurements. Contact SP for further information.
Packaging materials have different characteristics and resistances to temperature, moisture, chemicals and mechanical loading. Durability and/or resistance to such effects as stress-raising cracking or chemicals, as well as performance, such as barrier properties or impact resistance, can be determined by testing.
Testing of packaging
Testing includes producing the same effects as those that are expected in service. Drop testing, pressure testing, vibration testing, stacking testing and lifting testing are therefore commonly used. It is important that materials and products under test are appropriately conditioned to allow for the effects of temperature, moisture or chemicals.
Dangerous goods are the subject of many regulations. Appropriate and proper application of these regulations, correct classification, suitable choice of packaging, approval compliance, dispensations etc. are problems that SP can assist in solving. We can also assist with risk analyses, investigations of damage and training.
By type-testing and certifying packaging, with approval for UN marking or P-marking, we provide formal proof that the tested materials or products are of the specified quality. Type-testing is always followed up by surveillance inspection, intended to ensure maintenance of the quality of the type-tested products. Our quality assessors are trained and certified in accordance with ISO 9000, QS 9000 and SQAS.
