Hazardous Goods Package Testing

All hazardous good package testing is required to successfully complete testing before it is available for product transportation. Failure to comply with these regulations can result in serious injury to those handling the package and fines to the shipper of the product. Rigorous testing is essential to ensuring a package containing hazardous goods can withstand all typical road hazards experienced during transportation and guaranteeing safety when handling hazardous goods packages in transit. Utilizing the correct packaging during shipping depends on the given package’s hazard classification and its physical attributes. For example, shipping corrosive elements in metal packaging would chemically react and the hazardous goods would eventually break down the metal packaging used to contain it.

What is Hazardous Goods Package Testing?

Hazardous Goods Package Testing is necessary. 

Any packaged hazardous material requires compliance with regulatory standards to ensure containment of the material through the entire distribution cycle. Packaging safety requirements set forth by the Department of Transportation (DOT) and International Air Transport Association (IATA) govern the transportation of hazardous goods by ground and air. Shipments containing hazardous goods must be packaged in performance packaging consisting of inner and outer packaging designed, tested, and certified for the containment of hazardous materials. These packaging systems can then be identified by United Nations (UN) markings specifying the certification for containment of specific hazardous material classes and packing groups.

Dangerous substances and materials are initially placed in one of nine hazard classes, better known as UN Classes according to their main hazard type (listed below). An assessment is then made of the relative hazard of a substance or material within the same class. Each substance is given an identification number to ensure identification during transit is possible. These identification numbers are commonly known as UN numbers. The UN suggests that all UN numbers be displayed on all transit documents and included on packages, shipping containers, and vehicles along with an official description of the material or substance.

UN Packaging Codes / Hazardous Goods Package Testing

The storage and transportation of hazardous materials (HAZMAT) is overseen and regulated by federal and international law. A comprehensive marking system called the UN marking guide was developed so that HAZMAT packaging can describe what type and how much of a material may be transported within a package. A UN code is a universal system of demarcation developed by the United Nations and used internationally for the classification, packaging, marking, and labeling of dangerous goods to better transport them safely. Rigorous testing is required before a UN certification mark can be given.
