United Nations Manual of Tests and Criteria - 7th Edition

The Manual of Tests and Criteria provides the essential framework for the classification of dangerous goods. Published by the United Nations, this Seventh Revised Edition serves as a vital technical resource for professionals working with the transport of hazardous materials. It contains the specific criteria, test methods, and procedures required to classify dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations. Beyond transport regulations, this manual is a key resource for identifying chemicals that present physical hazards under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Because many national and international regulations are derived from these United Nations Recommendations, this manual functions as a foundational text for maintaining safety and compliance in global logistics and chemical management. It is a necessary reference for ensuring that substances are correctly categorized and handled according to international standards.
