The Manual of Tests and Criteria contains criteria test methods and procedures to be used for the classification of dangerous goods according to the provisions of the “United Nations Recommendations on the Transport of Dangerous Goods Model Regulations” as well as of chemicals presenting physical hazards according to the “Globally Harmonized System of Classification and Labelling of Chemicals (GHS)”. It therefore also supplements national or international regulations which are derived from the Model Regulations or the GHS. Originally developed by the Economic and Social Council’s Committee of Experts on the Transport of Dangerous Goods which adopted a first version in 1984 the Manual of Tests and Criteria has been regularly updated and amended. Currently the updating is done under the auspices of the Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals which replaced the original committee in 2001.

The Manual of Tests and Criteria contains criteria test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods Model Regulations as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). As a consequence it supplements also national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS. At its ninth session (7 December 2018) the Committee adopted a set of amendments to the sixth revised edition of the Manual as amended by Amendment 1. This seventh revised edition takes account of these amendments. In addition noting that the work to facilitate the use of the Manual in the context of the GHS had been completed the Committee considered that the reference to the “Recommendations on the Transport of Dangerous Goods” in the title of the Manual was no longer appropriate and decided that from now on the Manual should be entitled “Manual of Tests and Criteria".

Originally developed by the Economic and Social Council’s Committee of Experts on the Transport of Dangerous Goods which adopted a first version in 1984 it has been regularly updated and amended every two years. The amendments listed in this publication include: amendments to the procedure for assignment to a Division of Class 1; amendments to test series 7 for the classification as extremely insensitive explosive article; a test method for the classification of gases and gas mixtures as chemically unstable (new section 35); amendments to the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries; amendments to the variations permitted for MEGCs design without additional testing; and a new appendix 8 detailing the response descriptors to be used for the purposes of Test series 7.

This document is adopted from the Recommendation on the Transport of Dangerous Goods: Manual of Tests and Criteria publication. It is the first amendment of the third revised edition concerning new provisions for the classification criteria and testing procedures for lithium batteries.
