Hazard class 9 Pyrophoric Liquids 10 Pyrophoric Solids 11 Self-heating Substances and Mixtures 12 Substances and mixtures which,in contact with water,emit flammable gases Classification result Not classified Not classified Not classified Not classified Not classified Not classified Not classified Not classified 13 Oxidizing Liquids Not classified 14 Oxidizing Solids Not classified 15 Organic Peroxides Not classified 16 Corrosive to Metals Not classified ○ Supplement concerning Judgment of "not classified" ■Explosives 【GHS 2 nd revised edition】(2.1.4.2.2) A substance or mixture is not classified as explosive if: 24 Grounds and Example Entries Non-combustibility (Title of the review document, year) Does not self-ignite upon contact with water of ambient temperature.(Title of the review document, year) TDG classification is class 3. (UN number) Non-combustibility (Title of the review document, year) Do not self-ignite when contacts with water of ambient temperature. (Title of the review document, year) Non-combustibility (Title of the review document, year) Stable against water(Title of the review document, year) Stable against water (based on experience, name of the evaluating organization) Reductive material (Title of the review document, year) Reductive material (Title of the review document, year) Active oxygen amount is less than in the definition. Copper and aluminum may be used as container. (Title of the review document, year) (a) There are no chemical groups associated with explosive properties present in the molecule. Examples of groups which may indicate explosive properties are given in Table A 6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria; or (b) The substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than -200. The oxygen balance is calculated for the chemical reaction: CxHyOz + [x + (y/4)-(z/2)] O2 x. CO2 + (y/2) H2O using the formula:
oxygen balance = -1600 [2x +(y/2) -z]/molecular weight; (c) When the organic substance or a homogenous mixture of organic substances contain chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition to prevent the procedure being applied to a large number of organic materials which are not explosive but which will decompose energy may be determined using a suitable calorimetric technique; or (d) For mixtures of inorganic oxidizing substances with organic material(s), the concentration of the inorganic oxidizing substance is: less than 15 % , by mass, if the oxidizing substance is assigned to Category 1 or 2; less than 30 % , by mass, if the oxidizing substance is assigned to Category 3. ■Self-reactive Substances and Mixtures 【GHS 2 nd revised edition】(2.8.4.2) The classification procedures for self-reactive substances and mixtures need not be applied if: (a) There are no chemical groups present in the molecule associated with explosive or selfreactive properties; examples of such groups are given in Tables A6.1 and A 6.2 in the A ppendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria; or (b) For a single organic substance or a homogeneous mixture of organic substances, the e exothermic decomposition energy is less than 300 J/g. The onset temperature and decomposition energy may be estimated using a suitable calorimetric technique (see 20.3.3.3 in Part II of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria). ■Flammable Liquids or Solids, Pyrophoric Liquids or Solids, Self-heating Substances and Mixtures In the cases where the subsitance is confirmed to be noncombustible based on the information of the prescribed review document, enter “Not classified” for “Classification result” and “Non-combustibility” for “Classification Grounds and problems,” with regard to “Flammable Liquids or Solids”, “Pyrophoric Liquids or Solids”, and “Self-heating Substances and Mixtures”, . Note:Flame-resistant substances are “not classified” either for those hazard classes, but the boundary between combustibility and flame-resistance is not clearly defined. Accordingly, in this classification, only if a substance is confirmed to be noncombustible based on the prescribed review document, enter "not classified" for “Classification result”. 25
