Flammable gas means a gas or gas mixture having a flammable range with air at 20oC and a standard pressure of 101,3kPa. Possible test methods for determining the flash point of flammable liquids are listed inTable 2.6.3. Data can be determined by testing, found in literature or calculated. Spontaneous combustion occurs when the rate of heat production exceeds the rate of heat loss and the auto-ignition temperature is reached. Thermal stability: according to UN Test3(c) (sub-section13.6.1 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria). Pyrophoric solid means a solid substance or mixture which, even in small quantities, is liable to ignite within five minutes after coming into contact with air. 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. The assessment whether a candidate for ammonium nitrate emulsion or suspension or gel, intermediate for blasting explosives (ANE) is insensitive enough for inclusion as an oxidising liquid (section2.13) or an oxidising solid (section2.14) is answered by Test Series 8 tests. The exothermic decomposition energy can be determined using a suitable calorimetric technique; or. xmlns:atom="http://www.w3.org/2005/Atom" @import "/styles/legislation.css";@import "/styles/eulegislation.css"; explosive articles, except devices containing explosive substances or mixtures in such quantity or of such a character that their inadvertent or accidental ignition or initiation shall not cause any effect external to the device either by projection, fire, smoke, heat or loud noise; and. This is also possible for small series of max. Readily combustible solids are powdered, granular, or pasty substances or mixtures which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly. Label elements for substances and mixtures corrosive to metals, for the purposes of testing steel, steel types. There are no chemical groups associated with explosive properties present in the molecule. A positive result is obtained in a test using a 25mm sample cube at 140, H252: Self-heating in large quantities; may catch fire. Without a confirmation of this UN 38.3 test lithium cells and lithium batteries may only be transported following stricter requirements as so called prototypes. The test shall be performed on the substance or mixture in its physical form as presented. The classification procedure is set out in the following decision logic (see Figures2.1.1 to2.1.4). For a single organic substance or a homogeneous mixture of organic substances, the estimated SADT for a 50kg package is greater than 75oC or the exothermic decomposition energy is less than 300J/g. If, for example, for the purposes of supply or transport, the same chemical is to be presented in a physical form different from that which was tested and which is considered likely to materially alter its performance in a classification test, the substance shall also be tested in the new form. Oxidising solid means a solid substance or mixture which, while in itself is not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material. As determined by test series E as prescribed in UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, PartII.

The classification of a self reactive substance or mixture shall be performed in accordance with test series A to H as described in PartII of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria. We have developed checklists for this transport variety also, even though the appropriate national authority of the state of departure and the appropriate national authority of the licensing state of the operator will determine the requirements for transport and especially for packaging for each individual case. Most pure gases are already classified in the UN Recommendations on the Transport of Dangerous Goods, Model Regulations. H271: May cause fire or explosion; strong oxidiser, Corrosion rate on either steel or aluminium surfaces exceeding 6,25mm per year at a test temperature of 55. Any substance or mixture which, in the 4:1 or 1:1sample-to-cellulose ratio (by mass) tested, exhibits a mean burning time less than the mean burning time of a 3:2mixture, by mass, of potassium bromate and cellulose. Here a very important tip from experience: Batteries are subject to the UN 38.3 test regardless of whether the cells they are composed of have passed the test or not. For mixtures of inorganic oxidising substances with organic material(s), the concentration of the inorganic oxidising substance is: less than 15% by mass, if the oxidising substance is assigned to Categories1 or2; less than 30% by mass, if the oxidising substance is assigned to Category3. : A flammable aerosol shall be classified in one of the two categories for this Class on the basis of its components, of its chemical heat of combustion and, if applicable, of the results of the foam test (for foam aerosols) and of the ignition distance test and enclosed space test (for spray aerosols) in accordance with Figure 2.3.1 and the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, PartIII, sub-sections31.4, 31.5 and 31.6. You have to look very closely what the manufacturer or supplier confirms. For flash point determination a closed-cup method shall be used. Any self-reactive substance or mixture shall be considered for classification in this class as a self-reactive substance or mixture unless: Mixtures of oxidising substances, meeting the criteria for classification as oxidising substances, which contain 5% or more of combustible organic substances and which do not meet the criteria mentioned in (a), (c), (d) or (e) in 2.8.2.1, shall be subjected to the self-reactive substances classification procedure; Self-reactive substances and mixtures shall be classified in one of the seven categories of types A to G for this class, according to the following principles: The properties of self-reactive substances or mixtures which are decisive for their classification shall be determined experimentally. Liquids with a flash point of more than 35. Powders of metals or metal alloys shall be classified as flammable solids when they can be ignited and the reaction spreads over the whole length of the sample in 10minutes or less. The onset temperature and decomposition energy can be estimated using a suitable calorimetric technique (see PartII, sub-section20.3.3.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria). substances, mixtures and articles not mentioned in points (a) and (b) which are manufactured with a view to producing a practical, explosive or pyrotechnic effect. Note: The sum of the individual parts can be more hazardous than the individual components. For a composite aerosol formulation, the chemical heat of combustion is the summation of the weighted heats of combustion for the individual components, as follows: mass fraction of component i in the product; specific heat of combustion (kJ/g)of component i in the product. The details on the Quality Management Programm on the manufacture of lithium cells / lithium batteries weve provided for you under this link:https://www.lithium-batterie-service.de/en/quality-management-program. Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state. January 2019 in the UN manual of tests and criteria a new subsection 38.3.5 was included which refers to the specific regulations of the different transport modes.Since 01. Gases which cause or contribute to the combustion of other material more than air means pure gases or gas mixtures with an oxidising power greater than 23,5% as determined by a method specified in ISO 10156 as amended or 10156-2 as amended. H270: May cause or intensify fire; oxidiser, A gas which when packaged under pressure is entirely gaseous at -50. Any substance or mixture which reacts slowly with water at ambient temperatures such that the maximum rate of evolution of flammable gas is equal to or greater than 1 litre per kilogram of substance per hour, and which does not meet the criteria for Categories1 and 2. Examples of groups which may indicate explosive properties are given in Table A6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria; or. You may download these combined UN38.3 Test Summary and Supplier Inquiry Forms under these links: This combined UN 38.3 Test Summary and Supplier Inquiry Forms we provide to you free of charge. A pyrotechnic article is an article containing one or more pyrotechnic substances or mixtures. For detailed schemes for the decision logic for classification and the tests to be carried out for ascertaining the different categories, see Figure2.11.1. Powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys see2.7.2.2) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in PartIII, sub-section33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2,2mm/s. the SADT is 60oC or higher for a 50kg package(4), and, for liquid mixtures, a diluent having a boiling point of not less than 150oC is used for desensitisation, shall be defined as organic peroxide TYPE G. If the organic peroxide is not thermally stable or a diluent having a boiling point less than 150oC is used for desensitisation, the organic peroxide shall be defined as organic peroxide TYPEF. The following organic peroxides need to be subjected to temperature control: Organic peroxide typesB and C with an SADT 50C; Organic peroxide typeD showing a medium effect when heated under confinement(5) with an SADT 50oC or showing a low or no effect when heated under confinement with an SADT 45oC; and. These tests simulate transport conditions like pressure, temperature, crush, impact ect. This comprises substances, mixtures and articles which are manufactured with a view to producing a practical, explosive or pyrotechnic effect. their self-accelerating decomposition temperature (SADT) is greater than 75oC for a 50kg package(3). Label elements shall be used for substances or mixtures meeting the criteria for classification in this hazard class in accordance with Table2.3.2.

Liquids with a flash point 93oC, which includes Flammable Liquids according to section2.6; Flammable components do not cover pyrophoric, self-heating or water-reactive substances and mixtures because such components are never used as aerosol contents. The properties of organic peroxides which are necessary for their classification shall be determined experimentally. January 2019 two tables have been added which present a nice overview on the number of test samples for each of the tests in the UN test series 38.3: Requirement of a UN 38.3 Test Summary from 01.

Of course this is also needed for lithium cells and/or lithium batteries that are already installed in equipment. In cases where substances or mixtures generate a pressure rise (too high or too low), caused by chemical reactions not characterising the oxidising properties of the substance or mixture, the test described in PartIII, sub-section34.4.2 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria shall be repeated with an inert substance, e.g. For the classification of aerosols, see 2.3. the substance is known to be stable at room temperature for prolonged periods of time (days)). Any substance or mixture which, in the 1:1mixture, by mass, of substance (or mixture) and cellulose tested, exhibits a mean pressure rise time less than or equal to the mean pressure rise time of a 1:1mixture, by mass, of 65% aqueous nitric acid and cellulose; and the criteria for Category1 and 2 are not met. The test methods are described in PartI of the UNRecommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria. Any substance or mixture which, in the 4:1 or 1:1sample-to-cellulose ratio (by mass) tested, exhibits a mean burning time equal to or less than the mean burning time of a 3:7mixture (by mass) of potassium bromate and cellulose and the criteria for Categories1 and 2 are not met. The classification procedures for self-reactive substances and mixtures need not be applied if: A pyrophoric liquid shall be classified in a single category for this class using test N.3 in PartIII, sub-section33.3.1.5 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria according to Table 2.9.1: The classification procedure for pyrophoric liquids need not be applied when experience in manufacture or handling shows that the substance or mixture does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. For this an exemption from the appropriate national authority is needed every time. The test shall be performed on the substance or mixture in its physical form as presented. Any substance or mixture which reacts vigorously with water at ambient temperatures and demonstrates generally a tendency for the gas produced to ignite spontaneously, or which reacts readily with water at ambient temperatures such that the rate of evolution of flammable gas is equal to or greater than 10litres per kilogram of substance over any one minute. A certification according to ISO 9001 of the manufacturing process would fulfill all requirements of the transport regulations on the Quality Management Program for the manfuacture of the lithium cells / lithium batteries. In most of the checklists you can find a checkpoint regarding the so called UN 38.3 Test. Mixtures of already classified organic peroxides may be classified as the same type of organic peroxide as that of the most dangerous component. The critical temperature is the temperature above which a pure gas cannot be liquefied, regardless of the degree of compression. Neither a Series1 type(a) propagation of detonation test nor a Series2 type(a) test of sensitivity to detonative shock is required if the exothermic decomposition energy of organic materials is less than 800J/g.
