‘2.2.4.1.
Flammability shall be determined by tests or, for mixtures where there are sufficient data available, by calculation in accordance with the methods adopted by ISO (see ISO 10156 as amended, “Gases and gas mixtures — Determination of fire potential and oxidising ability for the selection of cylinder valve outlets” and, if using fundamental burning velocity for Category 1B, see ISO 817 as amended “Refrigerants-Designation and safety classification, Annex C:- Method of test for burning velocity measurement of flammable gases”). Instead of the test apparatus according to ISO 10156 as amended, the test apparatus for the tube method according to clause 4.2 of EN 1839 as amended (Determination of explosion limits of gases and vapours) may be used.’
The following sections 2.2.4.2 and 2.2.4.3 are inserted:
‘2.2.4.2.
Pyrophoricity shall be determined at 54 °C in accordance with either IEC 60079-20-1 ed1.0 (2010-01) “Explosive atmospheres – Part 20-1: Material characteristics for gas and vapour classification – Test methods and data” or DIN 51794 “Determining the ignition temperature of petroleum products”.
2.2.4.3.
The classification procedure for pyrophoric gases need not be applied when experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at a temperature of 54 °C or below. Flammable gas mixtures, which have not been tested for pyrophoricity and contain more than one percent pyrophoric components, shall be classified as a pyrophoric gas. Expert judgement on the properties and physical hazards of pyrophoric gases and their mixtures shall be used in assessing the need for classification of flammable gas mixtures containing one percent or less pyrophoric components. In this case, testing need only be considered if expert judgement indicates a need for additional data to support the classification process.’

(r)
The following section 2.17 is added:
‘2.17. Desensitised explosives
2.17.1. Definitions and general considerations
2.17.1.1. Desensitised explosives are solid or liquid explosive substances or mixtures which are phlegmatised to suppress their explosive properties in such a manner that they do not mass explode and do not burn too rapidly and therefore may be exempted from the hazard class “Explosives” (see also paragraph 3 in section 2.1.4.1) ( 7 )
2.17.1.2. The hazard class of desensitised explosives comprises:
(a)
Solid desensitised explosives: explosive substances or mixtures, which are wetted with water or alcohols or are diluted with other substances, to form a homogeneous solid mixture to suppress their explosive properties.
NOTE: This includes desensitisation achieved by formation of hydrates of the substances.
(b)
Liquid desensitised explosives: explosive substances or mixtures, which are dissolved or suspended in water or other liquid substances, to form a homogeneous liquid mixture to suppress their explosive properties.
2.17.2. Classification criteria
2.17.2.1. Any explosive while in a desensitised state shall be considered in this class unless, in that state:
(a)
It is intended to produce a practical explosive or pyrotechnic effect;
(b)
It has a mass explosion hazard according to test series 6 (a) or 6 (b) or the corrected burning rate according to the burning rate test described in part V, subsection 51.4 of the UN RTDG, Manual of Tests and Criteria is greater than 1 200 kg/min; or
(c)
The exothermic decomposition energy is less than 300 J/g.
NOTE 1: Substances or mixtures, which meet the criterion (a) or (b) in their desensitised state shall be classified as explosives (see Section 2.1). Substances or mixtures which meet the criterion (c) may fall within the scope of other physical hazard classes.
NOTE 2: The exothermic decomposition energy may be estimated using a suitable calorimetric technique (see section 20, sub-section 20.3.3.3 in Part II of the UN RTDG, Manual of Tests and Criteria).
2.17.2.2. Desensitised explosives shall be classified and packaged for supply and use in one of the four categories of this class depending on the corrected burning rate (A c ) using the test “burning rate test (external fire)” described in Part V, sub-section 51.4 of the UN RTDG, Manual of Tests and Criteria , according to Table 2.17.1:
Table 2.17.1.
Criteria for desensitised explosives
Category
Criteria
1
Desensitised explosives with a corrected burning rate (A C ) equal to or greater than 300 kg/min but not more than 1 200 kg/min
2
Desensitised explosives with a corrected burning rate (A C ) equal to or greater than 140 kg/min but less than 300 kg/min
3
Desensitised explosives with a corrected burning rate (A C ) equal to or greater than 60 kg/min but less than 140 kg/min
4
Desensitised explosives with a corrected burning rate (A C ) less than 60 kg/min
Note 1: Desensitised explosives shall be prepared so that they remain homogeneous and do not separate during normal storage and handling, particularly if desensitised by wetting. The manufacturer/supplier shall give information in the safety data sheet about the shelf-life and instructions on verifying desensitisation. Under certain conditions the content of desensitising agent (e.g. phlegmatiser, wetting agent or treatment) may decrease during supply and use, and thus, the hazard potential of the desensitised explosive may increase. In addition, the safety data sheet shall include advice on avoiding increased fire, blast or projection hazards when the substance or mixture is not sufficiently desensitised.
Note 2: Explosive properties of desensitised explosives shall be determined by test series 2 of the UN RTDG, Manual of Tests and Criteria, and shall be communicated in the safety data sheet.
Note 3: For the purposes of storage, supply and use, desensitised explosives do not fall additionally within the scope of Sections 2.1 (explosives), 2.6 (flammable liquids) and 2.7 (flammable solids).
2.17.3. Hazard communication
Label elements shall be used for liquid or solid substances or mixtures meeting the criteria for classification in this hazard class in accordance with Table 2.17.2.

In section 3.1.2.1, the introductory paragraph is replaced by the following:
‘3.1.2.1.
Substances can be allocated to one of four hazard categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric cut-off criteria as shown in the table below. Acute toxicity values are expressed as (approximate) LD 50 (oral, dermal) or LC 50 (inhalation) values or as acute toxicity estimates (ATE). While some in vivo methods determine LD 50 /LC 50 values directly, other newer in vivo methods (e.g. using fewer animals) consider other indicators of acute toxicity, such as significant clinical signs of toxicity, which are used as a reference to assign the hazard category. Explanatory notes are shown following Table 3.1.1.’

measurements of Immunoglobulin E (IgE) and other specific immunological parameters, for example in mice;
(b)
specific pulmonary responses in guinea pigs.
( 8 )
At present, recognised and validated animal models for the testing of respiratory hypersensitivity are not available. Under certain circumstances, data from animal studies may provide valuable information in a weight of evidence assessment.
"
( 9 )
The mechanisms by which substances induce symptoms of asthma are not yet fully known. For preventative measures, these substances are considered respiratory sensitisers. However, if on the basis of the evidence, it can be demonstrated that these substances induce symptoms of asthma by irritation only in people with bronchial hyper-reactivity, they shall not be considered as respiratory sensitisers .’

Germ cell mutagenicity means heritable gene mutations, including heritable structural and numerical chromosome aberrations in germ cells occurring after exposure to a substance or mixture.’
(k)
Section 3.5.1.1 is renumbered as follows:
‘3.5.1.2.
A mutation means a permanent change in the amount or structure of the genetic material in a cell. The term “mutation” applies both to heritable genetic changes that may be manifested at the phenotypic level and to the underlying DNA modifications when known (including specific base pair changes and chromosomal translocations).

Genotoxicity test results are usually taken as indicators for mutagenic effects.’

Section 3.5.2.3.5 is replaced by the following:
‘3.5.2.3.5.
In vivo somatic cell mutagenicity tests, such as:
—
mammalian bone marrow chromosome aberration test;
—
mammalian erythrocyte micronucleus test’

Section 3.6.1.1 is replaced by the following:
‘3.6.1.1.
Carcinogenicity means the induction of cancer or an increase in the incidence of cancer occurring after exposure to a substance or mixture. Substances and mixtures which have induced benign and malignant tumours in well performed experimental studies on animals are considered also to be presumed or suspected human carcinogens unless there is strong evidence that the mechanism of tumour formation is not relevant for humans.
Classification of a substance or mixture as posing a carcinogenic hazard is based on its intrinsic properties and does not provide information on the level of the human cancer risk which the use of the substance or mixture may represent.

Section 3.7.1.1 is replaced by the following:
‘3.7.1.1.
Reproductive toxicity means adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring, occurring after exposure to a substance or mixture. The definitions presented below are adapted from those agreed as working definitions in IPCS/EHC Document No 225, Principles for Evaluating Health Risks to Reproduction Associated with Exposure to Chemicals. For classification purposes, the known induction of genetically based inheritable effects in the offspring is addressed in Germ Cell Mutagenicity (Section 3.5), since in the present classification system it is considered more appropriate to address such effects under the separate hazard class of germ cell mutagenicity.
In this classification system, reproductive toxicity is subdivided into two main headings:
(a)
adverse effects on sexual function and fertility;
(b)
adverse effects on development of the offspring.
Some reproductive toxic effects cannot be clearly assigned to either impairment of sexual function and fertility or to developmental toxicity. Nonetheless, substances and mixtures with these effects shall be classified as reproductive toxicants with a general hazard statement.’
(p)
Section 3.7.2.5.1 is replaced by the following:
‘3.7.2.5.1.
A number of internationally accepted test methods are available; these include methods for developmental toxicity testing (e.g. OECD Test Guideline 414) and methods for one or two-generation toxicity testing (e.g. OECD Test Guidelines 415, 416, 443).’

(r)
Section 3.8.3.4.1 is replaced by the following:
‘3.8.3.4.1.
Where there is no reliable evidence or test data for the specific mixture itself, and the bridging principles cannot be used to enable classification, then classification of the mixture is based on the classification of the ingredient substances. In this case, the mixture shall be classified as a specific target organ toxicant (specific organ specified), following single exposure, when at least one ingredient has been classified as a Category 1 or Category 2 specific target organ toxicant (single exposure) and is present at or above the appropriate generic concentration limit as mentioned in Table 3.8.3 for Category 1 and 2 respectively.’
(s)
In section 3.8.3.4, section 3.8.3.4.6 is added:
‘3.8.3.4.6.
In cases where the additivity approach is used for Category 3 ingredients, the “relevant ingredients” of a mixture are those which are present in concentrations ≥ 1 % (w/w for solids, liquids, dusts, mists, and vapours and v/v for gases), unless there is a reason to suspect that an ingredient present at a concentration < 1 % is still relevant when classifying the mixture for respiratory tract irritation or narcotic effects.’
(t)
Section 3.9.1.1 is replaced by the following:
‘3.9.1.1.
Specific target organ toxicity-repeated exposure means specific toxic effects on target organs occurring after repeated exposure to a substances or mixture. All significant health effects that can impair function, reversible and irreversible, immediate and/or delayed are included. However, other specific toxic effects that are specifically addressed in sections 3.1 to 3.8 and 3.10 are not included here.’
(u)
Section 3.9.3.4.1 is replaced by the following:
‘3.9.3.4.1.
Where there is no reliable evidence or test data for the specific mixture itself, and the bridging principles cannot be used to enable classification, then classification of the mixture is based on the classification of the ingredient substances. In this case, the mixture shall be classified as a specific target organ toxicant (specific organ specified), following repeated exposure when at least one ingredient has been classified as a Category 1 or Category 2 specific target organ toxicant (repeated exposure) and is present at or above the appropriate generic concentration limit as laid out in Table 3.9.4 for Category 1 and 2 respectively.’

Section 3.10.1.3 is replaced by the following:
‘3.10.1.3.
Aspiration hazard means severe acute effects such as chemical pneumonia, pulmonary injury or death occurring after aspiration of a substance or mixture.’

In section 3.10.3.3 a new section is added:
‘3.10.3.3.1.1.
The “relevant ingredients” of a mixture are those which are present in concentrations ≥ 1 %.’

Section 3.10.3.3.1.1 is renumbered and replaced by the following:
‘3.10.3.3.1.2.
A mixture is classified as Category 1 when the sum of the concentrations of Category 1 ingredients is ≥ 10 % and the mixture has a kinematic viscosity ≤ 20,5 mm 2 /s, measured at 40 °C.’

Section 3.10.3.3.1.2 is renumbered and replaced by the following:
‘3.10.3.3.1.3.
In the case of a mixture which separates into two or more distinct layers, the entire mixture is classified as Category 1 if in any distinct layer the sum of the concentrations of Category 1 ingredients is ≥ 10 %, and it has a kinematic viscosity ≤ 20,5 mm 2 /s, measured at 40 °C.’

Part 4 is amended as follows:
Section 4.1.3.5.5.3.1 is replaced by the following:
‘4.1.3.5.5.3.1.
First, all components classified as Acute 1 are considered. If the sum of the concentrations (in %) of these components multiplied by their corresponding M-factors is ≥ 25 % the whole mixture is classified as Acute 1.’

Up to now, the calculation method is validated for mixtures containing up to six volatile components. These components may be flammable liquids like hydrocarbons, ethers, alcohols, esters (except acrylates), and water. It is however not yet validated for mixtures containing halogenated, sulphurous, and/or phosphoric compounds as well as reactive acrylates.

The mechanisms by which substances induce symptoms of asthma are not yet fully known. For preventative measures, these substances are considered respiratory sensitisers. However, if on the basis of the evidence, it can be demonstrated that these substances induce symptoms of asthma by irritation only in people with bronchial hyper-reactivity, they shall not be considered as respiratory sensitisers .’

Unstable explosives as defined in Section 2.1 can also be stabilised by desensitisation and consequently may be classified as desensitised explosives, provided all criteria of Section 2.17 are met. In this case the desensitised explosive shall be tested according to test series 3 (Part I of the UN RTDG, Manual of Tests and Criteria) because information about its sensitiveness to mechanical stimuli is likely to be important for determining conditions for safe handling and use. The results shall be communicated in the safety data sheet.
