ANNEX XI: |
GENERAL RULES FOR ADAPTATION OF THE STANDARD TESTING REGIME SET OUT IN ANNEXES VII TO X |
Annexes
VII to
X set out the information requirements for all
substances manufactured or imported in quantities of:
- one tonne or more in accordance with Article
12(1)(a),
- 10 tonnes or more in accordance with Article
12(1)(c),
- 100 tonnes or more in accordance with Article
12(1)(d), and
- 1000 tonnes or more in accordance with Article
12(1)(e).
In addition to the specific rules set out in column 2 of Annexes
VII to
X, a registrant may adapt the standard testing regime in accordance with the general rules set out in Section 1 of this Annex.
Under dossier
evaluation the
Agency may assess these adaptations to the standard testing regime.
1. TESTING DOES NOT APPEAR SCIENTIFICALLY NECESSARY
1.1. Use of existing data
1.1.1. Data on physical-chemical properties from experiments not carried out according to GLP or the test methods referred
to in Article
13(3)
Data shall be considered to be equivalent to data generated by the corresponding test methods referred to in Article
13(3) if the following conditions are met:
(1) adequacy for the purpose of classification and labelling and/or risk assessment;
(2) sufficient documentation is provided to assess the adequacy of the
study; and
(3) the data are valid for the endpoint being investigated and the
study is performed using an acceptable level of quality assurance.
1.1.2. Data on human health and environmental properties from experiments not carried out according to GLP or the test methods
referred to in Article
13(3)
Data shall be considered to be equivalent to data generated by the corresponding test methods referred to in Article
13(3) if the following conditions are met:
(1) adequacy for the purpose of classification and labelling and/or risk assessment;
(2) adequate and reliable coverage of the key parameters foreseen to be investigated in the corresponding test methods referred
to in Article
13(3);
(3) exposure duration comparable to or longer than the corresponding test methods referred to in Article
13(3) if exposure duration is a relevant parameter; and
(4) adequate and reliable documentation of the
study is provided.
1.1.3. Historical human data
Historical human data, such as epidemiological
studies on exposed populations, accidental or occupational exposure data and clinical
studies, shall be considered.
The strength of the data for a specific human health effect depends, among other things, on the type of analysis and on the
parameters covered and on the magnitude and specificity of the response and consequently the predictability of the effect.
Criteria for assessing the adequacy of the data include:
(1) the proper selection and characterisation of the exposed and control groups;
(2) adequate characterisation of exposure;
(3) sufficient length of follow-up for disease occurrence;
(4) valid method for observing an effect;
(5) proper consideration of bias and confounding factors; and
(6) a reasonable statistical reliability to justify the conclusion.
In all cases adequate and reliable documentation shall be provided.
1.2. Weight of evidence
There may be sufficient weight of evidence from several independent sources of information leading to the assumption/conclusion
that a substance has or has not a particular dangerous property, while the information from each single source alone is regarded
insufficient to support this notion.
There may be sufficient weight of evidence from the use of newly developed test methods, not yet included in the test methods
referred to in Article
13(3) or from an international test method recognised by the Commission or the
Agency as being equivalent, leading to the conclusion that a substance has or has not a particular dangerous property.
Where sufficient weight of evidence for the presence or absence of a particular dangerous property is available:
- further testing on vertebrate animals for that property shall be omitted,
- further testing not involving vertebrate animals may be omitted.
In all cases adequate and reliable documentation shall be provided.
1.3. Qualitative or Quantitative structure-activity relationship ((Q)SAR)
Results obtained from valid qualitative or quantitative structure-activity relationship models ((Q)SARs) may indicate the
presence or absence of a certain dangerous property. Results of (Q)SARs may be used instead of testing when the following
conditions are met:
- results are derived from a (Q)SAR model whose scientific validity has been established,
- the substance falls within the applicability domain of the (Q)SAR model,
- results are adequate for the purpose of classification and labelling and/or risk assessment, and
- adequate and reliable documentation of the applied method is provided.
The
Agency in collaboration with the Commission,
Member States and interested parties shall develop and provide guidance in assessing which (Q)SARs will meet these conditions and provide
examples.
Results obtained from suitable
in vitro methods may indicate the presence of a certain dangerous property or may be important in relation to a mechanistic understanding,
which may be important for the assessment. In this context, "suitable "means sufficiently well developed according to internationally
agreed test development criteria (e.g. the European Centre for the Validation of Alternative Methods (ECVAM)) criteria for
the entry of a test into the prevalidation process). Depending on the potential risk, immediate confirmation requiring testing
beyond the information foreseen in Annexes
VII or
VIII or proposed confirmation requiring testing beyond the information foreseen in Annexes
IX or
X for the respective tonnage level may be necessary.
If the results obtained from the use of such
in vitro methods do not indicate a certain dangerous property, the relevant test shall nevertheless be carried out at the appropriate
tonnage level to confirm the negative result, unless testing is not required in accordance with Annexes
VII to
X or the other rules in this Annex.
Such confirmation may be waived, if the following conditions are met:
(1) results are derived from an
in vitro method whose scientific validity has been established by a validation
study, according to internationally agreed validation principles;
(2) results are adequate for the purpose of classification and labelling and/or risk assessment; and
(3) adequate and reliable documentation of the applied method is provided.
1.5. Grouping of
substances and read-across approach
Substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern
as a result of structural similarity may be considered as a group, or "category "of
substances. Application of the group concept requires that physicochemical properties, human health effects and environmental effects
or environmental fate may be predicted from data for reference substance(s) within the group by interpolation to other
substances in the group (read-across approach). This avoids the need to test every substance for every endpoint. The
Agency, after consulting with relevant stakeholders and other interested parties, shall issue guidance on technically and scientifically
justified methodology for the grouping of
substances sufficiently in advance of the first
registration deadline for
phase-in substances.
The similarities may be based on:
(1) a common functional group;
(2) the common precursors and/or the likelihood of common breakdown products via physical and biological processes, which
result in structurally similar
chemicals; or
(3) a constant pattern in the changing of the potency of the properties across the category.
If the group concept is applied,
substances shall be classified and labelled on this basis.
In all cases results should:
- be adequate for the purpose of classification and labelling and/or risk assessment,
- have adequate and reliable coverage of the key parameters addressed in the corresponding test method referred to in Article
13(3),
- cover an exposure duration comparable to or longer than the corresponding test method referred to in Article
13(3) if exposure duration is a relevant parameter, and
- adequate and reliable documentation of the applied method shall be provided.
2. TESTING IS TECHNICALLY NOT POSSIBLE
Testing for a specific endpoint may be omitted, if it is technically not possible to conduct the
study as a consequence of the properties of the substance: e.g. very volatile, highly reactive or unstable
substances cannot be used, mixing of the substance with water may cause danger of fire or explosion or the radio-labelling of the substance
required in certain
studies may not be possible. The guidance given in the test methods referred to in Article
13(3), more specifically on the technical limitations of a specific method, shall always be respected.
3. SUBSTANCE-TAILORED EXPOSURE-DRIVEN TESTING
3.1. Testing in accordance with Sections 8.6 and 8.7 of Annex
VIII, Annex
IX and Annex
X may be omitted, based on the
exposure scenario(s) developed in the Chemical Safety Report.
3.2.
In all cases, adequate justification and documentation shall be provided. The justification shall be based on a
thorough and rigorous exposure assessment in accordance with section 5 of Annex I and shall meet any one of
the following criteria:
(a) the manufacturer or importer demonstrates and documents that all of the following conditions are fulfilled:
(i) the results of the exposure assessment covering all relevant exposures throughout the life cycle of the
substance demonstrate the absence of or no significant exposure in all scenarios of the manufacture and all
identified uses as referred to in Annex VI section 3.5;
(ii) a DNEL or a PNEC can be derived from results of available test data for the substance concerned taking full
account of the increased uncertainty resulting from the omission of the information requirement, and that
DNEL or PNEC is relevant and appropriate both to the information requirement to be omitted and for risk
assessment purposes (76);
(iii) the comparison of the derived DNEL or PNEC with the results of the exposure assessment shows that
exposures are always well below the derived DNEL or PNEC;
(b) where the substance is not incorporated in an article the manufacturer or importer demonstrates and documents
for all relevant scenarios that throughout the life cycle strictly controlled conditions as set out in Article 18(4)(a)
to (f) apply;
(c) where the substance is incorporated in an article in which it is permanently embedded in a matrix or otherwise
rigorously contained by technical means, it is demonstrated and documented that all of the following conditions
are fulfilled:
(i) the substance is not released during its life cycle;
(ii) the likelihood that workers or the general public or the environment are exposed to the substance under
normal or reasonably foreseeable conditions of use is negligible; and
(iii) the substance is handled according to the conditions set out in Article 18(4)(a) to (f) during all manufac
turing and production stages including the waste management of the substance during these stages.
3.3 The specific conditions of use must be communicated through the supply chain in accordance with Article
31 or
32, as the case may be.
