Introduction
EU on June 1, 2007 through legislation "chemicals Registration, Evaluation, Authorization and Restriction" (hereinafter referred to as the REACH
Regulation), and in 2008 June 1 formally implemented. After the implementation of the regulation of chemicals entering the EU market for unified management. I
State response to the EU REACH regulations, developed a series of chemical safety standards equivalent to the relevant technical transformation of the EU REACH Regulation
content.
EU REACH Regulation and the United Nations' Globally Harmonized System of Classification and Labeling "(GHS) in order to reduce animal testing, clearly stipulates
Given the forecast (Q) SAR model prediction method can be used in certain circumstances the chemical properties.
This standard is in response to the EU REACH regulations on the use of technical indicators reference to OECD Guidance Document ENV/JM /
MONO (2007) 2 "(Quantitative) Structure - Activity Relationships [(Q) SAR] validated the model guidance document" (in English) and REACH Technology Law
Regulation EUR21866EN2005 "(quantitative) structure - activity relationship characteristics. initial guidance" (in English), and their relevant technical content
Exactly these documents, the establishment of a verification guide health toxicological properties of chemicals (Q) SAR model.
Validation Guidance chemical properties (Q) SAR model
Health toxicological properties
1 Scope
This standard specifies the verification guide health toxicological properties of chemicals (Q) SAR model.
This standard applies to existing as well as a variety of (Q) SAR model developed in the future.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
Structure or physical and chemical properties of molecules, or a part of the molecular structure of the molecule can represent special properties, it is used as (Q) SAR
Independent variables of the model.
2.2
It can be measured and therefore can be any physical model of chemical, biological or environmental effects.
2.3
The spatial extent of the response and chemical structure of the model at a given reliability conditions, chemical properties of the prediction.
2.4
The method of structural and/or chemical information from the physical and chemical properties and to predict the end of the process.
2.5
Compound used to create (Q) SAR model, obtained from the measurement of the nature or effects of related compounds.
2.6
Test sets and modeling corresponding to the set, is not included in the series of compounds refers to the centralized model, is used to (Q) SAR model predictions
Ability was evaluated.
3 Principles for the Validation
3.1 determine the end point;
3.2 explicit calculation algorithm;
3.3 determine the scope of application;
3.4 Evaluation meets the appropriate degree, applicable and predictive capabilities;
3.5 If possible, provide a mechanism to explain.
4 Verify the principles set forth
4.1 determine the end point
4.1.1 When using (Q) SAR model health toxicological properties of chemicals to predict common endpoint for health toxicology parameters, including
