Foreword

This standard is identical with the Organisation for Economic Co-operation and Development (OECD) Chemicals testing guidelines No. 432 (2004) "In vitro 3T3 Neutral Red uptake phototoxicity test "(in English). The editorial changes made the following standard. --- Increasing the scope and normative references partial section; --- Introduction to the OECD test methods portion and principles of consolidation; --- Know Before test and test methods OECD merger; --- Deleted the reference section of the OECD; --- Evaluation of the test results with reference to the test methods of the EU. Appendix A of this standard and Appendix B is an informative annex. This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points. This standard is drafted by. Guangdong CIQ. The main drafters of this standard. Cheng Shujun, Xuchong Hui, Jiao Hong, Wenqiao Ling, PAN Fang, Chen Qiang, Qin Yao, Li Qingxiang.

UVA (315nm ~ 400nm), UVB (280nm ~ 315nm) and UVC (100nm ~ 280nm). Some other definitions may be used; UVB and UVA boundaries typically 320nm, UVA can dispose of at 340nm UV-A1 and UV-A2. 3.1.4 Measuring total activity of a cell population parameters (such as lysosomal neutral red dye uptake activity), its value depends on the end point measured and Experimental design used, and related to the total number of cells and/or cell viability.
