Foreword
This revised standard adopts ISO 3400.1997 "Cigarettes were in total alkaloids spectrophotometric determination" (in English).
This standard is based on ISO 3400.1997 re-drafted.
Taking into account China's national conditions, with ISO 3400.1997 as compared to the presence of the small number of technical differences in standards, these technical differences have been incorporated into positive
Wen, and they are involved in terms of the margin identified by a single vertical line. It is given in Appendix A of the technical differences and their reasons
List for reference.
For ease of use, and ISO 3400.1997 as compared to the standard made the following editorial changes.
--- Delete ISO 3400.1997 Foreword;
--- Delete ISO 3400.1997 reference standard;
--- Increasing the normative references;
--- Delete ISO 3400.1997 Annex A;
--- Delete ISO 3400.1997 Annex B;
--- Increase in Appendix A "of this standard and ISO 3400.1997 controls."
Appendix A of this standard is an informative annex.
This standard was proposed by the State Tobacco Monopoly Bureau.
This standard by the National Standardization Technical Committee on Tobacco (TC144) centralized.
This standard was drafted. National Tobacco Quality Supervision and Inspection Center.
