Foreword

This revised standard adopts ISO 4730.2004 "Melaleuca oil, pine-4-ol type (tea tree oil)." This standard and ISO 4730. Compared to 2004, the main technical differences are as follows. --- Remove the ISO 4730.2004 sampling methods; --- Test Methods "Common test methods for spices of" national standards; --- Optical rotation by the "5 ° ~ 15 °" to "1 ° ~ 15 °", characterized by the component content of "1,8-cineole and other 15 components" to "1,8-cineole, pine-4-ol two component"; --- Increased inspection rules; --- For signs, packaging, transportation, storage and shelf life of the contents of specific provisions; --- Added Appendix B of tea (refined) oil representative and characteristic component content range. Appendix A of this standard and Appendix B is an informative annex. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee of Fragrance Flavor and Cosmetic (SAC/TC257) centralized. This standard was drafted.
