drafting.

This document is modified to adopt ISO 9842.2003 "Rose Essential Oil (Damascena)".

Compared with ISO 9842.2003, this document has made the following structural adjustments.

---Chapter 4 corresponds to Chapter 4 in ISO 9842.2003, where 4.1 corresponds to 4.1~4.2 in ISO 9842.2003, adding 4.8,

Deleted 4.9~4.10 of ISO 9842.2003;

---Chapter 5 corresponds to Chapter 6 in ISO 9842.2003, which adds 5.1~5.2;

---Chapter 6 corresponds to Chapter 5 in ISO 9842.2003, which adds 6.1~6.2 and 6.4~6.5;

--- Deleted Appendix B in ISO 9842.2003.

The technical differences between this document and ISO 9842.2003 and their reasons are as follows.

---Changed the origin of rose essential oil (Damascena), determined to be made in China (see Chapter 1, Chapter 1 of ISO 9842.2003), to

disambiguation;

--- Regarding the normative reference documents, this document has made adjustments with technical differences to adapt to the technical conditions of our country, specific adjustments

as follows.

* Replaced ISO 279 (see 5.3) with GB/T 11540, which was modified to adopt international standards, and GB/T 14454.4 replaced

ISO 280 (see 5.4), GB/T 14454.5 replaced ISO 592 (see 5.5), GB/T 14454.7 replaced ISO 1041

(see 5.6), GB/T 14455.6 replaced ISO 709 (see 5.7);

* Replaced ISO 7609 (see 5.8) with GB/T 11538-2006, which is equivalent to adopting international standards, and replaced GB/T 26515.1

ISO 11024-1 (see 5.8.3);

* Deleted ISO /T R210 (see Chapter 7 of ISO 9842.2003), ISO /T R211 (see Chapter 7 of ISO 9842.2003

Chapter 7), ISO 212 (see Chapter 5 of ISO 9842.2003), ISO 11024-2 (see 6.6 of ISO 9842.2003);

* Added GB/T 14454.2 (see 5.2), GB/T 11538-2006 (see 5.8);

---Changed the physical and chemical indicators, deleted 4.9~4.10 in ISO 9842.2003, relative density 0.848~0.880 (20 degrees C/

20 degrees C) to 0.838~0.851 (25 degrees C/25 degrees C), and the refractive index 1.4520~1.4700 (20 degrees C) to 1.4557~

1.4606(25 degrees C), optical rotation -5°~-1.8°(20 degrees C) changed to -3.8°~-1.7°(25 degrees C), freezing point 16 degrees C~

23.5°C was changed to 19.6°C~23.4°C, ester value 7~24 was changed to 5.2~14.9, and the content of characteristic components was changed (see 4.3~

4.8, see 4.4~4.8 of ISO 9842.2003), based on the measured data of rose essential oil (Damascena) produced in China, improve

Operability;

--- Added the test of color (see 5.1) to improve the operability of the judgment;

--- Increased inspection rules (see Chapter 6) to enhance practicality;

--- Changed the requirements for marking, packaging, transportation, storage and shelf life (see Chapter 7, see Chapter 7 of ISO 9842.2003) to improve

Improve feasibility.
