3 Terms and definitions

The following terms and definitions defined in LY/T 2904-2017 and LY/T 3137 apply to this document.

Aquilaria wood

Agarwood

Xylem tissue of agarwood species.

[Source. LY/T 2904-2017, 3.2] 3.2 Agarwood the natural mixture of xylem tissue and its secretions formed during the growth of agarwood species, and secreted the physical characteristics should meet the requirements specified in LY/T 2904.

[Source. LY/T 2904-2017, 3.3, with modification] 3.3 Ethanol extractive of agarwood A substance soluble in 95% ethanol in agarwood. Mainly include 2-(2-phenethyl) chromone compounds, sesquiterpenoids, Aromatic compounds and fatty acids, etc.

[Source. LY/T 2904-2017, 3.4, with modification] 3.4 Aquilaria wood with low agarwood resin Agarwood ethanol extract content is greater than or equal to 4.0%, but less than 10.0% agarwood.

Aquilaria wood without agarwood resin Agarwood with ethanol extract content of less than 4.0%.

Agarwood grading

According to the external sensory characteristics and internal quality of Agarwood, the quality level is divided.

Agarwood resin-rich side Agarwood is rich in secretions on the surface.

4 Requirements

4.1 The appearance should be clean, free of staining, waxing, and mildew.

4.2 The moisture content is <=10.0%.

4.3 The characteristics of xylem structure and secretions should meet the requirements of LY/T 2904.

5 Test method

6 Sampling and sampling

7 Judgment

7.1 On the premise that the sample meets the requirements of 4.1, 4.2 and 4.3, the inspection results meet all the requirements of the corresponding grade.

When required, determine the corresponding level according to Table 1; if the test result cannot meet the requirements of the corresponding level at the same time, the lowest level in the item is judged.

7.2 When there is a dispute over the inspection result, the sample should be re-randomized or re-randomly doubled from the same batch of products, and the disputed items should be reviewed.

The results of the re-inspection shall prevail.

8 Marking, transportation and storage
