3 Terms and definitions

The terms and definitions as defined in GB/T 28202-2011 AND the following terms and definitions apply to this document.

4 Classification and coding principles

4.1 In this standard, it classifies materials in two ways: by use and by attributes.

4.2 In this standard, it divides furniture materials into four levels: master category, large category, medium category, small category; compiles a uniform code. The code consists of 8 digits.

5 Coding method

5.1 The codes of master categories, large categories, medium categories, small categories in this standard shall be coded sequentially, starting from 01. When the levels of this standard are no longer further divided, the codes shall be supplemented with "00", until the 8th digit.

5.2 For each level of this standard, it needs setting up containment items which have the word "other", as needed. In order to facilitate identification, the code mantissa of the containment item is required to be "99" in principle.

5.3 The code structure diagram of this standard is as shown in Figure 1.

Figure 1 -- Structure diagram of code Example: The code of master category is represented by 2 digits, which represent the different material categories that make up the furniture, such as furniture base material, furniture hardware accessories, etc. The code of large category is represented by 4 digits, which represent the specific material category after the further division of master category, such as wood, metals, plastics, etc. The code of medium category is represented by 6 digits, which represent various materials that are further divided from the materials that are organically connected to the large category, such as solid wood sawn timber after simple primary processing of logs AND solid wood panels after in- depth processing. The code of small category is represented by 8 digits, which Code of small category, which is represented by 8 digits Code of medium category, which is represented by 6 digits Code of large category, which is represented by 4 digits Code of master category, which is represented by 2 digits
