3.1 Biomass Biomass refers to various organisms formed through photosynthesis. NOTE. biomass includes all materials derived from life entities, such as. animals, plants and microorganisms, etc. 3.2 Bio-carbon Bio-carbon refers to modern organic carbon element. 3.3 Biomass Content Biomass content refers to the mass fraction of biomass in sample. 3.4 Renewable Resource Renewable resource refers to a resource that is replenished by natural processes at a rate commensurate with its utilization. 3.7 Biobased Content Biobased content refers to a percentage of the ratio of organic carbon radioactivity per gram of sample to organic carbon radioactivity per gram of modern carbon reference material. 3.8 Biocompatibility Biocompatibility refers to the property of life entity tissues in response to inactive foreign materials, and the compatibility between materials and the life entity tissues. 3.9 Biobased Material; BBM Biobased material refers to a material that uses biomass as the raw material or (and) obtained through biological manufacturing. 3.10 Biobased Chemicals Biobased chemicals refer to chemicals converted from biomass with the participation of microorganisms or through biochemical methods.4 Identification
4.1 Identification Method of Biobased Materials The identification method of biobased materials is shown in Figure 1. 4.2 Identification Method of Product Texture 4.2.1 General requirements When product identification is used, it shall be marked on the product or the outer package in accordance with the stipulations of 4.3. 4.2.2 Single-component product If the product is made of a single polymer, then, it shall be marked in accordance with the stipulations of 4.3.See Table 1 for identification examples of some polymers. 4.2.4 Products with additives1) 4.2.4.1 Products with fillers or reinforcing agents In terms of products with a single filler or a single reinforcing agent, the filler or reinforcing agent shall be marked together with the polymer. 4.2.4.2 Products with plasticizers In terms of products with plasticizers, add a hyphen after the abbreviation of polymer. Then, mark the symbol “P”, followed by the abbreviation of plasticizer specified in GB/T 1844.3 enclosed in parentheses. 4.2.4.3 Products with flame retardants In terms of products with flame retardants, add a hyphen after the abbreviation of polymer. Then, mark the symbol “FR”, followed by the digital code of the flame retardant specified in ISO 1043-4 enclosed in parentheses. 4.3 Production of Identification The production of identification may adopt molding, printing, embossing, branding or other clear and indelible marking methods. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
