1.1 该术语用于与包含生物衍生材料的生物理性相关的测试方法、规范、指南和实践中，或者，如果合成，该材料必须在结构上类似于生物发生的材料，并且在功能上与生物发生的材料相同，立体化学异构体比率之间存在微小差异。编写这些定义是为了确保正确理解和解释与这些材料及其用途相关的标准。本标准中包含的术语包括来自动物、植物、微生物或矿物的材料或产品，并侧重于功能性或营销性声明，或两者兼而有之。

1.1 This terminology is used in test methods, specifications, guides, and practices related to biorationals comprising biologically-derived materials or, if synthesized, the material must be structurally similar and functionally identical to a biologically occurring material with minor differences between the stereochemical isomer ratios. These definitions are written to ensure that standards related to these materials and their uses are properly understood and interpreted. Terms included in this standard cover materials or products derived from animals, plants, microorganisms, or minerals and focus on functional or marketing claims, or both.
