本文件规定了藻类生产商、藻类产品行业、实验室或采集藻类和藻类产品样本的其他实体在定义自己的采样方案和采样协议时必须遵循的一套原则和规则。 在本文件中，藻类是一个功能群，包括微藻、大型藻类、蓝藻和迷宫菌。 由于藻类及其生产过程如此多样化，本文件未定义具体的采样程序和/或具体的采样协议。相反，本文件规定了组织在定义自己的取样程序和协议时应考虑的方面。 本文件描述了抽取代表性样品的时间和方式。有关微藻和大型藻类以及基于藻类的产品的干样品和湿样品的样品制备指南，请参考EN 17605:2022。 本文件用于收集用于商业或法律/监管目的的批次特征的样品。然而，本文件也可用于任何类型的藻类采样，包括生产过程中用于质量控制的样本。

This document specifies a set of principles and rules that algae producers, algae products industries, laboratories or other entities that collect algae and algae products samples can follow for the definition of their own sampling programs and sampling protocols. In the context of this document, algae are a functional group that include microalgae, macroalgae, cyanobacteria and Labyrinthulomycetes. As algae and their production processes are so diverse, this document does not define a specific sampling program and/or a specific sampling protocol. Instead, this document specifies the aspects that can be considered when defining its own sampling program and protocol. This document describes when, where and how to draw a representative sample. For guidance on sample preparation of dry and wet samples of micro- and macroalgae, and algae products, please refer to EN 17605. This document is to be used for the collection of samples for lot characterization for commercial or legal/regulatory purposes. However, this document can also be used for any type of sampling of algae, including samples for quality control during production.
