BS EN 17136:2019给出了内陆水域样本中大型无脊椎动物丰度的定量估计和鉴定指南。该程序涉及来自自然栖息地或人工基质的保存和未保存样品的预处理（清洗）、亚取样、分类和最终鉴定，以及将其运送至实验室的过程。为DNA分析的保存提供了具体指导。交叉引用:EN ISO/IEC 17025:2017EN 16164EN ISO 10870EN 16493EN 14996购买时可用的所有现行修订版均包含在本文件的购买中。

BS EN 17136:2019 gives guidance on the quantitative estimation of abundance and identification of macroinvertebrates in samples taken from inland waters. The procedure deals with pre-treatment (cleaning), sub-sampling, sorting, and final identification of organisms from preserved and unpreserved samples originating from natural habitats or artificial substrates and their transport to the laboratory. Specific guidance is given for preservation for DNA-analysis.Cross References:EN ISO/IEC 17025:2017EN 16164EN ISO 10870EN 16493EN 14996All current amendments available at time of purchase are included with the purchase of this document.
