BS EN 16695:2015规定了估算海洋和海洋生物量的程序 淡水浮游植物分类群使用倒置显微镜（根据 EN 15204），考虑到一些异养原生生物（<100µm），这些原生生物在 常规浮游动物分析和底栖微藻，可在远洋水样中发现。本欧洲标准描述了测量电池尺寸和 计算细胞或计算单位体积，以估计浮游植物样本中的生物体积。 这 应使用协调的几何形状分配来完成，以避免错误。交叉引用:EN 15204EN 15972EN 16698EN ISO/IEC 17025ISO/IEC 17025DIN 38402-45:2014EN 14996购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN 16695:2015 specifies a procedure for the estimation of biovolume of marine and freshwater phytoplankton taxa using inverted microscopy (Utermohl technique according to EN 15204), in consideration of some heterotrophic protists (< 100 µm) that are not considered in routine zooplankton analysis and benthic microalgae, which can be found in pelagic water samples.This European Standard describes the necessary methods for measuring cell dimensions and for the calculation of cell or counting unit volumes to estimate the biovolume in phytoplankton samples. This shall be done using harmonized assignments of geometrical shapes to avoid errors.Cross References:EN 15204EN 15972EN 16698EN ISO/IEC 17025ISO/IEC 17025DIN 38402-45:2014EN 14996All current amendments available at time of purchase are included with the purchase of this document.
