ASTM E1199

ASTM E1199 is a technical standard for sampling zooplankton with a Clarke-Bumpus plankton sampler. It provides a common reference for collecting plankton samples in a controlled and repeatable way, helping users work with a defined approach when evaluating aquatic environments. As an ASTM standard, it supports consistency in field sampling and helps reduce variability when zooplankton data are used for monitoring, comparison, or documentation.

Purpose of ASTM E1199

The purpose of ASTM E1199 is to describe a standardized practice for sampling zooplankton using a Clarke-Bumpus plankton sampler. This makes the title’s method and equipment central to its use: a defined sampler, a defined target organism group, and a repeatable field approach. In practical terms, the standard helps users follow a consistent sampling practice so results are more comparable across locations, projects, and time periods when zooplankton collection is needed.

Common use cases of ASTM E1199

This standard is commonly used in aquatic sampling work where zooplankton collection needs to be performed with a Clarke-Bumpus plankton sampler. It may support field studies, environmental monitoring, and other water-quality or biological assessment activities that depend on comparable sample collection. ASTM E1199 is especially relevant when teams need a documented method for obtaining zooplankton samples in a way that is consistent and suitable for later evaluation or reporting.

Why ASTM E1199 matters

ASTM E1199 matters because standardized sampling practice helps improve consistency, traceability, and confidence in zooplankton data. When sample collection is performed in a uniform way, it is easier to compare results, support quality control, and reduce procedural differences that can affect interpretation. For procurement, testing programs, and environmental documentation, the standard provides a clear technical basis for using a Clarke-Bumpus plankton sampler in a repeatable and defensible manner.
