About This Item
ASTM E1193 is the ASTM standard guide for conducting Daphnia magna life-cycle toxicity tests. It is intended to support consistent test planning and execution when evaluating how a substance or environmental sample may affect the full life cycle of this aquatic organism. By giving laboratories a shared technical framework, the guide helps improve comparability, repeatability, and confidence in test results used for environmental assessment and product evaluation.
Purpose of ASTM E1193
The purpose of ASTM E1193 is to guide users in performing Daphnia magna life-cycle toxicity tests in a controlled and reproducible way. As a standard guide, it generally addresses the overall conduct of the test rather than setting a product specification. This makes it useful for organizing test conditions, observing organism response across life stages, and supporting consistent interpretation of toxicity data. ASTM E1193 is especially relevant where dependable biological testing is needed for comparison and documentation.
Common use cases of ASTM E1193
This standard is commonly used in aquatic toxicology programs, environmental testing laboratories, and research settings that evaluate the effects of chemicals, effluents, or other water-related samples on Daphnia magna over its life cycle. It may also support method selection, study planning, and result reporting when long-term organism response is important. ASTM E1193 is a practical reference for teams that need a structured approach to biological test execution and data consistency.
Why ASTM E1193 matters
ASTM E1193 matters because life-cycle toxicity testing can be sensitive to test conditions, organism handling, and study design. Using a recognized ASTM standard helps promote consistency across laboratories and projects, which is important for compliance work, quality control, and product or sample evaluation. It also supports clearer communication of test methods and findings, helping reduce uncertainty when results are used for decision-making, screening, or environmental risk-related reviews.
