ASTM E1391

ASTM E1391 is the ASTM guide that addresses the collection, storage, characterization, and manipulation of sediments for toxicological testing, along with guidance for selecting samplers used to collect benthic invertebrates. It provides a practical technical reference for handling sediment samples and supporting test integrity from field collection through laboratory preparation. For organizations working with environmental samples, this standard helps promote consistency, improve comparability, and support more reliable toxicology-related evaluation.

What is ASTM E1391?

ASTM E1391 is a standard guide focused on sediment sample handling and related sampling considerations for benthic invertebrate collection. Its scope is centered on how sediments are collected, stored, characterized, and manipulated when they will be used in toxicological testing. The guide also addresses selection of samplers for benthic invertebrate collection, which makes it useful for planning field and laboratory workflows. As an ASTM standard, it serves as a technical document that supports more consistent sample treatment and interpretation.

Where is ASTM E1391 used?

ASTM E1391 is commonly used in environmental testing programs where sediment samples must be taken from aquatic settings and prepared for toxicity-related evaluation. It is relevant to field sampling, sample transport, storage, and laboratory handling steps where maintaining representative sediment conditions matters. The guide may also support work involving benthic invertebrate collection, especially when selecting appropriate samplers for the task. In practice, it is used wherever careful sediment management is needed for standardized testing.

Why is ASTM E1391 important?

This standard is important because sediment testing depends on consistent sample collection and handling. ASTM E1391 helps reduce variation caused by differences in storage, characterization, or manipulation practices, which can affect toxicological results. It also supports better sampler selection for benthic invertebrate collection, helping users align tools with the intended sampling purpose. For procurement, quality control, and compliance-oriented work, the guide provides a shared technical basis that can improve repeatability and reduce risk in test programs.
