ASTM E2043

ASTM E2043 is a test method for measuring the nonvolatile matter of agricultural adjuvant solutions by thermogravimetry. It provides a standardized way to evaluate the residue that remains after volatile components are removed, helping users compare product consistency and formulation strength. This makes the standard useful for quality control, product evaluation, and procurement decisions where a repeatable measure of nonvolatile content is needed.

What is ASTM E2043?

ASTM E2043, formally titled Standard Test Method for Nonvolatile Matter of Agricultural Adjuvant Solutions by Thermogravimetry, describes a laboratory approach for determining the nonvolatile portion of an agricultural adjuvant solution. The method uses thermogravimetric measurement to assess what remains after heating under defined conditions. In practice, it supports consistent testing of liquid adjuvant products by giving a repeatable basis for comparing samples and checking whether a product aligns with expected formulation characteristics.

Where is ASTM E2043 used?

This standard is commonly used in laboratory and quality assurance settings that handle agricultural adjuvant solutions. It is relevant wherever suppliers, formulators, or buyers need to measure nonvolatile matter in liquid products intended for agricultural applications. ASTM E2043 may be used during incoming inspection, batch release testing, or routine product evaluation when a controlled thermogravimetric method is needed to assess consistency across lots or formulations.

Why is ASTM E2043 important?

The standard matters because nonvolatile matter can be an important indicator of product composition and performance consistency. Using ASTM E2043 helps reduce variation in test results by providing a recognized method for measurement and reporting. That supports clearer communication between manufacturers, laboratories, and purchasers, and it can improve confidence in quality control decisions, specification checks, and compliance-related testing workflows.
