About This Item
ASTM E394 is the standard test method for measuring iron in trace quantities using the 1,10-Phenanthroline method. It is used to support accurate low-level iron determination where small variations can matter in testing and quality control. By providing a recognized procedure for trace analysis, this standard helps users compare results more consistently and supports technical decisions based on reliable iron measurements.
What is ASTM E394?
ASTM E394, Standard Test Method for Iron in Trace Quantities Using the 1,10-Phenanthroline Method, describes a chemical test approach for determining very small amounts of iron. The method title indicates a colorimetric procedure centered on 1,10-Phenanthroline, which is commonly used in trace metal analysis. As an ASTM standard, it provides a structured reference for laboratories and technical teams that need a consistent way to evaluate iron levels in samples where precision and repeatability are important.
Where is ASTM E394 used?
This standard is commonly used in laboratory testing and analytical workflows where trace iron measurement is needed. It may be relevant in quality control, incoming material checks, and product evaluation when iron content must be monitored at low concentrations. ASTM E394 is especially useful in settings that rely on chemical analysis methods and documented test procedures, helping ensure that measurements are performed in a consistent and comparable way.
Why is ASTM E394 important?
ASTM E394 matters because trace iron can affect product performance, purity, and analytical interpretation even when present in very small amounts. A standardized test method supports more consistent results across laboratories and helps reduce uncertainty in reporting. For procurement, compliance, and quality programs, ASTM E394 provides a recognized technical basis for evaluating iron in trace quantities, which can improve confidence in test data and downstream decisions.
