About This Item
ASTM E2193 is the ASTM standard for evaluating the ultraviolet transmittance of monoethylene glycol using ultraviolet spectrophotometry. It provides a clear technical basis for measuring how much UV light passes through the material, which can help with product evaluation, consistency checks, and quality control. Because transmittance can reflect the presence of absorbent contaminants or other material differences, this standard is useful when comparing batches or verifying compliance with internal or procurement requirements.
Purpose of ASTM E2193
The purpose of ASTM E2193 is to define a consistent test method for determining the ultraviolet transmittance of monoethylene glycol by ultraviolet spectrophotometry. In practical terms, it supports repeatable measurement of a property that may be important to material assessment and specification control. As a technical document, it helps laboratories and buyers use a common approach when checking whether a sample meets expected optical or purity-related criteria. ASTM E2193 therefore supports more reliable and comparable test results.
Common use cases of ASTM E2193
This standard is commonly used in laboratory testing and incoming material verification for monoethylene glycol. It may be applied when a purchaser, supplier, or quality team needs a consistent method for measuring UV transmittance as part of product evaluation. ASTM E2193 is also relevant in settings where spectrophotometric data are used to compare lots, monitor material changes, or support acceptance decisions tied to technical requirements. Its value is strongest when repeatable testing is needed across different samples or laboratories.
Why ASTM E2193 matters
ASTM E2193 matters because it gives organizations a recognized way to measure ultraviolet transmittance in monoethylene glycol without relying on informal or inconsistent practices. That helps improve confidence in test results, supports better procurement decisions, and reduces the risk of accepting material that does not meet expectations. For quality control and compliance workflows, using a standard test method can make results easier to document, compare, and defend. ASTM E2193 also helps align internal testing with a common ASTM framework.
