ASTM D1133 is the ASTM standard for the Standard Test Method for Kauri-Butanol Value of Hydrocarbon Solvents. It provides a common technical approach for measuring a solvent property associated with its interaction in the kauri-butanol test. This matters for buyers, laboratories, and quality teams that need a consistent way to evaluate and compare hydrocarbon solvents for specification review, product control, and application suitability.

Purpose of ASTM D1133

The purpose of ASTM D1133 is to define a standardized test method for determining the kauri-butanol value of hydrocarbon solvents. As an ASTM standard, it supports uniform test practice so results can be compared more reliably across suppliers, batches, and laboratories. The method is commonly used as part of solvent characterization and quality assessment, helping users apply a consistent technical basis when reviewing product performance or compliance expectations.

Common use cases of ASTM D1133

ASTM D1133 is commonly used when hydrocarbon solvents must be evaluated against a recognized test method during procurement, incoming inspection, or production quality control. It is relevant to laboratories and technical teams working with solvent products that require standardized characterization. The method may also support specification checking, lot-to-lot comparison, and routine testing where a documented measure of kauri-butanol value is needed for product evaluation or internal approval.

Why ASTM D1133 matters

This standard matters because it helps reduce ambiguity in how a key solvent property is measured and reported. Using ASTM D1133 can improve consistency between suppliers and end users, support clearer purchasing decisions, and strengthen quality control programs. For organizations that depend on hydrocarbon solvent performance, a recognized test method can also help limit risk, simplify compliance discussions, and make technical comparisons more dependable.
