ASTM D5164

ASTM D5164 is the ASTM standard for the Standard Specification for Propylene Glycol and Dipropylene Glycol. It provides a technical basis for describing these materials in a consistent way, which helps buyers, suppliers, and users align on product expectations. For applications that rely on glycols as raw materials or formulation ingredients, a clear specification supports more reliable procurement, quality control, and product evaluation. This makes ASTM D5164 a practical reference for managing consistency and compliance.

What is ASTM D5164?

ASTM D5164 defines a specification focused on propylene glycol and dipropylene glycol. As a standard specification, it is intended to describe the material in terms that can be used for commercial and technical agreement, rather than to serve as a test method or broad performance guide. The document is useful when parties need a common reference for material identity and quality expectations. In that role, ASTM D5164 supports clearer communication between producers, purchasers, and users.

Where is ASTM D5164 used?

This standard is commonly used anywhere propylene glycol or dipropylene glycol are bought, sold, received, or specified for further use. That may include manufacturing, formulation, and quality assurance workflows where consistent material characteristics matter. It is especially relevant in procurement and incoming inspection processes, where a formal specification helps confirm that supplied material matches the agreed requirements. ASTM D5164 can also support technical documentation and contract language for these glycol products.

Why is ASTM D5164 important?

ASTM D5164 matters because it helps reduce ambiguity when specifying two widely used glycol materials. A recognized standard can improve consistency across suppliers, support testing and acceptance decisions, and make purchasing specifications easier to manage. It also helps organizations document what they expect from the material, which can lower the risk of misunderstandings during sourcing or quality review. For many operations, that clarity is valuable for both compliance and day-to-day process control.
