About This Item
ASTM D87 is the standard test method for determining the melting point of petroleum wax using a cooling curve. It provides a consistent way to evaluate how a wax sample solidifies and the temperature range associated with melting behavior. This matters for quality control, product comparison, and specification compliance because melting point can influence handling, processing, and end-use performance in petroleum wax applications.
Overview of ASTM D87
The Standard Test Method for Melting Point of Petroleum Wax (Cooling Curve) is used to measure a key physical property of petroleum wax by observing the cooling behavior of the sample. As an ASTM standard, it supports repeatable laboratory testing and helps users compare results across batches, suppliers, and manufacturing runs. ASTM D87 is generally relevant when a controlled melting point value is needed for technical evaluation, acceptance testing, or internal quality documentation.
Common use cases of ASTM D87
This standard is commonly used in laboratories and quality control settings that test petroleum wax products. It may be applied during incoming material inspection, production monitoring, and finished-product evaluation where melting point is a routine specification. ASTM D87 is also useful when comparing wax grades or verifying that a material meets a purchasing requirement. The cooling curve method gives users a practical way to assess thermal behavior in a consistent, standards-based manner.
Benefits of using ASTM D87
Using ASTM D87 helps create more consistent melting point measurements for petroleum wax, which supports reliable product evaluation and clearer communication between buyers and suppliers. It can reduce uncertainty in acceptance testing and help maintain uniform quality control practices. Because the method is standardized, it also supports compliance documentation and makes test results easier to compare across different laboratories or production lots. For technical teams, that consistency can improve decision-making and reduce risk.
