ASTM D1160 is the ASTM standard for the distillation of petroleum products at reduced pressure. It provides a recognized test method for evaluating how certain petroleum materials distill under vacuum conditions, which can be important when normal atmospheric distillation may not be suitable. By focusing on reduced-pressure operation, the standard supports more consistent testing of higher-boiling materials and helps users compare results with greater confidence in laboratory and quality control settings.

ASTM D1160 standard overview

The ASTM D1160 standard addresses a distillation test method designed for petroleum products tested at reduced pressure. Its main purpose is to define a repeatable technical approach for measuring distillation behavior when lower pressure is needed to limit heating effects or support testing of higher-boiling samples. As an ASTM standard, it gives laboratories and product users a common reference for procedure, interpretation, and reporting, helping improve comparability across testing programs and procurement specifications.

Where is ASTM D1160 used?

This standard is commonly used in laboratory environments that evaluate petroleum products requiring reduced-pressure distillation. It is relevant wherever distillation characteristics must be measured without relying on standard atmospheric conditions, especially for materials that may be better assessed under vacuum. ASTM D1160 is often used in testing workflows tied to product qualification, incoming inspection, research and development, and routine quality checks for petroleum-based materials with higher boiling ranges.

Practical importance of ASTM D1160

ASTM D1160 matters because it helps bring consistency to a test method that depends on controlled pressure conditions and careful procedure. For laboratories, it supports repeatable results that can be used in product evaluation, specification checks, and compliance documentation. For buyers and suppliers, the standard can reduce ambiguity when comparing test data and help support more reliable technical decisions. Using ASTM D1160 also helps limit risk from inconsistent methods in critical testing programs.
