Summary of ASTM D95 – Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation

Title

ASTM D95-13(2018) (current active version) – Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation ASTM D95 is the definitive standard for measuring

Interpretation of Results

(Assumes water density = 1 g/mL – for crude oils, acceptable.) Crude oil production (upstream): Checking tank-bottom water

2. Scope and Significance

2.1 Scope

ASTM D95 covers the determination of water in crude petroleum, tars, and other petroleum products. It is applicable to materials where water is a distinct phase and not chemically combined with the sample. The method is capable of determining water content ranging from trace amounts up to significant percentages, typically exceeding 0.1% by volume.

• Crude oil production (upstream): Checking tank-bottom water.
• Petroleum refining: Monitoring feedstocks and intermediate streams.
• Fuel storage and distribution: Ensuring pipeline and barge transfers are not water-contaminated.
• Asphalt and bitumen testing: Water in asphalt causes foaming during paving.
• Lubricant manufacturing: High water in lube oils degrades additives.
