ASTM members working to revise and reinstate test method for determining water in petroleum products, lubricating oils and additives

W. CONSHOHOCKEN, Pa., April 11, 2016 — ASTM International members are working to revise and reinstate a test method that helps determine how much water is in various petroleum products (D6304-04, Standard Test Method for Determination of Water in Petroleum Products, Lubricating Oils, and Additives by Coulometric Karl Fischer Titration).

Knowing the water content in these products helps manufacturers and buyers predict their quality and performance characteristics, while also helping prevent premature corrosion and wear.

The revision will clarify the amount of primary standard (i.e., water) needed, update and improve specifications in the water evaporator procedure, and harmonize the standard with other widely use “Karl Fischer” standards that determine water in crude oil.

This specification was recently withdrawn in accordance with ASTM International’s “Regulations Governing ASTM Technical Committees” (section 10.6.3), which require that standards be updated no later than the eight year since the last approval date. Subcommittee D02.02.10 on Sediment and Water (part of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants) has been continually working to revise and reinstate the standard since before its withdrawal.

Importantly, ASTM maintains electronic versions of all its standards, including historical and withdrawn standards. Withdrawn standards can be referenced. These standards remain accessible for individual purchase online and through ASTM download subscriptions.

To purchase standards, visit www.astm.org and search by the standard designation, or contact ASTM Customer Relations (tel +1.877.909.ASTM; [email protected])
