Wax Apperance Temperature

ASTM D5773 (IP 446), ASTM D2500 (IP 219 / ISO 3015) equivalent
Also known as cloud point, wax appearance temperature is the temperature at which a crude oil sample first precipitates solid wax as it is being cooled under prescribed test conditions.

Phase Technology’s new WAT-70Xi analyzer revolutionizes the upstream and midstream oil industries with the world’s first and only totally automatic process to measure WAT and WDT of crudes. Based upon ASTM D5773, our proprietary optical light scattering technique detects phase changes with extreme sensitivity and accuracy.

This important scientific break-through means that even the darkest, most opaque samples can now be easily tested, with 1.0° C precision. The Phase Technology WAT-70Xi offers a considerable efficiency advantage—just load the sample, and the analyzer does the rest, with tests completed in just 20-40 minutes. There’s no time-consuming manual set-up needed, and cleaning is done automatically after each test.
