Description

ASTM D8420-21

Active Standard: Standard Test Method for Wax Appearance Temperature and Wax Disappearance Temperature of Petroleum Products and Liquid Fuels

ASTM D8420

Scope

1.1 This test method covers the determination of the wax appearance temperature and the wax disappearance temperature of petroleum products and liquid fuels by an automatic instrument using optical light scattering detection.

1.2 This test method is applicable to such materials as: crude oil, distillate fuels, residual fuels such as No. 6 Fuel Oil, marine fuels such as VLSFO, and including mixtures of these fuels and liquid biofuels.

1.3 This test method covers the range of temperatures from –30 °C to +75 °C with temperature resolution of 0.1 °C.

1.4 This test method contains interim precision with repeatability only; a full ILS will be completed within five years of its approval.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
