(Test Method)Standard Test Methods for Hydrogen Content of Light Distillates, Middle Distillates, Gas Oils, and Residua by Low-Resolution Nuclear Magnetic Resonance Spectroscopy
Standard Test Methods for Hydrogen Content of Light Distillates, Middle Distillates, Gas Oils, and Residua by Low-Resolution Nuclear Magnetic Resonance Spectroscopy
SIGNIFICANCE AND USE
5.1 The hydrogen content represents a fundamental quality of a petroleum product that has been correlated with many of the performance characteristics of that product.
5.2 This test method provides a simple and more precise alternative to existing test methods, specifically combustion techniques (Test Methods D5291) for determining the hydrogen content on a range of petroleum products.
SCOPE
1.1 These test methods cover the determination of the hydrogen content of petroleum products ranging from atmospheric distillates to vacuum residua using a continuous wave, low-resolution nuclear magnetic resonance spectrometer. (Test Method D3701 is the preferred method for determining the hydrogen content of aviation turbine fuels using nuclear magnetic resonance spectroscopy.)
1.2 Three test methods are included here that account for the special characteristics of different petroleum products and apply to the following distillation ranges:
Test Method
Petroleum Products
Boiling Range, °C (°F)
(approximate)
A
Light Distillates
15–260 (60–500)
B
Middle Distillates
200–370 (400–700)
Gas Oils
370–510 (700–950)
C
Residua
510+ (950+ )
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. The preferred units are mass %.
1.4 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. For specific warning statements, see Sections 7.2 and 7.4.
1.5 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.

4.1 A test specimen is compared in a continuous wave, low-resolution nuclear magnetic resonance (NMR) spectrometer with a
reference standard sample. The spectrometer records in a nondestructive fashion the absolute concentration of hydrogen atoms in
the reference standard and test sample. The absolute hydrogen concentrations reported by the integrator on the NMR instrument
for the standard and test specimens are used as a means of comparing the theoretical hydrogen content of the standard with that
of the sample, the result being expressed as the hydrogen content (on a mass % basis) of the sample.
