Standard Test Methods for Hydrogen Content of Light Distillates, Middle Distillates, Gas Oils, and Residua by Low-Resolution Nuclear Magnetic Resonance Spectroscopy
ORDER

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 D 3701 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 MethodPetroleum ProductsBoiling Range, °C (°F) (approximate)
A Light Distillates15-260 (60-500)
B Middle Distillates,200-370 (400-700)
Gas Oils370-510 (700-950)
C Residua510+ (950+ )

1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 6.1.
