ASTM D7171-05-Reapproved2011<\/h3>\n

Historical Standard: Standard Test Method for Hydrogen Content of Middle Distillate Petroleum Products by Low-Resolution Pulsed Nuclear Magnetic Resonance Spectroscopy<\/h4>\n
\n

ASTM D7171<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of the hydrogen content of middle distillate petroleum products using a low-resolution pulsed nuclear magnetic resonance (NMR) spectrometer. The boiling range of distillates covered by the test method is 150 to 390\u00b0C. While this test method may be applicable to middle distillates outside this boiling range, in such cases the precision statements may not apply. The test method is generally based on Test Methods D 3701 and D 4808, with a major difference being the use of a pulsed NMR spectrometer instead of a continuous wave NMR spectrometer.<\/p>\n

1.2 The values stated in SI units are to be regarded as the standard. The preferred units are mass %.<\/p>\n

1.3 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.<\/p>\n
