ASTM D7892-15<\/h3>\n

Historical Standard: Standard Test Method for Determination of Total Organic Halides, Total Non-Methane Hydrocarbons, and Formaldehyde in Hydrogen Fuel by Gas Chromatography\/Mass Spectrometry<\/h4>\n
\n

ASTM D7892<\/h4>\n

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

\n

1.1<\/span> The gas chromatography\/mass spectrometry (GC\/MS) procedure described in this method is used to determine concentrations of total organic halides and total non-methane hydrocarbons (TNMHC) by measurement of individual target halocarbons (Table 1<\/span>) and hydrocarbons (including formaldehyde, Table 1<\/span> and Table 2<\/span>), respectively. Measurement of these substances is required for application of SAE J2719 to hydrogen fuel quality where this fuel is intended for use in fuel cell vehicles. SAE 2719 states hydrogen fuel is expected to contain less than 0.05 \u00b5mole\/mole total halogenates (including organic halides), 2 \u00b5mole\/mole total non-methane hydrocarbons (C1 Basis, 3.2.16<\/span>) and 0.01 \u00b5mole\/mole formaldehyde.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Based upon the GC\/MS\/full scan analysis of a 400 mL hydrogen sample, the reporting limit (RL) is 0.001 \u00b5mole\/mole for each target compound listed in Table 1<\/span> and Table 2<\/span>, with the exception of 0.002 \u00b5mole\/mole for ethane and 0.002 \u00b5mole\/mole for ethene.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> Mention of trade names in this standard does not constitute endorsement or recommendation for use. Other manufacturers\u2019 equipment or equipment models can be used.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> The values stated in SI units are to be regarded as standard.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
