ASTM D 7212 Document Information:
Title
Standard Test Method for Low Sulfur in Automotive Fuels by Energy-Dispersive X-ray Fluorescence Spectrometry Using a Low-Background Proportional Counter
ASTM International
Publication Date:
May 1, 2007
Scope:
This test method specifies an energy-dispersive X-ray
fluorescence (EDXRF) method for the determination of the total
sulfur content of automotive fuels with a concentration range from
7 mg/kg to 50 mg/kg.
The pooled limit of quantitation of this test method as obtained
by statistical analysis of interlaboratory test results is 7 mg/kg
sulfur.
The values stated in SI units are to be regarded as the
standard. The preferred concentration units are mg/kg sulfur.
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.
*A Summary of Changes section appears at the end of this
standard.
