Work Item
ASTM WK95845
Revision of D2622-24a Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry
Rationale
The current version of D2622-24a utilizes statistically incorrect criteria for duplicate determination acceptance. This ballot corrects this requirement to be determinability instead of repeatability, as defined in ASTM D6300. The ILS associated with the current version of the standard did not use the incorrect repeatability requirement for the duplicate determinations, therefore a new ILS is not needed to correct this criteria. As the addition of the repeatability requirement was added after the precision statements were calculated, the balloted change will not affect the precision statements.
