ASTM D7343-12

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

This standard is issued under the fixed designation D7343; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This practice covers information relating to sampling, calibration and validation of X-ray fluorescence instruments for
elemental analysis, including all kinds of wavelength dispersive (WDXRF) and energy dispersive (EDXRF) techniques. This
practice includes sampling issues such as the selection of storage vessels, transportation, and sub-sampling. Treatment, assembly,
and handling of technique-specific sample holders and cups are also included. Technique-specific requirements during analytical
measurement and validation of measurement for the determination of trace elements in samples of petroleum and petroleum
products are described. For sample mixing, refer to Practice D5854. Petroleum products covered in this practice are considered
to be a single phase and exhibit Newtonian characteristics at the point of sampling.
1.2 Applicable Test Methods—This practice is applicable to the XRF methods under the jurisdiction of ASTM Subcommittee
D02.03 on Elemental Analysis:Analysis, D2622, D4294, D5059, D6334, D6443, D6445, D6481, D7039, D7212, and D7220 and
those under the jurisdiction of the Energy Institute’s Test Method Standardization Committee: IPCommittee (Table 1 228, IP 336,
IP 352, IP 407, IP 433, IP 447, IP 475, IP ). Some of these methods are technically equivalent though they may differ in details
(Table 2489, IP 496, IP 497, IP 503, IP 531, and IP 532.).
1.3 Applicable Fluids—This practice is applicable to petroleum and petroleum products with vapor pressures at sampling and
storage temperatures less than or equal to 101 kPa (14.7 psi). Use Practice D4057 or IP 475 to sample these materials. Refer to
Practice D5842 when sampling materials that also require Reid vapor pressure (RVP) determination.
1.4 Non-applicable Fluids—Petroleum products whose vapor pressure at sampling and sample storage conditions are above 101
kPa (14.7 psi) and liquefied gases (that is, LNG, LPG, etc.) are not covered by this practice.
1.5 Sampling Methods—The physical sampling and methods of sampling from a primary source are not covered by this guide.
It is assumed that samples covered by this practice are a representative sample of the primary source liquid. Refer to Practice
D4057 or IP 475 for detailed sampling procedures.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.7 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.
