active, Most Current
Organization: AASHTO
Publication Date: 1 January 2021
Status: active
Page Count: 6
scope:

This test method covers the determination of the total heavy metal content of glass beads using X-ray fluorescence (XRF). Heavy metals include but are not limited to lead, antimony, and arsenic. This test method is intended as a quality assurance tool for agencies to verify the manufacturer's certified test results for heavy metals provided in accordance with Environmental Protection Agency testing methods 3052, 6010B, and 6010C as they relate to compliance with Section 1504 of MAP-21.

The values stated in SI units are to be regarded as the standard.

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.

The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of R 18 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with R 18 alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of R 18 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
