Additional information
| Significance and Use | ||||||||||||||||||
|
5.1 Elemental analysis serves as a quality control measure for post-reactor studies, for additive levels in formulated resins, and for finished products. X-ray fluorescence spectrometry is an accurate and relatively fast method to determine mass fractions of multiple elements in polyethylene and polypropylene materials. |

|
1.1 This test method covers a general procedure for the determination of elemental content in polyolefins by wavelength-dispersive X-ray fluorescence (WDXRF) spectrometry, in mass fraction ranges typical of those contributed by additives, catalysts, and reactor processes. The elements covered by this test method include fluorine, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, calcium, titanium, chromium, and zinc in the composition ranges given in Table 1. 1.1.1 This test method does not apply to polymers specifically formulated to contain flame retardants including brominated compounds and antimony trioxide. 1.1.2 This test method does not apply to polymers formulated to contain high levels of compounds of vanadium, molybdenum, cadmium, tin, barium, lead, and mercury because the performance can be strongly influenced by spectral interferences or interelement effects due to these elements. Note 1: Specific methods and capabilities of users may vary
with differences in interelement effects and sensitivities,
instrumentation and applications software, and practices between
laboratories. Development and use of test procedures to measure
particular elements, mass fraction ranges or matrices is the
responsibility of individual users.
Note 2: One general method is outlined herein; alternative
analytical practices can be followed, and are attached in notes,
where appropriate.
1.2 The values stated in SI units are to be regarded as the standard. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 3: There is no known ISO equivalent to this standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
