Note 1:?Unless exceptions are noted, mass fraction ranges can
be extended by using suitable reference materials. Extended ranges
must be verified by experimental means. This could include, but not
be limited to, Interlaboratory studies, Round Robin exercises, and
other validation approaches. See Guide E2857 for additional guidance.
1.2?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. 1.3?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.
