(Test Method)Standard Test Method for Nonvolatile Matter of Agricultural Adjuvant Solutions by Thermogravimetry
Standard Test Method for Nonvolatile Matter of Agricultural Adjuvant Solutions by Thermogravimetry
SIGNIFICANCE AND USE
5.1 This test method is intended for use in quality control, material screening, and related problem solving where a nonvolatile content is desired or a comparison can be made with a known material of the same type.
5.2 The parameters described may be altered to suit a particular analysis, provided the changes are noted in the report.
SCOPE
1.1 This test method covers the determination of the non-volatile matter of agricultural tank mix adjuvant solutions by thermogravimetry.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
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.
