CONTAINED IN VOL. 11.05, 2016 Describes the determination of the relative extensional viscosity or Screen Factor (SF) of dilute agricultural spray mixes.

1.1 This test method covers the determination of the relative extensional viscosity or Screen Factor (SF) of dilute agricultural spray mixes.

1.2 The test can be used for tank mixes containing dissolved, emulsified or dispersed materials, or mixtures.

1.3 Results may be affected by the quality of the water used. Make-up water quality should therefore be specified in the presentation of results.

1.4 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination. Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice.

Note 1

References to the development of extensional viscosity from dissolved polymers, extensional viscosity effects on the droplet size distribution of sprays, and measurements of screen factor on recirculated spray mixes containing polymers are available.

1.5 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.
