Significance and Use | ||
5.1 This test method is intended to provide a rapid means of determining the relative ability of a liquid agricultural spray mixture to spread on a test substrate. 5.2 This test method was validated using Parafilm M5.3 This test method will determine the relative spread of radii of water, fertilizers, oils, and mixtures of these carriers with surfactants. It is the user's responsibility to determine the validity of the test method with alternative liquids. 5.4 This test method will determine the relative spread radii of droplets over 30 s, 60 s, and 5 min. It is the user's responsibility to determine the validity of the test method at alternative spreading times. 5.5 This test method is appropriate for relative humidities within the range of 40 to 70 %. It is the user's responsibility to determine the validity of the test method at alternate relative humidities. 5.6 This test method is appropriate for temperatures within the range of 18 to 22°C. It is the user's responsibility to determine the validity of the test method at alternate temperatures. 5.7 This test method will determine the relative spread radii for droplets of 10 and 20 μL. It is the user's responsibility to determine the validity of the test method at alternate droplet sizes. |

1. Scope | ||
1.1 This test method covers the visual evaluation of the relative spread radius of liquid spray mixture droplets. 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 and health practices and determine the applicability of regulatory limitations prior to use. |
