适用范围:
This practice covers uniform procedures for determining and reporting application rates and distribution patterns from agricultural aircraft. The procedures covered deal with both fixed and rotary-wing aircraft equipped with either liquid or dry material distribution systems. The physical characteristics of the liquid or dry material have an effect on the application rate and the distribution patterns. If inert test solutions for materials are substituted for the materials to be applied, they shall have physical characteristics similar to those of the material to be applied. If toxic materials are used in the tests, all safety precautions prescribed. A complete procedure shall consist of five parts: the first part is the determination of the output rate from the aircraft system, the second part involves the determination of the swath distribution pattern by recovery of the applied materials from suitable collectors, the third part covers the determination of usable swath width for field applications, the fourth part discusses the determination of the rate of application of the spray mixture or dry material, and the fifth and last part is the determination of the uniformity of distribution of several swaths.1.1 This practice covers uniform procedures for determining and reporting application rates and distribution patterns from agricultural aircraft. This practice should not be used for making biological performance tests.1.2 The procedures covered deal with both fixed and rotary-wing aircraft equipped with either liquid or dry material distribution systems.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.4 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.1.5 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.
