T/SZFAA 13-2024 Plant protection intelligent aerial fogger

Scope

Scope: This document specifies the classification, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation, and storage of intelligent mist sprayers for plant protection. This document applies to the production, manufacturing, performance testing, and quality assessment of intelligent mist sprayers (hereinafter referred to as "misting machines") used for spraying liquid pesticides and fertilizers. Other types and applications of misting machines can be used as reference. Main technical content: I. General requirements The misting machine should be able to operate normally in a closed or windless environment with a temperature range of 5 °C to 45 °C and a relative humidity range of 25% to 95%. The protection grade of the machine's components in the operating environment should be no less than IPX4, and it should comply with the relevant requirements of GB/T 4208. All plastic, rubber, and metal parts of the misting machine that come into direct contact with pesticide solutions or mist should be made of corrosion-resistant materials. For the entire machine: 1. Start-up performance Under rated operating conditions, the misting machine should start up three times, each time successfully and without contact-induced vibration. 2. Output volume The manufacturer should specify the rated output volume of the misting machine in the user manual or other technical documents. For models equipped with output volume adjustment switches, the recommended output volume and switch scale positions should be indicated in the manual, and clear markings should be provided at the switch location. Under rated operating conditions, the actual output volume of the misting machine should not deviate by more than ±15% from the rated output volume. 3. Droplet diameter Under rated operating conditions, the median droplet volume diameter (VMD) should not exceed 50μm. 4. Droplet dispersion performance Under rated operating condi
