What is BS EN ISO 4387:2021?

The BS EN ISO 4387:2021 is a standard that provides guidelines and requirements for the characterization of droplet or particle size distribution in sprays. This standard is applicable to various spraying systems, including agricultural sprayers, industrial sprayers, and medical inhalers. It is important to understand the key elements of this standard in order to accurately measure and assess spray characteristics. This article will delve into the details of the BS EN ISO 4387:2021, discussing its scope, methodology, and significance in different application areas.

Scope of BS EN ISO 4387:2021

The BS EN ISO 4387:2021 sets out a standardized approach for measuring and evaluating the size distribution of droplets or particles produced by spraying devices. The standard defines specific techniques and procedures to be followed when conducting measurements. It covers a wide range of spray systems, including hydraulic sprayers, air-assisted sprayers, and electrostatic sprayers, among others. Additionally, the standard specifies the requirements for reporting the measured data, ensuring consistency and comparability across different studies and applications.

Methodology of BS EN ISO 4387:2021

The BS EN ISO 4387:2021 recommends using laser diffraction as the primary method for determining droplet or particle size distribution in sprays. This technique involves passing a laser beam through the spray cloud and analyzing the light scattered by the droplets or particles. The intensity of the scattered light at different angles provides information about their size distribution. The standard outlines the instrument setup, calibration procedures, and measurement conditions necessary to obtain accurate and reliable results. Furthermore, it gives guidance on data analysis and interpretation to ensure the appropriate characterization of the spray.

Significance of BS EN ISO 4387:2021

The BS EN ISO 4387:2021 plays a crucial role in various industries where spray systems are extensively used. In agriculture, this standard helps in optimizing pesticide applications by ensuring the droplet size is suitable for efficient coverage and minimizing drift. In industrial applications, such as coating or cooling processes, the standard aids in achieving desired product quality and process efficiency. Moreover, in medical inhalers, adherence to this standard guarantees consistent droplet sizes for effective drug delivery. Overall, compliance with BS EN ISO 4387:2021 promotes improved spray system performance, environmental sustainability, and enhanced product outcomes.
