A frequently asked question: Is there an international standard for spray nozzles?
At present there is no international standard for spray nozzle products. Nozzle manufacturers have developed their own performance standards, which apply to their products only. For this reason, manufacturers refer to the same type of spray nozzle, component, or characteristic by a variety of different terms. Units of measurement, such as those used to measure pressure and flow rate, also differ from catalog to catalog. For a detailed explanation of these terms, please see Glossary of SGS Terms. Concerning units of measurement, the information provided in this article is based on the ISO standard. If you would like to convert values into your preferred units of measurement, please use the Unit Converter function of the SGS.
