ISO 21191:2021 pdf download.Equipment for crop protection — Closed transfer systems (CTS) — Performance specification
1 Scope
This document specifies operator and environment-related safety requirements and the means of their verification for the design and construction of closed transfer systems (CTS) for liquid formulations of plant protection products (PPP)in 11 to 20 l containers.
In addition, it specifies the type of information on safe working practices including information about residual risks to be provided by the CTS manufacturer and specifies the maximum potential contamination during any single transfer operation.

[SOURCE: ISO 5681:2020, 3.1.16]
3.2 closed transfer system
CTS device or assembly of components, including the container to application equipment (3.1) interface, intended to wholly and partially transfer plant protection products or other compatible liquids from their original containers into application or mixing equipment by direct coupling or other engineering means of enclosure that reduces the exposure of the operator and environment [SOURCE: ISO 5681:2020, 3.2.9.6]
3.3 single transfer operation
actions required to be completed starting from connection of the container to the CTS, completion of the product transfer procedure, measurement of partial transfers where applicable, rinsing of the container and the transfer device, and removal of the container ready for storage or disposal
