Spanish to English Tech/Engineering Transport / Transportation / Shipping Testing

From a text from Spain for translation to British English. Relating to equipping of trains with certain equipment and its testing for putting the new trains into service. There are two parallel documents:

one on "pruebas de tipo en factoria", where the definition of the test protocol aims to ensure that the equipment "cumple con los requisitos del proyecto y está correctamente integrado en la composición de tren"

the other on "pruebas de serie en factoria", where the definition of the test protocol aims to ensure that the equipment "está correctamente instalado en la composición de tren"

I understand these then to mean that the "prueba de tipo" confirms that this type of equipment operates as defined in the project requirements and can be integrated into the train as designed ("type testing"?), while the "prueba de serie" means testing each individual equipment installation to ensure that the individual item of equipment is properly installed and working as expected. Any other viewpoints on these terms?
