What QC testing is required for Micro Duct Connector out of the factory

Figure-1 Micro Duct and Micro Duct Connector

The Micro Duct Connector were developed to connect microducts with each other.Our system enables an easy, fast connection and disconnection of the microduct. The connectors’ robust construction resistance to high pressure forces,allowing them to be used in direct buried (DB) applications. The transparent body enables easy visual inspection of the cable with in the connector.

There will be a total of 11 testing items, please see the table below for details.Sample specifications: 16/12mm Micro Duct Straight Connector
