After entering the 21st century, the concept of consumers is constantly changing. Price is not the only consideration. A certain brand recognition is needed to ensure confidence in the use of safety. Products with reliable UL certification marks represent a series of in-depth evaluations by UL professional engineers, which can bring consumer confidence.
Connector for UL certification test standard: UL1977
the main test items and objectives of connector UL certification are as follows:
1. Aging test (Mold Stress Relief Test) : Confirm whether the insulation material of the connector meets its preset use conditions, such as operating temperature (operating temperature) and temperature rise during normal use..
2. Temperature rise test (Temperature Test): Confirm the rated specifications of the connector, such as the rated current value (rated current), the applicable wire size (rated wire size), the number of poles (pole)... Whether it is consistent with its plastic temperature level under normal use conditions.
3. Withstand voltage test (Dielectric Voltage-Withstand Test) : Confirm whether the structure and insulation material of the connector are consistent with the rated voltage (rated voltage) of the connector.
4. Wire tension test (Conductor Secureness Test) : Confirm whether the connection between the crimp terminal (crimping terminal) of the connector and the wire (conductor) is stable.
