two. Purpose: To verify that the product meets the reliability requirements and to use customer standards when the customer has standards
three. definition:
a) If the temperature and humidity used in the standard are not specified, the default is ±2°C and +2%/-3%RH, respectively.
four. standard
4. Test:
1) Applicable products: The systems and products represented by Shenzhen Delongtai Technology Co., Ltd. are rigorously tested by recognized professional testing organizations, and the management and production processes conform to ISO 9001 and ISO 14001 system certifications. Strict quality control ensures the reliability and safety of systems and products, meets the different needs of customers in different regions of the world, and provides users with high-quality, high-reliability fluid monitoring and control and electrical automation products.
2) Test conditions:
* One piece thin valve plate
* Valve uses multiple connection standards
*Valve seat integrated die pressure
* Connection: clip, ear
3) Test method:
a) Rated input voltage and load of the product, work in the test box at 50°C (60°C) for 2.5h (4.5h), then power off for 0.5h, as a period
b) Check sample output voltage and current per duty cycle
4) Judgment criteria:
a) Definition of failure: It is verified from the user's point of view whether the function of the product is normal, that is, it is defined as failure when the output voltage of the product exceeds Spec.
b) Failure is defined as failure if the product fails to recover at normal temperature during the test
