Electronic appliances testing process

1、Send sample

2、Free initial inspection

3、Quote

4、Both sides determine, sign a confidentiality agreement, start the experiment

5、7-10 working days to complete the experiment

6、Issue the test report, the later service.

Testing program development and quotation

Customer service advisors according to your testing needs, study to determine the testing program and quotation, the quotation will be sent to you and communicate in detail the content of the testing program, you determine the testing quotation and fill out the commissioning test sheet.

Electronic appliances testing sample delivery requirements

Sample preparation as follows:

1. Finished product testing

ROHS: at least 1 set of finished products, after splitting the amount of samples of each component is not enough to contact the customer service consultant to make up samples.

REACH: at least 2 sets of finished products.

Raw material or component testing

(1) Single test: 10-20g for solids, 20-30mL for liquids, and metal plating surface area >200cm2;

(2) to carry out more than 3 tests: solids > 30g, liquid > 50mL, metal plating surface area > 500cm2;

(3) the weight of organic coating (such as paint) parts can not meet the requirements of the amount of samples sent, can provide coating materials;
