Whether a quartz watch needs to undergo UL4200 testing depends on its target sales market and the type of battery used. UL4200 is a safety standard developed by UL (Underwriters Laboratories). It is mainly used to evaluate button batteries (especially lithium button batteries) in specific products. Safety in use to reduce the risk of children accidentally ingesting batteries.
1. Understand the UL4200 standard
First of all, you need to understand the UL4200 standard in detail, which is mainly targeted at consumer products containing button batteries or coin batteries, including quartz watches. Its main purpose is to ensure that the safety performance of the batteries of these products is guaranteed under normal use and abuse conditions, and to reduce the risk of children accidentally ingesting the batteries.
2. Determine testing needs
Confirm whether the quartz watch is suitable for the UL4200 standard, and determine the required testing items and requirements. This includes structural requirements, performance testing, battery compartment safety testing and warning label requirements.
3. Select certification agency
Choose a laboratory with UL certification to conduct UL4200 testing. Ensure that the laboratory has ISO 17025 certification to ensure the accuracy and reliability of test results.
4. Prepare information
Prepare the following information for testing:
Detailed technical specifications, design drawings, instructions for use and other related information of the product.
1:1 sample ensures that the sample is consistent with the actual product for accurate testing.
5. Fill in the application form
Download the application form from the laboratory's official website or fill it out offline and stamp it with the official seal. Send the application form to the laboratory so that the laboratory can understand the testing needs and prepare relevant tests.
6. Quotation and payment
Based on the selected services and requirements, the laboratory will issue a quotation. After confirmation by both parties, the customer pays the testing fee.
7. Sample testing
The laboratory tests quartz watch samples according to UL4200 standards, including structural requirements, performance testing, battery compartment safety testing, etc. During the testing process, the laboratory will retain samples for subsequent testing.
8. Report review
After the test is completed, the laboratory will conduct an internal review of the test report to ensure that the report content is accurate.
9. Issue reports
After passing the review, the laboratory will issue a formal UL4200 test report. This report will prove that the quartz watch meets the requirements of the UL4200 standard and can be used for product sales and promotion in the US market.
