IECQ Frequently Asked Questions and Answers
1. Some companies believe that as long as a test report shows the content of heavy metals such as lead, cadmium, mercury, and hexafluoride, it can be used to determine the RoHS compliance of materials. For example, some companies use test reports collected on the European EN71-3 toy safety standard to determine RoHS compliance. Is it acceptable? Answer: Unacceptable. The regulations of EN71-3-9 are the "dissolution amount" under a certain environment, while RoHS is the "content" of the material. The sample preparation methods for the two tests are different, and the measured results may be very different. The test data cannot be replaced by each other. . 2. The purchased parts contain a variety of colors, but the test report only shows the harmful substance content of one of the colors. Can such a report be used to determine the RoHS compliance of materials? Answer: No. 3. When there is only one test result for a single homogeneous material in a component, can it be used to determine the RoHS compliance of the entire component? Answer: No. Only one product can be proven to be compliant. 4. As there may be contaminated processes in the production process, switching cleaning methods are usually adopted to prevent cross-contamination, but its effect is difficult to prove. What are some reference suggestions (or experiences)? Answer: The cleaning and confirmation methods will be determined based on the risk of contamination. Evidence of cleaning capabilities can be considered from several aspects: 5. For factories that have completed the switch to RoHS, all products need to meet RoHS requirements. Is labeling a key control item at this time? Answer: 6. How to confirm the materials provided by suppliers?
