讨论:UL测试设备要求
UL的相关标准中都有对UL产品,如电源线等,的特性做测试,其相关的测试所需要的仪器要求,在标准中,提到的就很是简单。为了能使生产商在产品自测时保证与UL测试的方法接近,减少测试误差。其使用的测试设备就很是重要。故请教各大虾是否有相关的UL对产品测试设备的要求(清单,规格要求)信息等资料。可以拿出来,大家共同讨论。以期产品能更有保障的通过UL测试。 Pls focus on:1. All test equipments must be calibrated at regulated intervals,if applicable;
2. And all the calibration can be traced to CNAS level. At this time, some guys may say it's so easy, just send this kind of equipments to a third calibration party, then that's OK. But I still wanna say, first, not all the third calibration parties have the CNAS authorities, secondly, even if they have the CNAS authorities, but that does not mean, all their businesses are covered by the CNAS, so pls check it before you send the equipments to do the calibration work.
For calibration, pls refer to the attachment...... 謝謝LS參與,就設備量具校檢方面,附件資料很有參考價值。但就測試設備規格要求方面呢?
再謝了! Normally, UL has no requirements about the specification of the test equipments if the equipments can finish the required tests, that's ok, so what you really need to prepare is that you must know the test requirements and how to do the tests, study the related standards, or it's much better to know why the tests are needed and what's the objects of the tests....

Yes, UL1581 is also for Wire and cable, and every test equipment has its own specification, such as the spark tests on the production line for the wire and cable, there are some requirements , such as the diameter of the beads and the distance between the beads, but normally, most of the spark tester have the similar specification, so as a certification and testing engineer, what you should focus on is the corresponding product standards, you must know the test requirements and some other things...
@@@aji:
pls see attachment for UL817 FUII, in this file , there is some description about the tests... 多谢参与,谢谢! 记得UL电线认证UL有仪器方面的规定文件。 UL细则每个UL工厂均,请认真看,期待有一天可以看到中文的审厂细则
