Alice, I have found that inspectors have allowed a manufacturer to claim more stringent or limited ratings than what is in the UL report.
In some products that are rated at 120v from line-to-neutral, but are truly 3-phase products, it has been customary that you can denote the operating voltage as 120/208 vac, 3-phase, 4W+G. However, you need to check and make sure the voltage and number of phases are correctly detailed in the report. If a product has been evaluated by a safety agency, I do not see why you would not want to include the mark. However, there are cases on UL products that the mark is not required. One example is that the device is too small to bare the mark. You need to check the marking requirements for that product. When UL performs an IPI, the inspector needs to bring the report with them. This should be complete and include all section, except for the test record. I have often found this process strange as we do an inspection on the product to the report prior to manufacturing to ensure that our report and product structures are in agreement. When the UL inspector brings the report, it is very difficult to perform this check. You can request a preliminary copy of the report from your UL engineer. While it is unofficial, it will help in the process. As for reports, I am not sure if there is a generally accepted method for constructing them within the various agencies. Every time I get a report from a different engineer regardless of agency, they have differences. Good luck.

Scenario : Component A with rating mentioned in the UL's product report as 90-135/180-265 Vac, however in the phyical unit is written as 115/230 V . Q1 : Is this a non conformity ? Should a VN be raised ? Scenario :In the report, it mentioned the marking on the label as 120-127V , however in the actual label on the unit it is written as 120-127V/220-240V. Q2. Is this a non conformity ? Should a VN be raised ? Scenario : In the report, it mentioned component B carries many safety agency certification, however i the actual physical unit, it only containes one or two safety agency logos. Q3. Is this a non conformity ? Should a VN be raised ? Q4. When an IPI ( Initial product inspection ) is carried out, should the UL's product report been approved by the UL ? Q5. Should the report used during IPI is a detailed report with Sec general and condition of testing been included ? Q6. Can anyone share with me the correct ways the product report/FUS procedure for a product should be written so that we are not caught up with it, particularly on the rating,model and safety agency certification requirement for the product ? I am looking forwards to hearing a reply from you.
