Industrial equipment exports to the United States of China's products are increasingly strict requirements, although there are many types of industrial equipment, so UL standards for specific products can not be developed very perfect, but basically to comply with the following standards, Specifically, with the
Construction machinery CE certification institution to understand it!
• UL 50 – Enclosures for Electrical Equipment; Enclosures for electrical equipment; Different shell Types are defined depending on the use environment (e.g. Types 1, 2, 3, 3R, 3S, 4, 4X, 5, 6, 6P, 12, 12K and 13).
• UL 508 – Industrial Control Equipment, which requires most electrical components, including contactors, relays, push-button switches, signal lights, and various ancillary devices; Drive (including inverter, inverter) and dynamic brake module in the standard UL 508C, see below
• UL 508 A – Industrial Control Panels
Industrial control panels
• UL 508C – Construction, performance and marking requirements for Power Conversion Equipment, including drive and dynamic brake modules; SU 2011(Outline) requires that all drive parts should be UL listed or UL approved parts
• NFPA 79 – Industrial Machinery, including the shell structure, grounding, wire color and size, isolation protection circuit, controller and identification requirements, including industrial machinery control cabinet requirements equivalent to UL 508A part 65 to 67
• NFPA 70 – National Electrical Code (NEC) National Electrical Code (NEC); All UL standards above are based on this specification
These are basic requirements, but it also depends on whether the enterprise is for the whole machine or the control part of the application, the focus of the two applications is different, there will be a difference in standards. Our engineers will help enterprises to conduct standard determination, technical training and pre-inspection before the
UL certification engineer inspection, and also help many domestic enterprises to pass UL, CSA certification.
