What are the certification bodies of ISO4500 1?

At present, there are some well-known ISO4500 1 certification bodies, including SGS, TUV Rheinland, DEKRA, DNV GL and Intertek Tian Xiang Group. However, it should be noted that this is an incomplete list, because with the passage of time and the development of the market, there will be more and more certification bodies. I suggest you consider it carefully when choosing. At the same time, we also remind everyone that we must choose an accredited and qualified certification body to avoid being deceived by false or invalid certificates.
