Use of certification logo with products

We are a online shop and want to use certificates to increase our trust level.
Therefore, I want to know, if it is allowed to use regular ISO signs you can find when you google for and just place the certificates as PDF's behind the?”

Answer:

ISO 9001 certification is not about the products but about the quality management system. According to most of the rules about the use of certification logos, they should not be used in contact with products. Nevertheless, I see, for example, buses with certification logos applied.

I would be comfortable with the use of the certification logo with the name of the manufacturer, side by side with the product.
