Choose the lab you want to work with and submit your product for testing. After testing is completed, the lab will send you a notice on whether the product complied. If the product complies, you can create your certificate directly on the Zhaga website. The product will also be listed on Zhaga’s Product Database.


If a product does not comply, take the necessary steps to update the product and then resubmit it for testing.



Details on the certification process can be found in the individual book pages. Start with the Book Overview and then move to the specific book.

When submitting your product for testing, you might also need to hand over Letters of Confirmation (LoC). See details in the individual book page.
