1. Tests in the scope of product’s certification

To obtain the certification of Solar Thermal Collectors it is necessary to contact a certification body. Type tests are performed in the beginning of the certification process. It is up to the certification body to select, in the factory, the samples for tests that will be sent to the Laboratory that will perform the type tests. For this procedure, the contacts should be established with the certification body that requests the Laboratory to perform the tests. The certification bodies available in the frame of the European Scheme Certification are available on the website Solar Keymark.

In Portugal the certification body is CERTIF:

2. Tests out of the scope of product’s certification

If the product certification is not the option needed but only collector testing, the contact for test request is established directly with the Laboratory.

To request a test it is necessary 

The request is formalized on the date that the Laboratory receives these documents.
