The LES, Solar Energy Laboratory, is an accredited Laboratory by the Portuguese Accreditation Body to perform tests to Solar thermal collectors and Solar thermal systems, according to the European Norms EN ISO 9806 and EN 12976-2. The Laboratory, based on the results of the tests, evaluates the conformity to the requirements of the European Norms EN 12975-1 e EN 12976-1.

The test can be performed out of the scope of certification of solar thermal collectors.

1. Tests in the scope of product’s certification

To obtain the certification of Solar thermal collectors and Solar thermal systems 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 www.solarkeymark.com.

In Portugal the certification body is CERTIF:

To request a test it is necessary

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