Certification introduction

In order to establish the KNX Trademark as a token for quality and interoperability of home and building system engineering products (based on the KNX standard), KNX Association runs its certification scheme for products.

Requirements

If you, as a KNX member wish to label your KNX product with the KNX trademark, you need to prove compliance to the following requirements:

• Quality system according to ISO 9001:
  • No need to be ISO 9001 certified if you are only planning to sell OEM products
• EN IEC 63044-x standard (covering such aspects as EMC, electrical safety, environmental conditions). Compliance can be shown to KNX Association by the submission of a CE- declaration.
• Volume 3 and Volume 6 of the KNX Specifications, the former being a toolbox of the KNX protocol features, the latter listing the allowed profiles of the KNX stack based on the toolbox as mentioned before.
• KNX Interworking requirements as regards standardised data types and (optionally) agreed functional blocks.

Procedure

For registration (entry of the product data in the central database of the ETS software tool for project design and commissioning) and certification, the applicant will have to contact KNX Association’s Certification Department.   

In order to allow a speedy market entrance, products can already be branded with the KNX trademark right after Registration. After that, the KNX manufacturer has a maximum of 6 months to complete the testing of his product.   

For the software testing, the manufacturer has the choice of a number of KNX accredited test labs, authorised to carry out third party KNX system and interworking tests. For hardware testing, the applicant either has the various testing facilities at his premises or takes recourse to a test lab of his choice.   

During software testing, emphasis is put on testing of not certified parts only. As an example, a product based on an already tested KNX bus access unit (of which compliance to the system specifications has already been proven) must merely be submitted to the interworking tests.   

A uniform test tool (EITT software) ensures that the manufacturer is able to prepare much of the software test campaign at his premises and provide this preparation as input for third party testing.   

As soon as our certification department has received all test reports as regards system and interworking conformity together with the CE declaration for the hardware, a KNX certificate will be issued out to the KNX manufacturer, confirming the use of the KNX trademark on the tested product.
