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

A member of KNX Association shall prove compliance to the following requirements, if he wishes to label a developed KNX product with the KNX trademark :

• Implementation of a quality system according to ISO 9001
• Requirements of the European standard EN 50090-2-2 (covering such aspects as EMC, electrical safety, environmental conditions, of bus products) and an appropriate product standard. Compliance can be shown to KNX Association by the submission of a CE declaration.
• Requirements of 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 be branded with the KNX trademark after registration. After that, the applicant has a maximum of 6 months to complete the testing of his products.

 

For software testing, the applicant has the choice of a number of KNX accredited test labs, authorised to carry out third party KNX system and interworking testing. 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 uncertified 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 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 certificate is issued confirming the use of the trademark on the tested product.

 

 

For a more detailed explanation on the KNX certification process for products, please refer to the relevant presentations as given at the most recent KNX Technology Tutorial workshop of 2004.
