Successfully completing the DLMS UA Certification Process means that your device fully conforms with the core DLMS protocol, the globally accepted standard language that ensures interoperability, efficiency and security.  All DLMS UA Certified Products can bear the Certification mark.

The first step in obtaining the DLMS UA Certification is to become a member of the DLMS UA. Only “Members in Good Standing” can complete the Qualification Process. Find out more about DLMS UA membership here.

Members must use a DLMS UA Test Tool (TT) for the Certification of Compliance process. Members should first choose the type of test tool to use – Compliance Test Tool (CTT) or Development Test Tool (DTT). 

Once the Member has determined the type of test tool required, they can then choose to buy a Software-as-a-Service license (annual subscription), a perpetual license (a one-off fee) or sub-license the TT from an existing DLMS UA Member in Good Standing to whom tests have been subcontracted. Click here for details on how to purchase or download the tool and see the pricing and licensing conditions. 

While Members must purchase or license the DLMS Test Tool for the Certification of Compliance, to achieve the Certification of Compatibility, tests need to be performed by a DLMS UA Accredited Test Laboratory. Please refer to the Compatibility Certification process below.

Members are required to test products against the communication protocol that is to be supported by the implemented DLMS Communication profile to ensure that the product under certification is compliant in its declared communication environment. 

Depending on the wireless technology (transport layer) and network layer protocol deployed within the device, the DLMS UA provides members with a test environment for Certification of Compliance that ensures that the product is tested within the declared communication environment. 

Accredited testing devices or "Golden Devices" and appropriate firmware specific to each communication protocol must be used during the Certification Process. A list of accredited testing devices and how to purchase them can be found here.

For Certification of Compliance, once the Test Tool and the Golden Devices have been licensed or purchased, our Test Tool distributor, EuroDCS, will provide the license keys to proceed with the TT installation. The TT is licensed with full documentation and instructions on how to install and run it. Members will provide self-test results via the online platform. 

The Yellow Book is the reference document describing the entire DLMS UA Qualification Process and testing procedures for Certification of Compliance and provides all the necessary information on how to proceed with the DLMS UA Qualification Program application.

Members should then submit the test files via the DLMS UA Qualification Portal to complete the application for Certification of Compliance. 

Once the test files have been submitted, the DLMS UA will issue an invoice and on receipt of its payment, the application and test files will be verified. If successful, the test report will be validated, and the Certificate of Compliance will be issued. The member can then use the DLMS UA Certification trademark on the certified product.

The first step in obtaining the DLMS UA Certificate of Compatibility is to ensure that your device has been certified by the DLMS UA for Compliance. The device must embed the DLMS UA Generic Companion Profile(s) as specified by DLMS UA against which the compatibility should be proven. 

Following the merge of the IDIS Association with the DLMS UA, it is now possible to apply for IDIS Package 3 certification using the online DLMS Qualification Portal as described here. IDIS Package 2 may continue to be certified as described here and will be phased out as communicated here.

Members should decide which Generic Companion Profile(s) that they wish to certify. Multiple Generic Companion Profiles can be implemented in a specific device. However, compatibility testing will be carried out separately for each Generic Companion Profile.

In the case of IDIS Package 3, applicants should request the IDIS Package 3 specification document here. It is essential that the prerequisite Certificate of Compliance is obtained as described in the document. 

Members must apply for compatibility testing via the DLMS Qualification Portal. Only "Members in Good Standing" can complete the Qualification Process. 

Certification of Compatibility tests will be performed by a DLMS UA Accredited Test Laboratory. Members can choose the Accredited Test Laboratory during the Qualification Process. The full list of Accredited Laboratories can be found here. 

Once the application for Certification of Compatibility has been submitted, DLMS UA will issue an invoice for the eligibility verification and issuance of the Certificate. On receipt of its payment, DLMS UA will trigger the Accredited Test Laboratory to begin the testing process. The Accredited Test Laboratory will have already queued the certification application upon submission. The costs associated with the work to be carried out by the Accredited Test Laboratory will be charged directly by the Accredited Test Laboratory to the Applicant.

For IDIS Package 3 Certification, the application for compatibility testing shall only be used if the applicant has obtained a Certificate of Compliance. If this has not been done, then the applicant can apply for "Compliance and Compatibility Testing" where both processes are carried out by a DLMS UA Accredited Laboratory.

The DLMS UA Accredited Test Laboratory has the capability to conduct Pre-Certification and Certification runs of the Test Tool. The costs associated with these tests are published in the DLMS US Internal Regulations (Bylaws).

The Accredited Test Laboratory will perform the necessary compatibility tests and submit the results directly to DLMS.

Members will be notified by the Accredited Laboratory of the status of the testing.  The Accredited Laboratory will submit all the test files to DLMS UA. 

Once the test files have been submitted, the DLMS UA Accredited Test Laboratory will issue a final invoice for the Compatibility testing service.  On receipt of its payment, the test report will be verified by DLMS UA, and the Certificate of Compatibility will be issued. The member can then use the DLMS UA Compatibility Certification trademark on the certified product. Guidelines on how to use the DLMS UA Compatibility Certification trademark are available here.

Applicants that have applied successfully for the IDIS Package 3 Certification can now apply the IDIS logo to their product.
