Deliverable 5.3 Validation/Test Procedures of Wagon and Locomotive DAC up to Level 5

D5.3 shall define tests for wagon- and hybrid couplers needed to achieve TRL8 of the described products. The content and structure of tests is made to validate compliance to requirements in D5.2. The methodology involves 3 different types of tests:

• Type tests shall be used to validate if the products are meeting the overall strength requirements.
• Functional tests on test bench level shall validate general functionality of the products and first level of interoperability.
• Train lab test shall be performed to confirm functionality, interoperability and safety on train/wagon level.

Specific tests demanded in relation to train functions and power and data functionality are part of documents D 5.1 and D 5.4.

The reliability aspect can only be tested on a test bench level and thus showing the fatigue behavior of the products. A full range of product related experience and reliability as well as some maintenance aspects can only be gathered in specific field tests and is not a target of this document.

Operation of demo trains shall be used to collect field data in regards of reliability. A list of reliability assessment criteria shall be prepared before testing. A theoretical assessment based to requirements shall lead to adaptions if feasible.

Test facilities, capabilities and or available rolling test might not be available to perform all specified test. In case an expert team shall define how the required performance can be tested according to an equal level to achieve full TRL target.

Based on the need of specific and detailed test specifications acceptance criteria (i.e. number of repeat cycles, …) are clearly defined in these documents.
