Gaseous hydrogen — Fuelling protocols for hydrogen-fuelled vehicles — Part 6: Part 6: Conformance test for communication requirements between the vehicle and dispenser control systems

Scope

This document specifies conformance tests for a system under test (SUT) implementing hydrogen vehicle
and hydrogen dispenser according to the generic fuelling communication requirements defined in ISO 19885
2 and the fueling-protocol specific communication requirements defined in ISO 19885-3.
The test system will comprise:
- a hydrogen vehicle tester to verify the communication behaviour of a hydrogen vehicle SUT; - a hydrogen dispenser tester to verify the communication behaviour of a hydrogen dispenser SUT; - a public key infrastructure (PKI) and other secondary actors to verify the security behaviour of a hydrogen
vehicle SUT and a hydrogen dispenser SUT; and - a fueling control system, implementing a fueling protocol, to verify the communication behaviour of a
hydrogen vehicle SUT and a hydrogen dispenser SUT under the control of a fueling protocol
This document specifies test cases for the requirements defined in ISO 19885-2 and the fueling-protocol
specific communication protocol requirements defined in ISO 19885-3, covering the following aspects: - use cases other than those performed by physical or data-link layer of fueling communication or pairing
communication; - fueling-protocol-specific requirements of each fueling protocol; and - interaction of the communication module with underlying fueling system or fueling protocol
The test cases will focus on black-box testing of the communication module of a hydrogen vehicle or
dispenser, while relevant secondary actors, such as PKI or fuelling system, are under the control of the test
system to ensure reproduceable test results.
