6.1 General
The execution of a CABCA cycle involves several distinct phases, driven by specific triggers and resulting in a documented conformity status. The overall process flow, including variations based on the assessment mode, is visualised in Figure 6.1‑1. ETSI ETSI TS 104 008 V1.1.1 (2026-01) 19 An assessment cycle can be co...

700e2f9cc025d565da15725694fe1bf2
104 008
6.2.1 Self-Assessment Path
In the Self-Assessment Path, the AI system provider acts as the auditing party to internally validate conformity. The primary input for this path shall be the Assessment Report. As shown in Figure 6.2-1, the AI system provider (acting as the auditing party) shall directly proceed to "Provider Reviews Results/Report". B...

104 008
6.2.2 Third-Party Assessment Path
The Third-Party Assessment Path involves an independent external body and uses the Assessment Report as its primary input. The process, shown in Figure 6.2-2, begins when the AI system provider shall execute the step "Provider Makes Results/Report Available to Third-Party". The external body then shall proceed to "Thir...

As described in the ETSI TS 104 153-2 [3], the test tool is required to emulate both an IPv4 node and an IPv6 node. It must handle traffic conversion in two directions: IPv4-to-IPv6 (T46) and IPv6-to-IPv4 (T64). For that reason, the test case preambles and postambles are named as follows: IUT is an XLAT (example TC_XLA...
