I don't think the Openreach network operates outside the UK

.
I don't accept your redefinition of "terminal" as being in common usage for modem/routers. I'm be pretty certain it isn't a usage that carries legal weight.
With regard to SIN 498, Openreach only define the requirements of CPs' filters and
modems to be attached to the network.
The CP provided modem and filtering devices must meet the requirements of this specification in order to provide reliable operation and to avoid harm to other VDSL2 lines sharing the same cable binder. Openreach reserves the right to withhold or limit service where potential violation of the Access Network Frequency Plan (ANFP)[9] or impact to another customers� service is detected.
They do provide conformance testing and advice for CPs, but nowhere in SIN 498 am I aware of any current ban. Nor of any
requirement for certification by Openreach.
With the initial introduction of ADSL and subsequently FTTC there were periods when only Openreach or its contractors could connect anything to the network. There is no EU law against that. it is perfectly normal
for a company providing infrastructure services to specify what its customers may attach to that service. When Openreach removed that requirement, they obviously needed to specify the requirements of their service.
As for BABT, you seem to be unaware of the following:
- BABT is wholly owned by T�V S�D Product Service, Germany's leading testing and certification body;
- BABT is a Notified Body for the following European Directives: 98/13/EC TTE & SESE Directive (now superseded by the R&TTE Directive); 89/336/EEC EMC Directive; 73/23/EEC Low Voltage Directive; 1999/5/EC R&TTE Directive. BABT is a Competent Body for the following Directives: 89/336/EEC EMC Directive.
I suggest the
absence of such green labels, if you are correct, is nothing to do with SIN 498, or Openreach at all.
