The definition in Article 2 (13) also covers other permanent joints such as e.g. those produced by brazing, braze welding, expansion, gluing, frettage and riveting.
For that reason, the requirements of Annex I Section 3.1.2 and 3.1.3 apply also for these types of joints.
Note:
Removable expansion devices (e.g. expansion plug for sealing exchanger tubes) do not require destructive methods to be disconnected and therefore are not permanent joints.
