I don’t know what instruction your CE is made according to. The PED instruction is an instruction in CE certification. Generally speaking, the PED certificate is the CE certificate, but the CE certificate is not necessarily the PED instruction certificate. , this is a coverage issue.
Too many people only know about CE certification for ordinary electrical appliances. When it comes to CE, it means LVD, EMC and so on. PED is actually an instruction for CE certification of pressure vessels. It is parallel to LVD and EMC, but The requirements are different. Category 2 and above must be certified by NB organizations, and PED is the CE certificate.
