No.
Article 4 paragraph 3 explicitly prohibits CE marking of SEP pressure equipment.
Article 13 paragraph deals with the classification of pressure equipment referred to in Article 4 paragraph 1 (not paragraph 3) and Article 14 sets out how the conformity assessment procedures should be determined for such equipment. Therefore Article 14 paragraph 3 does not apply to SEP pressure equipment and it does not provide any derogation to the provision in Article 4 paragraph 3 that prohibits CE marking of SEP pressure equipment.
