Answer

Vessels referred to in
Article 4 (volume less
than or equal to 0,1 litre)
Table in
Annex II
Category
(Volume less than or equal to 0,1 litre)
1.(a)(i) first indent 1If PS ≤ 200 bar, then Article 4.3
applies
otherwise see point 3 below
1.(a)(i) second indent 2If PS ≤ 1000 bar, then Article 4.3
applies
otherwise see point 3 below
1.(a)(ii) first indent 3If PS ≤ 500 bar, then Article 4.3
applies
otherwise see point 3 below
1.(a)(ii) second indent 4If PS ≤ 1000 bar, then Article 4.3
applies
otherwise see point 3 below

Reason:

  1. The conformity assessment categories for vessels with a volume less than or equal to 0,1 litre cannot be determined from Tables 1, 2, 3 and 4 because the Tables are not specified for volumes less than 0,1 litre.
    However, Article 4 paragraph 1 together with Article 4 paragraph 3 can be used to determine which vessels must satisfy the essential safety requirements and those that must be designed and manufactured according to the Sound Engineering Practice (SEP) of a Member State.
  2. If a vessel has a volume less than or equal to 0,1 litre, and a value of PS above the limits defined in Article 4 paragraph 1, then the vessels must satisfy the essential safety requirements of Annex I.
  3. In the absence of specific information in the Tables of Annex II for the conformity assessment of vessels described in point 2 above, the manufacturer may choose any module‚ or single combination of modules, set out in section 1 of Annex II.
