SCHEDULE 3 (Annex II to the Pressure Equipment Directive)CONFORMITY ASSESSMENT TABLES

1.  The references in the tables to categories of modules are the following:

I

=

Module A

II

=

Modules A1, D1, E1

III

=

Modules B1+D, B1+F, B+E, B+C1, H

IV

=

Modules B+D, B+F, G, H1

2.  The safety accessories defined in Article 1, Section 2.1.3, and referred to in Article 3, Section 1.4, are classified in category IV. However, by way of exception, safety accessories manufactured for specific equipment may be classified in the same category as the equipment they protect.

3.  The pressure accessories defined in Article 1, Section 2.1.4, and referred to in Article 3, Section 1.4, are classified on the basis of:

• their maximum allowable pressure PS, and

• their volume V or their nominal size DN, as appropriate, and

• the group of fluids for which they are intended,

• and the appropriate table for vessels or piping is to be used to determine the conformity assessment category.

• Where both the volume and the nominal size are considered appropriate in the second indent, the pressure accessory must be classified in the highest category.

4.  The demarcation lines in the following conformity assessment tables indicate the upper limit for each category.
