GUIDE FOR ASME STAMP HOLDERS
Use of ASME Section VIII, Division 1 to Meet the
EC Pressure Equipment Directive (97/23/EC)
FOREWORD
This Guide is a comprehensive review of the Pressure Equipment Directive (PED) and
ASME Section VIII, Division 1.
ASME has received requests from all over the world to provide guidance to manufacturers
who have been or will be impacted by the European PED. This document provides that
guidance.
Manufacturers of Section VI11 pressure vessels will find this document to be a useful
tool when working with a notified body toward compliance with the PED and applying
the CE mark to their products.
This document begins with an explanation of the European New Approach, and continues
with the goals of the PED and a description of its scope of coverage. Then, the document
offers an in-depth analysis of the PED concept of hazard categories and the various
combinations of conformity assessment modules that can be used for each hazard category.
Each of the PED Essential Safety Requirements are then covered, including materials, use
of Notified Bodies, and requirements for CE marking.
The reader is next presented with a detailed comparison of the PED with Section VIII,
Division 1, followed by a modified version of Annex Z for Section VIII, Division 1. This
Annex Z provides instructions regarding what additional tasks must be completed to meet
the administrative requirements of the PED.
As an added bonus, a list of interpretations developed in France is provided, with
information on how to obtain copies of each.
Should help you a lot.
