Q: How do I know if my
product falls within the
parameters of the Pressure
Equipment Directive
(97/23/EC)?
A: The PED applies to pressure
equipment (vessels, piping, pressure
accessories), safety accessories or
assemblies with a maximum allowable
pressure (PS) greater than 0.5 Bar (7.25
psi). Manufacturers or assemblers of
pressure equipment above this pressure
must review the requirements of the
directive to determine if their products fall
under the directive. In determining the
category of the product, the fluid and
volume (vessels) or nominal size DN
(piping) must be considered. The fluid (e.g.
gases, liquids, vapors) in combination with
the pressure will determine the applicable
category. Depending on the product of the
PS x Volume/DN, and the fluid, a product

TUV Rheinland of North America, Inc. invites you to ask the experts. Your questions can
pertain to anything that you want to know about product testing and certification services
regarding Automotive, EMC, Ergonomics, Field Evaluation, Industrial Machinery,
Management Systems, Medical, Pressure Equipment, Product Safety and Telecom. Please
check back each issue to find out what questions have been answered.
Please submit questions to tconroy@us.tuv.com and write in the subject line “Ask the Experts.”

Category I, II, III or IV. The lower the
category, the less mandated involvement
by a Notified Body.

Q: How do I pick the proper
PED (97/23/EC) Conformity
Assessment Module for my
product?
A: The first step to evaluating the best
choice of modules is to properly categorize
the product. Under the PED, products and
systems are reviewed, approved and/or
monitored on a regular basis. Module
choice is based on category, and the
choice of modules can be impacted by
several variables: 1) Category; 2)
Production Schedule (e.g. one-of-a-kind
vs. serial); and 3) Quality System.

Q: Can I use the ASME Code
to satisfy the Essential
Safety Requirements (ESR)
of the Pressure Equipment
Directive (PED)?
A: Yes. Manufacturers that use the ASME
Code have to prove that the pressure
equipment complies with the Essential
Safety Requirements (ESR). Additional
requirements to ensure compliance with
PED also have to be met:
Proof Test – A basic of 1.43 times its
Maximum Allowable Working Pressure
has to be met.
Stability – The respective loads for wind,
snow, earthquake, etc., as well as special
building regulations have to be considered.
Operating Instructions – Operating
instructions should be available at the time
of the design approval and must be
evaluated by the Notified Body.
Hazard Analysis – The manufacturer is
obliged to accomplish a hazard analysis.
The hazard analysis shall include the
following:
• Identification of hazards due to
pressure
• Elimination or reduction of hazards
• Protection measures
• Means of examination
• Means of draining and venting
• Corrosion or other chemical attack
• Wear
• Assemblies
• Provisions for filling and discharge
• Protection against exceeding the
allowable limits
• Safety accessories
• External fire
