1.0 INTRODUCTION

The European Pressure Equipment Directive (PED) (97/23/EC – May 97) is currently implemented inthe UK as the Pressure Equipment Regulations: 1999 (SI 1999 No. 2001). The Directive came into forceon 29 November 1999.

The Directive has wide ranging implications for the Oil, Gas and Petrochemical industry and the intent ofthis document is to provide guidance on those implications for PSN.

2.0 SCOPE

PED applies to the design, manufacture and conformity assessment of all items of pressure equipmentand assemblies with a maximum allowable pressure greater than 0.5 bar above normal atmospheric

pressure (gauge pressure).

Under the Regulations, pressure equipment and assemblies above specified pressure/volumethresholds must:

• be safe

• meet essential safety requirements covering design, manufacture & testing

• satisfy appropriate conformity assessment procedures; and

• carry the CE marking and other information

3.0 DEFINITIONS

The Regulations define:

Pressure Equipment as vessels, piping, safety accessories and pressure accessories;

Where applicable, pressure equipment includes elements attached to pressurised parts such asflanges, nozzles, couplings, supports, lifting lugs etc.

Vessel as a housing built to contain fluids under pressure;

A vessel includes its direct attachments up to the coupling point connecting it to other equipment. A

vessel may be composed of more than one chamber.

Piping as piping components intended for the transport of fluids when connected together forintegration into a pressure system:

Piping includes a pipe or system of pipes, tubing, fittings, expansion joints, hoses, or other pressurebearing components as appropriate. Heat exchangers consisting of pipes for the purpose of heating orcooling of air shall be considered as piping.




Page:4 of 55


Safety Accessories as devices designed to protect pressure equipment against the allowable limitsbeing exceeded.

Such devices include those for direct pressure limitation, such as safety valves and bursting discs etc,

and limiting devices which either activate the means for correction, or provide for shutdown or shutdownand lockout, such as pressure switches or temperature switches etc.

Pressure Accessories as devices with an operational function and having pressure bearing housings.

Assembl ies as several pieces of pressure equipment assembled to constitute an integrated andfunctional whole.

NOTE: The Regulations do not apply to the assembly of pressure equipment on site(s) and under theresponsibility of the user, as in the case of industrial installations. In such cases the “ in-use “regulations will cover the assembly of pressure equipment on site.

Responsible Person: “The manufacturer or his authorised representative established within thecommunity”.

The responsible person may arrange for any, or all, of the activities involved in the design andmanufacture of an item of pressure equipment to be carried out by others. Such activities include:

• Ensuring compliance with essential safety requirements

Technical requirements are more fully explained in Article 3 of the Directive.

5.3 CLASSIFICATION OF PRESSURE EQUIPMENT

In order to know how the Regulations will apply to specific items of pressure equipment, themanufacturer will need to classify the equipment into one of five conformity assessment categories.

These can be found in the conformity assessment tables in Annex II of the Directive.

For Pressure Accessories the designer/manufacturer will need to know:

• The state of the intended fluid contents – gas or liquid

•

The classification of the intended fluid contents – Group 1 or 2• The maximum allowable pressure

• The volume in litres or the nominal size (DN) as appropriate

NOTE: Group 1 fluids are classified as dangerous substances and are one or more of the following:

• Explosive

• Extremely flammable

• Highly flammable

• Flammable (where the maximum allowable temperature is above flashpoint)

• Very toxic

•

Toxic• Oxidising

Group 2 comprises all other fluids including steam.




Page:9 of 55


5.4 CONFORMITY ASSESSMENT

Before placing pressure equipment or assemblies on the market, the manufacturer shall subject eachitem of equipment to one of the conformity assessment procedures described in Annex III of the

Directive.

In order to demonstrate that the essential safety requirements are satisfied, equipment will be subject toconformity assessment.

The manufacturer has a choice of attestation modules available to demonstrate compliance to theDirective, which includes:

• Self certification

• Third party involvement by a notified body

• Quality assurance assessment by a notified body

• Combination of the above

The conformity assessment procedures to be applied to an item of equipment or assembly with a viewto affixing the CE marking are determined by the category of the equipment (see Annex II of theDirective).

The higher the category and therefore the hazard, the more demanding the requirements.

Annex II of the Directive gives nine conformity assessment tables which are used to determine thecategory for each item of pressure equipment.

5.5 CONFORMITY ASSESSMENT PROCEDURES

The conformity assessment modules are laid down for each category in which the pressure equipmentis classified and should be used by package engineers to determine the outline quality controls for theirparticular pressure equipment package.

The headings for the various modules are given below and full details can be found in Annex III of theDirective.

• Module A Internal production control

• Module A1 Internal production control with monitoring of final assessment

• Module B EC type – examination

• Module B1 EC design – examination

•

Module C1 Monitoring of final assessment

• Module D Quality assurance for production, final inspection and testing

• Module D1 Quality assurance for production, final inspection and testing

• Module E Quality assurance for final inspection and testing

• Module E1 Quality assurance for final inspection and testing

• Module F Product verification

• Module G Unit verification

• Module H Full quality assurance

• Module H1 Full quality assurance with design examination and monitoring of the final assessment

Where PSN is responsible for manufacture then this document together with existing quality assurance

procedures allow PSN to operate under module H or H1 as appropriate.• Module H covers pressure equipment or assemblies up to Category III.

• Module H1 covers is applicable to Category IV pressure equipment or assemblies




Page:10 of 55


5.6 ESSENTIAL SAFETY REQUIREMENTS

Equipment classified in Categories I to IV will be required to meet requirements for design, manufacture,

testing, marking, labelling, instructions and materials which are considered essential for safety reasons.This also includes safety accessories and pressure accessories intended for equipment classified in theabove categories.

The essential safety requirements are mandatory and must be addressed by the manufacturer.However they only apply if the corresponding hazard exists for the pressure equipment in questionwhen it is used under conditions which are reasonably foreseeable by the manufacturer.

The essential safety requirements are to be interpreted, and applied, in such a way as to take accountof state of the art and current practice at the time of design and manufacture as well as of technical andeconomic considerations which are consistent with a high degree of health and safety protection.

The manufacturer is under an obligation to analyse the hazards in order to identify those which apply tohis equipment on account of pressure. Design and construction must take this hazard analysis intoaccount.

The essential safety requirements, as they apply to PSN, are fully detailed in the table (Attachment 03).

5.7 TECHNICAL DOCUMENTATION

The manufacturer is required to retain technical documentation which must contain all relevantinformation and data about the means they have used to ensure that their pressure equipment and/orassemblies comply with the requirements of the Directive.

This technical documentation should represent part of the final document review prior to the issue of aninspection release note. Details of technical documentation requirements are laid out in Attachment 07.The technical documentation shall enable the conformity of the pressure equipment to be assessedagainst the requirements of the Directive, and would typically include:

• Name and address of the manufacturer

• Name and address of the manufacturers representative in the community

• Identification, and general description of the equipment

• Conceptual design, manufacturing drawings etc

• Descriptions and explanations necessary for the understanding of the drawings
