EU Pressure Equipment Directive (PED)

97/23/EC Official Reference

Date of Enforcement

Optional: 29/11/1999
Mandatory: 29/05/2002

Scope

The Directive applies to the design and manufacture (but NOT operation)of both individual items and assemblies of pressure equipment with a maximum allowable pressure greater than 0.5 bar (gauge).
Any product that contains such a pressure falls within the scope.
In addition, Safety Accessories that may not contain the pressure fall within the scope. An example of a safety accessory is a pressure or temperature switch if it is being used as a safety control in pressure equipment.

Exclusions

There are a large number of exclusions which mostly refer to equipment already regulated in other directives such as pressured containers used to transport fluids.

Products are either in scope and must be CE marked or they are outside the scope and may not be CE marked. There is no choice on this issue!

As there is no legal means whereby an excluded product can be CE marked, you can be assured that HPiVS will confirm, on application, if your product is excluded.

Standards

Conformity with harmonised standards “guarantees” conformity with the directive. Their application, however, is not mandatory. If harmonised standards are not suited to a specific product, any alternative standard or solution may be applied if it ensures equivalent safety. It can be difficult to demonstrate equivalent safety and harmonised standards should be applied wherever possible. HPiVS can advise on alternative methods.The detailed technical characteristics of the design, materials, production and testing are not laid down in the Directive but in harmonised standards.

 

Conformity Assessment Procedures

The Directive has a wide range of Conformity Assessment Modules that define what documentation needs to be compiled and to what extent a Notified Body should be involved. The choice of modules is limited depending upon the risk of the product. For PED, the risk of the product is based upon three factors:

  1. the state of the contained fluid;
  2. the stored energy;
  3. the hazards associated with the fluid.

 

Brazing Procedure Specifications – Scope

The preliminary brazing procedures specification is a test piece not yet approved, but believed to meet the requirements as specified in BS EN 13134.
BS EN 13134 states that one of the methods used to get approval of a pBPS to a BPS is by carrying out appropriate brazing procedure tests for approval by an examiner or examining body.
In the case of the flame torch brazing, the brazer who undertakes the brazing procedure test satisfactorily in accordance with standard is thereby approved by BS EN 13585.

The BS EN 13585brazing approval sets down standards for brazing procedure specifications used in production and manual flame brazing for competent brazers.
Because of the wide range of applications the standard does not specify detailed acceptance criteria as these are product specific and have in each case to be agreed prior to contract. List of items (conditions) to be agreed in each contract are listed (documented) in clause four of EN 13585.
The certificate of approval testing is issued under the sole responsibility of the examiner or the examining body. The test pieces can be tested under the following:
EN 12797 destructive examinations of brazed joints.
EN 12799 non-destructive testing of brazed joints.
EN 13134 brazing procedure approval.
Examiner or examining body may be a notified body OR recognised third party.

Under the guidelines of EN 13134 each candidate is allowed to produce three test pieces as per pBPS carry out a visual examinations before deciding which piece will be offered up to the examiner or examining body for their visual examination and additional appropriate tests. The basic requirements of the exam are to examine the soundness of the brazed assembly.
