EHP001 certification guideline

Download guidelines
1. Introduction

Certification involves confirmation from an independent third party that a product conforms to the requirements stipulated in standards or other specifications. 

Requirements on environmental or quality system certification or that the company operates structured environmental/quality management work are not part of this document, but these may be a purchaser’s procurement criteria or requirement. 

Euroheat & Power offers through these guidelines, the manufacturers of district heating pipes and fittings called also “supplier” the possibility of product certification and quality marking. 

These certification regulations define the:

  • conditions for certification,
  • implementation stipulations of certification procedure,
  • product technical requirements,
  • type test requirements,
  • requirements on manufacturer’s quality control during production,
  • requirements on periodical external inspections. 

Certification according to these guidelines represents a common tool for the procurement of standardised EN 253, 448, 488, 14419, and EN 15698-1 and EN 15698- 2 products. 

It should be noted, however, that the guidelines cannot cover all possible special cases in which further or restrictive measures may be required. In the same line of thinking, they are not intended to hinder the development of new and better products. Certification does not absolve anyone of responsibility for their own actions. Accordingly, Euroheat & Power disclaims any responsibility for any consequence caused by the certification and/or the application of the certification guidelines by its members or third parties. Nor can Euroheat & Power be held responsible for malfunctioning (financially or otherwise) of the Certification Board. 

These certification guidelines have been prepared by Euroheat & Power Task Force “Transport & Distribution” and updated by the “Certification Board.” 

All producers are encouraged to apply the certification procedure according to these guidelines. 

Euroheat & Power recommends its member associations to refer to these guidelines for the procurement of standardised EN 253, EN 448, EN 488, EN 15698-1, EN 15698- 2 and EN 14419 products. Concerning the products which fall under the scope of these guidelines (see clause 3 of the guidelines), Euroheat & Power strongly encourages its member associations to recommend their member companies to buy and use only certified products. EHP certificate should be part of requirements in invitation to tender documents of the district heating companies. In procurements falling under Public Procurement Directive 2004/17/EC EHP certificate or equivalent third party certificate/declaration should be required. Should products which are not included on the Euroheat & Power Certificate list be offered by the bidder, this shall clearly be stated in the bid to avoid confusion. 

Manufacturers with the right to carry out EHP quality marking are introduced on an open list, which is kept up-to-date by Euroheat & Power.

2. Object

The purpose is to:

  •  provide a voluntary certification system which is economical and beneficial for both suppliers and users
  • provide users an easy way to obtain required assurance of the sufficient quality of the products by introducing a certificate and a quality mark
  • ensure the required quality of products mentioned in chapter 3
  • provide more uniform, equal and fair competition conditions in Europe and avoid unsound price competition at the expense of quality.
3. Scope and requirements

The scope of these certification guidelines covers:

  • district heating pipes (single pipe system) manufactured according to EN 253 “District heating pipes,
  • Preinsulated bonded pipe systems for directly buried hot water networks
  •  Pipe assembly of steel service pipe, polyurethane thermal insulation and outer casing of polyethylene”, fittings manufactured according to EN 448 “District heating pipes, 
  • Preinsulated bonded pipe systems for directly buried hot water networks, 
  • Fitting assemblies of steel service pipes, polyurethane thermal insulation and outer casing of polyethylene”, valve assemblies manufactured according to EN 488 “District heating pipes, 
  • Preinsulated bonded pipe systems for directly buried hot water networks – 
  • Steel valve assembly for steel service pipes, polyurethane thermal insulation and outer casing of polyethylene”, surveillance systems according to EN 14419 “District heating pipes - 
  • Preinsulated bonded pipe systems for directly buried hot water networks – Surveillance systems”, district heating pipes (twin pipe system) manufactured according to EN 15698-1 “District heating pipes,
  • Preinsulated bonded twin pipe systems for directly buried hot water networks-Part 1: Twin pipe assembly of steel service pipes, polyurethane thermal insulation and outer casing of polyethylene” and fittings (twin pipe system) manufactured according to EN 15698-2 “District heating pipes,
  • Preinsulated bonded twin pipe systems for directly buried hot water networks-Part 2: Fitting and valve assembly of steel service pipes, polyurethane thermal insulation and outer casing of polyethylene”. 

Note: EHP001 covers manufacture of valve assemblies (casing and insulation of the fitting).

In case the preinsulated pipe manufacturer does not produce casings, only certified casing pipes are allowed to be used for production of pipes and fittings covered by a certificate. Therefore certificates can also be issued to producers of casing pipes only. 

Product technical requirements and type test requirements are directly adopted from EN 253, EN 448, EN 488, EN 14419, EN 15698-1 and EN 15698-2. Requirements on manufacturer’s quality control and external inspections are adopted from annexes giving guidelines for inspection and testing (annex D of EN 253, A of EN 448, A of EN 488, F of EN 14419, A of EN 15698-1 and clause 1 of EN 15698-2). 

The Certification guidelines can be updated when a new reference standard or revision or amendment of an existing standard has been approved in CEN Formal Vote. 

One and the same certificate can cover both pipes and fittings in both single and twin pipe systems.

4. General rules

All suppliers of pipes and fittings (“supplier”) in accordance with the scope shall have even access to certification on equal financial and other conditions.

5. Administration, organisation

The organisation and the roles and tasks of different bodies are as follows: 

Certification Board:

The Certification Board authorizes certification bodies and controls that the bodies operate according to these guidelines, has full insight in the certification procedures, investigates complaints and makes the final decision, updates the open list of certified products, takes care of matters that can affect this certification programme and updates these guidelines. 

Every EHP member association has a right to nominate one member to the Board. The members shall be employees of district heating companies, district heating associations or testing institutes. Additionally the Board can invite experts. When matters concerning certain certification body are on the agenda, its representative shall take part in that Board meeting. 

The Board meetings take place as often as deemed necessary, but at least once a year. The Board shall meet representatives of certification bodies at times to discuss experiences and routines. 

The decisions of the Board are made on a simple majority basis. In case of even vote the decision will be allotted.

Certification Bodies:

The certification bodies accredited according to EN ISO/IEC 17065 “Conformity assessment. Requirements for bodies certifying products, processes and services” and approved by the Board take care of certification operations and are responsible for reporting to the Board. 

Initial and periodical external inspections are part of the certification process. If the certification body performs the initial and periodic inspections itself, it shall also be accredited according to EN ISO/IEC 17020 “Conformity assessment - Requirements for the operation of various types of bodies performing inspection”. If the certification body uses sub-suppliers for inspections, the sub-supplier must be accredited respectively (ISO/IEC 17020) and approved by the responsible certification body.

Test Institutes:

Type tests and spot tests for samples taken as part of external inspections are carried out and test reports made by test institutes, having a valid accreditation to do specified testing in accordance with the conditions specified by respective EN standards and accredited according to EN ISO/IEC 17025 “General requirements for the competence of testing and calibration laboratories”. If sub-suppliers for tests are used, they must be accredited respectively and approved by the responsible test institute. 

Note: It is up to accredited EHP Certification Bodies to approve Testing Institutes.

Type test report shall show that all the technical requirements set out in annex 1 are satisfied. The report must not be older than two years at the time of application.

Type testing is to be carried out in an accredited test institute to the extent stated in annex 1. Provided that the PE casing materials/suppliers and the foam system used for fitting production are the same as for pipe production, the type test report for straight pipe production covers also fitting production in that production plant. Otherwise a specific type test report for fitting production is needed additionally. For a manufacturer of fittings only, type test specimens can be taken from a pipe, produced in the same production plant and with the same foam system, where necessary. 

For a manufacturer of casing pipes only, the type testing consists of PE tests and shear strength before ageing and impact resistance tests of the pipe assembly.

Type test results only apply to products made of same materials as the type tested products were manufactured of.

The supplier is responsible for sending the samples to the test institute and for the related costs.

 

6.3.1.3 Quality control plan

The quality control plan shall describe the methods and minimum test frequencies applied in manufacturer’s internal quality control for items according to annexes 1 and 2.

 

6.3.2 Marking

Manufacturers have the right to mark the certified products with a certification label (quality mark) consisting of an EHP logo and a certificate number as set out in annex 6. The certificate number is made up of a unique certification body number denoted with two digits and a serial number from 01 to 99.

 

6.4 Initial inspection at production plant

The initial inspection shall provide evidence that the manufacturer meets all the requirements of these certification guidelines. The initial inspection includes inspections and checks included in “manufacturer’s type test” and a check of procedures to perform “manufacturer’s quality control” in accordance with annexes 1 and 2 (inspections and tests according to “external inspection” are not carried out during initial inspection but only during periodical inspections).

 

6.5 Manufacturer’s quality control

Manufacturer’s quality control is performed in order to ensure that certified products continuously satisfy requirements in EN 253, EN 448, EN 488, EN 14419, EN 15698-1 and EN 15698-2. The quality control shall consist of tests, measurements and inspections according to annexes 1 and 2.

The minimum requirements of quality control (items to be tested and test frequencies) are given in annexes 1 and 2. The quality control shall be described in a quality manual or the like.

The quality control tests and measurements can be performed by the manufacturer itself or they can be outsourced to a subcontractor or test laboratory.

Test equipment used for internal inspection shall be well-maintained, adjusted and calibrated.

All quality control tests and measurements shall be documented, giving the information of the samples, results, dates, name of controller and measures implemented due to results. These documents together with documents on manufactured products and received materials and components shall be maintained for at least 6 years and the certification body shall have access to them.

 

6.6 Periodical external inspections

External inspections are performed in order to evaluate the certificate holder’s continued compliance with all the specified requirements for certification, especially the minimum extent and proper functioning of the manufacturer's quality control.

 The inspection is made by the certification body once a year through a visit to the manufacturer at times determined by the body.

Checks will be made during the visit that the manufacturer's quality control works as required and as documented by the manufacturer. Furthermore, testing and inspections and sampling by the certification body of certified products will be carried out according to annexes 1 and 2. Accredited test laboratories shall be employed by the manufacturer to perform tests for samples taken during inspection.

In order to facilitate the follow up of the quality of the delivered products the certificate holder shall keep record of the quality reclamations they receive from the field and the actions they have consequently taken. These records can be checked during external inspections.

If the manufacturer employs a quality system according to EN ISO 9001 certified by an accredited certification body the audit of quality control can be limited to the inspection of conformity of the quality control plan to these guidelines (annex 1 and 2) and the audit and revision reports. 

The results of the inspection shall be reported in writing to the manufacturer and - if the certificate holder is not the same as the manufacturer - also to the certificate holder.

If inspections, testing and/or the audit of the manufacturer's quality control result in non-conformity the certification body initiates an investigation into the causes. The investigation can result in a note, request for corrective acts, new inspection visit, retesting or requirements for changes to the quality control.

 

6.7 Modification of a certified product

The holder of a certificate is obliged to notify the certification body before modifications to the design, material or implementation are made. The certification body then determines whether the modifications are of a type that can be accepted without renewed testing, inspection or revision of the certificate based on the principle described in annex 3.

 

6.8 Modification of standards and certification guidelines

In case of amendment or revision to the relevant EN standards or these certification guidelines a supplementary inspection and/or type testing of the changed element(s) will be required by the certification body in order to prove compliance with the changed requirements in order to re-issue the certificate. The certificate holder should be given reasonable time to adapt to the revised regulations, unless there are special motives for other action. 

7. Conditions for certification and quality marking

7.1 Period of validity for the certificate
