In accordance with the scope, all manufacturers shall have equal access to the certification programme mentioned in this guideline under the same conditions (financial and other).
Technical requirements for pipe, fitting and valve assemblies like the guideline for inspection and testing, are adopted without any changes from EN 253, EN 448, EN 488-1, EN 488-2, EN 14419, EN 15698- 1 and EN 15698-2.
Note: The guideline for certification and testing is covered in the manufacturer´s type test, the manufacturer´s quality control and external inspection.
If the manufacturer of factory-made pipe, fitting and valve assemblies does not produce casing pipes, only casing pipes certified by EHP001 shall be used to produce the assemblies covered by a certificate.
Certificates shall, therefore¸ also be issued to manufacturers who only produce casing pipes.
The procedure to obtain and uphold a certificate involves:
- initial assessment of the application documents,
- initial inspection at the production plant,
- manufacturer's quality control
- periodical external inspections.
The type testing, initial assessment of documents and initial inspection are performed to obtain an initial validation of materials, products, production processes and the manufacturer's quality control. After successfully passing these procedures, the certificate will be issued.
If the results of the type tests and inspections do not meet the requirements to obtain a certificate, the applicant shall apply corrective measures. Subsequently, the Certification Body shall determine which parts of the tests and/or inspections shall be repeated.
Manufacturers shall submit a written application form (1.1) to the Certification Body.
The application shall be accompanied by technical data (declaration of conformity regarding type test reports, drawings, etc.) according to 5.3.1.
The application form shall be used to apply for an extension of scope of the existing certificate and in case of changes to the location where the certified product is manufactured.
5.3. Initial assessment of application documents
During the initial assessment, the Certification Body shall examine the documents submitted against the requirements set out in this guideline
The applicant shall present technical data for the product, which includes, (as applicable):
- product description,
- reference to relevant standards according to clause 3,
- type test report,
- quality control plan,
- Information about the product’s intended marking.
Note: The report of the initial inspection shall be sent to the Certification Body.
- 184.108.40.206. Product description
The product description shall clearly show the number or designation, as well as the date of the last revision.
- 220.127.116.11. Type test report
The type test report shall confirm that all the technical requirements set out in ANNEX 1 are fulfilled. The type test report shall not be older than two (2) 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/manufacturers and the foam system for thermal insulation used to manufacture fitting and valve assemblies are the same as those used to manufacture pipe assemblies, the type test report for pipe assemblies will cover fitting and valve assemblies manufactured in the certified production plant. Otherwise, a specific type test report for the production of fitting and valve assemblies is needed.
For type test, manufacturers of fitting and valve assemblies shall only use samples taken from pipe assemblies manufactured in the same production plant which use the same foam system for thermal insulation.
For manufacturers that only produce casing pipes, the type testing consists of PE tests.
Type test results only apply to products made of the same materials as the type tested products.
The manufacturer is responsible for sending the samples to the Test Institute and for the associated costs.
Disclaimer: These fees are determined by and payable to the Certification Body or Test Institute. Euroheat & Power is in no way involved and disclaims any responsibility.
- 18.104.22.168. Quality control plan
The quality control plan shall describe the methods and the minimum test frequency applied during the manufacturer’s internal quality control for items described in ANNEX 1 and ANNEX 2.
Manufacturers have the right to mark the certified products with a certification label (Quality Mark) consisting of a Euroheat & Power logo and a certificate number as set out in ANNEX 6. The certificate number consists of a unique Certification Body number denoted with two digits and a serial number starting from 01.
5.4. Initial inspection at production plant
The initial inspection shall take place at the production plant and provide evidence that the manufacturer meets all the requirements specified in this certification guideline.
It shall include inspections and checks which are part of the “manufacturer’s type test” and a check of procedures to perform the “manufacturer’s quality control” in accordance with ANNEX 1 and ANNEX 2 (inspections and tests according to “external inspection” are not carried out during the initial inspection but only during periodical inspections).
5.5. Manufacturer’s quality control
The manufacturer’s quality control is performed in order to ensure that certified products continuously meet the requirements of EN 253, EN 448, EN 488-1, EN 488-2, EN 14419, EN 15698-1 and EN 15698-2. The quality control shall consist of tests, measurements and inspections as specified in ANNEX 1 and ANNEX 2.
The minimum requirements for the quality control (items to be tested and test frequency) are set out in ANNEX 1 and ANNEX 2. The quality control shall be described in a quality control manual or in a similar document.
Quality control tests and measurements can be performed by the manufacturer or can be outsourced to a subcontractor or test laboratory.
Test equipment used for internal inspections shall be well-maintained, adjusted and calibrated.
All quality control tests and measurements shall be documented. They shall provide the following information:
- test results,
- name of the person who performs the tests and,
- measures implemented in accordance with the results.
The above-mentioned documents and the documentation on the manufactured products, materials received and components shall be kept for at least ten (10) years and the Inspection Body shall be given access to them.
5.6.Periodical external inspections
External inspections are performed in order to evaluate the Manufacturer`s continued compliance with all the specified requirements for certification, especially testing frequency, the extent of testing and the proper functioning of the manufacturer's quality control.
The inspection is to be carried out by the Inspection Body once a year through a visit to the certified production plant at times determined by the Certification Body.
Checks will be made during the visit to ensure that the Manufacturer's quality control works and is documented as required. Furthermore, the Inspection Body shall carry out testing, inspections and sampling of the certified products according to ANNEX 1 and ANNEX 2. The manufacturer shall work with accredited test laboratories to perform tests on samples taken during the inspection.
To facilitate the follow up of the quality of the delivered products, the Manufacturer shall keep records of the complaints received and the actions subsequently taken. These records can be checked during external inspections.
If the Manufacturer employs a quality system according to EN ISO 9001 which is certified by an accredited Certification Body for the certification of quality management systems, the quality control audit can be limited to the inspection of conformity of the quality control plan to this guideline (ANNEX 1 and ANNEX 2), the audit and revision reports.
The results of the inspection shall be reported in writing to the Manufacturer.
If inspections, testing and/or the audit of the manufacturer's quality control result in non-conformity, the Certification Body shall initiate an investigation into the causes. The investigation can result in a written caution, a request for corrective action, a new inspection visit, new tests or a request to make changes to the quality control.
5.7. Changes to certified products
Manufacturers shall notify the Certification Body before changes to the design, material or implementation are made. The Certification Body will then determine whether the changes can be accepted without new tests, inspection or revision of the certificate based on the principle described in ANNEX 3.
5.8. Modification of standards and certification guideline
In case of amendment or revision of the relevant EN standards or, of this certification guideline, the Certification Body may require an additional inspection and/or type testing of the changed element(s) to ensure compliance with the revised requirements. The certificate may be eventually re-issued. The certification board shall notify all certification bodies in a timely manner about the transition procedure and timeframe. The Manufacturer shall be given reasonable time to adapt to the revised regulations unless there are special reasons for other action.
