Plastics piping systems for water supply Polyethylene (PE) Part 1: General, Part 2: Pipesand Part 3: Fittings

Foreword

EN 12201 specifies the requirements for a piping system and its components when made from polyethylene(PE). It is intended to be used for water supply intended for human consumption, including the conveyanceof raw water prior to treatment. This Specific rules (SBC) cover compound, pipes and fittings.

To comply with expressed request from the market, and in expectation of the revision of EN 12201, this SBCalso covers certification of pipes with dimensions according to ISO 4427 that are not covered byEN 12201.

4.1 Type testing and inspection

The type control includes type testing and initial inspection.

4.1.1 Type testing

Type testing is carried out on compound, pipes and fittings, which are to be included in the certificationlicense and to the extent stated in Table 3, 4 and 5. On request by the applicant the type test is carried outby an approved testing laboratory according to Annex A to this SBC. The type test report shall confirm thatall requirements are fulfilled with regard to the relevant compound and pipes/fittings and verify that themanufacturers test results are available and fulfils the requirements in this SBC. The type test report shallstate the designation of material from which the pipes and fittings are made.

4.1.2 Ini tial inspection

The initial inspection shall be carried out by an approved inspection body according to Annex A to this SBC.

The initial inspection forms part of the type test and shall verify that the manufacturers system for qualityassurance for relevant products comply with the below notes and clause 4.2.1.

Documented routines shall cover:

- Disposition of responsibility- Documentation (manual or document shall refer to INSTA-CERT GRC and this SBC) and validstandards for actual products) shall be available for the personnel involved.- Purchase and reception control, stocking of raw material- Factory production control- Recording of the results from the internal inspection including handling records in electronic form- Deviations and corrective actions- Calibration of control, measuring and testing equipment with traceability to accredited calibrated

instrument- Final control of finished product (correct marking, to ensure that specified requirements are fulfilled)- Handling of finished product (stocking, packaging and delivery) to prevent damages- Claims- Traceability from products to internal records

In case the applicant has a valid INSTA-CERT licence for similar products this shall be taken inconsideration when deciding in the extent of initial inspection

At the preliminary inspection it shall be evaluated if the resources of the manufacturer are sufficient toensure a satisfactory quality level on the products and to carry out internal testing according to clause4.2.1.

4.2 Factory production control

4.2.1 Internal testing

The manufacturer is responsible for demonstrating through described procedures and written instructionsthat INSTA-CERT marked pipes and fittings included in the certification licence fulfil the requirements in thisSBC.

The internal testing is carried out partly as batch release test, BRT, with the minimum extension stated inTables 6, 7 and 8 attached to this SBC, and as process surveillance process verification test, PVT, carriedout according to Tables 9, 10 and 11. Documentation from the control should be kept for 5 years.

The licensee/manufacturer is responsible for ensuring that the instructions concerning the internal qualityinspection are available for the personnel in the language of the manufacturing country concerned.

Records of the internal control shall be signed, dated and be available to the controller at the external controlaccording to clause 4.3.1.

The records shall include information of - or traceability to

- Type of raw material- Certificate ofraw material- Receipt identification/ designation- Batch number- Date of production

If the tested pipes and fittings do not fulfil the requirements the manufacturer/licensee must immediatelyinitiate the necessary corrective actions to ensure that the products fulfil the requirements, see clause 8.2batch release tests in this SBC.

Sales of the defective products have been prevented.

4.3 Audit testing and inspection

Audit testing and inspection of pipes and fittings shall be carried out twice a year and for compounds once ayear by an approved inspection body and testing laboratory according to annex A of this SBC (see 4.3.3)

4.3.1 Inspection

The inspection includes

- review of the manufacturers documentation of the internal testing according to clause 4.2.1including inspection of records as well as inspection of the manufacturers testing equipment andcalibration of measuring and testing equipment used.

- storage, packing and delivery of final products. In addition also random surveillance of the qualityinsurance routines is made according to 4.1.2.

- compound, pipes and fittings are sampled from the manufacturers stock for audit testingaccording to clause 4.3.2.

4.3.2 Audit testing

Testing is carried out according to Tables 12, 13 and 14 attached to the present SBC covering compound,pipes and fittings with sizes representative for the manufacturers production. All test results should bedocumented in a report stating the designation of the material used in the tested pipes and fittings.

4.3.3 Results from inspection and testing

If the requirements are not fulfilled the certification body decides, if necessary in consent with the inspectionbody and/or testing laboratory concerned, which actions shall be taken.

Deficiencies in the internal control and/or in the test results may result in a cancelling of the approvalmarking temporarily or definitely until actions are taken to state correct quality. The certification body mayeven extend the number of testing to be carried out within a fixed period.

4.4 Other testing and inspection

Other testing and inspection may be carried out under the conditions stated in INSTA-CERT GRC.

4.5 Control by change of material or production conditions

For definition of change of material for the compound manufacturer see CEN/TS 12201-7:2003, Annex A.

The licensee shall in advance inform the certification body of change of compound/recipe, design orproduction method. Tables 4, 5 and 6 describe the extent of the control due to the change.

The licensee is not allowed to mark any changed product with the conformity mark without a written

permission from the certification body.

5 MARKING

Compounds, pipes and fittings included in the issued certification license shall in connection with theconformity mark, see Annex B, be marked with:

1. The conformity mark2. Information according to EN 12201-2 clause 11 including pressure class achieved applying the

lowest design factor or EN 12201-3 clause 11 respectively3. If relevant an assigned identity number4. If relevant DS and/or FI-mark, see clause 0 Information

If a product fails in respect to any characteristics stated in tables 6, 7 or 8 the batch shall be rejected or there-test procedure shall be performed for the characteristic on which the product failed.The following procedures shall then be carried out:

- Find the last product, which conforms to the requirements specified in EN 12201. Release allproducts produced before that point and reject the products after that point.

- Routines for handling rejected products shall be described in the manufacturers quality plan.

INSPECTION BODIES AND TESTING LABORATORIES

1 Inspection Body

An inspection body, which fulfils the requirements stated in ISO 17020, shall assess the manufacturersinternal routines specified in clauses 4.1.2 and 4.3.1.

The certification body is responsible for the evaluation of the inspection body.

2 Testing laboratories

Type testing and audit testing of compounds, plastic pipes and fittings for certification in conformity withthe requirements in EN 12201 shall preferably be carried out by a testing laboratory accredited accordingto ISO 17025.

The accreditation shall include the testing standards stated in EN 12201.

In case no testing laboratory is accredited to test one or more characteristics, a non-accredited report canbe accepted after agreement with INSTA-CERT.
