0 INFORMATION Denmark and Finland have specific national requirements for drinking water products: the DK-VAND approval is required in Denmark, and the FI-mark is required in Finland.

1 CONDITIONS FOR CERTIFICATION The issuance of a certificate requires that the applicant commits himself to follow the ”General Rules for Certification provided by INSTA-CERT” (hereafter INSTA-CERT GRC) and the specific rules, but also to make sure that the products mentioned fulfil the requirements of EN 12201.

The compounds, for manufacturing of pipes and fittings, must have an INSTA-CERT certificate. Products made from external non-virgin materials cannot be certified under this INSTA-CERT system. The certification of fittings covers also fabricated fittings size group 1, 2, 3 and 4, see Annex C. The INSTA-CERT certification system covers blue or black pipes. In addition, black pipes may have coloured identification stripes. For pipes with peel-able layer the colour of the outer layer shall be in accordance with the manufacturer’s specification. Pipe constructions including diffusion barrier layers are not covered by this INSTA SBC. Such pipe constructions are covered by ISO 21004.

3 CERTIFICATE

The certificate will be issued when the type test reports prove that the requirements of EN 12201 and this SBC are fulfilled and that other application initiatives according to clause 2 are approved. A certificate according to this SBC only covers one manufacturer and products from one production site. For a manufacturer extending the scope of certification to another production site with products covered by this SBC one of the following alternatives shall be followed: 1. Type testing is performed by an approved test laboratory according to Table 12, 13, 14 or C1, Audit Test. A

certificate may be issued when the approved results are available for the short-time tests.

2. The manufacturer shall carry out a preliminary type test (PTT) according to Table 12, 13, 14 or C1, Audit Test. The certificate may be issued as soon as the approved results are available for all tests, and pipes are submitted for testing at an approved test laboratory.

Both alternatives imply that the production and the quality assurance system for the actual production sites are similar. This is verified through an assessment of the quality system and an initial inspection at the production site. A report shall be available before the certificate can be issued.

The correlation between compound designation, design coefficient C, SDR, S and PN for the permitted range according to this SBC is shown below, Table 0. Table 0

4.2 Factory production control

4.2.1 Internal testing

Through described procedures and written instructions the manufacturer is responsible for demonstrating that INSTA-CERT marked compound, pipes and fittings included in the certificate fulfil the requirements of EN 12201 and this SBC. The internal testing is performed partly as a batch release test (BRT) with the minimum content as stated in Tables 6, 7, 8 and C.1 attached to this SBC, and partly as a process verification test (PVT) performed according to Tables 9, 10, 11 and C.1. The documentation of the testing should be kept for at least 5 years. The certificate holder/manufacturer is responsible for ensuring that instructions concerning internal quality inspection are available for the personnel in the language of the country concerned. Records of the internal testing shall be signed, dated and shall be available for the external inspector according to clause 4.3.1. The records shall include information of or traceability to: - Type of raw material

- Certificate of raw material

- Compound identification/designation

- Batch number

- Date of production

If the tested pipes and fittings do not fulfil the requirements, the manufacturer/certificate holder must immediately initiate the necessary corrective actions to ensure that the products fulfil the requirements, see clause 8.2, batch release tests, in this SBC. It shall be prevented that defective conformity marked products are put on the market. If the tested compound, pipes and fittings do not fulfil the requirements the manufacturer/certificate holder must immediately initiate the necessary corrective actions to ensure that the products fulfil the requirements, see clause 8.2 batch release tests, in this SBC. Sales of defective conformity marked products shall be prevented.

4.3 Audit testing and inspection

Audit testing and inspection of compounds shall be performed once per year by an approved inspection body and testing laboratory according to Annex A to this SBC. Audit testing and inspection of pipes and fittings shall be performed normally twice per year by an approved inspection body and testing laboratory according to Annex A to this SBC.

4.3.1 Inspection

The inspection includes: - Review of the manufacturer’s documentation of the internal control according to clause 4.2.1 including

inspection of records as well as inspection of the manufacturer’s test equipment and calibration of measuring and test equipment used.

- Checking of storage, packaging and delivery of final products. In addition, random surveillance of the quality insurance routines is carried out according to 4.1.2.

- Sampling of certified products from the manufacturer's stock. The samples shall be signed by the inspector and subsequently the samples shall be sent to the test laboratory for testing according to 4.3.2.


Page 7 of 25

4.3.2 Audit testing The testing shall be performed according to Tables 12, 13, 14 and C.1 covering compounds, pipes and fittings with sizes representative for the manufacturer’s production. All test results shall be documented in a report stating the designation of the material and sealing rings used for 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 inspection body and/or test laboratory concerned - which actions to be taken. Deficiencies in the results of the external or internal testing or inspection may cause withdrawal of the right to use the conformity mark until sufficient actions have been taken to ensure the quality. Additionally, the certification body may increase the number of external inspections for a certain period of time.

4.4 Other testing and inspection

Other testing and inspection may be performed according to the conditions stated in INSTA-CERT GRC.

4.5 Control at change of material, design or production methods

In advance, the certificate holder shall inform the certification body of all changes of recipes/compounds, design and production methods. Tables 4, 5 and 6 describes the extent of the control caused by the changes. The certificate holder is not allowed to mark any changed products with the conformity mark without a written permission from the certification body.

5 MARKING Compounds, pipes and fittings included in the certificate shall at least be marked with:

1. The conformity mark, see Annex B 2. Information according to EN 12201-2 clause 11 including pressure class achieved applying the

lowest design factor or EN 12201-3 clause 11 respectively, except: - the additional marking regarding the removal of the outside layer of the peel-able pipes; - the marking with codes for the intended use (P, W or W/P).

3. If the peel-able layer must be removed before buttfusion, this relevant info shall be marked on the peel-able layer.

4. If relevant DK-VAND - and/or FI - mark, see clause 0 Information

Marking according to items 1 to 4 shall be approved by the certification body. Any additional marking shall not be in conflict with marking according to items 1 to 4.

8.2 Batch Release Test, BRT Batch release testing shall be performed by the manufacturer and includes determination of the characteristics listed in Tables 6, 7 and 8 with the specified minimum sampling frequencies. For fittings made of approved pipes, the BRT shall be performed in accordance with table C.1. A production batch shall be released for delivery only when the BRT shows conformity with the requirements of EN 12201 and this SBC. The maximum extent of a production batch is seven days without change of material or dimension. If a product is rejected due to lack of the quality stated in Tables 6, 7, 8 or C1, the batch shall be scrapped or a retest procedure shall be performed for the specific character/part of the product that has been rejected. The following procedures shall then be performed: 1. The latest product which fulfils all the requirements specified in EN 12201 shall be traced. 2. The products which have been produced before this date can be released, and the products which have

been produced after this date shall be rejected. 3. Routines for handling deviating products shall be described in the manufacturer’s quality plan.
