The tensile stress to calculate the pre-stress force is calculated using the following equation:
σt = α × ∆T × E
where σt is the tensile stress, expressed in megapascals ( MPa); α is the coefficient of thermal expansion, expressed per Kelvin (1/K); ∆T is the temperature difference, expressed in Kelvins (K); E is the modulus of elasticity, expressed in megapascals (MPa).
6 Evaluation of conformity 6.1 General The conformity of pipes and fittings with the requirements of this standard and with the declared values (including classes) shall be demonstrated by:  initial type testing;  factory production control by the manufacturer, including product assessment. For the purposes of testing, pipes and fittings may be grouped into families, where it is considered that the results for one or more characteristics from any product within the family are representative for the same characteristics for all products within that family. NOTE 1 A product can be in more than one family for different characteristics. For type testing the following family groups applies. a) Pressure groups for pipes and fittings as given in Table 2. Table 2 — Pressure groups Pressure group Design pressure, PD bar 1 ≤ 6 2 > 6
b) Size groups for pipes and fittings as given in Table 3. SIST EN 15015:2008

Size group Range of nominal diameters, dn 1 dn ≤ 63 2 63 < dn ≤ 160
c) Fitting groups for fittings as given in Table 4. Table 4 — Fitting groups Fitting group Fittings 1 Elbows and tees 2 Reducers, couplers, end caps 3 All fittings except those included in group 1 and group 2.
6.2 Initial type testing 6.2.1 General Relevant type tests shall be carried out on new products and whenever there is a change in design, in material and/or in production method, other than routine in-process adjustment and extension of the product range (see Table 3). A change of supplier of a material or stabiliser does not lead to a change in performance if the chemical composition remains the same. Material modifications within certain limits are not considered as a change of material. Guidance for these limits can be found in the standards given in Annex C. For tests previously performed in accordance with the provisions of the standards listed in Annex B, or the recognized European specification, as applicable, (same product, same characteristic(s), same test method, same system of attestation etc.) the results may be taken into account. All characteristics given in Clause 4 shall be subject to calculation and/or initial type testing, except 4.5.3, where the characteristics of the components used have already been determined by the component manufacturer on the basis of conformity with other product standards. However this does not relieve the manufacturer of the piping system from the responsibility of ensuring that the system conforms to the requirements of this document. 6.2.2 Initial type test requirements The initial type testing of the characteristics according to Clause 4 shall be performed in accordance with the sampling procedure given under type tests (TT) of the applicable product specific standards for assessment of conformity as given in Annex C. If the standard does not contain one or the other of the characteristics, then testing as given in Table 5 shall apply. For products where no such standard exists Table 5 shall apply.

D is change of fitting design;
E is extension of the product range with new pressure group, size group or fitting group;
+ denotes testing relevant for the characteristic-occurrence-combination. b Only obligatory if subject to regulatory requirements applicable in the place of use.
Test reports shall be kept by the manufacturer for at least 10 years after discontinuation of the product. 6.3 Factory production control 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market conform to the stated performance characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. If the manufacturer has the component designed, manufactured, assembled, packed, processed and labelled by subcontracting, FPC of the original manufacturer may be taken into account. However, where subcontracting takes place, the manufacturer shall retain the overall control of the component and ensure that he receives all the information that is necessary to fulfil his responsibilities according to this European Standard. The manufacturer who subcontracts all of his activities may in no circumstances discharge himself of his responsibilities to a subcontractor. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of conformity evaluation and enable the achievement of the required component characteristics and the effective operation of the production control system to be checked. Factory production control therefore brings together operational techniques and all measures allowing maintenance and control of the conformity of the component with its technical specifications. Its implementation may be achieved by controls and tests on raw materials and constituents, processes, manufacturing equipment and finished components, including material properties in components, and by making use of the results thus obtained.
