The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product.
5.2.1 General Initial type testing and type testing shall be performed to demonstrate compliance of the products with the relevant specific product standards.
All essential characteristics in bold in Table 1 for which the manufacturer declares performances, are subject to initial type testing. In addition, the need to perform Type Tests applies to the characteristics according to 5.2.2 and 5.2.3 when the manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously existing data, CWFT and conventionally accepted performance) for declaring performances without performing tests. Tests previously performed in accordance with the provisions of this standard may be taken into account provided that they were made to the same or a more rigorous test method, under the same system of attestation of conformity on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. ITT shall be performed at the beginning of the production of a new type of the product or at the beginning of a new method of production, where this may affect the stated properties. Tests previously performed in accordance with the provisions of the specific product standard (i.e. same product, characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account for the ITT purpose of that specific product. Where components of the products are used whose characteristics have already been determined by the component manufacturer on the basis of conformity with other product standards, these characteristics need not be reassessed provided that  the components’ performance or method of assessment remain the same,
 the characteristics of the component are suitable for the intended end use of the finished product, and
 insofar as the manufacturing process does not have a detrimental effect on the determined characteristics. Components and raw materials, marked in accordance with appropriate harmonised European specifications, may be presumed to have performances as declared. However, this does not replace the responsibility of the product manufacturer to ensure that such products, as a whole, are correctly designed and their components have the necessary performance values to meet the design according to the relevant specific product standard. Tests shall be repeated for the appropriate characteristics wherever a change occurs in the product design, in the raw material or in the supplier of the components, or in the production process, which could affect significantly one or more of the characteristics. Full reports of these tests shall be retained by the product manufacturer and shall be available for examination. Complete test reports shall be kept for at least 10 years. 5.2.2 Sampling procedure Test samples shall be selected from a batch at random, without any consideration given to the condition or quality of the selected products. Sampling shall be carried out in accordance with Tables 1 to 5 according to the relevant specific product standard.

5.2.3 Test reports The results of all type tests shall be recorded and held by the manufacturer for at least 10 years after the last date of production of the product(s) to which they apply. SIST EN 295-2:2013

The manufacturer shall draw up and keep up-to-date documents defining the factory production control. The manufacturer's documentation and procedures, including regular internal inspections and test and/or assessments and the use of the results to control raw and other incoming materials or components, equipment and the production process, should be appropriate to the product and manufacturing process. The FPC system should achieve an appropriate level of confidence in the conformity of products placed on the market. This involves: a) the preparation of documented procedures and instructions relating to factory production control operations, in accordance with the requirements of the technical specification to which reference is made; b) the effective implementation of these procedures and instructions; c) the recording of these operations and their results; d) the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-conformity. The responsibility, authority and the relationship between personnel that manage, perform or verify work affecting product conformity, shall be defined. This applies in particular to personnel that need to initiate actions preventing component non-conformities from occurring, actions in case of non-conformities and to identify and register component conformity problems. Personnel performing work affecting component conformity shall be competent on the basis of appropriate education, training, skills and experience for which records shall be maintained. In each factory, the manufacturer may delegate the action to a person having the necessary authority to:  identify procedures to demonstrate conformity of the product at appropriate stages;
 identify and record any instance of non-conformity;  identify procedures to correct instances of non-conformity. Where subcontracting takes place, the manufacturer shall retain the overall control of the product and ensure that he receives all the information that is necessary to fulfil his responsibilities according to this European Standard. SIST EN 295-2:2013

a) alterations to firing conditions (other than those required to maintain a setting); b) a clay blend formula is changed; c) any experimental work with temperature or clay blends. 5.3.7 Records Records shall be maintained for a minimum period of 10 years, including the following: a) data indicating the blend (or stockpile) of clay used and the dates of production of fired ware manufactured from that blend from any kiln; b) details of pipes and fittings, which have been glazed and the glaze used; c) details of fired fittings, which have been surface treated after firing together with the specification(s) of materials used; d) the specification of materials used for fixing fired parts together with supplier(s)´s declaration(s) in respect of each consignment of the material showing compliance with the specification(s); e) functional dimensions for sealing elements and fairings for every design and nominal size of flexible mechanical joint; f) details of materials used for fairings or sealing elements for every design and nominal size of flexible mechanical joint, together with supplier(s)´s declaration(s) in respect of each consignment of the material showing compliance with the specification(s). 5.3.8 FPC testing of pipes, special fittings, adaptors and compatible accessories manholes and inspection chambers, perforated pipes and jacking pipes 5.3.8.1 Requirements, tests and test frequencies
