EN 14814:2016 (E) 10 When the adhesive is specified for a piping system with conical fittings, these fittings shall be used for testing the internal pressure resistance. The inside diameter of the sockets shall be in accordance with the relevant standards. 5.3 Shelf life The producer shall recheck the film properties (see Annex A) and the shear strength (setting time 24 h) of the adhesive after the recommended shelf life (minimum 12 months). The adhesive, stored in unopened containers in accordance with the manufacturer's instructions for the specified shelf life shall still meet the requirements of Table 4. 5.4 Release of dangerous substances The release of dangerous substances shall comply with the existing national regulation. 5.5 Durability The durability of tightness and resistance to high temperature of the adhesive joints is assessed by the internal pressure test and shall comply with 5.2. 6 Assessment and verification of constancy of performance — (AVCP) 6.1 General The compliance of adhesives for thermoplastic piping systems under pressure with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product type; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, classified without further testing (CWFT) and conventionally accepted performance). Assessment 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 AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for that same characteristics for all products within that same family. Products may be grouped in different families for different characteristics. Example: Products/Formulations which only differ in colour or slightly in viscosity can be considered as one product family. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. SIST EN 14814:2016

EN 14814:2016 (E) 11 In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production of a new or modified adhesive for thermoplastic piping systems under pressure (unless a member of the same product range), or — at the beginning of a new or modified method of production (where this may affect the stated properties); or — they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the adhesive for thermoplastic piping systems under pressure design, in the raw material or in the supplier of the components, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the DoP, although this does not replace the responsibility on the adhesive for thermoplastic piping systems under pressure manufacturer to ensure that the adhesive for thermoplastic piping systems under pressure as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2 Test samples, testing and compliance criteria The number of samples of adhesives for thermoplastic piping systems under pressure to be tested/assessed shall be in accordance with Table 6. Table 6 — Number of samples to be tested and compliance criteria Characteristic Requirement Assessment method No. of samples Compliance criteria Resistance to pull out at 1 h setting time (Shear strength) 4.2 5.1 One sample See Table 4 Resistance to pull out at 24 h setting time (Shear strength) 4.2 5.1 One sample See Table 4 Resistance to pull out at 480 h setting time (Shear strength) 4.2 5.1 One sample See Table 4 Internal pressure 4.3 5.2 One sample 5.2 Resistance to high temperature 4.4 5.2 One sample 5.2 Shelf life 4.5 5.3 One sample 5.3 at producer’s specified shelf life Release of dangerous substances 4.6 5.4

EN 14814:2016 (E) 12 6.2.3 Test reports The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the adhesive for thermoplastic piping systems under pressure to which they relate. 6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market comply with the declared performance of the essential 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. 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 factory production control system documentation shall ensure a common understanding of the evaluation of the constancy of performance and enable the achievement of the required product performances 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 compliance of the product with the declared performances of the essential characteristics. 6.3.2 Requirements 6.3.2.1 General The manufacturer is responsible for organizing the effective implementation of the FPC system in line with the content of this product standard. Tasks and responsibilities in the production control organization shall be documented and this documentation shall be kept up-to-date. The responsibility, authority and the relationship between personnel that manages, performs or verifies work affecting product constancy, shall be defined. This applies in particular to personnel that need to initiate actions preventing product non-constancies from occurring, actions in case of non-constancies and to identify and register product constancy problems. Personnel performing work affecting the constancy of performance of the product 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 constancy of performance of the product at appropriate stages; — identify and record any instance of non-constancy; — identify procedures to correct instances of non-constancy. The manufacturer shall draw up and keep up-to-date documents defining the factory production control. The manufacturer's documentation and procedures should be appropriate to the product and manufacturing process. The FPC system should achieve an appropriate level of confidence in the constancy of performance of the product. This involves: SIST EN 14814:2016

EN 14814:2016 (E) 13 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-constancy of performance. 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 fulfill his responsibilities according to this European Standard. If the manufacturer has part of the product designed, manufactured, assembled, packed, processed and/or labelled by subcontracting, the FPC of the subcontractor may be taken into account, where appropriate for the product in question. The manufacturer who subcontracts all of his activities may in no circumstances pass the above responsibilities on to a subcontractor. NOTE Manufacturers having an FPC system, which complies with EN ISO 9001 standard and which addresses the provisions of the present European Standard are considered as satisfying the FPC requirements of the Regulation (EU) No 305/2011. 6.3.2.2 Equipment 6.3.2.2.1 Testing All weighing, measuring and testing equipment shall be calibrated and regularly inspected according to documented procedures, frequencies and criteria. 6.3.2.2.2 Manufacturing All equipment used in the manufacturing process shall be regularly inspected and maintained to ensure use, wear or failure does not cause inconsistency in the manufacturing process. Inspections and maintenance shall be carried out and recorded in accordance with the manufacturer’s written procedures and the records retained for the period defined in the manufacturer's FPC procedures. 6.3.2.3 Raw materials and components The specifications of all incoming raw materials and components shall be documented, as shall the inspect
