4.2 Release of dangerous substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material of permited in the national regulations of the member state of destination. 5 Evaluation of conformity 5.1 General
The compliance of liquid-applied water impermeable products with the requirements of this standard and with the declared values (including classes) shall be demonstrated by: Initial Type Testing (ITT); Factory Production Control (FTP) by the manufacturer, including product assessment. 5.2 Initial type testing On first evaluation of a product to the requirements of this European Standard, or before the beginning of sale of a new product, appropriate initial type testing shall be carried out to confirm that the characteristics of the product meet the requirements of this European Standard. Tests which have previously been performed in accordance with the provisions of this European Standard (same product, same characteristic, test method, SIST EN 14891:2012
EN 14891:2012 (E) 8 sampling procedure, etc.) may be taken into account for the purpose of demonstrating satisfactory initial type testing. In these cases the appropriate initial type testing to be carried out shall be for those characteristics and properties that can be affected and need confirmation; any new property or properties arising from a change of formulation or manufacturing procedure shall be tested and the results reported. The initial type testing shall be performed as listed in Table 2. The results of initial tests shall be recorded and be available for inspection. They shall be kept for at least 10 years after the date of last manufacture of the product to which they relate. Only one ITT is required where different manufacturing units are producing the same product, for the same manufacturer, using the same materials (having the same performance) and documented production and process control. Where components (e.g. cement) are used whose characteristics have already been determined by the component supplier on the basis of conformity with other product standards, these characteristics need not be re-assessed to demonstrate compliance with the European Standard. Retesting due to a new method of production or product modification, or change of supplier of components, shall only be performed if one or more of the stated performance characteristics will be downgraded, i.e. the mix design becomes dissimilar. A manufacturer may, however, always retest if he wishes to declare improved performance. 5.3 Factory Production Control 5.3.1 General 5.3.1.1 Factory Production Control plan and procedures A Factory Production Control (FPC) plan shall be established and documented in a manual. Any change in raw materials, manufacturing procedures or control plan that can affect the properties of the product shall be recorded. The manual shall include the FPC procedures relevant to the declared properties, as confirmed by the initial tests. The FPC procedures shall consist of a system for the production quality control to ensure that the product conforms to this European Standard. The production control shall consist of the following main phases: inspection and testing of raw materials; inspection and testing of production equipment and process; inspection and testing of finished products. NOTE Manufacturers having a Quality System complying with EN ISO 9001 [3] and made specific to the requirements of this European Standard are assumed to meet the requirements related to Factory Production Control.
5.3.1.2 Raw materials The acceptance criteria and control procedures for incoming materials shall be defined by the manufacturer, to ensure that these are not used until it has been verified that they conform to the required specifications. SIST EN 14891:2012
EN 14891:2012 (E) 9 5.3.1.3 Production process The manufacturer shall identify and define the plant and production processes and ensure that the processes are carried out under controlled conditions clearly described in documented operating procedures. The processes shall be verified by means of inspections and testing documented in a plan, as frequency and values or criteria required, both on equipment and on operations in the process. The action to be taken when control values or criteria are not obtained shall be given. 5.3.2 Finished products As appropriate, the factory production control system incorporates a sampling plan and the frequency of testing for the finished product. The number and size of the samples, the frequency of sampling, the tests performed and the results obtained, shall be recorded. The frequency of sampling and testing can be determined from statistical principles, ensuring that the corresponding production conforms to the compliance criteria in this European Standard and achieves the required values for products. The tests can also be performed with the frequency described in Table 2. These records shall be available for inspection. Table 2 — Initial type testing and production control frequency Characteristic Test method Initial type test Production control frequency Initial tensile adhesion strength A.6.2 y A Tensile adhesion strength after water contact A.6.3 or A.6.4 y A Tensile adhesion strength after heat ageing A.6.5 y A Tensile adhesion strength after freeze-thaw cycles A.6.6 y A Tensile adhesion strength after contact with lime water A.6.9 y A Waterproofing A.7 y A Crack-bridging ability under standard conditions A.8.2 y A Tensile adhesion strength after contact with chlorinated water A.6.7 or A.6.8 (y) (A) Crack-bridging ability at low temperature A.8.3 (y) (A) NOTE y means « yes » ; (y) means « yes, if relevant for the product ».
A means «at six month interval»; (A) means «at six month interval, if relevant for the product».
For the purpose of the Factory Production Control alternative tests to those given in Table 2 may be used, provided that a correlation of the results between both tests, for the product in question, is established. The use of alternative tests shall be recorded, maintained and be made available on request. 5.3.3 Equipment All the measuring instruments used for production or testing shall be identified, calibrated and kept in good order, in accordance with documented procedures and instructions. The manufacturer shall establish an appropriate plan detailing the procedures and frequency of these checks and shall maintain the registrations. Test equipment shall be calibrated to traceable standards. SIST EN 14891:2012
EN 14891:2012 (E) 10 5.3.4 Statistical techniques Where and when possible and applicable, the results of inspections and testing shall be interpreted by means of statistical techniques, by attributes or by variables, to verify the product characteristics and to determine if the production conforms with the compliance criteria and the product conforms to the declared values. 5.4 Registration, traceability and nonconforming materials 5.4.1 Registration The records of inspections and testing shall be collected, stored and retained in a way to prevent damage, deterioration or loss. These records shall be maintained for 5 years and shall be made available on request from a relevant party. 5.4.2 Identification and traceability Where appropriate, the manufacturer shall establish and maintain in the FPC manual suitable procedures for the identification and traceability of materials from receipt of raw materials and during all stages of production and delivery. 5.4.3 Non-conforming materials and corrective actions The manufacturer shall ensure by means of procedures, documented in the FPC manual, that the materials (raw materials, packaging, finished products) that do not conform to the specified requirements are clearly identified and/or segregated to prevent their use or despatch. The non-conforming material may be reworked to meet the specifications, reclassified or rejected and discarded, with a corrective action described and recorded in a non-conformity report. 5.4.4 Management and personnel The management activities to ensure that all of the above requirements operate shall be described in the manual. The manufacturer shall ensure that all personnel involved in the process receive the appropriate training to perform their duties. Where appropriate, all educational and training activities shall be recorded to prove the personnel qualification. The job description and the responsibilities of the operatives shall be given in the FPC manual. 6 Classification and designation The liquid-applied water impermeable products are classified into one of the three types, according to the definitions given in Clause 3: CM
