4.1.5 Surface finish Surface finish shall extend uniformly to the edges of a cladding slab or a tile. Surface after its finishing shall have a regular appearance as a function of the finishing process and shall be worked to meet the declared surface finish. This should be established on the samples of a cladding slab or a tile submitted beforehand by the manufacturer to the purchaser. EXAMPLE Surface finishes of a cladding slab or a tile include: − fine ground surfaces, obtained, e.g. by means of a grinding disk of grain size F 220; − matte finished surfaces, obtained, e.g. by means of a polishing disk with grain size F 400; − highly polished surfaces, obtained, e.g. by means of a polishing disk or felt. 4.2 Physical and mechanical characteristics 4.2.1 General The characteristics of the cladding slabs or tiles in 4.2.2 to 4.2.12 shall be declared when these products are subject to regulatory requirements and may be declared otherwise with reference to intended end use conditions. Contractual specifications may be used to establish reference values, e.g. stated in design or manufacturer’s data sheet, due account being taken of any regulatory requirements applicable. 4.2.2 Visual appearance This characteristic of a cladding slab or a tile shall be declared. The colour, surface finish and brightness of the agglomerated stone, which a cladding slab or a tile is made of, shall be identified visually according to Annex C, e.g. by a range of samples selected in agreement between manufacturer and purchaser. Any visual variations, e.g. inclusions and veins, are permissible provided that they are characteristic of the relevant type of agglomerated stone and provided that they do not adversely affect the performances of the cladding slabs or tiles. SIST EN 15286:2013

A cladding slab or a tile made of an agglomerated stone, which does not comply with the provisions a) and b) given above and having an intended use subject to the reaction to fire regulatory requirements shall be classified in accordance with EN 13501-1 after being tested in accordance with the test standards given therein, including mounting and fixings in accordance with EN 13823. 4.2.4 Apparent density and water absorption
The values for apparent density and water absorption shall be declared when a cladding slab or a tile is fixed (glued) by an adhesive or mortar and is intended to be used in a location subject to water contact. They shall be determined according to EN 14617-1 and the results expressed accordingly. 4.2.5 Flexural tensile strength The value for flexural tensile (bending) strength of a cladding slab or a tile shall be declared when required. The flexural tensile strength shall be determined using the test method in EN 14617-2 and the results expressed accordingly. In case of the textured upper face cladding slabs and tiles, the textured surface shall be prepared by grinding until fully flat or use flat samples of the same material with the minimum thickness dmin (see Figure 2). 4.2.6 Thermal conductivity Where a cladding slab or a tile is fixed (glued) by adhesive or mortar and subject to regulatory requirements the value for thermal conductivity shall be declared. Thermal conductivity shall be based on the apparent density value, determined using the test method indicated in 4.2.4. This value shall be used to calculate the thermal conductivity according to EN ISO 10456. Thermal conductivity may also be obtained by testing in accordance with EN ISO 13787 and the results expressed in W/(m·K) rounded to the first decimal place. 4.2.7 Thermal shock resistance Where subject to regulatory requirements or where a cladding slab or a tile is intended to be used subject to critical thermal cycles, the value for thermal shock resistance shall be declared. The thermal shock resistance shall be determined using the test method in EN 14617-6 and the results expressed accordingly.

6 Evaluation of conformity 6.1 General rules The compliance of agglomerated stone cladding slabs and tiles with the requirements of this standard and with the declared values (including classes) shall be demonstrated by:  Initial Type Testing (ITT);  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 product. For the purposes of testing, the 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 the same characteristics for all products within that same family. A product may be in different product families for different characteristics. 6.2 Initial Type Testing – Type Testing 6.2.1 General Initial Type Testing and Type Testing shall be performed to demonstrate compliance with this European Standard. All essential characteristics, in bold letters in Table 4, for which the manufacturer declares performances, are subject to Initial Type Testing. In addition, the need to perform Type Tests applies to all other characteristics included in a standard 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. NOTE Same system of attestation of conformity means testing by an independent third party for products covered by attestation of conformity system 1 and 3. SIST EN 15286:2013

6.2.3 Test reports All type tests, and/or initial type tests and their results 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 cladding slabs or tiles 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 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 production control system documentation shall ensure a common understanding of conformity evaluation and enable the achievement of the required product 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 compliance of the product with this European Standard. 6.3.2 Requirements 6.3.2.1 General The manufacturer is responsible for organising the effective implementation of the FPC system. Tasks and responsibilities in the production control organisation 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 conformity, shall be defined. This applies in particular to personnel that needs to initiate actions preventing product non-conformities from occurring, actions in case of non-conformities and to identify and register product conformity problems. Personnel performing work affecting product 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. 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 conformity of the product. 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; SIST EN 15286:2013

Individual products, product batches or packages shall be identifiable and traceable with regard to their production origin. The manufacturer shall have written procedures ensuring that processes related to affixing traceability codes and/or markings are inspected regularly. SIST EN 15286:2013

Production control operations include some or all of the following operations: a) the specification and verification of raw materials and constituents; b) the controls and tests to be carried out during manufacture according to a frequency laid down; c) the verification
