In addition, instead of performing any actual testing, type testing may make use of: — generally accepted and/or conventional and/or standardized values, in the Clause 2 referenced standards, or in publications that are referred to in these standards; — standardized calculation methods and recognized calculation methods in the Clause 2 referenced standards, or in publications that are referred to in these standards; — assessment previously performed in accordance with the provisions of this standard (i.e. historic data), may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system (see note 1) on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question; — durability / conformity may be assessed indirectly by controlling the production processes according to this document. NOTE 1 AVCP systems were called Attestation of Conformity (AoC) systems under the EU Construction Products Directive (89/106/EEC). NOTE 2 Products CE marked in accordance with appropriate harmonized European specifications may be presumed to have the performances stated with the CE marking. NOTE 3 The assignment of tasks to the notified body(ies) and the manufacturer is shown in Tables ZA.2.1 to ZA.2.3. When actual testing is required then the type testing (TT) shall be undertaken on a sample representative of the product taken from direct production or a prototype, any plant and/ or line. 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 those same characteristics for all products within

FprEN 15681-2:2015 (E) 4 Foreword This document (FprEN 15681-2:2015) has been prepared by Technical Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by NBN. This document is currently submitted to the Unique Acceptance Procedure. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard consists of the following parts: — EN 15681-1 Glass in Building — Basic alumino silicate glass products — Part 1: Definitions and general physical and mechanical properties; — EN 15681-2 Glass in Building — Basic alumino silicate glass products — Part 2: Evaluation of conformity / Product standard. This document contains other aspects of importance for trade. Note: Due to fact that the EC has not yet been able to confirm the financial commitment for the New Approach Consultants’ work in 2015, there are currently no New Approach Consultants in place for 2015. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the European Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication. kSIST FprEN 15681-2:2015

5 Assessment and verification of constancy of performance – AVCP 5.1 General The compliance of basic alumino silicate glass products with the requirements of this standard and with the performances declared by the manufacturer in the declaration of performances shall be demonstrated by: 1. Determination of the product type; 2. Factory production control by the manufacturer, including product assessment; This shall include the following: a) Inspection of samples taken at the factory in accordance with a prescribed test plan; b) Initial inspection of the factory and of factory production control; c) Continuous surveillance and assessment of the factory production control. kSIST FprEN 15681-2:2015

FprEN 15681-2:2015 (E) 11 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). NOTE The assignment of tasks to the notified body(ies) and the manufacturer is shown in Table ZA.3. 5.2 Determination of the product type (see 5.1, 1) 5.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances. In addition, instead of performing any actual testing, type testing may make use of: — generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or in publications that are referred to in these standards; — standardised calculation methods and recognized calculation methods in the Clause 2 referenced standards, or in publications that are referred to in these standards; — assessment previously performed in accordance with the provisions of this standard (i.e. historic data), may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system (see note 1) on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question; — release of dangerous substances may be assessed indirectly by controlling the content of the substance concerned; — durability / conformity may be assessed indirectly by controlling the production processes according to this document< NOTE 1 AVCP systems were called Attestation of Conformity (AoC) systems under the EU Construction Products Directive (89/106/EEC). NOTE 2 Products CE marked in accordance with appropriate harmonized European specifications may be presumed to have the performances stated with the CE marking. NOTE 3 The assignment of tasks to the notified body(ies) and the manufacturer is shown in Table ZA.3. When actual testing is required then the type testing (TT) shall be undertaken on a sample representative of the product taken from direct production or a prototype, any plant and/ or line. 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 those same characteristics for all products within that same family NOTE 4 Products may be grouped in different families for different characteristics. Whenever a change occurs in the raw material or production process (subject to the definition of a family), which would change significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s). 5.2.2 Type testing of characteristic's performances All characteristics in 4.2.2 that are declared shall be subject to type testing in accordance with 5.2.1. kSIST FprEN 15681-2:2015
