4 CUAP 06.02/13 Version January 2012 Page 4 of 19 1 Scope of the CUAP 1.1. Definition of the construction product The products are blind rivets made of metal. The blind rivets are normally made of carbon steel, stainless steel or aluminium. For special applications parts of the blind rivets can be made of special alloys. Samples of blind rivets and a corresponding connection are shown in Annex 1. The blind rivets and the corresponding connections are subject to tension and/or shear forces. Possible failure modes of connections made with blind rivets are described in Annex 1. The assessment of the load-bearing capacity of the blind rivets and the corresponding connections are part of the ETA request. 1.2 Intended use of the construction product The blind rivets are intended to be used for fastening metal sheeting to metal substructures. The sheeting can either be used as wall or roof cladding or as load bearing wall and roof element. The blind rivets can also be used for the fastening of other thin gauge metal members. The intended use comprises blind rivets and connections for indoor and outdoor applications. Blind rivets which are intended to be used in external environments with high or very high corrosion category are usually made of stainless steel or aluminium. Furthermore the intended use comprises connections with predominantly static loads (e.g. wind loads, dead loads). 1.3 Assumed working life of the construction product The provisions and the verification and assessment methods included or referred to in this CUAP have been written based upon the assumed working life of the blind rivets for the intended use of 25 years when installed in the works or 50 years if the blind rivets are not accessible after installation and they are sufficient protected against corrosion (e. g. made of stainless steel). These provisions are based upon the current state of the art and the available knowledge and experience. "Assumed working life" means that, when an assessment following the CUAP provisions is made, and when this working life has elapsed, the real working life may be, in normal use conditions, considerably longer without major degradation affecting the Essential Requirements. 1 The indications given as to the working life of the construction product cannot be interpreted as a guarantee given by the product manufacturer or his representative or the approval body issuing the ETA, but are regarded only as a means for choosing the appropriate products in relation to the expected economically reasonable working life of the works (see of the Interpretative Documents). 1.4 Terminology Common terms relating to the Construction Products Directive For the meaning of these terms see EOTA document "Common terms used in Guidelines for European technical approval" published on the EOTA website. 1.5 Procedure in the case of a significant deviation from the CUAP In cases in which this CUAP is intended to be used for another similar product and/or intended use but not complete or fully applicable in all aspects, the approval body concerned shall 1 The real working life of a product incorporated in a specific works depends on the environmental conditions to which that works is subject and the particular conditions of the design, execution, use and maintenance of that works. Therefore, it cannot be excluded that there are cases in which the real working life of the product may also be shorter than the assumed working life.

The procedure of Art. 9.2 of the CPD and section 3.2 of the Common Procedural Rules will then be based on the supplemented or modified CUAP. 2 Assessment of fitness for use 2.1 Meaning of "fitness for use" "Fitness for (the intended) use" of a construction product means that the product has such characteristics that the works in which it is to be incorporated can, if properly designed and built, 1. satisfy the Essential Requirements when and where such works are subject to regulations containing such requirements (CPD Art. 2.1) and 2. be fit for their intended use, account being taken of economy, and in this connection satisfy the Essential Requirements for an economically reasonable working life, if normally maintained (see CPD Annex I, sentence 1 and 2). 2.2 Elements of the assessment of fitness for use The assessment of the fitness of a construction product for its intended use includes: the identification of the characteristics of the product which are relevant to its fitness for use (in the following referred to as "regulatory characteristics"); the establishment of methods for the verification and assessment of the regulatory product characteristics and the expression of the respective product performances; the identification of such regulatory characteristics to which the option "No Performance Determined" applies for the reason that in one or more Member States they are not relevant for the fulfilment of the requirements applicable to the works; the identification of such regulatory characteristics for which limit values (threshold values) have to be respected for technical reasons.

6 CUAP 06.02/13 Version January 2012 Page 6 of Relationship of requirements to the product characteristics and methods of verification and assessment The product characteristics, methods of verification and assessment criteria which are relevant for the fitness of blind rivets for the intended use referred to in 1.2 are given in Table 1. Table 1: Product characteristics and methods of verification and assessment Nr Product characteristic Option "No Performance Determined" Method of verification and assessment Expression of product performance (1) (2) (3) (4) (5) Essential Requirement 1: Mechanical resistance and stability 1 Shear resistance of connection no V R,k [kn] V R,d [kn] 2 Tension resistance of connection no N R,k [kn] N R,d [kn] 3 Shear resistance of blind rivet no pass / fail 4 Tension resistance of blind rivet no pass / fail 5 Design resistance in case of combined tension and shear forces (interaction) no pass / fail Essential Requirement 2: Safety in case of fire 6 Reaction to fire yes NPD or performance class not relevant Essential Requirement 3: Hygiene, health and environment Essential Requirement 4: Safety in use 7 Shear resistance of connection no V R,k [kn] V R,d [kn] 8 Tension resistance of connection no N R,k [kn] N R,d [kn] 9 Design resistance in case of combined tension and shear forces (interaction) no pass / fail not relevant not relevant Essential Requirement 5: Protection against noise Essential Requirement 6: Energy economy and heat retention General aspects relating to fitness for use ** 10 Durability yes NPD or acc. to EN ; EN *) Aspects of durability and economy of the works (see CPD Annex 1, sentence 1 and 2) which are not dealt with under Essential Requirements 1 to 6. Such aspects are also referred to as "serviceability". **) The verification methods, which concern the Essential Requirements ER 1 and ER 4, are identical because they refer to the determination of the shear resistance and the tension resistance of the connections with blind rivets.

7 CUAP 06.02/13 Version January 2012 Page 7 of Product characteristics which are relevant for the fitness for use Shear resistance of the connection Method of verification General The remaining part of the mandrel after setting of the blind rivets shall be removed before starting the tests unless the mandrel is regular part of the load-bearing system such as it is for triple claw blind rivets. If the mandrel is not removed, the characteristic shear resistance obtained from the tests is only valid for the tested combination of sheeting thickness t I and substructure thickness t II and should not be used for combinations with larger thicknesses of both sheeting thickness t I and substructure thickness t II. Special care should be taken on the durability of the mandrel (see 2.4.7) Single layer shear tests At least 10 shear tests with single sheet layers shall be carried out for each relevant combination of sheeting thickness t I and substructure thickness t II. The test load shall be increased until shear failure of the blind rivet or local bearing deformation (hole elongation) of the sheeting or the substructure occurs. The deformation capacity up to maximum load shall be at least 0.5 mm. The maximum load which shall be taken into account in order to determine the relevant characteristic resistance is the maximum load which corresponds to a deformation capacity within a range from 0.5 mm 3.0 mm. The predrill diameter, the load-deformation curves and the respective failure modes as well as the material properties of the sheeting, the substructure and the blind rivet and used for the tests shall be documented in the test report. Furthermore the failure loads shall be given in the test report. The material properties should be documented by means of inspection documents 3.1 according to EN 10204:2004. The material properties have to correspond to the material specifications given by the manufacturer. An example for the test setup is shown in Annex Four layer shear tests Four layer shear tests are optional tests. If they are carried out the following applies: At least 10 shear tests with 4 sheet layers shall be carried out for each relevant substructure thickness t II. The test load shall be increased until shear failure of the blind rivet or local bearing deformation (hole elongation) of the sheeting or failure of the substructure occurs. The deformation capacity up to maximum load shall be at least 0.5 mm. The maximum load which shall be taken into account in order to determine the relevant characteristic resistance is the maximum load which corresponds to a deformation capacity within a range from 0.5 mm 3.0 mm. The predrill diameter, the load-deformation curves and the respective failure modes as well as the material properties of the sheeting, the substructure and the blind rivet used for the tests shall be documented in the test report. Furthermore the failure loads shall be given in the test report. The material properties should be documented by means of inspection documents 3.1 according to EN 10204:2004. The material properties have to correspond to the material specifications given by the manufacturer. The tensile strength of the material of the component with the thickness t I (sheeting) should be at the upper limit range according to the relevant product standard (e. g. EN 10346:2009). The maximum possible thickness of the sheeting (4 x t I ) shall be used. This is the maximum thickness for sheeting fastenings where longitudinal and transverse lap joints coincide Method of assessing and judging Determination of characteristic shear resistance The results of the tests according to and (failure loads or maximum loads) shall be multiplied by the following correction factor α which depends on the failure mode: - local bearing of sheeting: α = (R m,min /R m ) (t I,min /t I ) local bearing of metal substructure: α = (R m,min /R m ) (t II,min /t II ) failure of fastener: α = 1.0 with:

8 CUAP 06.02/13 Version January 2012 Page 8 of 19 R m,min = minimum tensile strength of the relevant metal components t I or t II according to the relevant product standard R m = tensile strength of the relevant metal components t I or t II used for the tests t I,min, t II,min = minimum thickness of the relevant components t I or t II according to the relevant product standard t I, t II = thickness of the relevant components t I or t II used for the tests The corrected test results shall be evaluated statistically (determination of 5% fractile, confidence level 75%). Generally a normal distribution can be assumed. The corrected and statistically evaluated test results (5% fractile) are the characteristic values V R,k of the shear resistance of the connection. V R,k shall not exceed the by the manufacturer guaranteed minimum shear resistance of the blind rivets Determination of design shear resistance The design values V R,d of the shear resistance are the characteristic values of the shear resistance according to divided by the recommended partial safety factor γ M = The recommended partial safety factor γ M should be used in cases where no value is given in national regulations of the Member State where the blind rivets are used Tension resistance of the connections Method of verification Static tensile tests At least 10 tensile tests shall be carried out for each relevant combination of sheeting thickness t I and substructure thickness t II. The test load shall be increased until failure of the connection. The predrill diameter, the respective failure modes as well as the material properties of the sheeting, the substructure and the rivet used for the tests shall be documented in the test report. Furthermore the failure loads shall be given in the test report. The material properties should be documented by means of inspection documents 3.1 according to EN 10204:2004. The material properties have to correspond to the material specifications given by the manufacturer. An example for the test setup is shown in Annex 2. It is possible to perform separate pullthrough tests and pull-out tests. In this case, the characteristic value of tension resistance for a given combination of sheeting thickness t I and substructure thickness t II is the minimum value of the pull-through resistance and the pull-out resistance, both determined according to Cyclic tensile tests Cyclic tensile tests are additional optional tests. If they are carried out the following applies: At least 5 cyclic tensile tests with a constant amplitude loading range from a minimum loading to maximum loading shall be carried out at 3 different load levels for each relevant sheeting thickness t I. The minimum loading should be close to zero, not exceeding 10% of the maximum loading. The loading frequency should be 5 Hz. The predrill diameter, the value of each of the 3 different load levels and the corresponding number of cycles until failure as well as the material properties of the sheeting, the substructure and the fastener used for the tests shall be documented in the test report. The material properties should be documented by means of inspection documents 3.1 according to EN 10204: The material properties have to correspond to the material specifications given by the manufacturer. An example for the test setup is shown in Annex 2. It is possible to perform separate pullthrough tests and pull-out tests. In this case, the characteristic value of tension resistance for a given combination of sheeting thickness t I and substructure thickness t II is the minimum value of the pull-through resistance and the pull-out resistance, both determined according to If separate pull-through tests and pull-out tests are performed, the results of cyclic pull-out tests are not relevant for blind rivets and closed end blind rivets according to Annex 1, but for triple claw blind rivets Method of assessing and judging Determination of characteristic tension resistance

9 CUAP 06.02/13 Version January 2012 Page 9 of 19 The test results of the tests according to and (failure loads or maximum loads) shall be multiplied by the following correction factor α which depends on the failure mode:

10 CUAP 06.02/13 Version January 2012 Page 10 of 19 Tests according to and : - failure of component I: α = (R m,min /R m ) (t I,min /t I ) failure of component II: α = (R m,min /R m ) (t II,min /t II ) failure of rivet: α = 1.0 with: R m,min = minimum tensile strength of the relevant metal components t I or t II according to the relevant product standard R m = tensile strength of the relevant metal components t I or t II used for the tests t I,min, t II,min = minimum thickness of the relevant components t I or t II according to the relevant product standard t I, t II = thickness of the relevant components t I or t II used for the tests The corrected test results shall be evaluated statistically (determination of 5% fractile, confidence level 75%). Generally a normal distribution can be assumed. The corrected and statistically evaluated test results (5% fractile) of the tests according to are the characteristic values of the static tensile resistance of the connection. The statistical evaluation of the results of additional optional cyclic tensile tests according to refers to the number of cycles until failure. On the basis of the 5% fractile curve of the number of cycles until failure at a certain load level, which shall be determined from the results of tests on 3 different load levels, the tensile resistance corresponding to 5000 cycles shall be determined. The result is the characteristic value of the tensile resistance for repeated wind loads. (Remark: Background information is given in the European Recommendations for the Design and Testing of Connections in Steel Sheeting and Sections, N 21, May 1983) The characteristic value of the cyclic tensile resistance for repeated wind loads should be determined as follows: If no cyclic tensile tests were carried out according to , the characteristic value is the characteristic value of the static tensile resistance multiplied by the following reduction factor α cycl : α cycl = 2/3 = 0.67 If separate pull-through tests and pull-out tests were performed, α cycl = 1.00 applies for the cyclic pull-out resistance of blind rivets and closed end blind rivets according to Annex 1, but not for triple claw blind rivets. If cyclic tensile tests were carried out according to , the characteristic value is the characteristic value of the static tensile resistance multiplied by the following reduction factor α cycl : α cycl = 1.5 x (char. cyclic tensile resistance/char. static tensile resistance) 1.0 (Remark: The factor 1.5 takes into account the different safety levels for fatigue design and design for predominantly static loads. α cycl is limited to 1.0.) The possibly required reduction of the pull-through resistance due to the position of the rivet shall be taken into account according to EN , section 8.3 (7) and Fig. 8.2 or EN , Table 8.3. The corrected and statistically evaluated test results (5% fractile) of the tests according to and where appropriate are the characteristic values of tension resistance N R,k of the connection. In the case of two values for N R,k the smaller value applies. N R,k shall not exceed the by the manufacturer guaranteed minimum tension resistance of the blind rivets Determination of design tension resistance The design values of the tension resistance are the characteristic values of the tension resistance according to divided by the recommended partial safety factor γ M = The recommended partial safety factor γ M should be used in cases where no value is given in national regulations of the Member State where the blind rivets are used.
