According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 15361:2007 (E) 4 1 Scope This document specifies a pull-out test method for the verification of the applicability of the declared outer diameter of the transverse bars with corrosion protection coating φtot,g in the calculation of the anchorage capacity of transverse anchorage bars (see A.10.3 in prEN 12602:2006) in prefabricated reinforced components of autoclaved aerated concrete (AAC). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 678, Determination of the dry density of autoclaved aerated concrete EN 679, Determination of the compressive strength of autoclaved aerated concrete 3 Principle Pull-out tests on prismatic AAC test specimens including a longitudinal bar with a welded transverse anchorage bar with corrosion protection coating (see 5.3, type C) are made. The bearing stress in front of the welded transverse anchorage bar is calculated using the measured mean outer diameter φtot,m.of the welded transverse bar including the coating. For comparison, pull-out tests are made on otherwise alike test specimens, where the welded transverse bar is without corrosion protection coating, but has been treated with a thin layer of coating for elimination of bond (see 5.3 Type B). In this case the bearing stress in front of the transverse anchorage bar is calculated using the diameter of the transverse bar φt (without coating). In both cases the bond between the longitudinal bar and the AAC is eliminated using a proper method. NOTE Comparison of the determined bearing stresses will show if it is applicable to use the declared effective outer diameter of the transverse bar with corrosion protection coating, φtot,g, in the calculation of the anchorage capacity of the transverse anchorage bars. 4 Apparatus a) saw for cutting test specimens from reinforced AAC components without excessive heating, vibration or shock; b) testing machine or a loading device capable of applying a tension force at the required steady rate without shock and with an accuracy of 2 % of the ultimate pull-out force; c) rigid steel base plate with a central hole of 20 mm diameter to accommodate for the protruding longitudinal bar of the test specimen; d) intermediate layer of soft fibre board (thickness 10 mm to 20 mm, density 250 kg/m3 to 300 kg/m3, with a central hole of 20 mm diameter, to be inserted between the test specimen and the rigid steel plate; e) device for measuring the slip between the longitudinal reinforcing bar and the AAC to an accuracy of 1/100 mm and for recording the load-slip curve; SIST EN 15361:2008
EN 15361:2007 (E) 5 f) callipers capable of measuring the outer diameter of the transverse bar and the corrosion protection coating to an accuracy of 0,1 mm; g) ventilated drying oven, capable of maintaining a temperature of (105 ± 5) °C; h) balance for weighing test specimens to an accuracy of 0,1 %. 5 Test specimens 5.1 General The test specimens are obtained by cutting them e.g. from specially reinforced AAC components with
