Inspection schemes A.1 Finished product inspection The Table A.1 replaces item 2 of Table D.4 of EN 13369:2004. Table A.1 — Finished product inspection
Subject Method Purpose Frequency Product Testing 2a Critical dimensions Measuring according to 5.2 of EN 13369:2004 Conformity with the requirements of this standard and with the design specification One product / family / 5 production days One product/production day 2b Internal surface characteristics in case of pockets with keyed surfaces Visual inspection Roughness for shear resistance As for critical dimensions If treated after production: 1 element/roughening process/production day

Typical shapes of foundation elements B.1 Typology Precast concrete foundation elements dealt with in this European Standard can be distinguished in some principal types according to the following criteria: a) sockets constituting separate units (see Figure B.1); b) pocket foundation elements:  without footing (see Figure B.2);  with footing: with or without gentle slope (see Figure B.3);  with stiffeners (see Figure B.4); c) columns with integrated foundation elements (see Figure B.5).

a) for concrete column, with chamferred edges b) for concrete column, with straight edges Key 1 concrete column 2 reinforcement protruding from the socket 3 cast on site footing
c) for steel column Key 1 steel column 2 precast concrete socket 3 hole for steel bar 4 steel bar Figure B.1 — Examples of sockets

Choice of CE marking method Y.1 General The producer should choose to apply, for CE marking, one of the methods described in ZA.3, on the basis of the following conditions. Y.2 Method 1 The declaration of geometrical data and material properties as specified in ZA.3.2 may be applied when the following condition occurs:  off the shelf and catalogue products. Y.3 Method 2 The declaration of product properties determined following this standard and EN Eurocodes, as specified in ZA.3.3, should be applied when the following condition occurs:  precast product with product properties declared by the producer. Y.4 Method 3 The declaration of compliance with a given specification as specified in ZA.3.4 may be applied when the following condition occurs:  all other cases than Y.2 and Y.3.

Clauses of this European Standard addressing the provisions of the EU Construction Products Directive ZA.1 Scope and relevant characteristics This European standard has been prepared under the mandate M/100 "Precast Concrete Products"1 given to CEN by the European Commission and the European Free Trade Association. The clauses of this European standard shown in this Annex meet the requirements of the mandate given under the EU Construction Products Directive (89/106/EEC). Compliance with these clauses confers a presumption of fitness of the foundation elements covered by this annex for the intended uses indicated herein; reference shall be made to the information accompanying the CE marking.
