15、s“, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002. It

20、 of concrete as defined in prEN 1504-3 1under usual conditions. NOTE This method can only demonstrate that products are capable of being applied overhead. It cannot take into account the possible effects of the operatives skill on site. 2 Normative references This European Standard incorporates by d
21、ated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standa

26、substrate. After hardening, the pull-off strength is determined and taken for evaluation of overhead applicability. 5 Apparatus 5.1 Standard laboratory climate of (21 2) C and 60 % 10 % RH in accordance with EN 1542 (see annex A). 5.2 Concrete slabs for substrates MC (0,45) according to EN 1766, of

29、rding to EN 1542. 6 Test procedure Two concrete slabs (see 5.2), conditioned in accordance with the manufacturers instructions, are mounted with the grit blasted surfaces at the bottom. NOTE 1 The substrates can be supported by form work on two sides (see 5.4) to ensure the required uniform thicknes
30、s of repair mortar or concrete. The layer thickness shall be (20 2) mm for repair mortars up to 5 mm maximum particle size and (40 4) mm for repair materials with larger maximum particle sizes, unless recommended otherwise by the manufacturer. All materials shall be conditioned in the standard labor
31、atory climate (5.1) for a period of not less than 24 hours prior to mixing. The repair mortar or concrete is mixed according to the manufacturers instructions. If no particular instructions are given, the maximum water content should be applied in the case of CC and PCC. The repair mortar or concret
32、e is applied to the overhead surface of the prepared substrates according to the manufacturers instructions. NOTE 2 If required, the substrates may be pre-wetted and/or a bonding aid used. After application to the required layer thickness, the surface shall be finished with a steel float (5.5) to pr
33、ovide a smooth surface. The test specimens shall then be cured and stored according to annex A. After the cure periods (28 days for CC and PCC, 7 days for PC repair mortars see annex A) the pull off strength shall be determined for each slab according to EN 1542. 7 Test report The test report shall
34、include the following information: a) a reference to this European Standard, including the number, title and date of issue; b) name and address of the test laboratory; c) identification number and date of the test report; d) name and address of the manufacturer or supplier of the product(s); e) name
35、 and identification marks or batch number of the product(s); f) date of supply of the product(s); g) date of preparation of the test specimens and any deviation from the prescribed method of preparation, including whether it is a single or multi layer system and whether a bonding agent was used;EN 1
