EN 413-2:2016 (E) 4 European foreword This document (EN 413-2:2016) has been prepared by Technical Committee CEN/TC 51 “Cement and building limes”, the secretariat of which is held by NBN. 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of an identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by February 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 413-2:2005. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 413, Masonry cement, consists of the following parts: — Part 1: Composition, specifications and conformity criteria; — Part 2: Test methods. The main differences between this document and EN 413-2:2005 are: — updating of normative references; — revised guidance on the properties of gauzes used in the water retention test; — revised repeatability and reproducibility limits for setting time(Method B), water retention and air content (these revisions are based on a round-robin test programme instituted following the introduction of a new class of Masonry cement MC 22,5 into EN 413-1). According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 413-2:2016 (E) 5 Introduction This European Standard includes additional test methods to those described in the EN 196 series, Methods of testing cement, that enable the performance of masonry cement to be assessed when used in mortar for bedding masonry units and for rendering and plastering. SIST EN 413-2:2017
EN 413-2:2016 (E) 6 1 Scope This European Standard describes reference and alternative test methods to be used when testing masonry cements to assess their conformity to EN 413-1. It gives the tests on fresh mortar for consistence, water retention and air content. In the event of a dispute, only the reference methods are used. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 196-1, Methods of testing cement - Part 1: Determination of strength EN 196-3:2005+A1:2008, Methods of testing cement - Part 3: Determination of setting times and soundness EN 459-2:2010, Building lime - Part 2: Test methods 3 General requirements for testing 3.1 Laboratory Unless specifically stated to the contrary, all the tests described in this document shall be carried out in a laboratory where the air temperature is maintained at (20 ± 2) °C and the relative humidity at not less than 50 %. 3.2 Manufacturing tolerances for test equipment 3.2.1 Dimensions Figures indicating the specified requirements for apparatus used in the tests described in this document shall include essential dimensions for which manufacturing tolerances are given. Unless otherwise stated, tolerance class m according to EN 22768-1 should be applied. NOTE Other dimensions are given for guidance. 3.2.2 Mass Specified masses shall have manufacturing tolerances within ± 1 % of the mass unless otherwise stated. 3.3 Tolerances for test equipment in use Tolerances applying to apparatus, which has been subjected to wear in use shall not exceed twice the corresponding manufacturing tolerance unless alternative requirements are specified. SIST EN 413-2:2017
EN 413-2:2016 (E) 7 3.4 Number of tests Where the test is one of a series subject to statistical control, determination of each property by a single test shall be the minimum required. Where the test is not part of a series subject to statistical control, two tests shall be performed to determine each property. 4 Determination of setting time 4.1 General The setting time is determined by observing the penetration of a needle into a cement paste of standard consistence until it reaches a specified value. The setting time is determined in accordance with either method A (4.2) or method B (4.3). Method B is the reference method. 4.2 Method A The setting time is determined in accordance with EN 196-3. NOTE Experience has shown that the method specified in EN 196–3, in which the specimens are tested under water, is not suitable for some masonry cements which have low clinker contents. 4.3 Method B 4.3.1 Test principle The equipment used and the specimen preparation procedures are as described in EN 196-3 but with the additional requirement for a room or a humidity cabinet of adequate size and maintained at (20 ± 1) °C and not less than 90 % relative humidity. 4.3.2 Initial setting time procedure Calibrate the Vicat apparatus with the needle, attached in advance of the test, by lowering the needle to rest on the base-plate to be used and adjusting the pointer to read zero on the scale. Raise the needle to the stand-by position. Fill a Vicat mould in accordance with EN 196-3:2005+A1:2008, 5.2.2 with paste of standard consistence mixed in accordance with EN 196-3:2005+A1:2008, 5.2.1 Place the filled mould and base-plate in the room or humidity cabinet and after a suitable time, position the mould and base-plate under the needle of the Vicat apparatus. Lower the needle gently until it is in contact with the paste. Pause in that position for between 1 s and 2 s in order to avoid initial velocity or forced acceleration of the moving parts. Then release the moving parts quickly and allow the needle to penetrate vertically into the paste. Read the scale when penetration has ceased, or 30 s after the release of the needle, whichever is the earlier. Record the scale reading, which indicates the distance between the end of the needle and the base-plate, together with the time from zero. Repeat the penetration on the same specimen at conveniently spaced positions, not less than 8 mm from the rim of the mould or 5mm from each other and at least 10 mm from the last penetration position, at conveniently spaced intervals of time, e.g. at 10 min intervals. Between penetrations keep the specimen in a room or humidity cabinet. Clean the Vicat needle immediately after each penetration. Retain the specimen if determination of the final setting time is to be made. SIST EN 413-2:2017
EN 413-2:2016 (E) 8 4.3.3 Report – initial setting time Report the elapsed time measured from zero to the time at which the distance between the needle and the base-plate is (6 ± 3) mm as the initial setting time of the cement to the nearest 5 min. If the initial setting time exceeds 6h determine the final setting time. 4.3.4 Final setting time procedure Invert the filled mould and follow the procedure described in EN 196-3:2005+A1:2008, 6.3 with the specimen held in the room or humidity cabinet at controlled humidity rather than under water. 4.3.5 Report – final setting time Report the elapsed time measured from zero to that at which the needle first penetrates only 0,5 mm into the specimen as the final setting time of the cement, to the nearest 15 min. 4.3.6 Repeatability and reproducibility The standard deviation of repeatability is 4 min for initial setting time and 7 min for final setting time. The standard deviation of reproducibility is 20 min for initial setting time and 24 min for final setting time. These precision data take into account uncertainty of measurement. 5 Preparation of standard mortar 5.1 Principle The properties of fresh mortar made with masonry cement are assessed on standard mortar pre

The setting time is determined in accordance with either method A (4.2) or method B (4.3). Method B is the reference method. 4.2 Method A The setting time is determined in accordance with EN 196-3. NOTE 1. Experience has shown that the method specified in EN 196–3, in which the specimens are tested under water, is not suitable for some masonry cements which have low clinker contents.

The consistence is measured using the plunger apparatus (see 5.2) as the reference method to achieve the required value of penetration. A flow table test (see 5.3) is allowed as an alternative to the plunger test but it is important that the flow table spread equivalent to the required value of penetration is established, using the same type of masonry cement as tha
