31、S EN 14496:2017EN 14496:2017 (E) 5 1 Scope This European Standard specifies the characteristics and performances of gypsum based adhesives which are composed of gypsum plasters defined in EN 13279-1 and of additives. These adhesives are used for fixing to walls and partitions, gypsum board thermal/a

32、coustic insulation composite panels according to EN 13950, gypsum plasterboard linings according to EN 520, gypsum boards with mat reinforcement according to EN 15283-1, gypsum fibre boards according to EN 15283-2 and other suitable products as reprocessed boards according to EN 14190 and cornices a

33、ccording to EN 14209. They assist in the construction of systems which provide thermal and acoustic performance. It covers the following performance characteristics: reaction to fire, fire resistance and bond strength to be measured according to the corresponding European test methods. It provides t

34、he assessment and verification of constancy of performance of the products.” This standard covers also additional technical characteristics that are of importance for the use and acceptance of the product by the construction Industry and the reference tests for these characteristics. 2 Normative ref

39、Requirements 4.1 Fire behaviour 4.1.1 Reaction to fire Gypsum building plaster is the main component of gypsum based adhesives. Therefore, gypsum based adhesives are classified A.1 (no contribution to fire) without testing when they contain less than 1 % by weight or volume (whichever is the more on

40、erous) of organic material (Commission Decision 96/603/EEC as amended). If they contain 1 % or more by weight or volume of organic material, they shall be determined and classified in accordance with EN 13501-1. When testing in EN 13823 is required, gypsum based adhesives shall be tested in their en

41、d use conditions. 4.1.2 Fire resistance NOTE Resistance to fire is a characteristic dependant on an assembled system and not of the product in isolation. When required, the fire resistance of a system including gypsum based adhesives for thermal/acoustic insulation composite panels shall be determin

42、ed and classified according to EN 13501-2. 4.2 Bond strength The bond strength of the adhesive determined as described in 5.6 shall not be less than 0,06 MPa. 4.3 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes cont

43、ent, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering

44、European and national provisions on dangerous substances is available at the Growth website on EUROPA accessed through: https:/ec.europa.eu/growth/tools-databases/cp-ds 4.4 Calcium sulfate content The calcium sulfate content of the powder as a percentage by mass of the product shall not be less than

45、 30 % when calculated from the result of the test carried out in accordance with 5.2. 4.5 End of utilization time The end of utilization time is determined as described in 5.5 shall be greater than the time declared by the producer. 5 Test methods 5.1 General This standard describes the specific tes

46、t methods for gypsum based adhesives for thermal/acoustic insulation composite panels and gypsum boards. BS EN 14496:2017EN 14496:2017 (E) 7 General conditions of tests as well as test method which are common to gypsum plaster and gypsum based adhesives are described in EN 13279-2. Those test method

47、s which enable the requirements of this European Standard to be evaluated are given below; test methods for other properties, for example particle size, may be used by agreement. 5.2 Determination of the calcium sulfate content Test method is described in 4.2 of EN 13279-2:2014. 5.3 Determination of

48、 the water/adhesive ratio Test method is described in EN 13279-2:2014, 4.3.2. 5.4 Preparation of the paste for the tests The paste used for the tests and for the preparation of test pieces is prepared as described in EN 13279-2:2014, 4.3.2. 5.5 Determination of the end of utilization time 5.5.1 Prin

49、ciple The depth of penetration of the conical penetrator (cone) into a gypsum based adhesive/water paste as the set progresses shall be measured. 5.5.2 Apparatus a) Vicat apparatus: see EN 13279-2:2014, Figures 2 and 3; b) conical penetrator (cone): see EN 13279-2:2014, Figure 4; c) glass plate: about 150 mm long and 150 mm wide; d) Vicat ring: see EN 13279-2:2014, 4.3.2.3 item b); e) straight edge:140 mm length; f) chronometer; g) mixer and paddle: see EN 196-1:2016, 4.4 (description in Annex A). 5.5.3 Procedure The Vicat ring shall be placed
