This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports basic requirements fo

26、r construction works of the EU Construction Products Regulation (Regulation (EU) No 305/2011). It also takes into account the general rules for reinforced and unreinforced masonry in Eurocode 6. For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document

27、. The most significant changes compared to the previous edition include: a) implementation of new regulatory (CPR) terminology where relevant; b) new subclause 5.4.2.2 on Flexural bond strength (deriving from Finnish legal query); c) revised clauses on Assessment and verification of constancy of per

28、formance (AVCP); d) new explanatory note added to tabulated values in Annex C; e) new annex with indicative frequencies on testing for factory production control (informative); f) revised Annex ZA (informative); g) some minor editorial changes. No changes to existing technical classes and/or thresho

32、 United Kingdom. DIN EN 998-2:2017-02 EN 998-2:2016 (E) 6 Introduction The characteristics required of a mortar are related to its use. They are considered in two groups, namely those relating to the fresh, unhardened mortar and those to the hardened mortar. DIN EN 998-2:2017-02 EN 998-2:2016 (E) 7

33、1 Scope This European Standard specifies requirements for factory-made masonry mortars (bedding, jointing and pointing) for use in masonry walls, columns and partitions (e.g. facing and rendered masonry, load bearing or non-load bearing masonry structures for buildings and civil engineering works).

34、This European Standard defines for fresh mortar the performance related to workable life, chloride content, air content, density and correction time (for thin-layer mortar only). For hardened mortar it defines, e.g. performance related to compressive strength, bond strength, density measured accordi

35、ng to the corresponding test methods contained in separate European Standards. This European Standard provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is in

36、cluded. This European Standard covers masonry mortars defined in Clause 3 with the exception of site made mortar. However, this European Standard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site made mortar. 2 Normative
