FprEN 998-2:2010 (E) 5 Introduction The properties required of a mortar are related to its use. They are considered in two groups viz.: those relating to the fresh, unhardened mortar and those to the hardened mortar. To support the aim of achieving a performance-related standard, as far as practicable, the standard refers only to the properties of the product and not to its method of manufacture, except where this is unavoidable in the description of the characteristics of the product.

FprEN 998-2:2010 (E) 6 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 building and civil engineering). This European Standard defines for fresh mortars the performance related to workable life, chloride content, air content, density and correction time (for thin-layer mortars only). For hardened mortars it defines e.g. performances related to compressive strength, bond strength, density measured according to the corresponding test methods contained in separate European Standards. This European Standard provides for the evaluation of conformity of the product to this European Standard. The marking requirement for products covered by this European Standard is included. This European Standard covers masonry mortars defined in Clause 3 with the exception of site made mortars. However, this European Standard or part of this European Standard may be used in conjunction with codes of applications and national specifications covering site made mortars. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE Attention is drawn to the Commission Decision 96/603/EC, as amended, in which non-combustible masonry mortars containing not more than a mass or volume fraction of 1,0 % (whichever is the more onerous) of homogeneously distributed organic materials are classified as reaction to fire Class A1 without testing. 5.7 Mixing of mortar on site If certain types of mortar need specific site mixing equipment procedures or times, these shall be specified by the manufacturer. Mixing time is measured from the time when all constituents have been added. 6 Designation of masonry mortar The designation shall include the following, as relevant: number and date of issue of this European Standard; name of manufacturer; a code for or the date of production; type of mortar (3.2, 3.3 and 3.4); workable life (5.2.1); chloride content (5.2.2); air content (5.2.3); proportion of constituents (for prescribed mortars) and relationship to compressive strength or compressive strength class (5.3); compressive strength, or compressive strength class (for designed mortars) (5.4.1); bond strength (5.4.2); water absorption (5.4.3); water vapour permeability (5.4.4); density (5.4.5); thermal conductivity (5.4.6); durability (5.4.7); kSIST FprEN 998-2:2010
FprEN 998-2:2010 (E) 13 maximum aggregate grain size (5.5.2); correction time (5.5.3); reaction to fire (5.6). In the designation for a product, information about special qualities should be included when the mortar is intended for use in special construction. 7 Marking and labelling The designation (see Clause 6) or code identifying the designation shall be marked on the packaging, the delivery ticket or the manufacturer's data sheet or other information accompanying the product. NOTE For CE marking and labelling ZA.3 applies. ZA.3 requires the CE marking to be accompanied by the same information as required by this clause the requirements of this clause can be considered to have been met. 8 Evaluation of conformity 8.1 General Conformity assessment is needed to demonstrate, by Initial Type Testing, ITT (8.2), that the product complies with the requirements of this European Standard and that the performance declarations represent the true behaviour of the product and, by Factory Production Control, FPC (8.3), that the performance declarations based on initial type testing results remain valid for subsequent products. The manufacturer (or his agent) shall demonstrate the compliance for his product with the requirements of this European Standard by carrying out both ITT and FPC and is responsible for the product being in compliance with all the provisions. 8.2 Initial type testing, ITT After completion of the development of a new product type and before the commencement of the manufacture and the offering for sale, appropriate initial type testing shall be carried out that the properties predicted during the development meet the requirements of this European Standard and the values to be declared for the product. In the ITT-process a manufacturer may take in consideration already existing test results. For the verification of product characteristics requiring testing which is needed to be performed only during ITT, an individual manufacturer may use the ITT results obtained by someone else (another manufacturer) or carried out by industry to justify his own declaration of conformity regarding a product that is manufactured according to the same design and with raw materials, costituents and manufacturing methods of the same kind, provided that permission of the data owner is given, and the test is valid for both products. Where a manufacturer produces the same product on more than one production line or unit, or in more than one factory, there may be no need to repeat ITT for these different production lines or units (the manufacturer takes responsibility for ensuring that the products are indeed the same). 8.2.1 Sampling Sampling shall be carried out in accordance with Annex A. kSIST FprEN 998-2:2010
