It supersedes BS EN 1341:2000 which is withdrawn. EN 1341: 2001 is a candidate “harmonized” European Standard and fully takes into account the re
4、quirements of the European Commission mandate M119 “Floorings”, given under the EU Construction Products Directive (89/106/EEC), and intended to lead to CE marking. The date of applicability of EN 1341:2001 as a “harmonized” European standard, i.e. the date after which this standard may be used for
5、CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. EN 1341:2001 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 1341:200
6、1 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the end of th
7、is co-existence period, the national standard(s) will be withdrawn. In the UK, there is no corresponding national standard. The UK participation in its preparation of EN 1341:2001 was entrusted to Technical Committee B/507, Paving units and kerbs, to Subcommittee B/507/2, Paving units and kerbs Natu

26、c) BSI EN 1341:2001 (E) 4 1 Scope This European Standard specifies the performance requirements and the corresponding test methods for all natural stone slabs, for external paving use. It provides for product marking and for the evaluation of conformity of the product to this European Standard. This
27、 European Standard covers also characteristics that are of importance to the trade. It does not cover internal flooring tiles or slabs nor does it cover the effect of de-icing salts (see clause 4.2). 2 Normative references This European Standard incorporates by dated or undated reference provisions
28、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 Standard only when incorporated in it by amend
29、ment or revision. For undated references, the latest edition of the publication referred to applies (including amendments).

The abrasive flow rate shall be verified by pouring the material from a height of approximately 100 mm into a pre-weighed rigid container with a smooth rim, of height (90 10) mm and of known volume
48、 when filled to the top, this shall be approximately 1 litres. As the container fills, the pourer shall be raised to maintain approximately 100 mm fall. When the container is filled, the top shall be struck off level and weighted to determine the mass of abrasive for a known volume, i.e. the density

The filled container shall be weighed and from the density determined above, the rate of abrasive flow can be verified as 2,5 litres per minute. The apparatus shall be calibrated against a reference of “Boulonnasie Marble“2) using the procedure in C.6 and the counterweight adjusted so that after 75 revolutions of the wheel in (60 3) s the length of the groove produce
