Metal beads and feature profiles, depending upon their material and type, can be featured without decoration, decorated or finished with jointing compounds to receive decoration. It covers the following performance characteristics: reaction to fire and flexural strength (bending behaviour) to be measured according to the corresponding European test methods. It provides for the evaluation of conformity of the product to this EN. This European 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 references The following referenced documents are indispensable for the application of this document.

They can be painted to provide protection, as undercoat for further decoration and to provide adequate adhesion for jointing materials. 4.6.2 Movement and expansion beads 4.6.2.1 Movement beads Movement beads shall provide the maximum differential movement stated by the manufacturer without damage. When determined in accordance with 5.6, this shall be at least 52+− mm and shall apply in both length and width directions. 4.6.2.2 Expansion beads Expansion beads shall provide the maximum differential movement stated by the manufacturer without damage. When determined in accordance with 5.6, this shall be at least ± 3 mm. 4.7 Dimensions and tolerances 4.7.1 General The nominal dimensions of beads and feature profiles shall be declared by the producer. Significant tolerances, other than those given in Table 2, shall also be declared by the producer.

The uncoated steel strip shall have a minimum thickness of 0,35 mm for galvanized and AZ/ZA coated steel and 0,4 mm for aluminium. The uncoated steel strip is calculated as nominal thickness minus tolerance and thickness of the protective coating. The thickness of the coating shall be obtained from EN 10326 or EN 10327, when appropriate. 4.7.3 Length The length shall be measured as described in 5.2.2 and compared with the nominal length. The tolerance shall be for beads ± 10 mm and for feature profiles 05− mm. 4.7.4 Straightness The straightness shall be measured as described in 5.2.3. It shall not be more than:  L/400 for angle beads;  L/600 for feature beads

is the length. 4.7.5 Beads The dimensions and angles of beads shall be measured as described in 5.3 and compared with the nominal dimension stated by the producer. See Table 2. 4.7.6 Feature profiles The cross sections of feature profiles are not dimensionally defined as they vary widely depending upon the decorative and aesthetic considerations. Manufacturers shall supply, on request, a dimensioned drawing of the cross section to enable design work to take place. When dimensions are measured in accordance with the method given in 5.3 the tolerance shall be ± 5 % on any individual measurement. 4.7.7 Wing width The minimum width of wings shall be measured as described in 5.4 and compared with the nominal dimensions stated by the producer. Examples of minimum wing widths are:  18 mm for angle bead;  20 mm for edge bead;  20 mm for feature bead;  18 mm for stop bead. 4.7.8 Wing open area The open area of each wing shall be determined as described in 5.5 and compared with the nominal percentage open area stated by the producer. The open area of each wing shall not be less than 5 % when determined as described in 5.5. 5 Test methods 5.1 Sampling Testing requires three specimens of each type of bead or feature profile on which tests 5.2 to 5.8 shall be applied, where appropriate, to the product. 5.2 Dimensional measurements 5.2.1 Thickness 5.2.1.1 Principle The distance between the two faces is measured in three separate positions per specimen. 5.2.1.2 Apparatus A micrometer permitting a reading to 0,01 mm.
