corrosion resistant diamond shaped mesh to provide a key for plastering (see Figure 3a) 3.1.2 expanded corrugated metal lath
corrosion resistant diamond mesh to provide extra stiffness (see Figure 3b) 3.1.3 expanded ribbed lath
corrosion resistant mesh formed by expanding with integral solid ribs of at least 7 mm height to provide extra stiff-ness (see Figure 4) 3.1.4 expanded mini ribbed lath corrosion resistant mesh formed by expanding with integral solid ribs between 4 mm and 7 mm height (see Figure 4) 3.1.5 stainless steel ribbed lath stainless steel mesh with integral solid ribs of at least 7 mm height 3.1.6 paperbacked ribbed lath corrosion protected paperbacked mesh with integral ribs of at least 7 mm height 3.1.7 standard paperbacked wire lath corrosion resistant wire spot welded to form a square mesh to provide a key for plastering; between the horizontal and vertical wires a sheet of cardboard is positioned (see Figure 5) 3.1.8 reinforced paperbacked wire lath same as 3.1.7, but the reinforcing wires are thicker and less widely spaced in order to increase stiffness 3.1.9 high ribbed paperbacked wire lath same as 3.1.8, but with thicker wires to provide still greater stiffness

3.2.4 movement bead corrosion resistant profiled section connected with a flexible plastic extrusion capable of a movement within the range of ± 1,5 mm of the internal plaster surface NOTE this section can also be fabricated from wire 3.2.5 corner movement bead corrosion resistant profiled section as 3.2.4, with a flexible plastic extrusion used for 90° inner corners (maximum movement ± 1,5 mm) 3.2.6 expansion bead corrosion resistant profiled section with a flexible extrusion capable of movement greater than ± 1,5 mm, i.e. to al-low for background movement which provides vertical and horizontal flexibility 3.2.7 corner expansion bead corrosion resistant profiled section as 3.2.6 to allow for background movement in 90° inner corners 3.2.8 depth gauge bead profiled section which can be set on plane surfaces to control the depth of plaster applied

See Table 1 for geometric profiles 4 Requirements 4.1 Fire behaviour 4.1.1 Reaction to fire When the intended use of metal lath and beads is for situations in building construction works where there is a risk of exposure to fire, metal lath and beads shall be classified A1 without the need of testing1 unless they have or-ganic coatings or flexible middle parts. In this case they shall be tested and classified in accordance with EN 13501-1. 4.1.2 Fire resistance Metal lath and beads can be used in walls, partitions and ceilings and encasement systems providing fire ratings. When required, the fire rating of the system shall be tested to EN 1364-1, EN 1364-2, EN 1365-1, EN 1365-3 and EN 1365-4 as appropriate and classified to EN 13501-2. 4.2 Requirements for lath 4.2.1 Material Lath shall be manufactured from the materials and finishes shown in Table 2. The corrosion resistant selected ma-terial and finish shall provide a satisfactory level of protection against corrosion under conditions of intended use, i.e. regional requirements. 4.2.2 Description a) Expanded lath, ribbed lath and wire lath shall be formed to provide the functional requirements of stiffness to span between supports or fixings and have aperture sizes to provide an efficient keying matrix for the plaster. Typical products meeting these requirements are given in Tables 3 and 4 and in Figures 3, 4 and 5 ; b) normal and stainless steel claylath are produced in open, half open and closed versions (see Figure 7). At least 60 % of the surface area shall be covered with clay.
1 According to Commission Decision 96/603/EC as amended.

NOTE The dimensions are for "clear aperture" not centre to centre of strands. 4.2.3.4 Standard paperbacked wire lath The wires shall have a minimum nominal equivalent diameter of 1,4 mm (see Figure 5 and Table 4). 4.2.3.5 Reinforced paperbacked wire lath Same as 4.2.3.4, but the reinforcing wires shall have a minimum nominal equivalent wire diameter of 3,0 mm spaced at distances not greater than 150 mm. The moment of inertia in the direction where increased stiffness is required shall be at least 10 mm4. 4.2.3.6 High ribbed paperbacked wire lath Same as 4.2.3.4 but the reinforcing wires shall have a minimum nominal equivalent wire diameter of 3,9 mm spaced at distances not greater than 150 mm. The moment of inertia in the direction where increased stiffness is required shall be at least 30 mm4. 4.2.3.7 Normal and stainless steel claylath For requirements, see Table 5 and Figure 7. The figure shows the open type. In half open and closed claylath the apertures between the crosses may be closed with fired clay.
