BS 6510:2010 pdf download – Steel-framed windows and glazed doors – Specifcation 6.2 Frame joints Welded frame joints shall have signifcant surfaces dressed square and fat. NOTE 1 Signifcant surfaces are those visible after installation when windows and doors are closed and viewed from a distance of 1 m, unless specifed otherwise by the purchaser. When tested for bending resistance and torsional strength (see Note 2), sample welded corner pieces, selected at intervals appropriate to production volume and batch quantity (see Note 3), shall have their parent metal tear before failure of the welded joint. NOTE 2 The test methods given in BS 4872‑1:1982, Clause 18 and Clause 19, or BS EN 287‑1:2004, Clause 6, or adaptations thereof, would be appropriate. NOTE 3 Welded corner pieces tested at the start of each new production order, and at least once weekly per welding machine thereafter, would be an acceptable sampling rule for small batch production. Joints effected by mechanical means, such as cleating and screwing, shall be sealed. When tee glazing bars of solid hot‑rolled steel profle are incorporated, they shall be riveted and/or welded to frames, and shall interlock with rigid joints displaying face gaps of no more than 1 mm. 6.3 Weatherseals Weatherseals shall be clipped, clamped, or secured by adhesives. 6.4 Hardware Double‑point or multi‑point fasteners shall be ftted on opening windows over 1 200 mm long or 1 500 mm high. 7 Protective fnishes 7.1 Rust-protection Frames and ancillary profles shall be rust‑protected using one of the following methods, or otherwise treated to provide rust protection of demonstrably equivalent or superior performance: a) hot dip galvanizing after fabrication in accordance with BS EN ISO 1461; or b) hot dip galvanizing before cold‑forming in accordance with BS EN 10346:2009, coating designation Z200 or Z275; or c) hot melt zinc spraying in accordance with BS EN ISO 2063; or d) stoved epoxy zinc priming in accordance with BS EN ISO 12944 suitable for moderate environments and always over‑coated with a colour fnish. NOTE One way of demonstrating “equivalent or superior performance” could be to compare specimen sample pieces of conventionally protected steel and of the proposed new fnish, subjecting both simultaneously to a BS EN 1670:2007, grade 4 (240 h) salt spray test. 7.2 Colour-coating Frames and ancillary profles shall be colourcoated, when required, either: a) in accordance with either BS 6497 or BS EN 13438 with a paint thickness...
