BRITISH SCAFFOLD STANDARD | BSEN 12811-2:2004 | PART 2 : INFORMATION ON MATERIAL |

***BS EN 12811-TEMPORARY WORKS EQUIPMENT*** *Part 2: Information on materials** BS EN 12811-2:2004 1. Scope • This European Standard provides guidance on where to find information on materials often used in temporary works. It draws attention to a number of points that a designer should take into account. • The information given is limited to commonly use steel, aluminium alloys, cast iron, timber and timber based materials. • Requirements are also given for welding, for limiting corrosion and other deterioration. • It is limited to the selection of types and grades of material from standards, which are either international or European Standards. 2. Normative references 3. General *Selection of materials *Characteristic values *Inspection documents - accordance with EN 10204. *Effects of fabrication 4 Steel 5 Cast iron 6 Aluminium alloys 7 Timber and timber based materials *Materials specified in ENV 1995-1-1 shall be used. For solid timber coniferous or poplar wood with a minimum strength class C16 in accordance with EN 338 shall be used. The glue used for glued laminated timber and timber based materials shall meet the requirements of Type I of EN 301. *Wood-based materials (plywood, particleboard, fibreboard) • Construction of platforms: The top layer shall have a minimum thickness of 0,8 mm, the intermediate ones may have 2,0 mm maximum thickness, measured in final condition. The top layer in uncoated condition shall be free of defects like loose knots, fissures and splits. 8 Protection against corrosion and deterioration Ferrous metal products Class Corrosion protection C1 Protective paint in accordance with EN ISO 12944 part 1 to 8. C2 Hot dip galvanised coatings and similar methods C3 Hot dip galvanised in accordance with EN ISO 1461 T Aluminium alloys In normal areas of use, aluminium alloys do not require surface protection. Information on corrosion protection for structures in exposed environment, e.g. near to the sea, chemical works or where electrolytic action can occur, is given in ENV 1999-1-1. Plywood for scaffold decks • Plywood shall be protected against wood damaging fungus (Basidiomycetes) during fabrication with a suitable wood preserver if the plywood is not of high resistance. • The edges of plywood panels shall be equipped with a permanently elastic sealing. • This sealing also shall be pervious to the diffusion of vapour. For example acrylic-latex layers may be used; minimum thickness of the layer: 30 m. 9 Welding Welding shall be carried out in accordance with EN 729-1. *Annex A (Informative) Information taken from other material and design standards A.1 — Steel - Nominal values for tubes and hollow sections A.2 — Steel - Nominal values for profiles, sheet and strip products A.3 — Aluminium - Nominal values for plates and sheets (taken from EN 485-2) A.4 — Aluminium - Nominal values for extruded tubes and extruded profiles (taken from EN 755-2) A.5 — Structural timber A.6 — Glued laminated timber BRITISH SCAFFOLD STANDARD *BSEN 12811 SCAFFOLD STANDARD PART 2 *BRITISH SCAFFOLDING STANDARD KE BAARE ME PURA INFORMATION *GULF ME SCAFFOLD KA KONSA STANDARD HAI *GULF KELIYE SCAFFOLD STANDARD *SCAFFOLDING BRITISH STANDARD *SCAFFOLD STANDARD *SYSTEM SCAFFOLDING *INFORMATION ON MATERIAL *SCAFFOLDING KIS STANDARD SE BANANA HAI *SCAFFOLDING MATERIAL British scaffold standard BSEN 12811 Part 2 BSEN 12811 scaffolding standard explained British scaffolding standards full information Gulf scaffold standard Scaffolding standards in Gulf countries Scaffolding British standard Scaffolding international standards EN / BS / OSHA Scaffold standard and regulations System scaffolding explained Scaffolding tube standards and specifications Scaffolding material information Scaffolding tube material specification Scaffolding kis standard se banana hai Scaffolding steel tube grade and size Scaffolding tube and fitting standard British standard for scaffolding tube Scaffolding material testing and inspection Scaffolding safe working standard British vs Gulf scaffolding standards Scaffolding EN 12811 explained #British #scaffolding #standard #scaffolding #training #standard #workatheight #guidelinesvs    • BRITISH SCAFFOLDING STANDARD | BSEN 12810-...      • INDIAN SCAFFOLD STANDARD | IS 3696 - SAFET...      • SCAFFOLDING TRAINING INSTITUTE IN INDIA | ...      • GOLDEN RULES FOR WORK AT HEIGHT SAFETY | W...      • SCAFFOLDING INTERVIEW QUESTIONS & ANSWERS ...      • GIN WHEEL & ROPE🪢|| PULLEY & ROPE || SPECI...      • CUPLOCK SCAFFOLD | CUPLOCK SCAFFOLDING COM...      • CISRS SCAFFOLDING SUPERVISOR TRAINING SYLL...      • Hanging scaffold || Suspended Scaffold || ...      • OSHA SCAFFOLDING TRAINING||SYLLABUS||SCAFF...      • SCAFFOLD COUPLERS/ CLAMPS CAPACITY#मचान कप...      • TYPES OF SCAFFOLD COUPLERS/CLAMPS ||SCAFFO...
