ACCURATE, SAFE AND PERFECT FOR EVERYDAY USE BY CAREFUL PROFESSIONALS. DESIGNED BY MAUN TO GET THE JOB DONE. This method of testing is described in both BS8204-Part 1:2003 and BS8204-Part 2:2003. A 2m straight edge is used in both specifications. Ensuring a surface is even and smooth once concrete finishing is completed is a vital task for construction professionals eager to leave an accurate and neat job.

A method of assessing flatness was given in CP 204: 1965 In-situ floor finishes (metric edition 1970) which used a 10ft (~3m) straight edge that was not set directly on the slab but on feet. No apparatus description was given, nor methodology to cover its use or sampling criteria. The idea was to assess unevenness below the temporary datum of the straight edge as a +/- measurement. The straight edge board is suitable for levelling and ruling off plaster and render. Also ideal for screed and floor work. SpecificationThe rolling straight edge is shipped in 3 wooden cases with a total gross weight of 112kg.

Lovely looking straight edge, not used it yet as I intend to use it on a special job in France. Don't anticipate any problems great tool delivered in perfect condition. For a proposed revision of BS 8204 in 2003, a straight edge with feet was again suggested, which was intended to be more portable than the 3m straight edge. This consistedof a collapsible 3m long frame with a wire stretched to standard tension from which to measure the deviation was proposed. This method was rejected in favour of a 2m straight edge set on the slab and is the methodis adoptedin the currentBS 8204,BS EN 13670 Execution of concrete structures, the National Structural Concrete Specification and National Building Specification.If the rate of testing is not known, then we would recommend the following formula to calculate the minimum number of straight edge tests. The Rolling Straight edge measures depressions on the pavement surface on analogue scale 0-12mm + 0.25mm. The straight edge also has an odometer for accurate determination of distance travelled in units of 1 metre. The Rolling Straight edge is pushed at 1-2km/h and the number of irregularities, their length and distance from start, are recorded. The national specifications for surface regularity are then compared and the pavement accepted or rejected and or remedial work undertaken.
