Bitumen and bituminous binders. Determination of mixing stability with cement of bituminous emulsionsBS EN 12848: 2009, BS 2000 486: 2009 Bitumen and bituminous binders. Determination of mixing stability with cement of bituminous emulsions BS EN 12848 is the European Standard which specifies a method for the determination of mixing stability of bituminous emulsions with cement. It applies to overstabilized cationic bituminous emulsions and to slow setting and overstabilized anionic bituminous emulsions. The use of BS EN 12848 can involve hazardous

Light hazard from operation microscopes used in ocular surgery

A metallic reference spike has been defined

Problems of flood-flow measurement

Examples of appliances that are within the scope of this standard are:
