BS 4551:2005+A2:2013

Specifies methods of sampling preparation, physical testing and chemical analysis of mortars for bricklaying, plastering and rendering. The methods described are for the determination of parameters that have traditionally been used in the UK but which are neither defined, nor superseded, by BS EN 998-1, BS EN 998-2 or BS EN 1015 (all parts). Methods of interpretation of chemical analysis results are also described. The methods of test given are not intended to be applied to mortars containing high alumina cement or mortars whose principle binder is hydraulic lime.Cross References:BS 410-1ISO 3310-1BS 5404-1BS EN 933BS EN 1015-2 BS 6100-9BS EN ISO 3696BS 700BS 1881-124BS 3591 BS 4027BS 5224BS 6463BS 812-120BS EN 197BS EN 413-1BS EN 459BS EN 998-1BS EN 998-2BS EN 1015-1BS EN 1015-3BS EN 1015-4BS EN 1015-6BS EN 1015-7BS EN 1015-9BS EN 1015-10BS EN 1015-11BS EN 1015-12BS EN 1015-17 BS EN 1015-18BS EN 1015-19BS EN 1015-21BS ISO 5725-2Incorporates the following:Amendment, January 2010.
