CEN Standard Sand EN 196-1
This sand shall have been granted a CEN certificate by the national standardization organisation.
In view of the difficulties of specifying CEN Standard Sand completely and unambiguously it is necessary during certification and quality control testing to
standardise the sand against the CEN Reference Sand , described in EN 196-1.
CEN Reference sand is a natural, siliceous sand consisting preferably of rounded particles and has a silica content of at least 98 %.
The moisture content is less than 0,2% expressed as percentage by mass of the dried sample. Its particle size distribution lies within the limits defined in Tab.
CEN Standard Sand may be delivered in separate fractions or premixed in plastic bags with a content of 1350 ± 5 g.
