SAND EN ISO 12956 geotextiles opening test
Method: opening test EN ISO 12956
USAGE
Sand is used in the test method for determining the characteristic filtration opening of a geotextile
TECHNICAL CHARACTERISTICS
The sand is of the natural siliceous type with a water content of less than 0.1%. The constituent grains of these sands are uncrushed and round-shaped. It has a silica content greater than 98%
The granulometric curve lies within the time zone defined by standard EN ISO 12956
| Mesh (mm) | Specification | |
|---|---|---|
