EN 15732: Light weight fill and thermal insulation products for civil engineering applications (CEA) - Expanded clay lightweight aggregate products (LWA)

Standard: EN 15732: Light weight fill and thermal insulation products for civil engineering applications (CEA) - Expanded clay lightweight aggregate products (LWA)    

Certification: CE Marking

Expanded clay lightweight aggregate products (LWA) for civil engineering applications (CEA) should meet the requirements as described in the standard EN 15732, which is a harmonized standard under the Construction Products Regulation (EU) 305/2011.

Scope: This standard describes the product characteristics and includes procedures for testing, marking and labelling.

This European Standard specifies the requirements for loose-fill expanded clay lightweight aggregate (expanded clay LWA) products for Civil Engineering Applications excluding the use as thermal insulation in and under buildings which are covered by EN 14063-1.

The standard covers the use of expanded clay LWA as lightweight fill and insulation materials in embankments for roads, railways and other trafficked areas and as lightweight backfill for structures.

This standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.
