Construction products. Assessment of release of dangerous substances - Horizontal up-flow percolation test1 Scope (1) This Technical Specification specifies an Up flow Percolation Test (PT) which is applicable to determine the leaching behaviour of inorganic and non volatile organic substances from granular construction products. The test is not suitable for substances that are volatile under ambient conditions. The construction products are subjected to percolation with water as a function of liquid to solid ratio under specified percolation conditions.

It also includes the specification of a meta-metamodel and associated rules that define a framework for the semantic metamodel and the transfer format

BS EN 12806 on Automotive LPG components is useful for:

BS EN 12312-2 also considers some requirements recognized as essential by authorities

since these can allow alternative codes and standards for GRPpiping associated with marine and/or ballast systems

and defines extension rules that can be applied without further testing

for small-bore connectors intended for use with neuraxial application medical devices or accessories

The basic LCA principles and framework are based on the EN ISO 14040 series of standards (i
