Natural stone test methods. Determination of resistance to salt crystallisation Ingestion-build-48024 The actuation of an alarm

The actuation of an alarm signal when either a predetermined volumic activity or a predetermined total released activity of aerosols is exceeded

This European Standard specifies procedures for determining the weldability lobe for producing quality welds

The PPE is not intended to provide protection during fire entrapment

The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artefacts on the sorbent

Natural stone test methods. Determination of resistance to salt crystallisation Ingestion-build-48024 The actuation of an alarm1 Scope This document specifies a test method to assess the relative resistance of natural stones with an open porosity of greater than 5 %, measured in accordance with EN 1936, to damage caused by the crystallization of salts. The test is not necessary for low porosity stones.
