CEN/TC 178

Paving units and kerbs

Standardization of the performance requirements and their associated methods of test of paving units, kerbs and accessories manufactured from clay,concrete, natural stone or other materials used for the surfacing of footways, roads and other paved areas (dock, industrial, parking) considering their application.

CEN/TC 246

Natural stones

Definitions, requirements and test methods for natural stones relating to rough blocks, slabs, semi-finished and finished products intended for use in building and for monuments with the exception of items in the field of work covered by other Technical Committees. The WG 4 (JWG 229/246) covers the agglomerated stones for floor coverings, wall coverings and ancillary uses, for interior and exterior use, with resin or cement binders or a combination of the two and does not cover pressed tiles such as terrazzo tiles which are the territory of CEN/TC 229, or natural stone which is the territory of CEN/TC 246. Note: Reference should be made as far as possible to existing test methods. Submission of WG 4 documents for the formal vote must be decided by resolutions of the two CEN/TCs.

ISO/TC 24

Particle characterization including sieving

Standardization pertaining to equipment and methods used in size classification or size classification of particulate material where particles may be considered to include grains, flakes, fibres, droplets, bubbles or pores from the nanometre to the millimetre scale. Covering the following: Particle and particle ensemble characterization, mainly by determination of physical properties of the particles including, for example, size distribution, particle shape and morphology, weight, density, surface area or porosity, and mobility Particle systems characterization comprises particle-fluid and particle-particle interactions in suspensions, emulsions, aerosols or powders by determining their properties including concentration, electric charge, zeta potential, state of agglomeration, stability and rheology. Test sieves, sieving methods and industrial screens. Each of the above areas will comprise standardization in the field of laboratory or process environment including terminology, reference materials, guidance for sampling, sample preparation, interpretation of results and uncertainty determination.
