Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of humic substances from solid samples1 Scope This part of ISO 12782 specifies a procedure to determine the concentration of humic substances in soil or other materials. Other materials also include waste. The content of humic substances can be used as input in geochemical models.

BS EN 61909 defines the mechanical and electrical characteristics necessary to ensure the interchangeability of both premastered optical discs and recordable magneto-optical disc for the compressed digital audio recording system

BS EN 1993-1-2 deals with the design of steel structures for the accidental situation of fire exposure and is for use in conjunction with BS EN 1993-1-1 and BS EN 1991-1-2

and design support to improve the maintainability of equipment

Vibration on handheld or hand-guided machinery is measured to determine the vibration dose by combining the measured vibration accelerations with the time history over which the tool is used during a typical working day and to compare the vibrations from different tools or machinery or different models of the same tool

The principal change from BS 6263-2:1982 is that BS 6263-2:1991 now covers recommendations for textured flooring
