Water quality. Guidance on the estimation of fish abundance with mobile hydroacoustic methods Ingestion-build-823961 Scope This European Standard specifies a standardized method for data sampling and procedures for data evaluation of fish populations in large rivers, lakes and reservoirs, using hydroacoustic equipment deployed on mobile platforms (boats and vessels). This standard covers fish population abundance estimates of pelagic and profundal waters > 15 m mean depth with the acoustic beam oriented vertically, and the inshore and surface waters of water

A short method applicable when either a sample has no odour and flavour or when the odour and flavour are to be compared with a specified threshold number

This document specifies a method for the determination of the nominal equibiaxial flexural strength by the ring-on-ring test of advanced monolithic technical ceramic materials at room temperature

This European Standard specifies a method for the pressure digestion of foodstuffs intended for the determination of elements

02 and can therefore be conveniently used to study the variation of dynamic properties with temperature and frequency through most of the glass-rubber relaxation region (see ISO 6721-1)

It applies to all types of organizations
