Soil quality. Laboratory methods for determination of microbial soil respiration1 Scope This International Standard describes methods for the determination of soil microbial respiration of aerobic, unsaturated soils. The methods are suitable for the determination of O2 uptake or CO2 release, either after addition of a substrate (substrate induced respiration), or without substrate addition (basal respiration). This International Standard is applicable to the measurement of soil respiration in order to: determine the microbial

It cancels and replaces ISO 1518:1992

BS 1932-2 specifies the technicalities for two methods used to test the strength of the yarns and threads:
