Characterization of waste. Determination of brominated flame retardants (BFR) in solid waste1 Scope This European Standard specifies a method for the determination of selected polybrominated flame retardants (BFR), chemically known as polybrominated diphenylethers (BDE), in waste materials using gas chromatography mass spectrometry (GC MS) in the electron impact (EI) ionisation mode (GC EI MS). When applying GC EI MS, the method is applicable to samples containing 100 g kg to 5 000 g kg of tetra to octabromodiphenylether congeners and 100 g

BS ISO 12647-1:

Standards of EN 50083 series deal with cable networks for television signals

release for use and on-going management of hot and cold water services in buildings

This European Standard specifies requirements and describes test methods for pressure gauges and pressure switches

The biochemical and physiological variables used for this purpose are often called biomarkers

All the calculations developed in BS EN 62226-2-1 use the low-frequency approximation in which displacement currents are neglected

Method A: determination of bulk density only by measurement of dimensions and mass

The objective of this standard is to define limits and test methods for electromagnetic emissions and immunity test requirements in relation to conducted and radiated disturbances

As second issue

— collapse under external pressure in deep water
