Water quality. Determination of nitrite nitrogen and nitrate nitrogen and the sum of both by flow analysis (CFA and FIA) and spectrometric detection LONG_TITLE The prediction of the ageing

The prediction of the ageing of plastic materials is an important subject that concerns both users and manufacturers of materials

BS EN 2240-016 provides you with dimensions

BS EN 14934:2007 describes product characteristics and includes procedures for testing

This Part 2-29 of EN 50290 gives specific requirements for Crosslinked Polyethylene (XLPE) compounds to be used for the insulation of instrumentation

in order to better fit in the modular structure given in EN ISO 52000-1

Water quality. Determination of nitrite nitrogen and nitrate nitrogen and the sum of both by flow analysis (CFA and FIA) and spectrometric detection LONG_TITLE The prediction of the ageing1 Scope This International Standard specifies a method for the determination of nitrite(N) (see note 2), nitrate(N) or the sum of both [nitrite nitrate(N)], in various types of waters (such as ground, drinking, surface, and waste waters) in mass concentrations ranging from 0,01 mg l to 1 mg l for nitrite(N) and from 0,2 mg l to 20 mg l for nitrite nitrate(N), both in the undiluted sample. The range of application can be changed by varying the
