High temperature combustion of the sample in oxygen using an elemental analyser. The resultant nitrogen gas is measured by thermal conductivity detection.
A number of different publications and standards cite sulphate methods. BR279 (1995) has largely been superseded by analytical procedures as detailed in TRL 447 and BRE Special Digest:1 2005 3rd Edition. In addition further reference may be made to BS EN 144-1:2009 + A1:2012 for the testing of aggregates and BS 1377:2018 for soils for civil engineering purposes.
Testing to meet the requirements of UKWIR Report Ref. No. 10/WM/03/21 Guidance for the selection of water supply pipes to be used in brownfield sites.
Testing & reporting is undertaken in accordance with BS 3882:2015 Specification for topsoil and BS 8601:2013 Specification for subsoil and requirements for use
