Water, acid and total Sulphur, oxidisable sulphates and total potential sulphate TRL 447

Water, acid and total Sulphur, oxidisable sulphates and total potential sulphate TRL 447

TRL 447 identifies test methods to determine Sulphate compound on soil and water extracts as an alternative method to BS EN 1744 by use of technological equipment including ICP to determine analytical values rather than the EN methods which are  reliant on manual ‘wet chemistry‘ techniques.

Determined values are derived on 2:1 water/soil extracts in accordance with TRL 447 Special Digest 1 and are a requirement of the Specification for Highway Works in determining the suitability of constructional materials.

Nicholls Colton is *UKAS accredited for the analysis of sulphates in accordance with TRL447.
