Dear friends and colleagues,
We, me and my colleagues, have an intent to extend the range of our laboratory including some test of soils. I have to find some standards describing the mentioned tests.
Unfortunately, I couldn't find all of them...So, I need your help again. It is not urgent. The missing standards which I need are:
1. BS ISO 10390:2005 Soil quality. Determination of pH
2. BS 7755-3.10:1995, ISO 10693:1995 Soil quality. Chemical methods. Determination of carbonate content. Volumetric method
3. BS 7755-3.8:1995, ISO 10694:1995 Soil quality. Chemical methods. Determination of organic and total carbon after dry combustion (elementary analysis)
4. BS 7755-3.11:1995, ISO 11048:1995 Soil quality. Chemical methods. Determination of water-soluble and acid-soluble sulfate
5. BS 7755-3.7:1995, ISO 11261:1995 Soil quality. Chemical methods. Determination of total nitrogen. Modified Kjeldahl method
6. BS 7755-3.4:1995, ISO 11265:1994 Soil quality. Chemical methods. Determination of the specific electrical conductivity
and optionally (if it is possible):
7. BS ISO 11709:2011 Soil quality. Determination of selected coal-tar-derived phenolic compounds using high performance liquid chromatography (HPLC)
Thanks in advance.
