6 -TerraIndex offers an asbestos calculation based on analysis data, according to BRL2018 / NEN 5707.
6 +This calculation flow, in very basic steps, describes the process of doing asbestos research, using the SIBK BRL 2018 and the NEN5707 / NEN 5897 as a guideline. This flow is there to give a basic idea of the processes in asbestos soil research.

8 +First, historical research (NEN 5725) has to be done to be able to make an initial strategy for the research plan. Once the fieldworker arrives at the location, a visual inspection of the ground level has to be done, if possible. If the suspicion of asbestos is in a lower layer of soil, e.g. 0,5-1m, there's no need for an inspection) The process of an asbestos inspection is explained in 1.1

10 +After the field inspection, an hole needs to be drilled. There are two types of inspection holes in asbestos research, an asbestos inspection hole (usually 0,3m in diameter, x 0,5m in depth) for explorative research and an asbestos trench for further research (usually 0,3m wide, at least 200cm long but this can differ depending on the research location / research plan!). The process of sampling asbestos is explained in more detail in section 1.2. 
11 +
12 +After sampling the sample needs to be properly packaged and marked to send towards a lab for analysis.
