Dear All,
BS ISO 15176 is a very "permissive document" and does not contain this type of guidance - more about what you might test for and how in different situations (I am one of the principal authors).
ISO 10381-8 on stockpiles has something but nothing of substance that you won't find in the documents mentioned below.
You might look at BS EN 14899:2005, Characterization of waste - Sampling of waste materials - Framework for the preparation and application of a sampling plan.
And available from BSI:
PD CEN/TR 15310-1,Characterization of wastes - Sampling of waste materials - Part 1: Guidance on selection and application of criteria for sampling under various conditions. This includes reference to sampling from conveyor belts, pipelines, stockpiles etc. and the statistics there of.
Parts 2, 3, 4 and 5 deal with sampling techniques, sub-sampling in the field, packaging and transport and "the process of defining the sampling plan". The last includes discussion of the "scale of sampling" in relation to the size of the population (e.g. stockpile).
Then of course there is the EA guidance on sampling materials for landfill and sampling hazardous waste.
As an aside deciding whether a material is "fit for purpose" requires more than compliance with RTVs set to be protective of human health or the water environment. Is it actually a soil (some RTVs I have seen permit 30% oil to be present); does it smell?, does it present acute hazards to workers?, will it sustain plant growth or nematode worms if this is required?, does it contain asbestos?, etc etc., what are its physical characteristics?
Regards,
Mike

Hi Gerry
Not sure whether ISO 15176:2002 would provide some definitive guidance. Scope here:

Subject: Sampling frequency of product of MPL
I'm tying to get a handle on what would be considered to be a "reasonable" testing frequency of the product/output of a treatment process operated under a Mobile plant licence (or its E&W equivelent)?
The scenario I envisage is a feedstock of "contaminated" soils which are unsuitable for use on a site as is, so require to be "treated" by a process. The output of this process would be tested to show compliance with agreed site specific remedial targets which (if met) would demonstate the satisfactory treatment and confirm the suitability of the product to be used on the site.
I appreciate this question is covered by a lot of "what ifs" etc, but i am looking for a range of opinions / views on what people consider appropriate.
Details are thin on the ground at the moment, but I envisage there could be batches of feed stock passed through the treatment process. the sort of ideas I am musing over are
x samples per m3?
minimum number of samples per batch of treated soil?
what if the batch is small (say <100m3)?
what if the batch is medium (say >100m3, <500m3)?
what if the batch is large (say >500m3?)
are these reasonable descriptions of batch size?
Thoughts welcomed openly or i can collate and summarise collate responses for the list if requested.
