Certification is granted to the sampler and the scope is limited to environmental sampling, excluding aspects such as sampling planning.
Nordtest Certification of samplers can be granted for the following matrices:
Solid wastes as follows:
- granular wastes or by-products (i.e.: slag, fly ash).
Soils (defined as topsoils and geological sediments) from:
- contaminated sites
- soil piles.
Groundwaters (defined as subsurface waters) from:
- investigation wells
- drinking water supply wells.
Bottom sediments (defined as sedimentary materials) from:
- marine (i.e.: offshore, near shore and estuarine) sediments
- lake and similar standing water bodies’ sediments.
Waste waters as follows:
- industrial waste water
- raw domestic waste water and
- treated domestic waste water.
Sampling of accidental spillages is not included in the scope for waste water sampling.
Solid sludge from waste water works and industrial processes (defined as sludge of min. 10% dry matter) for agricultural use and sampled from:
- well-defined stocks and beds or
- opened containers.
Certified sampling of solid sludge can only take place from batches (stockpiles or containers) of well-defined geometry. Additionally, sampling of solid sludge according to the scope of solid waste can be certified.
Certification for sampling of waste waters and solid sludges may be granted jointly.
Surface fresh waters from:
- flowing-water (rivers and streams)
- Still-water (lakes and ponds)
The scheme handbook covers sampling for physical/ chemical, biological and microbiological characterisation. The certification scheme is open for samplers that meet the requirements of Section 2.2 with respect to sampling performance.
The sampler can be certified to do sampling according to the principles stipulated in Section 2.3.1, with methods and equipment stipulated in Sections 2.2.1, 2.2.2, and appendix, Section 2.2.1, and following the requirements for quality control and documentation given in Sections 2.3.2 and 2.3.3, and appendix, Section 2.3.1.
