Sample acceptance conditions
Check these conditions before you take your samples. Samples that do not meet them may be rejected. If that happens, we will let you know before the analysis starts.
01Paint and insulation
- Deliver in the SEEF sample container (SE01), available to order via WeLIMS, or in a resealable bag no larger than A5.
- Not accepted: socks, adhesive samples and aluminium foil. Not recommended: organza bags, coffee filters, resealable bags larger than A5 and cyclones.
- Pack all containers or bags together in one sealed outer bag (double-bagged).
- At least 1 gram. A full sugar sachet (approximately 2 grams) is more than enough. Using a bag larger than A5 or a cyclone? Then send approximately 2 grams.
- Deliver dry, and dry a wet surface before sampling. We do accept wet samples, but this is noted on the certificate and we cannot commit to the 5 working day turnaround.
- Sample from a clean surface, free from soil, sand, concrete residue, blasting grit, glass, wood or insects.
- More about the analysis: chromium 6 laboratory analysis and our knowledge base.
02Air samples
- Only air filters from SEEF Laboratorium, identifiable by their unique code.
- Deliver dry in the cassette, with the filter intact.
- Samples keep for two weeks after sampling, so send them as soon as possible. The sampling date is a mandatory field in WeLIMS.
- Include a field blank with every order: filter in the pump, pump not switched on (0 m³), coded and registered as a regular sample.
- Air samples are part of a chromium 6 exposure assessment.
03Wipe samples
- Only SEEF wipes (WS01), available as a chromium 6 wipe sampling kit in our webshop. We cannot analyse wipes from other suppliers.
- Deliver dry.
04Coding and identification
- Give each sample a unique code, preferably sequential: M01, M02, M03.
- Give each project its own reference number, and put it on the outer bag as well.
- The codes on the samples must match your registration in WeLIMS.
05Blasting grit, steel slag, concrete and other materials
- The same requirements apply as for paint and insulation: packaging, dryness, purity, quantity and coding.
- These materials fall outside the validated scope of the analytical method.
- Dealing with scrap metal? Read about the EURAL code for scrap containing chromium 6.
06Samples suspected of containing asbestos
- SEEF does not analyse samples that contain asbestos.
- If asbestos is suspected, we will only start once we have been in touch with you, for example about an asbestos survey report.
