A useful sample label answers two questions: what material is in the bag and where was it taken? You do not need to include an order number or printed order confirmation in the shipment.
Describe the material plainly
Use a name you will recognise later. “Tile, mortar and adhesive”, “vinyl flooring with adhesive” or “wall filler” is more useful than “sample 1”. If you do not know the technical name, a short description is enough.
Be precise about location
“Bathroom” can be too broad if both wall and floor are tested. Better examples include:
- Bathroom, shower wall, tile and underlying layers
- Kitchen, wall behind sink, filler
- Bedroom, floor, brown vinyl flooring with adhesive
Use the same name in the order and on the bag
When the online order and sample bag use matching material and location names, the report is easy to assign. Multiple bags can also be numbered, but a number does not replace the material and location description.
Keep loose paper out of the sample bag
Write on the outside of the bag or attach the label so it cannot separate during transport. Close the bag tightly. The goal is for the sample and its name to stay together until laboratory reception.
