Rubber smell is not an emissions result
A rubber smell is an observation, not an indoor-emissions result. For granules destined for indoor tiles or flooring, separate odour acceptability from chemical-emissions requirements and ask what product was tested. A raw-granule report does not, by itself, establish the emissions of the finished floor or approve it for indoor use.
Explore the questionsThree different questions
- Odour
Is the smell acceptable under a defined assessment? This is not a chemical concentration result.
- Emissions
Which substances were measured, under which test conditions, and against which requirements?
- Finished floor
Does the evidence cover the product and installation your customer will actually use?
Low smell is not proof
Some emissions may be present without a noticeable odour. A sniff test cannot establish indoor suitability.
Check the test object
Loose granules, a bound tile and an installed flooring system are different things to assess.
Define the destination use
Ask the specifier or laboratory which emissions and odour requirements apply to the intended indoor product.

Can smell tell you whether emissions are acceptable?
Odour matters to users, but it is not a substitute for chemical measurement.
Health Canada explains that volatile organic compounds, or VOCs, can be present even when they cannot be smelled. Their health relevance depends on the substances, concentration and duration of exposure.
For a buyer, the practical distinction is straightforward: an odour complaint deserves attention, but its strength is not a measured emissions result. Equally, a weak smell is not proof of negligible emissions. Do not turn either observation into a blanket safety claim.
The German Environment Agency’s building-product guidance treats odour and chemical emissions as related but distinct issues. This is general indoor-material guidance, not a test of Bedrock granules.
What does a laboratory measure?
Ask separately about a chemical-emissions method and an odour-assessment method.
The public scope of ISO 16000-9:2024 describes chamber testing of VOC emissions from building-product samples under controlled conditions. ISO 16000-28:2020 addresses odour emitted from building products and materials using test chambers and evaluation procedures.
These are different assessment questions. The presence of a method name alone does not mean a product passes your project’s requirements. Ask the laboratory which method, specimen preparation and assessment criteria fit the intended use. This guide cites public standard scopes; it does not reproduce the test procedures or establish that either method is compulsory in every market.
Did the report test granules or the flooring product?
Keep the material evidence separate from a claim about the finished floor.
For a flooring manufacturer, start with the identity of the tested specimen: loose granules, a bound tile, a roll, or a defined assembly. Then check whether the binder, surface finish, backing and any installation adhesive relevant to the claim were represented.
Health Canada’s guidance identifies glues and other building materials among indoor VOC sources. As a practical consequence, a result for one raw component should not be treated as a result for every finished formulation or installation that uses it. Have the responsible laboratory or specifier determine the necessary assessment scope.
Keep public studies in their proper place too. Research about outdoor sports infill cannot simply approve an indoor floor. Our guide to crumb-rubber research explains why the scope of evidence matters.
What should you ask before ordering granules?
Give the supplier the indoor application and evidence requirements, not just the words 'low odour'.
For rubber granules used in flooring manufacture, include these points with the required grade and quantity:
- The indoor product you intend to make and its destination market.
- The emissions assessment or customer specification you must meet.
- Whether a defined odour assessment is also required.
- Which evidence you need for the raw material and which testing belongs to your finished product.
Ask us what supporting information is available for the proposed granules. Do not assume a low-emission certificate, odour rating or indoor-use approval is available until it has been confirmed and its scope checked. Avoid promising customers that a smell will disappear after a fixed number of days without evidence for the actual product and conditions.
Making an indoor rubber product?
Tell us the product, grade, quantity and destination, plus the emissions or odour evidence your specification requires. We can confirm what material information is available for your evaluation.
Discuss granules for your productCommon questions
Does no rubber smell mean no VOC emissions?
No. Some VOCs may be present without a noticeable smell. Use the relevant measured evidence rather than odour alone to assess emissions requirements.
Does a strong rubber smell prove that a floor is unsafe?
Smell alone cannot establish that conclusion. Investigate the concern and use appropriate evidence about the substances, exposure and product. Do not dismiss an odour complaint or diagnose the risk from its strength alone.
Can a granule test report certify my finished tiles?
Not by itself. Check whether the report and assessment cover your actual finished product, its other components and the conditions relevant to the claim. Your laboratory or specifier should define the necessary evidence.
