What is ISO 16000?

Definition

ISO 16000 is a multi-part ISO series of reference methods for indoor air: sampling strategy, laboratory determination of specific pollutants and emission testing of building products.

Who uses it

Indoor air laboratories, building product manufacturers, consultants and certification programs cite ISO 16000 parts when a result has to stand up to scrutiny, for example in a complaint investigation or a product emission label. Because each test samples air and analyzes it in a laboratory, results describe a short window, not a continuous record.

Parts most often cited

Titles as listed by ISO:

  • Part 1 (2004): general aspects of sampling strategy
  • Part 3 (2022): formaldehyde and other carbonyl compounds by active sampling
  • Part 6 (2021): VVOC, VOC and SVOC by active sampling on sorbent tubes, thermal desorption and gas chromatography
  • Part 11 (2024): sampling, storage and preparation of building product specimens for VOC emission testing

Using continuous VOC data to time reference sampling

Sensors and ISO 16000 methods answer different questions. Aqueduct tracks a VOC index per zone continuously, which shows when concentrations rise, for instance a nightly climb during cleaning, and which zones are affected. That tells a laboratory when and where to sample, rather than booking a test on a quiet day.

Questions

ISO 16000: common questions

ISO 16000 is the reference toolkit of laboratory methods for measuring indoor air, published by ISO in many separate parts. Each part fixes how to sample or analyze one thing, such as formaldehyde or VOCs, so results from different laboratories can be compared. Continuous sensing is covered on the VOC monitoring page.

No. A VOC index sensor reports a relative signal, while ISO 16000 methods identify and quantify compounds in a lab. Sensors suit trends and alerts between reference tests, and they help decide when a laboratory sample is worth taking.

No. ISO 16000 is a set of test methods. Rating systems and product labels reference its parts, but nobody certifies a building to ISO 16000 itself. A WELL or product emission claim may still rest on laboratory results produced with these methods.

When a result has to be defensible: an occupant complaint, a fit-out handover, a product claim or a rating system test. Continuous readings from Aqueduct's IAQ monitoring show the times and zones where concentrations peak, so the laboratory samples under representative conditions.
