Emission tests in car interiors

Quality and safety are two requirements that are always in demand in materials intended for the manufacture of automotive components.
One of the main objectives of the automotive industry (car manufacturers and suppliers) is to continuously improve the properties of materials used in part manufacturing for car interiors. These improvements involve continuous control in the development of the different raw materials used as well as the components and complete systems installed in the vehicle.

Emission tests on car interior components are highly demanded by companies in the automotive sector since they must comply with strict legislation and need to assess the emissions present in the air inside the car.

AIMPLAS’ laboratories were the first Spanish laboratories to obtain ENAC’s international accreditations for odour emission tests in car interiors.

In our laboratories, we conduct tests on volatile substances that may be emitted by different materials such as plastics, textiles and leathers inside the vehicle. These tests are carried out according to the specific standards of the main manufacturers, such as VW/Audi, BMW, GM, PSA Peugeot Citroën, Ford, Toyota, Saab, Porsche and Daimler-Chrysler.

Testing services available

Emission of Volatile Organic
Compounds (VOCs)

The uncontrolled emission of large quantities of different volatile organic compounds by some plastic components can make the inside of a vehicle an exposure area for users and lead to health and wellbeing issues.

Normatives: VCS 1027,2749 (Volvo), PV 3942, VDA 277, D105495, etc.

Formaldehyde emissions

Formaldehyde is a colourless gas with a strong smell composed of carbon, hydrogen and oxygen. It belongs to a large family of chemical compounds called Volatile Organic Compounds. Concerns over the presence of formaldehyde stem from the fact that high levels of this substance can cause health problems.

Normatives: VCS 1027,2739 (Volvo), PV 3925, VDA 275, GME 60271, D455535 (PSA), etc.


The level of odour inside cars is a mandatory parameter to be controlled since high levels can make the user uncomfortable. Today, it is an important challenge and concern for car manufacturers.

Normatives: VCS 1027,2729, PV 3900, VDA 270, BO13101 (Ford), etc.


There are plastic components inside vehicles that, under certain conditions, may condense and fog up the car windows. This can be dangerous when driving.

Normatives: VCS 1027,2719 (Volvo), SAE J1756, GMW 3235, BO 11603 (Ford), PV 392o, etc.
