Understanding VOC Testing

What Is a VOC Test?

VOC (Volatile Organic Compounds) testing is the process of detecting and measuring airborne chemicals emitted from various materials and processes. These compounds can be found in building materials, cleaning agents, industrial emissions, and even everyday household products. Some VOCs are harmless, while others can be hazardous to human health and the environment.

A VOC test is essential for identifying potential risks, ensuring indoor and outdoor air quality, and maintaining compliance with UK environmental and planning regulations.

VOC Testing Services

The Encon Associates Approach

At Encon Associates, we adopt a structured, evidence-led approach to VOC testing, tailored to the specific requirements of each project. Every assessment begins with a thorough site evaluation, during which we identify the type of development or facility involved and assess potential sources of VOC emissions. This initial step ensures our testing strategy is both targeted and efficient.

We collect air samples using advanced equipment, which are then analysed by accredited laboratories to determine the presence and concentration of volatile organic compounds.

Frequently asked questions about VOC Testing

Want to know more about the benefits of a VOC Test?

A VOC test is required when a building needs to meet a minimum compliance requirement when it comes to air quality of its users.

A VOC test is conducted under controlled conditions via pumped sampling within strategic rooms of a development. A sample is taken over a set duration at a set pumping volume, and the sample is analysed for its quantity of VOC within the air. The analysis is carried out in specialised labs under UKAS-accredited and controlled conditions to ensure accuracy.

The key considerations in a VOC test include ensuring that sample rooms are assessed under the conditions they will be utilised and maintaining strict procedures to eliminate any risk of contamination during testing. All tests must be completed using calibrated equipment and uncontaminated test samples.

Encon Associates carry out two types of VOC testing. The first is Total VOC’s. This is a test of a full suite of VOC types that gives a resulting level in μg/m³. A level of equal to or less than 300μg/m³ is considered best practice. The second test that we carry out is Formaldehyde testing. A level equal to or less than 100μg/m³ is considered best practice.

The majority of VOCs are harmful to health, especially in high levels. Some VOCs are known to cause cancer and other health defects, therefore, any risk associated with VOCs must be minimised.
