Gas capacity testing services

Exposure to certain gases is a serious concern for people’s wellbeing and safety therefore there are a wide range of devices available to offer protection against these hazards. The defence against these vapours is widely known as ‘Gas capacity’ and is a necessity in many industries where workers are exposed to these risks such as the petrochemical, pharmaceutical and water treatment industries where things such as sulphureted and organic vapours are a daily risk.

With the need to comply with health and safety regulations to keep employees safe, it’s obligatory that employers provide their employees with appropriate PPE and ensure its correct use. Manufacturers producing this type of equipment must ensure their products conform to the relevant National, European or International Standard or to a Technical Specification and are CE marked currently to the PPE Directive 89/686/EEC though this will be replaced on 21 April 2018 by the PPE Regulation (EU) 2016/425.

In support of these manufacturers in placing respiratory products into the European market BSI has opened and new gas capacity laboratory which offers a range of testing services. Some of the gases we can test and where they are found is below;

  • Cyclohexane, used as a solvent, can be found in household products such as adhesives or paints. Most of the production is employed in the nylon industry.
  • Chlorine is applied directly to disinfect water. As bleach, it can be located in any household. It can also be exploited as a raw material for chloroform and PVC.  Additionally, chlorine is used in the paper industry.
  • Hydrogen sulphide is a by-product of anaerobic processes (for instance, in waste treatment plants) and natural gas.  It is an important intermediate of sulphuric acid and agricultural products..
  • Hydrogen cyanide is part of the smoke of tobacco and car exhaust.  At an industrial level, it’s put in service for fumigation or metallurgy. Furthermore, formonitrile is  a precursor for acrylonitrile.   
  • Sulphur dioxide. is a by-product of the cement industry. It’s widely accepted as a food preservative (for dried fruits), as an antioxidant in the oenological industry, and as an industrial refrigerant, among other areas. 
  • Ammonia. It is habitual in fertilisers. and in industries such as textile and explosive. Usually present as a household cleaner, it can be used as an antimicrobial agent in the food industry.    

As part of the many services that BSI can offer, we can guide you through relevant Standards and the processes to comply with the PPE Directive and Regulation covering this area. Companies around the world rely on the integrity of our test reports and they are widely recognised and respected as a third party assessment to demonstrate compliance. BSI’s experience and expertise in product testing means we can go beyond and develop tests at our Centre of Excellence in the UK that can help to identify potential problems in the design process, optimising time and money. 

For manufacturers and distributors who wish to have products assessed against their own specifications, we can formulate bespoke tests to meet their individual needs. We offer a one stop shop for certification and testing of respiratory products and are the only independent laboratory certified against 17025 by the UKAS to carry out these kind of tests in the UK.

We provide testing facilities for a whole set of products, including, but not limited to:

  • Gas Filters & Combined Filters (EN 14387:2004+A1:2008)
  • Powered Hoods and Helmets (EN 12941:1998+A2:2008)
  • Powered air for full/half Masks (EN 12942:1998+A2:2008 )
  • Valved Combined Filtering Half Mask (EN 405:2001+a1:2009)
  • Methods of test described in EN 13274

Where British or European Standards do not exist or are under development, BSI can offer special test services. Likewise, we carry out testing and product assessment in other areas subjected to specific regulations.
