Ergonomic and Dimensional Testing

Ergonomics Crop

There are a number of British (BS), European (EN) and international (ISO) Standards relating to ergonomics of products in use, mainly for the office, contract and educational markets.

These Standards are mainly dimensional Standards for office and educational environments. A vast majority of office and contract furniture users will not purchase office chairs and tables unless they have been tested and certified by an independent third party.

Compliance of office, school and domestic furniture, equipment and work environments with Health & Safety and DSE (Display Screen Equipment) regulations.

FIRA International is able to rigorously test all office, school and domestic furniture, equipment and work environments to existing Standards and for compliance of office furniture with Health & Safety and DSE (Display Screen Equipment) regulations.

We can test to a wide range of Standards depending on the type and intended use of your furniture products.

Dimensional Standards

  • BS EN 1335-1: 2000. Office chair dimensions. NOTE: this standard is prerequisite to EN ISO 9241-5.
  • BS EN 527-1: 2011; Desk dimensions
  • 1729-1: 2006. School furniture. NOTE: this standard is prerequisite for BS EN 1729-2: 2006. Therefore you cannot test to Part 2 before you test to Part 1.
  • EN 16139: 2013. Visitor chairs dimensions.
  • BS EN 1023-1: 1997. Dimensions of office screens.

Ergonomic Standards

  • BS EN ISO 9241-5:1999. Ergonomics of chairs, desks workstations. This tests chairs, desks and workstations, monitor arms, laptop and tablet holders and many other items.
  • BIFMA G1

Additional dimensional and ergonomic Standards

  • BE EN ISO 11064-4: 2013. Layout and dimensions of control room work stations.
  • NPR 1813 for office chairs

We also evaluate products for the FIRA International Ergonomics Excellence Award. This award recognises companies who design and manufacture ergonomically outstanding products, especially those that meet and generally exceed the requirements of British and European Standards.

Where no Standards exist, we can develop appropriate new ones. Currently the department are working on the development of a Standard for bariatric furniture.
