Extreme environments

Standards S1066 and 1-085 (Section 12)

Luminaires supplied to London Underground stations must follow a strict set of safety standards, and Designplan has been fulfilling these requirements for more than twenty years.

Products must be as vandal resistant as our standard products, with extra specifications for fire safety and flammability.

Several of our products are compliant with the Fire Precautions for Subsurface Railway Stations Regulations’ 1989 (UK) and 2009 (England only), commonly known as Section 12. They also meet the London Underground subsurface standard 1-085 and feature glass (rather than plastic) diffusers, low smoke cables and a compliant paint finish.

Anti-ligature and burns test

Designplan has been the supplier of choice to the custodial sector for over twenty years, and we’ve developed many luminaires specifically for this market.

Anti-ligature is a key requirement of specifiers in this sector, and through working in conjunction with prison engineers and industry experts, many of our custodial fittings are HMPPS (Her Majesty’s Prisons and Probation Service) ‘safer cells’ compliant. This means the products we make are specifically designed to prevent harm to cell occupants and staff, and to stand up to these rigours year on year.

Designplan fittings are already well-suited to this environment with tough bodies, vandal resistant diffusers and tamperproof screws, but our custodial fittings go several steps further. Their bodies are fitted flush to the mounting surface, ensuring there is no gap for anything to be inserted and that ligatures will naturally slide off surfaces rather than stay attached. Diffusers are sealed in tightly, meaning there is no gap for anything to be inserted into.

Prison cell fittings are also tested for flame resistance. Our diffusers will resist extended periods of naked flame attack, preventing any risk of holes being created which could be used to attach ligatures.
