Safety Testing and Rating

introduction

Our composite lighting columns have been fully tested to comply with the BS:EN 12767 passive safety standard. This standard comes in three parts: SPEED, ENERGY ABSORPTION and OCCUPANT SAFETY.

The safety rating of Kingsmill columns is 70 NE 2 in accordance with BS:EN 12767 passive safety standards. Tested at speeds of 35km/h and 70km/h, Kingsmill columns are non-energy absorbing, with an occupant safety level of 2. We are also working on certification following testing at speeds of 50km/h and 100km/h. For more information, contact us for an update.

SPEED

All support structures are required to be crash tested at speeds of 35km/h, as well as one of 50, 70 or 100km/h.

A performance class of 70 is recommended for use on roads in built-up areas, where the speed limit is 40mph or below.

ENERGY ABSORPTION

The extent to which the crash vehicle is slowed by impact with a passive structure:

High Energy absorbing (HE)
– will considerably slow down, and generally stop the impact vehicle over a short distance. Risk of secondary collisions is reduced. Vehicle occupants impact severity is usually high.
Low Energy absorbing (LE)
– designed to bend in front of the impact vehicle before detaching. Reduces the speed of the impact vehicle less than an HE structure, carrying less risk to vehicle occupants.
Non-Energy absorbing (NE)
– structures are intended to shear from their foundation upon impact, lifting over the crash vehicle and allowing it to continue with minimal speed reduction. Vastly reduces the severity of the impact for vehicle occupants, and therefore primary injury risk and vehicle damage. The structure will generally fall within the vicinity of the foundation, making NE structures the recommended class for all-purpose roads and motorways in non-built up areas.
Kingsmill columns are all Non-Energy absorbing (NE) structures

OCCUPANT SAFETY

Occupant safety levels are determined by two risk requirements, from 1 to 4 in increasing safety levels:
  • Acceleration Severity Index (ASI) – expresses the accident severity for occupants of the impact vehicle.
  • Theoretical Head Impact Value (THIV) – a calculation of the hypothetical velocity (in km/h) at which a vehicle occupant would hit the occupant compartment of the vehicle (eg hitting the dashboard or steering wheel).

These two values combine to give an overall safety level of 1 to 4. Higher numbers show greater occupant safety.

Occupant safety levels from 1 to 3 are recommended for lighting structures in rural and urban areas.

SAFER ROADWAYS

Safety First
Kingsmill composite Lighting Columns are feature-packed to make roads and walkways safer places for both motorists and pedestrians alike.
For Drivers
Combine lighting and signage with intelligent systems such as speed measurement and CCTV cameras to provide dynamic monitoring and control of road users.
For Pedestrians
Pedestrian areas – including pavements, retail centres, theme parks and domestic driveways – can all benefit from the features the Kingsmill Lighting Column offers.

Not just for street lighting . . .

The Composite Pole can be combined with an LED lighting system and signage, to warn drivers of a pedestrian crossing. It is also possible to incorporate curtain motion sensors within the crossing and audible warning for pedestrians – such options being customer specific.

The composite pedestrian crossing pole could also offer intelligence (subject to feasibility and customer specification):

  • GSM module, informing emergency and other services about the occurrence of a vehicle collision with the column
  • Vehicle speed measurement
  • Wireless lighting control
  • Mounting of traffic monitoring cameras

PASSIVE SAFETY

The non-conductive Kingsmill Lighting Column reduces the speed of a vehicle and will break away and move over the top of the vehicle – combining low injury risk and excellent passenger safety.

LUMINOUS COATING (option)

The addition of coated glass microbeads on the surfaces of lighting columns outside schools, hospitals, park entrances and retirement homes or leading up to pedestrian crossings, will reflect the lights of oncoming vehicles, thus warning drivers of their approach to areas where children or the elderly may be crossing.

LUMINOPHORE COATING (option)

The column can be manufactured incorporating luminophore.

During the day, the luminophore contained in the column stores light energy from the sun. Then, at night, it releases that energy as light, over its surface. This produces a “delicate light mist” – another attractive landscaping feature.

From a safety aspect, luminophore is also stimulated by the lights from passing vehicles, thus in the case of power outages, the lighting columns and street edges are still visible to drivers.

If luminophore is also lit from a UV light source within the column, the material is stimulated to emit light and thus add to visibility of carriageway edges.
