REMA | REMA Sponsors Passive Safety Event
The Retroreflective Equipment Manufacturers Association (REMA) is sponsoring a Passive Safety workshop in June which will explain to managers, designers/safety engineers and specifiers the changes required by a new standard EN12767:2019 (Passive Safety) and a new National Annex being published later this year.
REMA has long been associated with Passive Safety as many of its members produce unharmful, lightweight and deformable or self-righting products which are compatible with Passively Safe design. The REMA Secretary, Andrew Pledge, has for many years been involved with the promotion of using Passive Safety products as a way to significantly reduce both the number and severity of casualties resulting from collisions with roadside furniture.
The workshop will take place on Tuesday 25th June at the National Conference Centre – Birmingham (Just off the M42 J6). Speakers at the event will explain in detail that not only post performance, but now the type of foundations/backfill, mode of failure, risk of windscreen penetration and likely direction of impact are also to be specified. There will be the opportunity to circulate to attendees a list of existing passive products with their new classifications, which is currently being prepared with the help of the individual manufacturers.
There will also be an opportunity for participants to learn about the new classes in detail and how to continue to specify existing and new products for particular situations once the new standard (containing a new UK National Annex) is published. There will be information provided on other changes to this standard and more generally, the use of other related European Standards following Brexit.
In more detail, the new standard will change the way in which existing and new passive products are classified, affecting how they will need to be specified. Whilst the energy absorption classes for existing products remain unchanged (HE, LE or NE) the speed class and Occupant safety level class will change.
With regard to the speed class, depending on the observed collapse mode, the new standard now allows products to be declared in more than one speed class, without being tested at other speeds. Whilst the speed classes for existing products remain unchanged, it may be that additional classes can be declared for them, dependant on the observed collapse mode when they were originally tested.
Changes to the classification of occupancy safety level are that HE or LE 1, 2 or 3 become HE or LE E, D or C and NE 1, 2, 3 or 4 become NE D, C, B or A. However, it is now also possible for there to be a specification of HE B, LE B, or NE B and an NE E.
There are also additional classes defined in the new standard. These are: Backfill Type, Collapse Mode, Direction of Impact and Risk of Roof Indentation. There are now three types of Backfill class identified: S (Standard aggregates), X (Special Foundation) and R (Rigid Foundation). There are two types of collapse modes identified, SE (Separation) and NS (Non- separation). These relate to how the product behaves upon impact. There are three direction classes identified, MD (Multi-directional), BD (Bi-directional) and SD (Single directional). These relate to whether the product performs in the same way when struck from different approach angles. There are two classes of roof indentation now identified, 0 (Vehicle Roof deformation less than 102mm) and 1 (Vehicle Roof deformation equal to or greater than 102mm).
The workshop is endorsed by Highways England:
“Passively safe structures play a key role in making the road environment more forgiving. However, it is important that designers are aware of and understand the requirements of the standard to allow them to design and specify appropriate products to ensure that the positive safety benefits are achieved. Highways England welcomes initiatives to educate and inform designers and specifiers to improve safety and I am happy to support this workshop”.

The intended outcome of this event is to enable a smooth transition to the use of the new standard without significant delays in the use of passive products. As such, you are encouraged to actively participate to help us to achieve this aim. If at this stage you have any other questions regarding the event please do not hesitate to get in touch with Andrew Pledge at email@example.com
Delegate places are £125.00 + VAT (A 20% discount is available for CIHT and IHE members).
