FIA and SFI certifications

 FIA8860, FIA8858 helmet and head restraint certification

Newton Laboratory has been accredited since 2004 by FIA to complete the certification tests according FIA8860 on helmets and according FIA8858 on head restraint device (please refer to FIA technical lists n. 30 and n. 32).

Since 2009 Newton has been recognized by SFI-USA (www.sfifoundation.com) to complete the certification tests of helmet for car races and by SNELL–USA (www.smf.org) to complete the certification tests according the Snell/FIA Helmet Standards For Use in Children's Motorsport.

 FIA 8862:2009 advance racing seat test

Newton laboratory has been accredited in 2009 by FIA to complete the certification tests according STANDARD FIA 8862-2009 ADVANCED RACING SEAT.

Advance racing seat test  

Our equipment to test the racing seat, mod RST 1575, has been developed by Newton together with AD Engineering (IT).

The test rig had been designed in order to apply n. 3 loads and to increase these forces simultaneously up to the target values.

Each ram is equipped with a load cell and a linear displacement transducer.

The movement of the stems is automatically driven by the software through an algorithm that involves a closed control loop between the valve of the cylinder – the displacement value – the force measured.

Moreover other three displacement transducers are available to measure the deflection of the centre line according FIA8862:2009.

It is possible to use only one cylinder as well as any couple.
The time to get to the target value can be decided before the test.
The load history (force vs time) is kept linear for the three rams.
The maximum force applicable with the pulling stems is 25 kN, the maximum force applicable with the pushing stems (which
can be inward or outward the seat) configuration is 50 kN.

The equipment is designed to test either floor only mounting (nominal 4-point) or floor and seat- back mounting (nominal 6-point) seats.

If the seat is configured for 6-point mounting, an upper seat- bracket must also be provided for the test, this part will be fastened to a rigid attachment point on the test apparatus. According SFI 39.1 the seat back will be mounted to the shoulder bar of the vehicle roll cage.

The equipment is currently configured to meet FIA8862:2009 and SFI 39.1 specification (at present time feb.

2010 only preliminary tests, NOT certification)

Software

The software has been developed by Newton with AD Engineering in order to complete both the FIA and SFI tests.

The software has been written to control the movement of the n. 3 cylinders and to acquire all the 6 displacement transducers + n. 3 load cells. In addition it can calculate the energy [J] during the deformation of the seat.

The software can be customized to change the speed of the quasi static test or the ramp for the application of the load.
The software has been validated according ISO17025 requirements.

Besides the normal automatic use the test rig can be used with manual movements controlled step by step by the technician.
