HIC TEST 2018 APARATUS

 

 

Being a manufacturer of HIC APPARATUS (Head Injury Criterion apparatus), according to the new standard EN 1177:2018, may we present the new guidelines and recommend the purchase of the equipment. The price will be set individually.
On 1 Jul 2018, the standard PN-EN 1177:2009 ceased to apply. The new standard PN-EN 1177:2018 has introduced numerous changes and restrictions. Therefore, the devices used so far on the European market require adaptation to the requirements of the new standard PN-EN 1177:2018.

 

APPARATUS FOR DETERMINATION OF IMPACT ATTENUATION
According to the standard EN 1177:2018
TECHNICAL GUIDELINES
and
Implementation requirements
 


1. THE PURPOSE

The APPARATUS FOR DETERMINATION OF IMPACT ATTENUATION is intended to provide information on the surface ability to reduce the impact force to a person’s head. Its main function is to test and determine the value of head injury caused by the fall, according to the standard EN 1177:2018.

 

2. COMPONENTS OF THE APPARATUSA

  1. a hemispherical headform in accordance with PN-EN 1177:2018 requirements
  2. an accelerometer for three axes, mounted at the centre of gravity of the headform
  3. an accelerometer signal conditioner
  4. a device recording the acceleration signal
  5. a program for supervising the system, calculating the HIC value and presenting the measurement results
  6. a program for presenting the measured gmax results
  7. an electromagnetic headform release bolt

 

3. TECHNICAL REQUIREMENTS according to EN 1177:2018

3.1. The accelerometer

  1. range of measuring the signal frequencies              - 20 - 1000 Hz    parameter in compliance with the new standard EN 1177:2018
  2. maximum measurement error                                   - < 5%                  parameter in compliance with the new standard EN 1177:2018
  3. number of measurement axes                                   - 3                         parameter in compliance with the new standard EN 1177:2018

3.2. Accelerometer signal conditioning system

  1. sensor signal sampling rate                    - >= 20 kHz
  2. anti-aliasing filter                                      - When the -3 dB upper frequency response of the accelerometer with the signal conditioning system is at a frequency greater than one-quarter of the sampling frequency, an anti-aliasing filter with an attenuation of at least 30 dB at half the sampling rate is to be employed.
  3. number of simultaneous conversions   - 3

 

3.3. Acceleration recording device

  1. measurement recording period                            - max. 2 s     parameter in compliance with the new standard EN 1177:2018
  2. number of data channels recorded                      - 3                  parameter in compliance with the new standard EN 1177:2018

3.4. System controlling program — features & functional requirements

  1. Windows-compatible (Win 7, Win 10)
  2. entering the measurement parameter (drop height)
  3. initiating the measurement cycle (controlling the headform release bolt)
  4. recording acceleration time history (using *.csv file format)
  5. presenting acceleration time history graph on screen
  6. calculating the HIC value for the recorded data
  7. printing the recorded data

 

3.5. Electromagnetic headform release bolt

  1. release power                                         - < 12V/2A max    parameter in compliance with the new standard EN 1177:2018

  2. bolt displacement force                        - ~ 3 kG                 parameter in compliance with the new standard EN 1177:2018

  3. bolt displacement velocity                    - ~ 100 mm/s        parameter in compliance with the new standard EN 1177:2018

 

4. WARRANTY

  1. The warranty period is 12 months from the date of purchase.
