German term or phrase: HIC
"wie nach HIC geprüft" - some sort of standardisation? The thing being tested is a floor surface to be used in a children's playground and it has to be a certain thickness.

Explanation:
I found various sites for HIC, but this one seems to match best=http://www.tu-berlin.de/fb10/ISS/FG7/studis/h&s/DIPLKAP2.HTM
Otherwise HIC is some sort of hydrogen
test,see:http://www.oldenbourg.de/vulkan-verlag/rou-rrr9910.htm
BUT:Surface Performance Criteria

Given the frequency and potential severity of playground injuries, government agencies and consumers are placing increasing importance on playground safety issues. The US consumer Product Safety Commission has issues guidelines for playground safety, including the recommendation that impact-attenuating surfacing be employed beneath and around playground equipment.

Although cushioned surfacing can reduce the risk of most surface impact injuries, head injuries are of greatest concern because of their life-threatening potential. Consequently, tests and standards related to cushioned surfaces, including playground surfaces, have their basis in head injury mechanics.

There are no precise ways of determining how injuries will occur, but consensus has developed around two methods of determining the potential for head impact injury:

It is generally accepted that a head impact is not life threatening if the peak deceleration (g-max) of the head during impact does not exceed 200 g.
The time over which the head decelerates is also believed to be an important factor in head injuries. This factor is assessed in combination with the peak deceleration using the maximum value in a specified integral of the acceleration-time curve, known as the Head Injury Criterion or HIC. Head impact injuries are not believed to be life threatening if the HIC does not exceed a value of 1,000.
With most common methods of determining the impact attenuating properties of a surface, the impact of a child’s head is simulated with a metal headform. The headform is dropped onto a sample of surfacing material and the acceleration-time function of the impact is recorded. In the United States, the impact attenuation of playground surfaces is generally specified in accordance with ASTM F 1292. This standard specifies that a playground surface shall meet certain criteria when impact tested in accordance with another standard, ASTM F 355 . This latter standard describes an impact test using a 5 kg metal headform. The headform is dropped from a predetermined height and the impact recorded with an accelerometer. The acceleration-time data is processed to give g-max and HIC scores.

F-1292 specifies that in order for a surface to meet shock attenuation performance requirements at a given drop height, g-max must not exceed 200 g and HIC must not exceed 1000. The maximum height at which a surface meets these criteria is known as its critical height. The surface under particular piece of playground equipment should have a critical height value equal to or greater than the highest accessible part of the equipment

Head Injury Criterion


Explanation:
HIC* (*) Head Injury * Criterion... www.rbsirecyclage.com/aireseng.html

Check out also the following URLs which pertain to the new European standards for childrens' playgrounds (covering everything from ground covers to outdoor playground equipment):
http://www.melcourt.co.uk/play/pg13.htm
http://www.smp.co.uk/htm/en1176.htm

The pertinent European standard is EN 1177. You'll find a wealth of information if you search on that.
Good luck.
