Tested for Performance and Quality Internationally

The only headband in the world that has met all the stringent international requirements to be certified CE II as protective headgear. Used in over 15 sports and activities.

The II in CE II means the safety component of the protective equipment must perform as claimed: TO REDUCE THE SEVERITY OF THE IMPACT BY SIGNIFICANTLY ABSORBING AND DISSIPATING THE FORCE ASSOCIATED WITH THE IMPACT.

Forcefield Protective Headgear™ has been independently tested at McGILL University, Canada at INTERTEK, Laboratories USA and certified by INSPEC International, United Kingdom. Tested under the same rigid conditions as those for hockey helmets for absorbing and spreading out initial impact over a larger area: the international ASTM F 1045-87 Standard Performance (drop test) Specification as well as F2439-06 for soccer injuries (head-to-head, head-to-goalpost, head-to-hard-surface). The product exceeds both standards. Awarded the CE II mark for protective headgear by the European Commission.


Tests were performed on the ForceField FFTM headband / headgear in accordance with the standard specification* for headgear used in soccer at an independent laboratory certified to test the headgear in accordance with ASTM F2439. The ForceField headband / headgear passed all tests in accordance with the protocol set forth in the standard. It should be noted that Dr. Abraham was and still is a member of the ASTM committee that was responsible in the creation of that standard and as well as the re-approvals up through 2011*.

In addition, the same tests and more rigorous testing was performed by independent laboratories in Europe. As a result of six months of independent testing, the ForceField FF Protective Headband / Headgear was awarded the CEII Mark which designated the ForceField products as “Protective Headbands.” This designation was required to legally distribute the ForceField products throughout Europe, the Far East, Canada, Australia and New Zealand.

The test results that are shown below is additional test data performed on the ForceField headgear exposing the ForceField headbands to much higher impacts that were required in the ASTM F2439 standard. The tests illustrate the effective absorption and dissipation properties of the headgear when exposed to significantly higher forces equivalent to the testing protocol applied to protective headgear used in other sports such as ice hockey and baseball.

Based upon the results of all of the tests that were performed in accordance with ASTM F2439, the undersigned has both the experience (refer to www.scientificadvisory.com) and authority to test the ForceField headgear at independent laboratories, approve and certify the results in accordance with the Standard.

The ForceField FFTM Headband- Additional Impact Testing

Drop Test Apparatus

The headform was mounted to

permit impact between the mid

anterior – crown locations.


The ForceField FFTM Headband was tested under the same rigid test conditions that a hockey helmet is tested.

The test method used was ASTM F 1045 titled “Standard Performance Specification for Ice Hockey Helmets”. In that test, the hockey helmet is a complete product containing a liner of shock absorbing material covered with a hard plastic shell which gives the helmet its form and helps spread out the initial impact over a larger area. No single impact can exceed 300Gs.

The velocity of the 41-inch drop was 4.48 meters per second.

The results averaged 252.9Gs for the headband.

The ForceField FFTM Headband passed the ASTM F 1045 test protocol.

In comparison, a bare NIKE band did not have any noticeable effect in absorbing any impact of any significance.



This report summarizes the results of preliminary testing to determine the impact absorption performance characteristics of prototype headbands for soccer.


The independent measure of interest was peak G (i.e. impact deceleration).

The dependent variable of impact velocity and energy were held constant at 1.9 m/s and 9.2 J, respectively.

An ISO headform (size L ~ medium adult) with triaxial accelerometer (Kistler) mounted at the approximate center of mass was dropped by means of a bi-rail basket guide (similar to CEN 960 for ice hockey) from a height of 30 cm (see figure 1).

Ten initial tests were conducted without any headbands mounted to provide baseline measures. Three impact per sample were conducted with approximately 30 seconds between impacts.

The initial ten impacts without headbands produced peak G values of 652.4 G’s. With the new patented headbands introduced, impact absorption (i.e. the ratio between no head band versus with headband) demonstrated values up to 83% (decrease in impact force) (average of three impacts).

Testing Protocol

The testing of the helmet insert and protective device was independently performed.

The test method used was ASTM F 1045 with a 41″ drop.

The protocol was used to determine the feasibility of the concept of adding the patented headband (1), the consistency for a variety of protective helmets and whether the results would make a significant difference in the absorption and dissipation of forces. A small change would not be useful.
