December 1997

1. Summary
The aims of these tests were to evaluate the following equipment improvements:
1) 4.5 mm locally manufactured polycarbonate heat-formed visor as replacement
for existing 3 mm imported visor.
2) An industrial safety helmet as a light weight alternative to the current
demining helmet.
3) Kevlar fabric body protection.
4) Locally manufactured body protection.
5) Locally made prodder with blast protection.
The tests were carried out by UNOCHA staff under supervision of Jan Robertz,
technical advisor. Control tests were done at the same time on standard
equipment to ensure that the tests were representative and that the new
equipment provides effective protection.
2. Visor Tests
The visor was attached to a standard UNOCHA helmet and a PMN mine was
detonated 40cm from the visor (2 cm deep under ground). The ground was medium
hard and stony.

Setting up control test using a PMN-1 mine (electrically detonated) against
a current 3mm imported visor (new) which passed this test.
The helmet is mounted on a field melon (local to Jalalabad) which simulates
a deminer's head. The melon is supported from behind by a sand bag to represent
the deminer's body. |
