Pass / fail criteria

Tests to BS EN 1522:1999 have three possible test outcomes:

Fail

when the bullet perforates the sample.

Pass

(splinters)
when the bullet is stopped by the sample but splinters (spall) are generated from the rear face of the specimen or test piece and the witness foil is perforated.

(Splinters –S)

Pass

(no splinters)
when the bullet is stopped by the sample and no splinters are generated from the rear face of the specimen or test piece.

(No Splinters –NS)

The results achieved were as follows:

BBX wall thickness (mm) Pass criteria achieved
100 Pass (S) BR4
140 Pass (S) BR5
215 Pass (S) BR7
